AU Background
Note: This AU contains/involves spoilers for every conceivable part of Kingdom Hearts: 358/2 Days, as well as major spoilers for most of the rest of the series.
The Bridge Arc will contain some and Arc 2 (which is not up yet) will contain copious spoilers for KH3D.
Also Note: Summary is slightly out of date pertaining to recent world additions and the addition of Namine's character development arc.
The short version:
Arc 1
Sora's awakening is delayed so that his memories can be restored in a way that lets Xion and Roxas live. They go on the run from the Organization and try not to use their Keyblades so Kingdom Hearts won't be completed as quickly. Axel eventually joins them, and the Organization tries to capture/destroy them, or cause problems that force her and Roxas to use their Keyblades. They befriend not just Riku and Namine, but King Mickey and Kairi as well.
Eventually Xion destabilizes and starts absorbing memories again. After a lot of debate, they convince DiZ to reprogram her so she's fully stable. Namine discovers Ventus' memories in Sora's heart and during their worldhopping they search for Aqua in the Realm of Darkness. They do eventually find her, but Axel sacrifices himself defending Roxas and Xion. Aqua takes it upon herself to watch over them in the final weeks leading up to Sora's awakening. Kingdom Hearts is almost completed the day Sora wakes up - stopped only by the timely intervention of DiZ and his encoder.
Bridge Arc
Sora wakes up at Disney Castle to find Riku, Kairi, Namine, Mickey, and Aqua (as well as Donald and Goofy of course) all there waiting for him. Sora checks on the worlds as he gets his feet back under him. He eventually meets Roxas and Xion on a break at Disney Castle. Eventually the DI trio return home, with Roxas, Xion, and Namine in tow. Kairi takes Namine to meet her adoptive family, while Sora takes Roxas and Xion home. After a fair bit of explanations and discussions, Sora's parents agree to add Roxas and Xion to their family. Cue awkward and difficult but overall cute adjustment period.
Eventually Sora throws a birthday party for Xion and Roxas since they missed theirs, and during the party Lea turns up, prompting a very emotional reunion. Things are quiet for a little while, before the Organization strikes. They distract the others and kidnap Xion in the hopes of reprogramming her to become one of the thirteen Xehanort vessels. This leads to an attack on The World That Never Was to try to get her back, which is successful in doing so and also in destroying most of what's left of Organization XIII, setting the stage for the next Arc.
Arc 2
Still in planning stages. Will contain copius amounts of KH3D spoilers when done
Full Version:
Arc 1
On Day 355, as Roxas attempts to leave the Organization, he meets Axel in the streets of The World that Never Was. Only instead of letting Roxas go, Axel runs after him, and explains to Roxas several things, including who Sora is, who Roxas is to him, and the reason that both Roxas and Xion were in the Organization. Though Roxas is angry, they both forstall a confrontation in order to run after Xion, whom Axel says they need to stop her from doing whatever it is she plans to do.
The next day, when Xion is speaking to Namine about returning to Sora, both girls are surprised when Roxas and Axel suddenly burst in on them. Despite Xion's protests, Axel pushes Namine until she admits that it could be possible to extract Sora's memories from both Xion and Roxas in theory, however the process would take far too long and DiZ would never allow it.
At that point, DiZ himself appears to see if Namine is finished speaking with Xion yet, and is shocked to find both obstacles to Sora's awakening right in front of him. He orders Namine to incapacitate one or both (the same way she did the Riku Replica at Castle Oblivion), but when she refuses, Axel causes a diversion and she and Roxas and Xion escape through a darkness corridor.
After sufficiently distracting DiZ, Axel reports back in to the Organization, then sets off to find Roxas, Xion and Namine. He finds them in Wonderland (where he'd told Roxas to go), and the four of them come up with a plan of action. Axel would stay behind at the Organization and cover their tracks, as well as check the mission roster to make sure the kids were never where another Organization member was. Meanwhile the kids would stay in hiding, and avoid using their Keyblades so Kingdom Hearts would not be completed and so that the sudden production of hearts in a particular would wouldn't clue the Organization in on the kids' location.
They part ways, and Roxas and Xion lay low for a while, first at Olympus Coliseum, then in Halloween Town. While they're in Halloween Town, they're found by Riku, and explain the situation to him. At first he's reluctant, but after hearing the full plan he agrees with it - he knows that Namine's assessment about Sora not reacting well if Roxas and Xion were forced to die for him is correct.
He then leaves to find King Mickey and discuss the new developments. Later, he comes back to take Namine to somewhere where she can work safely and undiscovered (and NOT under DiZ's eye), but before the two pairs part ways, Namine uses her powers to put a sort of freeze the memories Xion contains and is comprised of, something that whould temporarily keep Sora's memories from leaking from Roxas to her (and consequently keeping her from absorbing Roxas's own powers and killing him), but would make manipulating the memories a much slower process. She warns that the effect is temporary, though, and that they'll need to find a more permanent solution. When Axel turns up and asks where Namine is, the kids explain (as per her and Riku's request, knowing that Axel doesn't trust Riku at all) that she had to go to Castle Oblivion to continue her work.
Meanwhile, on the remote world of Destiny Islands, a girl named Kairi - struggling to remember a boy she knows she once knew - puts a letter in a bottle and drops it in the ocean, resolving to go find him as soon as she can find a way.
Riku and Namine eventually find King, and explain the situation. They take Namine to Disney Castle, and Mickey agrees to let it sort of become their base of operations. At that point, they part ways again, Mickey to do... whatever it is Mickey does, Riku to try and find Roxas and Xion and explain the current developments.
Axel maintains his role in the Organization for as long as possible to get information that would give Roxas and Xion an advantage, including a week or so side mission to Castle Oblivion where he scours what's left of Vexen's lab to try to find any remaining information about the Replica Project. Unfortunately, there isn't much to find. Eventually, after a month and half, Saix (who already suspects him) catches Axel with his roster, causing Axel's double-agent playing to come to light. He flees the Organization, eventually rejoining Roxas and Xion.
The Organization, meanwhile, quickly realizes - even prior to Axel's deserting - that Roxas and Xion aren't using their Keyblades to collect hearts. Particularly once Axel's loyalties are clear, they begin to send Organization members to track down and capture at least one Keyblade wielder, as well as destroy the other and Axel. Initially they target Xion, until enough time passes that it becomes clear that something is stopping her from absorbing Roxas, at which point they become less picky.
They travel from world to work for a time, Roxas and Xion learning new things from the new worlds they visit that they've never seen before. Unfortunately, after a visit to Port Royal, both catch colds, leaving Axel to care for them while they bed down in a hotel in 101 Dalmatians London. Roxas eventually improves, while Xion's condition worsens, until she loses control of a fire spell during a fever-induced nightmare, attracting the attention of Riku, who has recently arrived and been searching for them. During a tense encounter, Riku explains that King Mickey has allowed his own world of Disney Castle to be a sort of safe haven for the trio when they need it - and it certainly looked as though they needed it then.
They travel to Disney Castle, and find Namine there. Queen Minnie uses some advanced white magic to bring Xion's cold back to a manageable level, and the trio crashes at Disney Castle while she and Roxas finish recovering. They also meet Namine there, who explains that she has potentially found a more concrete, faster way to allow Roxas and particularly Xion to live: Namine would untangle their memories, and the memories of Kairi that Xion is comprised of would slowly be replaced with those of Namine herself and Castle Oblivion - still memories of Sora's, but not ones he would need to wake up.
Around three-ish months after the events of 358/2 Days would have ended, the Organization finds Kairi's letter to Sora in the Realm of Darkness. The next time an Organization member finds Roxas, Axel, and Xion, they toss them the letter and attempt to use it as proof that they are holding Kairi hostage. They're skeptical (after all, you can find a letter anywhere, even forge it) but take the letter back to Disney Castle, where they run into Riku and explain what happened, and what the Organization claimed. Riku verifies that the letter looks like it was written by Kairi, though he too is skeptical and goes to check Destiny Islands just to be on the safe side.
At the same time, thanks to Namine's efforts, Kairi's memories are starting to clear about Sora, enough that she becomes more determined than ever to go find him and Riku, rather than waiting. The desire is strong enough that she unconciously invokes the same process that Beast did in Kingdom Hearts, and transports herself through strength of will to a world with which she already has close connections: Hollow Bastion. Thus, when Riku arrives at Destiny Islands to check, she isn't there.
He reports back, and a little bit of panic sets in. They're still skeptical about whether or not the Organization actually has Kairi, and it's just as likely that this is a trap. They come up with a plan: Roxas, Axel and Xion would try to quickly see if she was in The World That Never Was, doing their best to anticipate any traps laid for them, and Riku would scour the other worlds looking for Kairi. Because of the risky nature of the Days trio's job, they agreed to a rendezvous with Riku afterwards, and he said he would come looking if they were late.
Well, to put a long story short, they were late. No matter how many traps they anticipated, they still ended up facing down at least three other Organization members who were lying in wait for them. Xion was knocked out in the process of fleeing, before they could get to a darkness corridor. However, the most successful ambush came from an entirely unexpected source, after they'd landed at the rendezvous point.
DiZ had been furious that his plan had been essentially brushed aside and derailed in under a day. He refused to hand over the unconscious Sora, Donald, and Goofy (thus slowing and limiting Namine's ability to work on them further), and instead worked to come up with a plan to try to strongarm his revenge back onto the table. Using an invention he'd developed in the months since Namine had fled, he stunned Roxas and Axel, and took the former and Xion back with him, where he threw the two into the Digital Twilight Town. Because he did not have Namine as his ally, they retained their memories and consciousness of what was really going on. However, he did not modify the program to incorporate them, thus leaving Roxas and Xion stuck in the state where none of the people in the program could see, hear, touch, or notice them at all. Additionally, DiZ manipulates the world around them to keep them away from the exit while he figures out what to do with them.
Riku, meanwhile, manages to successfully locate Kairi in Hollow Bastion, where she's been hanging out with the Restoration Committee in the hopes of finding a way to either repeat the process that got her there from Destiny Islands, or find some other way of traveling between worlds. In particular, she hoped that Cid might build a Gummi ship she can use - despite Cid's insistence that the worlds were separated now. He takes Kairi back to Disney Castle, then goes to meet the Days trio at the rendezvous.
He arrives, sees that they're late, and goes looking, and comes back just after DiZ's attack. He helps Axel get himself back on his feet and send him in the right direction - since while neither is sure who exactly took Roxas and Xion, they know that the person can use darkness corridors. After that point, both go their separate ways, looking for ways to find and get Roxas and Xion back.
Axel goes back to TWTNW, where he finds out from Demyx that the Organization doesn't have them, and from the computer systems, he finds out they're in Twilight Town. Riku goes back to Disney Castle and explains some of the situation to Kairi and confers with Namine and possibly Mickey as well, if he's there. Namine comes to the same conclusion - that they're in Twilight Town, and realizes what must've happened. At this point Axel heads back to Disney Castle to confer with Riku and come up with the plan they eventually use.
Riku and Kairi distract DiZ as best they can, while Axel ventures into the Digital Twilight Town, finds Roxas and Xion and they attempt to escape. DiZ catches them and attempts to eject Axel from the system, but through the Power of Friendship, the three all get ejected together and with the help of Kairi and Riku escape to Disney Castle where they promptly collapse in an exhausted pile and sleep. Riku and Kairi, meanwhile, stay behind to try to convince DiZ to NEVER TRY SOMETHING LIKE THIS AGAIN. At some point during the distracting/defending/discussion, Riku awakens to Way to Dawn.
After this point, Roxas and Xion in general are very wary and subdued. In order to try and brighten the mood and cheer them up, Kairi and Axel conspire together and - with a little help from the residents of Disney Castle - introduce them - and Namine - to Christmas. During the celebration, Riku takes off his blindfold for the first time that many of them can remember (this marks the beginning of a slow process where he wears it less and less as he gains better control over the darkness in his own heart).
Things begin to calm down. Kairi establishes herself as the person who keeps everyone informed and up-to-date and just overall keeps an eye on everything. This keeps her satisfied for a little while, though she slowly starts to grow more unsettled at still feeling left out/behind by the others. Eventually she starts trying to find a way to fight/participate in ways she feels will be able to help the others more. The potential for her Keyblade is there, but her frustrations and focusing too much on feeling left out and behind keep her from being able to summon it. Meanwhile, the Days trio, especially Roxas and Xion, slowly begin to befriend Kairi, Mickey and probably the other residents of Disney Castle.
The Organization at this point does begin to shift slightly. They still send members to try to track down and capture/destroy Xion, Roxas and Axel, but they also begin trying to manipulate the worlds, and their villains to increase the Heartless populations in said worlds drastically. The idea is, if the Heartless start causing enough trouble, someone will have to help, or else leave the worlds to be overrun completely. It slowly works - Roxas and Xion start finding themselves in situations where they are forced to use their Keyblades to fight incredibly numerous or incredibly powerful Heartless.
Still, for several months after escaping the Digital Twilight Town, things are a quiet waiting game, waiting for Sora to wake up. They travel, they spend time with their friends. Kairi conspires with Roxas and Xion to celebrate Axel's birhtday, and later that month, Axel and Kairi conspire again and throw Roxas and Xion and Namine their first birthday for the three of them's second birthday.
A little over a year after 358/2 Days would have ended, Xion, Roxas and Axel are still trying to stop trouble that's appearing in the worlds more and more frequently, as the Organization starts pushing heart production further. Meanwhile, DiZ comes to the conclusion that going with a plan he doesn't like is better than not having a hand in Organization XIII's downfall. He contacts King Mickey and agrees to relinquish control of Sora, Donald, and Goofy to him, Riku, and Namine and offers his aid in stopping Organization XIII. He also reveals his identity as Ansem the Wise and explains a his connections to the Organization's founders, in order to try to regain some of the trust he's lost with Riku (who didn't really trust him that much in the first place) and Mickey (who has heard stories from Riku). The four of them (DiZ and Sora, Donald and Goofy) are transplanted to Disney Castle.
Unfortunately, at almost the exact same time, Namine discovers that the seal she put on Xion to keep her from absorbing memories has finally fallen apart, and that something needs to be done or they will essentially be back where they started, and either Xion or Roxas (or even both) will have to die. She explains this to Xion the next time she and Roxas and Axel visit, and Riku suggests they ask DiZ, who - as Xemnas and Vexen's former master - has the most likely chance of being able to successfully reprogram Xion so that she no longer absorbs memories.
When asked, DiZ blatantly refuses to help: while he may have agreed to hand over Sora and help take down Organization XIII, his deep prejudice against nobodies and replicas remains. Xion realizes that, like Saix, he cannot see her face, and blatantly calls him out on his hypocrisy. The Days trio return to scouring the worlds, looking for anything that might be able to help them in between dodging Organization members and stopping trouble in the worlds.
It takes a good three months before DiZ comes around - three months where a lot of people either talk to him or try to convince him: Mickey, Kairi, Riku, at least one conversation near the end with Axel (Radiant Garden residents/references); not to mention him just seeing the Days trio interact when they visit Disney Castle. At some point during her discussion with DiZ, Kairi's defending the people and bonds she's gained allows her to finally summon Destiny's Embrace. Between all that, he's slowly forced to re-evaluate his position on their existences; eventually he even sees Xion's face, around when he finally he relents and agrees to reprogram her, shortly after Christmas that year.
A month later, Namine requests to speak with everyone, and once gathered, she brings up that she has been finding memories of another person in Sora's heart - one who looks exactly like Roxas. Between King Mickey and a little bit from Axel, essentials of the Aqua, Terra and Ventus' story come out, as well as questions about the connection between Ven and Sora. While they aren't entirely sure what they can do to fix all that's gone wrong (or even if they can) those who have the ability to use darkness corridors - Riku and the Days Trio - decide to search the Realm of Darkness when they have the chance to see if they can at least find Aqua.
Eventually they do manage to find her, however when they do so the four of them are set upon by a very dangerous, violent denizen of the Realm of Darkness (the Red Eyes from BBSFM fame). During the fight, the Red Eyes aims a nasty attack at Xion and Axel shoves her out of the way, taking the hit and sustaining a critical amount damage. By the time Aqua and the kids are able to finish off the Heartless and get over to him, it's too late to undo the damage. Axel tells the kids that they made him feel like he had a heart before fading away.
Distraught, Xion and Roxas get Aqua back to Disney Castle. Riku, Namine and Mickey explain to Aqua what all has happened, while Kairi attempts to console Roxas and Xion. They take a brief break to attempt to recover, before they have to leave again, to stop the problems the Organization is still causing. Meanwhile, after consulting with Yen Sid, Aqua agrees to remain relatively hidden for the time being, partially so she can readjust to life in the Realm of Light, so she can train and help the younger generations, and so that her presence in the Realm of Light might remain unknown to the Organization.
At this point, it's a very tense waiting game while waiting for Sora. As Namine's work nears completion, however, it becomes clear that Kingdom Hearts too is, despite their best efforts, nearing completion as well. DiZ, seeing this, takes his Data Encoder, sneaks to The World That Never Was, and sacrifices himself to destroy it as he does in canon.
And then, Namine completes her work, and Sora wakes up.
Bridge Arc
Some of this arc is still in the planning stages
When Sora wakes up, he sees Goofy and Donald waiting outside his pod, however, he's surprised (and delighted) to find that there are a few other special people there too - Riku, Kairi, Mickey, and two other people he vaguely recognizes (the first is Namine, the second he soon finds out, is Aqua). He soon finds out he's in Disney Castle, the world that Mickey, Donald and Goofy come from.
At the same time, Sora discovers something else - that he's been asleep for three years, and among other things, has slept through most of his growth spurt. The group at Disney Castle take a little time to give Sora some preliminary explanations about what has happened, and to give him some time to get his feet back under him - metaphorically and literally, as three years worth of growth he wasn't expecting takes some getting used to.
Once he's ready, the group travels to Mysterious Tower to speak with Yen Sid. Yen Sid explains the current status of the worlds, and gives a similar explanation about Organization XIII and Nobodies. However, unlike in canon, Yen Sid is aware of Axel, Roxas, and Xion's existence, and makes it a point to Sora that not all Nobodies are cut from the same cloth. He also tells Sora that, with the destruction of the Kingdom Hearts of People's Hearts that Xemnas was creating, they needed to wait and see what the Organization's next move would be. In the meantime, Yen Sid tasks Sora with checking the status of the worlds, in order to help ascertain the general state of things and also (though this part is unspoken) to help Sora catch up with everyone else, skill-wise.
Sora travels the worlds, sometimes with Donald and Goofy, sometimes with Riku and Kairi. There are plenty of situations that have already been resolved by the time he wakes up - for instance, Beast and Belle have already broken Beast's curse and he's regained his human form. The repairs to Hollow Bastion are well underway, and given that Riku and Kairi helped Tron out at some point in Arc 1 (haven't decided when yet), it has regained its original name of Radiant Garden. Overall, while there are some problems still, very few of them are mass effusions of Heartless.
In addition to this world hopping, Sora and his friends occasionally stop by Disney Castle to take a break. And throught his journeys, Sora keeps an eye out for two people named Roxas and Xion, whom Riku and Kairi and the others have explained that they are two very important people - both in how they helped while he was asleep and in who they were to him - but refused to explain any further than that, saying that Roxas and Xion would have to explain themselves.
Eventually Sora does meet Xion during one of these breaks, and she explains what she is - how she was made to absorb his memories and how she had kept him asleep for so much longer than he cold have been if she had not selfishly (at least in her mind) not wanted to disappear. Sora reassures her that he doesn't mind, and is in fact happy with how things have turned out. Sora later meets Roxas, however, but the meeting does not go as smoothly. In the wake of Axel's loss, Roxas - with nowhere else to really vent it on - misplaces a lot of his anger on Sora, enough to cause a lot of friction between the two, despite Sora's best attempts.
Eventually, Sora has checked the status of all the worlds, and there's still no sign of what the Organization is up to. In the end, he decides to return home, along with Riku and Kairi as well as Namine, Roxas, and Xion (Roxas only really coming at Xion's request). From there, Sora goes home to his parents and, after a long series of explanations, introduces Roxas and Xion to them in what amounts to "Hi I accidentally made heartbabies/siblings can we keep them?" In the end, relieved to see their son home again, they agree, and Roxas and Xion become like siblings to him.
The night that this agreement was reached, however, Roxas leaves the house and is shortly followed by Xion. You see, the idea of getting a family was actually distressing to him after Axel's death - having more meant having more to lose. Xion finds him at the beach, finally dealing with some of his grief over Axel's death that the situation brought to the surface. The two hug and cry, which is how Sora eventually finds them and does dorky things to try to cheer them both up. They return home, and from there Sora's relationship with Roxas, while not perfect, improves dramatically. Thus begins a series of two or so months where Sora's family adjusts to being back together again, not to mention its increased size.
During all this time, Lea awakens in Hollow Bastion and attempts to figure out what to do. He has a lot of concerns and worries about going back to see Roxas and Xion - potentially upsetting them after they've come to terms with his death, the fact that he has a heart now... Eventually he lands in the world of Lilo and Stitch, where he manages by chance to speak with Lilo who convinces him - by sharing her own situation - to go back to Roxas and Xion. He sets out to look for them.
Other conversations take place, such as Namine apologizing to Sora's parents and so on and so forth. Eventually, Sora discovers that in the aftermath of Axel's death and his awakening, Roxas and Xion missed their birthday. Deciding that this won't do, he throws a birthday party for them. During that birthday party, strange things start happening (particularly a set of re-lighting candles) and then to the surprise of everyone, Axel - or rather Lea - reappears. A little while passes while things settle down.
However, at this point, the Organization decides they've given the group enough downtime to lull them into a false sense of security. It's then that they choose to strike.
The end of the bridge arc is still in planning stages, but the notes/rough outline can be found here.
Arc 2
Arc 2 is still very much in the planning stages. It will eventually include a lot of KH3D spoilers though, so be forewarned.
The Bridge Arc will contain some and Arc 2 (which is not up yet) will contain copious spoilers for KH3D.
Also Note: Summary is slightly out of date pertaining to recent world additions and the addition of Namine's character development arc.

Roxas eventually improves, while Xion's condition worsens, until she loses control of a fire spell during a fever-induced nightmare, attracting the attention of Riku, who has recently arrived and been searching for them. During a tense encounter, Riku explains that King Mickey has allowed his own world of Disney Castle to be a sort of safe haven for the trio when they need it - and it certainly looked as though they needed it then.
They travel to Disney Castle, and find Namine there. Queen Minnie uses some advanced white magic to bring Xion's cold back to a manageable level, and the trio crashes at Disney Castle while she and Roxas finish recovering. They also meet Namine there, who explains that she has potentially found a more concrete, faster way to allow Roxas and particularly Xion to live: Namine would untangle their memories, and the memories of Kairi that Xion is comprised of would slowly be replaced with those of Namine herself and Castle Oblivion - still memories of Sora's, but not ones he would need to wake up.
Around three-ish months after the events of 358/2 Days would have ended, the Organization finds Kairi's letter to Sora in the Realm of Darkness. The next time an Organization member finds Roxas, Axel, and Xion, they toss them the letter and attempt to use it as proof that they are holding Kairi hostage. They're skeptical (after all, you can find a letter anywhere, even forge it) but take the letter back to Disney Castle, where they run into Riku and explain what happened, and what the Organization claimed. Riku verifies that the letter looks like it was written by Kairi, though he too is skeptical and goes to check Destiny Islands just to be on the safe side.
At the same time, thanks to Namine's efforts, Kairi's memories are starting to clear about Sora, enough that she becomes more determined than ever to go find him and Riku, rather than waiting. The desire is strong enough that she unconciously invokes the same process that Beast did in Kingdom Hearts, and transports herself through strength of will to a world with which she already has close connections: Hollow Bastion. Thus, when Riku arrives at Destiny Islands to check, she isn't there.
He reports back, and a little bit of panic sets in. They're still skeptical about whether or not the Organization actually has Kairi, and it's just as likely that this is a trap. They come up with a plan: Roxas, Axel and Xion would try to quickly see if she was in The World That Never Was, doing their best to anticipate any traps laid for them, and Riku would scour the other worlds looking for Kairi. Because of the risky nature of the Days trio's job, they agreed to a rendezvous with Riku afterwards, and he said he would come looking if they were late.
Well, to put a long story short, they were late. No matter how many traps they anticipated, they still ended up facing down at least three other Organization members who were lying in wait for them. Xion was knocked out in the process of fleeing, before they could get to a darkness corridor. However, the most successful ambush came from an entirely unexpected source, after they'd landed at the rendezvous point.
DiZ had been furious that his plan had been essentially brushed aside and derailed in under a day. He refused to hand over the unconscious Sora, Donald, and Goofy (thus slowing and limiting Namine's ability to work on them further), and instead worked to come up with a plan to try to strongarm his revenge back onto the table. Using an invention he'd developed in the months since Namine had fled, he stunned Roxas and Axel, and took the former and Xion back with him, where he threw the two into the Digital Twilight Town. Because he did not have Namine as his ally, they retained their memories and consciousness of what was really going on. However, he did not modify the program to incorporate them, thus leaving Roxas and Xion stuck in the state where none of the people in the program could see, hear, touch, or notice them at all. Additionally, DiZ manipulates the world around them to keep them away from the exit while he figures out what to do with them.
Riku, meanwhile, manages to successfully locate Kairi in Hollow Bastion, where she's been hanging out with the Restoration Committee in the hopes of finding a way to either repeat the process that got her there from Destiny Islands, or find some other way of traveling between worlds. In particular, she hoped that Cid might build a Gummi ship she can use - despite Cid's insistence that the worlds were separated now. He takes Kairi back to Disney Castle, then goes to meet the Days trio at the rendezvous.
He arrives, sees that they're late, and goes looking, and comes back just after DiZ's attack. He helps Axel get himself back on his feet and send him in the right direction - since while neither is sure who exactly took Roxas and Xion, they know that the person can use darkness corridors. After that point, both go their separate ways, looking for ways to find and get Roxas and Xion back.
Axel goes back to TWTNW, where he finds out from Demyx that the Organization doesn't have them, and from the computer systems, he finds out they're in Twilight Town. Riku goes back to Disney Castle and explains some of the situation to Kairi and confers with Namine and possibly Mickey as well, if he's there. Namine comes to the same conclusion - that they're in Twilight Town, and realizes what must've happened. At this point Axel heads back to Disney Castle to confer with Riku and come up with the plan they eventually use.
Riku and Kairi distract DiZ as best they can, while Axel ventures into the Digital Twilight Town, finds Roxas and Xion and they attempt to escape. DiZ catches them and attempts to eject Axel from the system, but through the Power of Friendship, the three all get ejected together and with the help of Kairi and Riku escape to Disney Castle where they promptly collapse in an exhausted pile and sleep. Riku and Kairi, meanwhile, stay behind to try to convince DiZ to NEVER TRY SOMETHING LIKE THIS AGAIN. At some point during the distracting/defending/discussion, Riku awakens to Way to Dawn.
After this point, Roxas and Xion in general are very wary and subdued. In order to try and brighten the mood and cheer them up, Kairi and Axel conspire together and - with a little help from the residents of Disney Castle - introduce them - and Namine - to Christmas. During the celebration, Riku takes off his blindfold for the first time that many of them can remember (this marks the beginning of a slow process where he wears it less and less as he gains better control over the darkness in his own heart).
Things begin to calm down. Kairi establishes herself as the person who keeps everyone informed and up-to-date and just overall keeps an eye on everything. This keeps her satisfied for a little while, though she slowly starts to grow more unsettled at still feeling left out/behind by the others. Eventually she starts trying to find a way to fight/participate in ways she feels will be able to help the others more. The potential for her Keyblade is there, but her frustrations and focusing too much on feeling left out and behind keep her from being able to summon it. Meanwhile, the Days trio, especially Roxas and Xion, slowly begin to befriend Kairi, Mickey and probably the other residents of Disney Castle.
The Organization at this point does begin to shift slightly. They still send members to try to track down and capture/destroy Xion, Roxas and Axel, but they also begin trying to manipulate the worlds, and their villains to increase the Heartless populations in said worlds drastically. The idea is, if the Heartless start causing enough trouble, someone will have to help, or else leave the worlds to be overrun completely. It slowly works - Roxas and Xion start finding themselves in situations where they are forced to use their Keyblades to fight incredibly numerous or incredibly powerful Heartless.
Still, for several months after escaping the Digital Twilight Town, things are a quiet waiting game, waiting for Sora to wake up. They travel, they spend time with their friends. Kairi conspires with Roxas and Xion to celebrate Axel's birhtday, and later that month, Axel and Kairi conspire again and throw Roxas and Xion and Namine their first birthday for the three of them's second birthday.
A little over a year after 358/2 Days would have ended, Xion, Roxas and Axel are still trying to stop trouble that's appearing in the worlds more and more frequently, as the Organization starts pushing heart production further. Meanwhile, DiZ comes to the conclusion that going with a plan he doesn't like is better than not having a hand in Organization XIII's downfall. He contacts King Mickey and agrees to relinquish control of Sora, Donald, and Goofy to him, Riku, and Namine and offers his aid in stopping Organization XIII. He also reveals his identity as Ansem the Wise and explains a his connections to the Organization's founders, in order to try to regain some of the trust he's lost with Riku (who didn't really trust him that much in the first place) and Mickey (who has heard stories from Riku). The four of them (DiZ and Sora, Donald and Goofy) are transplanted to Disney Castle.
Unfortunately, at almost the exact same time, Namine discovers that the seal she put on Xion to keep her from absorbing memories has finally fallen apart, and that something needs to be done or they will essentially be back where they started, and either Xion or Roxas (or even both) will have to die. She explains this to Xion the next time she and Roxas and Axel visit, and Riku suggests they ask DiZ, who - as Xemnas and Vexen's former master - has the most likely chance of being able to successfully reprogram Xion so that she no longer absorbs memories.
When asked, DiZ blatantly refuses to help: while he may have agreed to hand over Sora and help take down Organization XIII, his deep prejudice against nobodies and replicas remains. Xion realizes that, like Saix, he cannot see her face, and blatantly calls him out on his hypocrisy. The Days trio return to scouring the worlds, looking for anything that might be able to help them in between dodging Organization members and stopping trouble in the worlds.
It takes a good three months before DiZ comes around - three months where a lot of people either talk to him or try to convince him: Mickey, Kairi, Riku, at least one conversation near the end with Axel (Radiant Garden residents/references); not to mention him just seeing the Days trio interact when they visit Disney Castle. At some point during her discussion with DiZ, Kairi's defending the people and bonds she's gained allows her to finally summon Destiny's Embrace. Between all that, he's slowly forced to re-evaluate his position on their existences; eventually he even sees Xion's face, around when he finally he relents and agrees to reprogram her, shortly after Christmas that year.
A month later, Namine requests to speak with everyone, and once gathered, she brings up that she has been finding memories of another person in Sora's heart - one who looks exactly like Roxas. Between King Mickey and a little bit from Axel, essentials of the Aqua, Terra and Ventus' story come out, as well as questions about the connection between Ven and Sora. While they aren't entirely sure what they can do to fix all that's gone wrong (or even if they can) those who have the ability to use darkness corridors - Riku and the Days Trio - decide to search the Realm of Darkness when they have the chance to see if they can at least find Aqua.
Eventually they do manage to find her, however when they do so the four of them are set upon by a very dangerous, violent denizen of the Realm of Darkness (the Red Eyes from BBSFM fame). During the fight, the Red Eyes aims a nasty attack at Xion and Axel shoves her out of the way, taking the hit and sustaining a critical amount damage. By the time Aqua and the kids are able to finish off the Heartless and get over to him, it's too late to undo the damage. Axel tells the kids that they made him feel like he had a heart before fading away.
Distraught, Xion and Roxas get Aqua back to Disney Castle. Riku, Namine and Mickey explain to Aqua what all has happened, while Kairi attempts to console Roxas and Xion. They take a brief break to attempt to recover, before they have to leave again, to stop the problems the Organization is still causing. Meanwhile, after consulting with Yen Sid, Aqua agrees to remain relatively hidden for the time being, partially so she can readjust to life in the Realm of Light, so she can train and help the younger generations, and so that her presence in the Realm of Light might remain unknown to the Organization.
At this point, it's a very tense waiting game while waiting for Sora. As Namine's work nears completion, however, it becomes clear that Kingdom Hearts too is, despite their best efforts, nearing completion as well. DiZ, seeing this, takes his Data Encoder, sneaks to The World That Never Was, and sacrifices himself to destroy it as he does in canon.
And then, Namine completes her work, and Sora wakes up.
Bridge Arc
Some of this arc is still in the planning stages
When Sora wakes up, he sees Goofy and Donald waiting outside his pod, however, he's surprised (and delighted) to find that there are a few other special people there too - Riku, Kairi, Mickey, and two other people he vaguely recognizes (the first is Namine, the second he soon finds out, is Aqua). He soon finds out he's in Disney Castle, the world that Mickey, Donald and Goofy come from.
At the same time, Sora discovers something else - that he's been asleep for three years, and among other things, has slept through most of his growth spurt. The group at Disney Castle take a little time to give Sora some preliminary explanations about what has happened, and to give him some time to get his feet back under him - metaphorically and literally, as three years worth of growth he wasn't expecting takes some getting used to.
Once he's ready, the group travels to Mysterious Tower to speak with Yen Sid. Yen Sid explains the current status of the worlds, and gives a similar explanation about Organization XIII and Nobodies. However, unlike in canon, Yen Sid is aware of Axel, Roxas, and Xion's existence, and makes it a point to Sora that not all Nobodies are cut from the same cloth. He also tells Sora that, with the destruction of the Kingdom Hearts of People's Hearts that Xemnas was creating, they needed to wait and see what the Organization's next move would be. In the meantime, Yen Sid tasks Sora with checking the status of the worlds, in order to help ascertain the general state of things and also (though this part is unspoken) to help Sora catch up with everyone else, skill-wise.
Sora travels the worlds, sometimes with Donald and Goofy, sometimes with Riku and Kairi. There are plenty of situations that have already been resolved by the time he wakes up - for instance, Beast and Belle have already broken Beast's curse and he's regained his human form. The repairs to Hollow Bastion are well underway, and given that Riku and Kairi helped Tron out at some point in Arc 1 (haven't decided when yet), it has regained its original name of Radiant Garden. Overall, while there are some problems still, very few of them are mass effusions of Heartless.
In addition to this world hopping, Sora and his friends occasionally stop by Disney Castle to take a break. And throught his journeys, Sora keeps an eye out for two people named Roxas and Xion, whom Riku and Kairi and the others have explained that they are two very important people - both in how they helped while he was asleep and in who they were to him - but refused to explain any further than that, saying that Roxas and Xion would have to explain themselves.
Eventually Sora does meet Xion during one of these breaks, and she explains what she is - how she was made to absorb his memories and how she had kept him asleep for so much longer than he cold have been if she had not selfishly (at least in her mind) not wanted to disappear. Sora reassures her that he doesn't mind, and is in fact happy with how things have turned out. Sora later meets Roxas, however, but the meeting does not go as smoothly. In the wake of Axel's loss, Roxas - with nowhere else to really vent it on - misplaces a lot of his anger on Sora, enough to cause a lot of friction between the two, despite Sora's best attempts.
Eventually, Sora has checked the status of all the worlds, and there's still no sign of what the Organization is up to. In the end, he decides to return home, along with Riku and Kairi as well as Namine, Roxas, and Xion (Roxas only really coming at Xion's request). From there, Sora goes home to his parents and, after a long series of explanations, introduces Roxas and Xion to them in what amounts to "Hi I accidentally made heartbabies/siblings can we keep them?" In the end, relieved to see their son home again, they agree, and Roxas and Xion become like siblings to him.
The night that this agreement was reached, however, Roxas leaves the house and is shortly followed by Xion. You see, the idea of getting a family was actually distressing to him after Axel's death - having more meant having more to lose. Xion finds him at the beach, finally dealing with some of his grief over Axel's death that the situation brought to the surface. The two hug and cry, which is how Sora eventually finds them and does dorky things to try to cheer them both up. They return home, and from there Sora's relationship with Roxas, while not perfect, improves dramatically. Thus begins a series of two or so months where Sora's family adjusts to being back together again, not to mention its increased size.
During all this time, Lea awakens in Hollow Bastion and attempts to figure out what to do. He has a lot of concerns and worries about going back to see Roxas and Xion - potentially upsetting them after they've come to terms with his death, the fact that he has a heart now... Eventually he lands in the world of Lilo and Stitch, where he manages by chance to speak with Lilo who convinces him - by sharing her own situation - to go back to Roxas and Xion. He sets out to look for them.
Other conversations take place, such as Namine apologizing to Sora's parents and so on and so forth. Eventually, Sora discovers that in the aftermath of Axel's death and his awakening, Roxas and Xion missed their birthday. Deciding that this won't do, he throws a birthday party for them. During that birthday party, strange things start happening (particularly a set of re-lighting candles) and then to the surprise of everyone, Axel - or rather Lea - reappears. A little while passes while things settle down.
However, at this point, the Organization decides they've given the group enough downtime to lull them into a false sense of security. It's then that they choose to strike.
The end of the bridge arc is still in planning stages, but the notes/rough outline can be found here.
Arc 2
Arc 2 is still very much in the planning stages. It will eventually include a lot of KH3D spoilers though, so be forewarned.
