I've heard a lot of plot ideas for when the story will take place, but here is my theory. I believe it takes place during KH Days/ beginning of KH2. Why? Well, the Twilight Thorn pretty much made me think of this. I believe Sora is dreaming in his pod, and some memories of Roxas are leaking INTO him, so possibly, Sora could have been fighting the Twilight Thorn just because Roxas fought it. It's just a thought that Roxas could be possibly be influencing these events, not all of them, but the ones that are chronologically impossible for Sora.
