So they're data worlds made from real worlds? Is it the real Wonderland/Agrabah/world we already visited or just a data version of them like Coded?
From what I remember during the story of the browser game it was projections of future worlds brought to life by the BoP. And then when Unchained X starts they are data worlds in a datascape that the characters can access from Daybreak Town. So it looks like they are more like the worlds from Coded making Coded even more important than it was before. Thanks Nomura.
Maybe Luxord wants Sora and Yozora to work together? Thereby having Yozora encounter Sora in the Final World so that Sora's connection to him could be Sora's key to returning from the Final World?
