Alrighty *cracks knuckles*

I actually kept a list of corrections and add-ons while reading this... so here goes.

Red Cloaked Unknown is NOT ansem. sorta. he is referred to as "both Ansem and Not Ansem" in those words from in game text (i forget by who, i believe in Final Mix by Enigma. Also, Red Cloaked Unknown's name is Diz.

Vixen and Vexen are two different people. one male... one female. if you can't figure which is which...then yeah.... just read on.

It's confirmed by Tetsuo Nomura that one of the Unknowns IS riku, and it's HEAVILY HEAVILY HEAVILY suggested that he is the blindfolded Unknown from ASAS and Deep Dive

BHK (Blonde Haired Kid) is Believed to be the Dual Wielding Unknown, and is also alluded to be in league with Riku and the Glowing Eyed Unknown b/c of Deep Dive text which reads "we'll go together" and puts those three face on screen immediately after, blended together. (also, my speculation is that the Glowing Eyed Unknown is Sora's Father, or much less likely riku's. The Unknown on the rock in deep Dive tells him "he looks just like you" and zooms to a picture of Sora, and the glowing eyed unknown is definitely not BHK, so yeah.

BHK is also confirmed (again, Nomura Interview) to be protecting Sora. from what, it's not specified.

Auron = Good. in the E3 trailer you see him fighting both Hades and Cerberus to protect Sora. Nomura also says you get to fight with him in your party v Hades.

the Unknowns are officially collectively called The Organization

you Start out in Hollow Bastion (first Playable world) and the idea is that the Heartless are spawning out from HB into other worlds, and Sora and Co. Go there to stop it. it is also referred to vaguely as the "door to other worlds" so that may be the key to getting to the other three dimensions.

Lastly, Realtime refers to IN GAME TIME, not actuall time. it'll be a lot like GTA: Vice City, in that it goes through the cycle of time (sunrise, day, sunset, night, repeat) but at a much faster pace. again, from Nomura.
