Question regarding the possible participants for the 13 and the 7, as someone who follows the lore but hasn't played any of the games so I might be fuzzy on the details:
Isn't aqua the only one who knows where within castle oblivion Ventus resides? A lot of debate seems to be whether aqua will be a light or a darkness, but if Ventus is definitely going to be a light, then wouldn't aqua have had to lead Sora to Ventus to get his heart back to him (since last I checked Sora still has ventus's heart), for him to participate in the war? Which would put her in the light column? I believe xemnas has been questioning Aqua's armor in the castle and trying to find Ven himself, but I am unfamiliar with how successful he's been with that. Maybe it's possible xemnas finds him with aqua's help but the lights somehow end up with him anyway? ---
