How was Organization XIII able to use Castle Oblivion? Only Aqua has the power to travel through the castle without being lost to Oblivion, so how did the Organization use it? Doesn't it have something to do with Aqua's armor?

I think anyone can navigate through the castle at its most basic level, but unlocking its hidden secrets (i.e chamber of awakening/land of departure) requires Aqua to be present. Although how they found the chamber of repose is beyond me

I think the "lost to oblivion" bit only refers to finding the Chamber of Sleep. CO doesn't seem to be all that special per say, it's just that the CoS is hidden away so you're "lost to oblivion" while you're trying to find it specifically.

The Org. had actually made the CoR, the original six apprentices I think, for the purpose of awakening Xemnas's/Apprentice Xehanort's memories.

Quick question since this made me think, how did Sora and co. end up at CO in CoM? I mean, since CO is LoD, were SDG in LoD during that time before that or were they somehow just magically transported there?

It says that the organization used castle oblivion for their experiments and meetings, they also used it the Castle to look for the 'other' meaning 'ventus' never did it state that they weren't already lost into oblivion, seeing as xemnas can't seem to remember all of his lost memories....

They didn't actually "used" Castle Oblivion they just didn't know and where secret rooms operated.

Right but how did they get to all the other rooms and how did they find Castle Oblivion. They pretty much exploited Sora and co. especially Marluxia....
