Room of Awakening

The Room of Awakening is a mysterious room that Xemnas was looking for in Kingdom Hearts II. It is said to contain his other "friend" who is suspected to be Ven. This room is also said to be found in Castle Oblivion. Whether or not Xemnas ever found this room is unknown and may be touched upon in later games.

It is not known whether this is the room that Riku first found himself in at the beginning of his story in Kingdom Hearts: Chain of Memories.
