Mysterious Tower

Mysterious Tower is a world in Kingdom Hearts II, Kingdom Hearts Birth by Sleep, and Kingdom Hearts 3D: Dream Drop Distance. It is the home of Master Yen Sid, and serves as a starting point for Sora and Mickey's quests in Kingdom Hearts II and Kingdom Hearts Birth by Sleep, respectively. It is a unique world that doesn't always remain in one place, so although it is considered part of Twilight Town in Kingdom Hearts II, at other times it appears on its own.
