Location from Kingdom Hearts by Tetsuya Nomura / Square Enix & Disney
Yen Sid's enchanted tower at the edge of twilight — a repository of arcane knowledge and the staging ground for the heroes' most critical missions.
The Mysterious Tower is the war room of the forces of light. From this enchanted spire, Yen Sid monitors the state of all worlds, receives intelligence from his communion with the stars, and dispatches his allies to where they are most needed. It is accessible by a magical train from Twilight Town — a journey that carries travelers between the mundane and the magical. This is where Sora, Donald, and Goofy receive their briefings about Organization XIII, where Flora, Fauna, and Merryweather enchant Sora's new clothing, and where Riku and Sora take the Mark of Mastery exam. Despite the tower's modest size, it serves as perhaps the most strategically important location in the forces of light's operations.
A tall, crooked wizard's tower rising from a small island of green hills, with a starfield sky and a crescent moon. The tower twists upward with pointed rooftops in shades of blue and purple. Inside, a winding staircase leads to Yen Sid's study — a round room filled with books, star charts, and a large desk where the sorcerer receives visitors.
