The caged place where you actually start the game is also part of the school.
Little is known about the school. Even its mascot is a bit obscure. At one point, there's a banner claiming that it's the "home of the Vikings"; at another, that it might be the "Western Windknights".
It seems as though it's been long-abandoned. Decay has well set in. Plants have begun to grow within its walls, like a very large tree you encounter early on.
