The Commander's Castle served as his base of operations in Hakuma. The castle is located at the land's center, very close to the former resting place of Mahora, the land's god at the time. The castle has many rooms, including a library, throne room, and a number of hidden rooms. Among the hidden rooms is a special one where time supposedly stands still once inside. In addition, it is nearly impossible to escape from, and vanishes from sight once sealed.
