Radiant Garden
Hollow Bastion is dominated by a castle which, now derelict, once was the world's seat of power. Underneath the castle entrance are the Waterways which provide plumbing throughout the castle. A library is here, containing knowledge collected by its former scientists. Aside from the castle itself, there is a town at its foot which is the base of operations for the Hollow Bastion Restoration Committee. A previously unknown entrance here leads to Ansem's Study and his computer room.
Hollow Bastion was once a peaceful kingdom called the Radiant Garden, ruled by Ansem the Wise. In his thirst for knowledge, he began studying the darkness in people's hearts, with six apprentices, including Xehanort. Ansem grew wary of the experiments and stopped them. Unknown to him, his apprentices continued his work, producing the Heartless from hearts that were overwhelmed by darkness. A chain of events led to Ansem the Wise being banished, Xehanort splitting into two beings, and the world overwhelmed by darkness. Empty, the castle was later adopted by Maleficent as a headquarters.
