Ansem's study was the private study of Ansem the Wise in Hollow Bastion. The room contained a throne and desk, containers filled with hearts, and books. As leader of Radiant Garden, he used it to store his research on the heart. There was a secret passage in the wall to Ansem's computer in the study. King Mickey and Ansem often talked in there. There was a portrait of Xehanort in the study, though it is unknown if Ansem or Xehanort put the picture up there.
