The tower housed Darth Krayt's throne room, and was formerly used to house the Council of First Knowledge. When Darth Krayt removed the Temple Pyramids, he exposed the Tower of First Knowledge. Removing all vestiges of its Jedi past, he transformed the Tower into his personal area of the Temple. Beneath the throne room was the Embrace of Pain chamber where Cade Skywalker would be tortured in the Embrace.
