The most substantial area of the Tomb, a detention center crafted by the Rakata race on the world of Belsavis, was known as the Ancient Rakatan Keep. A gigantic Zedalus Tree was its defining feature, with the Rakata installation the Esh-kha called Cave-Under-Tree situated underneath. This keep, a lush valley warmed by numerous magma fissures, provided access to all the other, less expansive sections of the Tomb.
In the game Star Wars: The Old Republic, the Ancient Rakatan Keep is depicted as a distinct subarea within the Tomb on Belsavis.
