The Stasis Room in the XoXaan's Temple on Korriban was used by the One Sith as of 137 ABY. It was here that Darth Wyyrlok brought the body of Dark Lord of the Sith Darth Krayt after his death at the Battle on Had Abbadon. To maintain control of the order, Darth Wyyrlok placed Krayt's body in the Stasis Room so that others would think that Krayt still lived, allowing Wyyrlok to act as Krayt's Voice and Regent while secretly controlling the Empire.
Saarai, and later Darth Talon, were charged by Lord Wyyrlok with the task of guarding the room from unwelcome visitors.
