The private library of Darth Thanaton was a large underground area where Thanaton kept many holocrons and relics. Notable out of all the writings and artifacts were the writings of Darth Vilus and Darth Iratus. Lord Kallig, later Darth Nox, visited the library to find a way to cure the Force walk sickness. When Thanaton was killed during the duel between the two Sith, Kallig became the library's owner.
