The Tomb of Naga Sadow was the final resting place of the Dark Lord of the Sith Naga Sadow. It was located in the Valley of the Dark Lords on Korriban, and was excavated when the Sith Academy was established there during the Jedi Civil War.
In one of the inner chambers of the tomb, where the Dark Lord was buried, his sword rested with him. In another inner chamber there were two ancient pillars, a Pillar of Fire and a Pillar of Ice, each holding a special grenade. The antechamber before this inner room was guarded by two terentatek, however. The third inner chamber was inaccessable due to a river of acid flowing through the middle of the room, unless a particularily strong and clever apprentice was able to find a way around or over it. This last inner chamber held a Star Map and a Sith statue with a Sith Lightsaber, which was the final test of the Sith apprentices before their being officially accepted into the Sith Order.
