Where was the great Sith Sorcerer Naga Sadow buried?
In KotOR, Revan visits his tomb on Korriban to retrieve his special weapon (the Poison Sword, I believe) but I don't recall if his body or casket is ever shown. Three centuries later, The Emperor's Wrath desecrates the tomb by order of Darth Baras and retrieves Sadow's ancient lightsaber. During the cut scene, the Wrath moves the lid on the casket and there's a skeleton in there complete with Sadow's traditional headdress. He reaches inside and grabs the lightsaber lying next to the body.
However, according the Golden Age of the Sith comic books and the Time Line videos that were released just before SWTOR, Sadow was exiled to Yavin IV, where he lived to the end of his days. Jedi Ovair and his apprentice Gynt visited the tomb there as well. So where was Naga Sadow really buried and why does he have two tombs?
Were the Sith on Korriban during the Cold War just unaware that Sadow was in exile on Yavin IV?
