Seldanor

Seldanor is a god from the Vok'thar religion. When the Vok'thar were first discovered, scientists were astonished how they devoted their life to this one God. Due to the scientists' connection to the Jedi, they feared the Dark Side to belong to this God.

It would eventually be revealed by the Hero of Tython that this was a reincarnation of Sel-Makor, wanting revenge against the Jedi Knight that killed it together with the Voss.

The mercenary
When Sal-ker O'finn arrived on Ilum, he visited and threatened the local Vok'thar village. As he forced the village's shaman to reveal the location of the Lost Artifacts, the shaman informed O'finn about the God they believed in and how it would follow him around and how he would end up dieing quickly if had he not entered the sacred burial ground of their God, or so they believed. Not caring about this, O'finn would still enter Seldanor's sacred ground, and obtain what he was looking for.
