Salen Toth was a Jedi around the time of the war between the Jedi Knights and the Sith Brotherhood of Darkness. Salen was sent to the planet Harpori in the Balowa system to investigate the mysterious disappearance of Jedi Knight Crian Maru and her apprentice, Dree Vandap. Salen knew that the two Jedi were on the trail of the Dark Sider Kaox Krul, known as the Marauder, the Madman, and the Dark Killer.
Using the Force as a guide, Salen was drawn to a lake in the middle of the forests of Harpori. There, Salen found the slain body of Crian's apprentice, killed by a lightsaber strike. On the shore of the lake, Salen could find no sign of Dree's master; however, he did note that a darkness permeated the area. Figuring that there was nothing more he could learn of the events that took place, Salen gathered up Dree's lifeless body and returned to his ship, his investigation completed.
