In a final confrontation, Exitium reveals how Nathema was destroyed and the reason why he launched the invasion on Dromund Kaas. The Emperor forged a mental link to the Dark Hero and he needed the battle to distract him. He also reveals the body he's using is actually the body of a former Dark Council Member. And finally reveals why they are immune to the affects of Nathema. It is from a technique they learned from the Trayus Academy long ago in their previous life where they learned on how to feed on themselves. With all the loose ends answered the battle begins.
