Immortal Emperor

The Immortal Emperor, despite what his moniker would suggest, was not a "true" immortal, but rather a tenacious spirit who refused to spend an eternity in Chaos for his misdeeds, terrified of true death and the fate that awaited him in the afterlife. The Immortal Emperor liked to inhabit and "hollow out" bodies to use as vessels. His endgame was a ritual that would "devour" the galaxy, allowing him to absorb the souls of all sentient beings within and ascend to Godhood. Effectively, the Immortal Emperor was not a singular entity, but rather an amalgamation of all those he's assimilated. The Voss prophesied his final defeat at the hands of an orphan, so nearing the waning years of the war between the Sith Empire and Galactic Republic, he ordered the assassinations of hundreds of Jedi whose parents were deceased. For over three hundred years, the Immortal Emperor was forcibly confined to the body of an elderly man by the Dark Council, who knew of his true plans. He was unknowingly released from his "prison" by his arch-nemesis Orion Eleos and the man he had been grooming to be his vessel, Danyar Norden. Upon his release, the Immortal Emperor's weakened spirit travelled to Ziost where the returned Darth Revan unknowingly helped restore some of his strength in a misguided attempt to kill him once and for all. The Immortal Emperor's spirit was then able to supercharge itself by devouring the world. The Immortal Emperor then possessed a traveller who made his way to the planet of Zakuul. There, he possessed the world's emperor Valkorion, hollowing him out and taking over his technologically advanced empire, resuming his plans of devouring the galaxy as a whole.
