Darth Vitus was a male individual who became a Sith at some point before the time of the Mandalorian Wars and the Jedi Civil War, at which point he was considered an ancient Sith. After gaining significant knowledge of how to utilize Sith alchemy, he desired to develop his understanding of the subject further, so he carried out research at a compound on the moon Oricon in the Outer Rim Territories. During the course of his investigations, Vitus experimented on monsters that were strong in the dark side of the Force.
