Vitiate II

"Power is what drives us, but it is also what kills us"

 was the son of the Sith Emperor Vitiate. Vitiate the second was born right before the outbreak of the Second Great Galactic War, by the Sith Emperor using a recently discovered dark side ritual to create a second body in case his mortal form was killed, however, it entirely replicated his spirit as well, making Vitiate II an actual person, and his "son".
