Darth Tremab De'eva was the third and youngest son of the De'evan, and also the black sheep of the family. He was the first Sith lord in the family's recorded history and he played a significant part in the rise of his nephew, Lord Kaissen De'eva after the De'evan's assassination.  He field-tested HD 001-Prototype and, after being captured by the Jedi, he managed to escape with the aid of a traitor and the manipulations of his nephew.
