Description from Star Wars databank:
SAVAGE OPRESS
Savage Opress was once a common Nightbrother whose fighting prowess impressed Asajj Ventress. Transformed into a monstrous warrior by Mother Talzin, Opress became Count Dooku's new assassin and secret Sith apprentice. His loyalty, however, remained to Talzin. The Nightsisters leader gave Savage a new quest: to find his brother, Darth Maul, who had somehow survived his apparent death and was living in exile in the Outer Rim. Savage located Maul and became his brother's enforcer in the Shadow Collective, but died when Darth Sidious confronted the two Sith warriors on Mandalore.
