I am Darth Azalus, I shall destroy the Jedi and I shall serve the Sith
—Darth Azalus after being promoted
Sirak Kolar was a Zabrak Sith who entered the Sith Inquisitors. He was raised as a Sith from birth the same as his siblings, Dishi'ra and Maris on Kroprulu. Sirak learned the art of Teräs Käsi from his father who managed to master it and he himself became excellent in it. He was renamed as Darth Azalus when he was promoted from Sith apprentice. He was very hateful towards Jedi, Mandalorians and slavers based on the what he had heard from his father. He was respectful, and obedient and unlike many of the Sith, he never once thought of betraying anyone.
