Orvak, an officer in the Imperial forces, commanded a TIE Fighter assault from his TIE stealth during the battle of the Jedi Praxeum which occurred on Yavin 4.
Flying alongside his second-in-command, Dareb, Commander Orvak managed to bypass the Jedi Praxeum's protective shield. He then proceeded to destroy the shield generators utilizing thermal detonators. Subsequently, he infiltrated the Great Temple and placed additional detonators. A crystal snake bit him, and he only awoke just before his explosives detonated. The explosion resulted in Orvak's death.
