Dengar was a Corellian bounty hunter operating since the early stages of the Clone Wars. Dengar participated in an operation on Quarzite—during which he served as a member of Krayt's Claw, a syndicate of hunters including Boba Fett, Bossk, and Asajj Ventress—to secure property valuable to Lord Otua Blank of the planet Quarzite.
Awesome! I love Dengar.
