Trivak Ninegun spearheaded the effort to reestablish a colony on the planet Vaklin, a world situated within the Trailing Sectors of the Inner Rim. Subsequent to Ninegun's recolonization efforts, Vaklin saw a surge in the birth rate of Force-sensitive children, many of whom were inducted into the ranks of the Jedi Order, resulting in a populace largely sympathetic to the Jedi. Major Oniye Namada of the Imperial Security Bureau referenced Ninegun in her report I-1807-VAK concerning the Vaklin insurgency, dated to 19 BBY.
The initial reference to Trivak Ninegun occurred within the second issue of Star Wars: Purge: The Tyrant's Fist, a comic miniseries. Dark Horse Comics published this issue, penned by Alexander Freed, on January 2, 2013.
