Savax, the War-Master of the Southern Wastes and a member of the Clan-Vorsazg, was the head of a "Ubese" clan. He spearheaded an alliance of legitimate Ubese clans originating from Uba IV in opposition to the "yrak pootzck" Ubese residing on Ubertica.
Driven by feelings of envy and a desire for retribution, Savax initiated his military operation. He believed that the inhabitants of Ubertica were living an opulent lifestyle under the governance of the Republican and subsequently the Imperial regimes. Meanwhile, the Ubese on their ancestral home planet had faced immense hardship and a constant battle for survival ever since the bombardment of the Uba system which occurred over a millennium prior. Savax deemed the obliteration of Ubertica, along with the demise of its entire population, as a crucial step for the "True" Ubese to break free from the burdens of the past and reclaim their rightful position within the galaxy.
During the strike against Ubertica, Savax's military contingent comprised five capital ships, staffed by a unified force representing numerous clans from Uba IV. Speculation suggests that the Hutts provided these vessels. Although his forces effortlessly devastated numerous cities across Ubertica, Imperial forces intervened, resulting in the complete destruction of all five ships. Among the wreckage of his fleet, a datafile authored by Savax was discovered, detailing his justifications for committing acts of genocide.
