Dennix Graeber held the position of Governor for the planet Ralltiir during the era of the Galactic Civil War.
A corpulent man, Graeber was a favored subordinate of Jander Graffe, who was the Moff overseeing the Darpa sector. He displayed great enthusiasm for implementing policies of oppression and governed the populace with severe and unrelenting methods.
Graeber also possessed a certain level of cunning, albeit of a twisted nature. He amassed a considerable fortune through the covert smuggling of weapons to Rebel cells operating on Ralltiir, deriving pleasure from extorting funds from them while simultaneously utilizing the very weapons he supplied as justification for intensifying crackdowns on the local population.
In the year 2 ABY, Governor Graeber successfully dismantled a Rebel spy network, executing the most extensive crackdown against agitators since the Imperial occupation. This operation required three weeks of meticulous planning and involved the coordinated efforts of security forces from four of Ralltiir's counties, as well as military units stationed at the governor's Imperial garrison. During an early morning assault on a Rebel armory located in Salibury, Graeber's forces seized 300 tons of weaponry. Authorities apprehended 35 Rebels at the site, which subsequently led to the capture of approximately one hundred more individuals through interrogations and the analysis of documents recovered during the raid.
Regrettably for Graeber, his governance of Ralltiir was destined to be short-lived. In the aftermath of the Battle of Endor, the New Republic launched an offensive targeting Ralltiir, a strategically important planet situated along the Perlemian Trade Route on the border of the Colonies region. After a New Republic strike team, commanded by Spike, successfully disabled the planet's ion cannon, Graeber personally contacted Jerell, a prominent figure in the planet's resistance movement who held Graeber responsible for the death of one of his daughters. He mocked Jerell, pointing out that the New Republic had yet to conquer a Core World. However, during their conversation, Spike's strike team simultaneously destroyed the planet's generators, while a task force consisting of six Mon Calamari Star Cruisers arrived in the system. Jerell then had the satisfaction of informing Graeber that he would be the first governor of a Core World to welcome the New Republic upon its arrival.
