Xim, also known by the moniker Xim the Despot, was a male and ruthless warlord who existed far in advance of both the Galactic Empire's reign and the First Order. During the time of the Empire, a mytag crystal masthead fashioned from Xim's skull was found aboard First Light, the luxurious star yacht belonging to crime lord Dryden Vos. In the decades afterwards, the Supremacy, which served as the First Order's mobile capital and flagship, was reputed to be larger than even the most exaggerated reconstructions of Xim's flagship. Tryphon Leo once desired to possess a fortune equal to Xim's, however he died before he could achieve that ambition. The labor droid Bollux once told Tivoche "Midnight" Bilure, a bartender, that he had aided the rogue Han Solo in the destruction of a battalion of war droids that belonged to Xim. Furthermore, Bollux claimed he was currently seeking out locations and relics related to Xim on behalf of a university located in the Outer Rim Territories, and that his pursuit of a lead regarding a piece of treasure had brought him to Vandor.
The initial mention of Xim the Despot within Star Wars canon occurred in the 2017 reference book titled Star Wars: The Last Jedi: Incredible Cross-Sections, which was authored by Jason Fry. The character of Xim was originally conceived for the Star Wars Legends novel Han Solo and the Lost Legacy, published in 1980 and written by Brian Daley.
