Xander, a stormtrooper of the human species, served within the ranks of the 501st Legion. This legion was the personal unit of Darth Vader, the Sith Lord. This particular trooper was a member of a fireteam that included fellow stormtroopers Ella, Riccarn, Tig, and Deena Lorn. After successfully completing several operations as a cohesive unit, the fireteam's members received an assignment to a squad stationed on the Executor-class Star Dreadnought known as the Executor.
While stationed on the Super Star Destroyer, Xander engaged in the illicit production of alcohol by distilling it from the reactor's coolant. The stormtrooper, along with their squadmates (with the exception of trooper FS-451), would often gather in a corner of the destroyer's mess hall, where they would partake in the homemade beverage and ponder the reasons behind FS-451's continued status as a mere stormtrooper. In 3 ABY, when the Executor journeyed to Cloud City, a mining colony on tibanna, Xander, Ella, and Riccarn remained on board the vessel, while Lorn, Tig, and FS-451 were dispatched to the city alongside Vader.
The character of Xander received a mention in "The Witness," a short story authored by Adam Christopher. This story was included in the 2020 anthology of short fiction titled From a Certain Point of View: The Empire Strikes Back.
