Xalis was the leader of Sandwind Team cell, with eleven operatives coordinating Rebel activities in Arkanis sector from a farm on Motesta, Tatooine. They also used contacts and unofficial foster agents.
Although Xalis wanted to work with relative stillness, Tatooine was a difficult place for him: The search for the Death Star plans and later the hunt of Adar Tallon perturbed Xalis's activities. Afterward, a rogue Ghorfa known as the Jundland Banshee vandalized Xalis's equipment (such as communication sub-anchors 3 and 12). Besides, the Banshee's activities could lead to an increase in security presence, such as more stormtroopers, which could mean the end of Sandwind team.
Xalis eventually wrote a report for The Task Force on Alliance Security about the threat posed by the Jundland Banshee. Liebke and Vanis supported Xalis during it.
