The Kalstan criminal organization operated from their base of operations within the Xorao system.
During the year 1 ABY, Lieutenant Commander Anson Blazer of the Rebellion was conducting an investigation into the gang's illicit operations. Kiran Tatch, a Tunroth bounty hunter present in the system, informed the criminals of Blazer's presence. The gangsters then successfully drove away the Rebel forces, compelling them to abandon a significant quantity of valuable supplies.
