Vance Rego was a member of the Cilpari Resistance in 4 ABY. He was supposed to meet Winter—the New Republic case officer for Cilpar—and obtain aid in fighting the Imperials. He was also working for the local Imperial Moff, Boren Tascl, as a double agent. He led Tascl's stormtroopers to Winter's location, then later claimed to resistance leader Elscol Loro that he had barely escaped the trap himself.
