Unknown to most the patrons of the Ace of Sabres Cha-Val Sha-Vak was in the employment of Sibarra. He performed the Hutts dirty work such as assassinations, robberies, debt collection and extortion. Any work that Dunan Par'Ell, head of security at the Ace, could not handle was given to Cha-Val Sha-Vak. There was considerable tension between Par'Ell and Cha-Val Sha-Vak.
