Zarin was a Tok'ra operative who worked undercover as an underling of the Goa'uld System Lord Ba'al. When The Trust began using a symbiote poison to wipe out the Goa'uld, Teal'c and Rak'nor allowed themselves to be captured and taken to her base on the planet P3S-114, since she was the only Tok'ra they could meet on short notice to question. Zarin dismissed her Jaffa, saying she wanted to have the pleasure of torturing the resistance leaders on her own. Once alone, she berated the pair for compromising her cover and for putting themselves in danger. She was killed along with all Rak'nor and all Jaffa when the planet fell victim to the poison. Her death convinced Teal'c that the Tok'ra couldn't possibly be behind the poison. (SG1: "Endgame")
