Pasir Letin was a Cardassian male and agent of the Obsidian Order. In 2323, Letin infiltrated the followers of the Oralian Way that were being taken to Bajor by Bennek. Upon arrival at Bajor Letin planted a bomb aboard the Way's ship, the Lhemor, which destroyed the ship and Cemba Station. Letin then befriended Bajoran ranjen Gar Osen and one night took him on a flight across Bajor. During the trip, Letin killed Gar and took his place, infiltrating the Bajoran clergy. By 2328, Letin was still serving in the clergy and acting as Gar when he helped Rhan Ico takeover Bajor by slowly destabilizing the planet. He was also responsible for destroying Bennek's Hebitian mask and writing because Bennek tried to ask him, as Gar, for help. (ST - Terok Nor novel: Day of the Vipers)
