Marin was a female Olesian.
In 2005, during the Lt. Colonel John Sheppard's team's visit to the planet, Olesia, Marin greeted the team and sent a security detachment as soon as their presence was detected on the island penal colony. Later, the Magistrate said she was a traitor but that was untrue and just a way to increase the population on the island. It is unknown what happened to her. (SGA: "Condemned")
