Tren was a middle–aged citizen of the city of Domaz on the planet Kolatill in the Kathol sector. In 8 ABY, Domaz was attacked by TIE bombers deployed from the Imperial Ton-Falk-class escort carrier Kathol Protector in retaliation for the population's overthrow of their Imperial governor following the New Republic's successful liberation of the sector capital, Kal'Shebbol. In the wake of the bombing, Tren organized the food distribution efforts in the city and requested assistance from the crew of the FarStar—a New Republic vessel that had answered a distress call from the planet—in delivering food to neighborhoods on the outskirts of the city.
