Trea Kobbeth was a Pilgrim of the Twi'lek species, and a female, who resided illegally on Tython during the Cold War period. This era was defined by tensions between the Galactic Republic and the reconstituted Sith Empire.
Trea Kobbeth, a female Twi'lek, journeyed to Tython with her son, Viyo, as part of the Pilgrims following Matriarch Kolovish. This migration occurred after the Great Galactic War and the Hutt Cartels' enslavement of Ryloth. When her son vanished, abducted by a Flesh Raider in the area of Tythos Ridge, Kobbeth, who had assisted in establishing Kalikori village, was distraught. She pleaded with a young Padawan visiting the village to locate him. Viyo was soon found unharmed, as the Flesh Raider only desired him for his translation skills.
She was married to a man named Kobbeth, who served as a sergeant within the Republic Military. On Belsavis, this Twi'lek man encountered an Imperial who rescued him and a squadmate from an Esh-kha attack in return for a vault key.
