Daertha Ollan was a female Twi'lek Jedi who was a member of the New Jedi Order and, later, the Jedi Coalition. Born on Commenor, Daertha was unaware of her Force-sensitivity until her teenaged years. Running away from home, she sought refuge with the New Jedi Order on Yavin 4. There, she was accepted into the order and trained to become a full-fledged Jedi. She quickly rose to the rank of Jedi Knight by aiding the Order defend against Admiral Daala and the Empire Reborn.
