Truya Djo was the daughter of Saria Djo, the leader of the Fire Island clan on Dathomir. Like her mother and sisters, she was strong in the Force—strong enough, and lucky enough, to survive several attacks from the Nightsisters from 4 to 8 ABY. Saria's other daughters died during these attacks, and Truya was the only female of Saria's line to survive.
