Celessa Thul was one of the first of a new breed of Sith. Recruited from the population within the Sith Enclave, she joined the first Sith recruiter to arrive on Mogoshyn. Recognized as strong in the Force, she was transferred to the facilities on Lorn to be trained as a Sith. She was among the first to be recruited into the Sith Revilers, and commanded a unit of them on Runnel for a time.
