Ghoel was a Wol Cabasshite from Wol Cabassh. He got his degree at the Prefsbelt Psychiatric Academy before landing a position as one of the General Therapists at Jabba's Palace/Rehab Clinic. He often worked in tandem with Dave Texas. He was appalled when he came to the Palace and found Umpass-Stay serving at the Negative Association Therapist, beating recovering addicts as they looked at pictures of Spice and other substances. He was successful in convincing Jabba to give Stay another position in the Palace.
Rayc Ryjerd was one of his patients.
