Drey'auc was from the the Cord'ai Plains on the planet Chulak. Like most Jaffa, she was loyal to the Goa'uld. After Teal'c revealed to her his mentor Bra'tac's doubt of the Goa'uld godhood, she urged her husband to tell Apophis of this. This loyalty continued even after her husband betrayed the Goa'uld, joining the Tau'ri, She worked diligently to restore Apophis' faith in her and her son so the Prim'ta ritual could be performed when Rya'c came of age. When Teal'c returned and stopped the ceremony, she informed him that Rya'c will die without a symbiote. He gave him his own and later replaced his with the one Captain Samantha Carter and Dr. Daniel Jackson stole. Drey'auc remained on Chulak under the care of Bra'tac. (SG1: "Bloodlines", "Threshold")
