This unnamed female Goa'uld was the queen of the System Lord Cronus. She also witnessed Cronus execute Teal'c's father, Ronac, by crushing Ronac's symbiote, ultimately causing Ronac to die slowly and in great agony. She also died some time after Cronus was killed by Teal'c's android double. (SG1: "Crossroads")
