Sybil

Queen Sybil, known as the Worm Queen, was a female being of an insectoid species who had power in New Xaxxis, the capital city of the planet Metagos. She was the mother to hundreds of children, who served her in her criminal activities. Sybil was rivaled for power in New Xaxxis by the gangster Chulok. In a message delivered to Jedi Master Mace Windu after his death, Master Qui-Gon Jinn posed his fellow Jedi with a mission to the planet that involved breaking the power of Sybil.
