Omadrians are a canton of women on Mongo who specialize in making powerful medicines. They live in a village in the swamp forests. Omadrian women consider men to be the source of violence and injustice. They "transform" men into peaceful drones, castrating them and removing their aggression. The drones serve quietly, and faithfully. Omadrians are not welcoming of strangers; they lay deadly traps near their village to discourage thieves.
