A technologically limited world that has yet to unite under a single world government. Technological advancement is crippled due to the secret efforts of Circean Witch advisors to various world governments, in a diliberate effort to prevent the various nations of Perseis from advancing in power and influence. It’s people largely live in primitive, early industrial conditions (something akin to the 19th century of Old Earth in the ancient reckoning)
Women on Perseis are tested in adolescence, and those with the talent are taken away to Circe and become novices in the Sisterhood.
