A common type M red dwarf, with a total luminosity less than 3% of Sol of Old Terra, with less than 1% in the human visible range.
This star sits in neutral Unknown between Alliance Space and Instrumentality Space, and hosts the homeworld of the Circean Witches.
Circe, the smaller of the two terrestrial worlds orbiting Herak, is controlled by the Circean Witches (The Sisterhood of Circe).
The Sisterhood actively limits the technology on the larger planet, Perseis through its "advisory" role to the world's various governments.
Women on Perseis are tested in adolescence, and those with the talent are taken away to Circe and become novices in the Sisterhood.
