Mistress Medusa
From Grigbertz
Mistress Medusa is a dominatrix and sorceress. She is a striking black woman in her forties. Her distinctive snakelike braids and her frightening stare earned her the nickname "Medusa". She is reputed to have left one of the larger corporations after a conflict of interest.
Medusa wants to increase her arcane powers, but she no longer has corporate backing. She decided to gather a group of talented women, and thus be able to induldge in her two favorite activities: lesbian domination and the pursuit of arcane power.
She founded the Dominatrix Coven on Level51 and gathered a group of talented women with similar interests. Few if any know sorcery, but they can contribute Magic Points in the coven rituals. The general nature of these rituals should be obvious given the Mistress Medusa's preferences.
