Hythonia the Cruel

Theros's reclusive medusas often delight in collecting and expanding their galleries of Petrified victims. Unlike other medusas, Hythonia isn't merely a collector; she's an artist. When Hythonia came to the island of Skathos, the inhabitants worshiped her as an avatar of the god Pharika. The Cultists eagerly offered themselves up to the medusa's petrifying gaze in hopes of gaining Pharika's favor. Seeing herself surrounded by willing devotees, Hythonia formulated a cruel plan. After encouraging them to engage in wild Rituals, Hythonia began turning her followers to stone, weaving their forms to create a grisly throne made of their Petrified bodies.
While the medusa's victims have dwindled, tales of the Medusa queen and the divine Secrets she hoards have not. Hythonia eagerly trades the Mysteries she knows but demands a constant price: a beautiful individual to become part of her throne.
Hythonia makes her lair on Skathos, an island where a Secret sect of worshipers dedicated to Pharika previously hoarded Secrets and engaged in dark Rituals.
Although Skathos's Location remains a Mystery, stories tell of the island's magical Plants and Hythonia's various Treasures. Hythonia encourages such rumors by letting lone Survivors Escape her realm, letting the ravings of Survivors tempt more playthings into her clutches.
