Gorgon - Medusas

The gorgons of Ravnica are a monstrous race of creatures that appear superficially similar to human women. In place of hair, a gorgon has a writhing mass of black, serpentine cables, and its hands are scaly claws.
The gaze of a gorgon's glowing eyes causes living tissue to petrify. The transformation is rapid, leaving the victim as a stone statue, usually frozen in a position of abject fear or agony — a fine trophy for the gorgon's macabre collection. The gorgon must exert its will to effect this transformation, so the gaze of a surprised or friendly Ravnican gorgon is harmless.
This deadly gaze attack gives gorgons a degree of power among the Golgari that is out of proportion with their small numbers. Gorgons command a significant share of the guild’s smaller cells around Ravnica. Gorgons of the Golgari are also learned in the ways of magic, and can be fearsome spell casters.
