Versailles sat up with a satisfied expression on her face. Before her eyes were the stone like statues of three snake haired women, their expressions frozen in shock and disbelief.
This was Versailles' reason for choosing the Poison Fields. The three Gorgons.
During one of her exploration expeditions in her last life, Versailles found in an ancient monument that using the red-green eyes of a python, Gorgons could be turned to stone. If one combined the magical ability of the eye with their own power, they would have the ability to commend the stone turned Gorgons.
This stone transformation was not literally stone, but stone in the sense they would no longer be beings with emotions, feelings, will, or individuality.
