Medusa who was cursed by a blood red coin
Wears a blood red coin around her neck. Lives in ruined city of Coromagus, left over from a previously unknown civilization. Explored by the Elf Lady Maradel who sought its alien knowledge and discovered something that cursed her (blood coin), turning her into Magora, the medusa.
The heroes defeated Magora by reflecting her image with a mirror they found in the ruined city. She turned to stone, then cracked and fell apart into Lady Maradel.
