Yhtac

Yhtac is a beautiful mermaid in Patagonian mythology with a tail covered in golden scales and skin in color of pearls. She was considered the most elusive creatures on earth. A sorcerer named Arasmin was so enamored of her that he flew around the world with his castle in search of her. And when Arasmin finally found her, he transformed himself into a sea creature, so Yhtac, wouldn't have a reason to reject him.
