Fafnir

Description

Son of Hreidmar and brother of Óter and Regin. It is unknown what gave him the possibility of transforming into a dragon, but he achieved it in the most absolute greed because of the curse of the Ring of Andvari. He was finally executed in combat by Sigurd, and the Ring of Andvari, along with the gold it generated, was lost at the bottom of the Rhine River.
