General Radahn

General Radahn was a demigod and one of the last ones that warred with the rest. He and Malenia the Severed fought a great battle in the Caelid Wilds, but neither won.

Background
During their great battle, Malenia infected Radahn with her scarlet rot. The rot consumed Radahn from the inside, ate away his wits and cursed him to roam as a mindless beast who devoured the flesh of friend and foe alike.
