Starscourge Radahn "Hoshi Kudaki no Radahn"

About

Radahn was the son of Queen Rennala and Radagon, and mightiest of the demigods. So great were Radahn's powers that he commanded the very stars and held them in place with his powers over gravity, earning the moniker of 'Starscourge'. Those sworn to his lordship carried with them a distinctively red insignia, and Redmane Castle was his personal fortress from which he oversaw his domain within the wilds of Caelid.
