Radagon

He is from the game Elden Ring. While married to Marika, the Goddess of the Greater Will, Radagon studied incantations and was associated with Golden Order Fundamentalism. His son Miquella followed in his footsteps, creating incantations for his father. However, Miquella abandoned Fundamentalism after Malenia's Rot. Marika shattered the Elden Ring, breaking the Golden Order. Radagon remained loyal to the Order and attempted to repair it, but was imprisoned inside the Erdtree.
