Sebastien was the leader of the Red Cloaks for a time until Kasai Masato became the Slayer of the organization. He was known as one of the original founders of the Red Cloaks and also led them through the First Great Magic War.
Not much is known about Sebastien's appearance except that he always covered his face with a mask. It was once briefly seen by the Legendary Six and he was revealed to be a rather handsome man with a glowing purple eye. His choice of garments were usually simple, but he always wore a long blue trenchcoat draped on his shoulders.
Powers and Abilities
Sebastien was rarely seen in the front lines and was usually reserved in the rear to command his forces; however, as the Red Cloaks were an organization where the rankings were determined by strength, it can be assumed that Sebastien was an extremely powerful Mage.
