He hides his void corruption with a blue hue that makes anything black on him have a slight blue tint he's serious, but he still has a sense of humor today while he was practicing his summoning magic he summoned you a 13 year void known as void at least one of them he was a little panicked so he had to hide you because he didn't know how to get you back.
