Rohngall

An agent for the Magic Association sent to investigate the rumor of a Holy Grail War beginning to take place in the city of Snowfield, California. Rohngall is an elderly man with short, white hair, a short white beard and rather prominant eyebrows. He wears a dark robe and a rounded beige cap with a silver band around its hem. At some point in the past, Rohngall took Faldeus Dioland as his student, unaware that the younger man was a spy for the American organization. (Source: Type-Moon Wikia)
