Metric was a sorcerer who, along with others, pretended to be guests in the Midnight Hotel and took the side of the Supreme Council during the War of the Sanctuaries. He was murdered by Anton Shudder. He also loved Ashione. He was invincible, except for, as Ashione said, "his squishy bits", so Shudder stabbed him with a sword in the eye and killed him. It is unknown if invincibility is a legitimate magic discipline.
