Doctor Scamandros is a Denizen in The House and Wednesday's Dusk. A self- admitted failed House Sorceror, he is the only sorceror in the allegiance of Arthur . He has assisted Arthur on many ocassions. He was killed when a wave of nothing destroyed the Elysium. However, the New Architect plans to recreate him to help rebuild the house.

He has a collection of colourful, animated tattoos on his face which animate his feelings, a good way of finding out what he really feels. At the end of Lord Sunday, his tattoos disappear.
