Lieutenant Monadno was a military officer as part of the Human Empire. He worked with Captain Shannon in order to investigate the land of Elbyon. There, he and his Captain learnt about the Shadow Isles and about Merlin's Helm and decided to take it. Monadno waited on the stairway leading up to the top platform of the island, but was killed by an arrow from Alammar of Silverwood. (The Sorcerer's Apprentice)
