Mauritys Guile is a resident of Meiyerditch and Myreque member referenced in the Darkness of Hallowvale quest. During the quest, a servant in Castle Drakan known as Sarius Guile refers the player to Mauritys' former home, where a message can be found.
Mauritys was forced to work in the blood labs beneath Meiyerditch and narrowly escaped the laboratory's destruction by the vyrewatch. He was later pursued by the vyrewatch, but managed to hide a message within the fireplace of his home. The message is directed at the Myreque, specifically its leader, Safalaan Hallow.
