Marhys Wyllyms was an Emeraldian agent who worked as the majordomo of Kahlvyn Ahrmahk, Duke of Tirian.

He was placed in Charis as a long-term agent. At the end of the Year of God 890, he had been the Duke's majordomo for almost sixteen years. When Earl Gray Harbor and Merlin Athrawes exposed and killed Tirian, Wyllyms fled from the Duke's town house, killed Braidee Lahang in order to keep him from being caught and interrogated, and afterwards returned to Emerald.

Once back in his home country, he gave a full report of his activities and his knowledge of Merlin's extraordinary capabilities to Prince Nahrmahn and Lord Shandyr. (OAR)
