Schemes of the Lich King
A wizard in league with the Diabolist
Carthus was the leading figure in the takeover of the castle of Princess Argenta in Haven. Unclear whether or not he masterminded the entire affair or if he merely was an opportunist who decided to use his abilities to bring further ruin and evil to the land, he had attempted to gate in a Piscodaemon with the aid of Davon the Reckoner, but was killed by Glaedwin Longcleff before further damage was done. With his death and the subsequent destruction of My Lady’s Heart, the evil magic was lifted from the land. He seemed to be a willing servant of the Diabolist. Whether or not he was actively trying to thwart the discovery of the lost city of Darkveil was never determined.
