Glaicus was Lord Arnise's bodyguard, and can be found on the second floor of De'Arnise Keep. He was charmed into serving the invaders of the keep. Once found, he will proclaim his loyalty to his new master and attack the party. He then can be charmed (with any charm spell or the Ring of Human Influence) or dispelled (with a Dispel Magic spell) and talked to for extra quest experience.
