When the Mask of Eternity shattered, Spriggans invaded Daventry. The Spriggan Leader led the assault, placing himself in a position of command atop the old Castlekeep Ruins of Daventry. It was here that Connor found him, and slew him. Connor took the monster's Leather Breastplate for himself.
The Spriggan Leader appeared in King's Quest: Mask of Eternity.
