Thork was the Warlord of the Frost Orcs, ruling over them from the Ice Lord's Stronghold. Shortly before the Cataclysm, he entered into the service of Lucreto. Under this alliance, Thork had captured King Gryph during the storm that arose when the Mask of Eternity was shattered and set chaos upon the Frozen Reaches. When Connor began to search for King Gryph, Lucreto commanded Thork to kill Connor.
Instead, Connor managed to infiltrate the citadel and slay Thork.
Thork is a character in King's Quest: Mask of Eternity.
