Centuries ago, Gunmar betrayed his former leader, Orlagk the Oppressor, for control over the Gumm-Gumms and his Decimaar Blade. The battle lasted many days, until Gunmar finally triumphed over the former warlord by decapitating his head, while in the process, Gunmar lost his right eye.
In "Something Rotten This Way Comes", Strickler gave Jim the eye after keeping his end of the bargain by protecting Strickler. Jim would later cleave the eye, place it into his amulet, and unlock the Eclipse Armor with the other Triumbric Stones, as well as his helmet.
