Kargalgan was a High Orc Shaman and the leader of the High Orcs. He was the boss of the Hunters Guild Dungeon, an A-Rank Dungeon, that the Hunters Guild B Team raided while Jin-Woo acted as a porter. Kargalgan was a mighty mage that had a very wide variety of spells, having the means to cast both offensive and defensive spells. He could also 'chain' his abilities together as buffs to make him even stronger. Kargalgan wore a cloak as well as bone accessories like bone masks, amulets, and a bone pauldron. He also wore some bandages on his feet and had lines of neon green streaked throughout his body. He was very prideful and liked to entertain himself.
