Iguvuarge is the leader of the adventurer group Kralgra. His dream is to become a hero which saved the world, just like the Thirteen Heroes of the past. He subjugated everything to this dream, going as far as spreading false rumors about him or using his companions as meat shield, all stepping stones for him to reach the peak. Yet, he was hardworking and trained intensely which made him intensely dislike Momon who seemingly appeared from nowhere and caught up to his mythril rank in a single adventure. Summoned to a meeting with all the mythril-ranked adventurer teams of E-Rantel to discuss the appearance of the powerful vampire Honyopenyoko, he tried to provoke Momon, questioning his ability as a mythril adventurer. Engulfed by his own pride and resentment toward Momon, he chose to accompany him against the vampire, despite Momon's warning. Once in the forest, Albedo started to kill the members of his team and he fled, only to lose himself in the forest due to Mare's spells. Mare then immobilized him and killed him by crushing his skull with his staff. (Source: Overlord Wikia)
