Kilgern was Kane's agent and the boss that you have to pass through after passing Islet's Underground Cave. He carries a two-handed sword and is classified a barbarian. After his battle, he attempts to kill Lucio but he was healed by Ameli. After Lucio healed, Kilgren tries to kill Ameli but she was saved by Kuntu. He was knocked unconscious and Kuntu was begged by Ameli to spare his life but he petrifies Ameli into stone with his spell and Kuntu finished him off and this caused Lucio to get help Mage Karan to get a anti-petrifaction spell.
He appears at Mount Olympus as Kilgorn.
