"A Transient from the world of Yggdrasil and member of the Otemachi Genociders. In addition to his flaming Sword Sacred Artifact, which can burn the safeguards of worlds to ash, he also wears a black Helmet Sacred Artifact which etches fear into his target. In memory of his perished children, he will never remove the helm. Any who express their flame-like existence are beloved as his children." - Subverted, Surtr’s not evil, so much as he’s duty-bound to those he considered family.
