The Infernal Forge is a location on Muspelheim where Scabrite is produced.
History[]
In an attempt to find Scabrite with which to defeat Mangog, Thor traveled to Muspelheim. He fought his way through many Fire Demons and entered the Infernal Forge, where he discovered the Scabrite-forged Twilight Sword and its owner, Surtur. Seeking revenge for Odin's theft of the Eternal Flame many centuries before, Surtur attacked Thor and the two engaged in an intense battle. Thor defeated Surtur and destroyed his sword, collecting the Scabrite he needed.[1]
