In Norse mythology, Geirrod was a giant who lived in an iron castle. He was determined to punish Thor for killing Hrungnir, and to this end he captured Loki and tortured him until he agreed to trick Thor into visiting Geirrod's castle. Loki managed to geThor out of Asgard without his belt of strength, iron gloves and hammer, but on the way to Geirrod's castleThor met and mated with the sorceress Grid who subsequently gave him another belt of strength, a pair of gloves and an unbreakable staff. Geirrod tried several attempts to kill Thor, until finally throwing a lump of red-hot iron at him at breakfast, which Thor caught in his gloves, and hurled back, the red-hot iron searing through the guts of Geirrod and killing him. This incident caused Thor never again to trust his former friend Loki, and is one aspect of the anatgonism between the gods which will one day culminate in the cosmic battle which will end the current cycle of the universe.
