Brokkr and Eitri are two dwarf brothers who dwell in the vast network of caves and tunnels under the Svedanistedi Mountains in Svartalfheimr. They are famous blacksmiths who created three precious objects for the Aesir:
Gullinbursti, the magical golden boar that shines so bright that it turns night into day wherever it travels.
Draupnir, the enchanted golden ring with the ability to multiply itself.
Mjolnir, the renowned hammer of Thor.
The dwarven brothers spend their days tinkering and crafting in their Forge, deep under the mountain.
Surtr of Muspelheim convinced the dwarf brothers to make him a weapon to rival those gifts they’ve made for the gods.
