History
Eitri is a Dwarf blacksmith, who forged Mjolnir with his brother Brokk.[1] When the Maker settled on Earth-6160 to reshape it to his image, he facilitated the ascension of Loki to the throne of Asgard, killing Odin.[2][3] Loki enslaved the Dwarves of Nidavellir, turning them into factory workers. Years later, after Thor was released and started the Asgard Rebellion against Loki, Eitri and Brokk were found by him and Sif, making a pair of special cloaks for them, capable of hiding them even from All-Seeing eyes.[1]
