Eitri

Eitri is a name that appears in Norse mythology and in modern popular culture as a figure associated with dwarven smithing. In the traditional Norse corpus, the exact identity of Eitri varies by source. Some passages describe him as a master dwarf smith, while the more widely told tale centers on the allied dwarven brothers Brokkr and Sindri who, under Loki’s wager and with magical aid, forge legendary treasures such as Mjölnir, Gullinbursti, and Draupnir. Because the surviving texts are fragmentary and differ in detail, interpretations of Eitri’s role differ across editions and translations.

In contemporary Marvel fiction, Eitri is the king of Nidavellir and a master smith renowned for his craftsmanship. He is depicted as a resourceful artisan who creates advanced weapons for the Avengers, most notably Stormbreaker, Thor’s battle axe. In the Marvel Cinematic Universe, Eitri appears in Avengers: Infinity War and is portrayed by Peter Dinklage. During the events at Nidavellir, Thanos attacks the forge, and Eitri sacrifices his life to help complete Stormbreaker, enabling Thor to continue the fight against Thanos.
