About Mjolnir
Mjolnir is a powerful enchanted war-hammer forged by the Dwarves for the Asgardian Royal Family, and was used by Odin before he passed it down to Hela and then Thor. The hammer was used extensively by Thor as his primary weapon until it was destroyed by Hela in 2017. The broken pieces were eventually made into a tourist attraction in New Asgard.
