It’s not exactly a spoiler that Thor loses his hammer early on in Thor: Ragnarok. Unless you ran from the room every time a trailer for the film started playing (good on you for your commitment to a spoiler-free lifestyle, if that’s you) then you likely saw the Asgardian God of Thunder’s precious bludgeon get cracked to pieces by Cate Blanchett’s Hela. That loss is what defines Thor’s search for meaning and friendship on the trash planet of Sakaar, but that doesn’t mean Mjolnir was forgotten.

Chris Hemsworth uploaded a touching in memoriam video for Mjolnir to his Twitter account today. The video also acts as a promo for Ragnarok, highlighting one of the better scenes in the movie where Thor is explaining to a fellow indentured gladiator how important his hammer was to him.

Created by Stan Lee, Jack Kirby and Joe Sinnott, Mjolnir first appeared in Journey into Mystery #83 in 1962. An adaptation of the Norse god Thor’s iconic hammer, the comic book variation was given a decidedly cosmic Marvel backstory. The hammer is forged from a metal called Uru by Dwarven blacksmiths. In the video, it’s explained that Mjolnir was forged using the heat of a dying star, which is only a mild deviation from the weapon’s comic book origins.

In theaters now, director Taika Waititi’s Thor: Ragnarok stars Chris Hemsworth as Thor, Mark Ruffalo as Hulk, Tessa Thompson as Valkyrie, Tom Hiddleston as Loki, Cate Blanchett as Hela, Jeff Goldblum as The Grandmaster, Idris Elba as Heimdall, Anthony Hopkins as Odin, and Karl Urban as Skurge.
