Vormir is a remote and barren world and the whereabouts of the Soul Stone in Avengers: Infinity War. Its only known inhabitant is the Stonekeeper. The Stonekeeper guides the ones who come searching for the Soul Stone, but warns them that the price to obtain the stone is very high: the life of a loved person, a soul in exchange for a soul.
It is then visited by Hawkeye and Black Widow in Avengers: Endgame, when they time travel to get the Infinity Stones from 2014. At Vormir, the two of them fight over who has to be sacrificed for the Soul Stone, and in the Black Widow sacrifices herself so Haweye can obtain the stone. Afterwards, Captain America time travels to return the Soul Stone to Vormir.
- Vormir is one of the only planets visited in the Marvel Cinematic Universe that has never been seen as a sphere from outer space.
