End Times comes from the soundtrack to Outer Wilds, the 2019 space exploration game by Mobius Digital, with music by Andrew Prahlow. In the game, players explore a small solar system trapped in a repeating 22-minute time loop that ends with the sun going supernova, so the track is tied in players' minds to that quiet, inevitable ending. Fans have since reused it in gameplay edits, video essays and tribute videos, where its calm, reflective tone works as shorthand for the game's themes of curiosity, loss and acceptance.
