The Night's Watch is the ancient order that guards the Wall in Game of Thrones, the HBO fantasy series based on George R. R. Martin's novels that first aired in 2011. Their oath and grim sense of duty became shorthand for loyalty and sacrifice among fans, and short clips from the series circulated widely in edits, reaction videos and memes long after the show ended in 2019. The sound still works because that world remains widely recognised, and a few solemn seconds can give a modern edit an instant sense of scale and foreboding.
