The Dothraki are the horse-riding warriors of Game of Thrones, and dragons are the signature creatures of Daenerys Targaryen's storyline, which is why this pairing is instantly recognisable to fantasy fans. Short clips like this one are commonly lifted from battle scenes and shared on soundboards, where they live on long after the show itself. Editors keep returning to it because a dragon attack needs no explanation: the roar alone signals overwhelming power, turning point and spectacle in a few seconds.
