The clip takes its name from Hyrule Castle, the central royal castle in Nintendo's The Legend of Zelda series and a recurring final destination for Link. In recent games the castle is shown as ruined and corrupted, and its underground areas are paired with sparse, ominous music rather than a heroic fanfare. Clips of that music circulate online among Zelda fans for edits, gameplay montages and fantasy memes, where the recognisable location name alone signals danger, lore and an approaching confrontation.
