Fortnite's story revolves around the Zero Point, a nexus of all realities, controlled by the Imagined Order (IO), who use it to create the Battle Royale island loop for Loopers (players). Major factions like The Seven, The Last Reality (aliens), and shadowy figures clash, constantly shifting the island's reality through cataclysmic events (meteors, black holes, cube invasions, chrome corruption), culminating in grand live events that reset or transform the map, leading to new chapters and eras like the Zero War, Fading Stars, and recent Big Bang era, all while the Seven try to free reality from the IO's control.
