Another huge collaboration between Star Wars and Fortnite officially goes live on May 3. But after the special event ends, the new Star Wars island that players can visit in their LEGO Fortnite world won’t be going anywhere.

Once the event is live, LEGO Fortnite players will bear witness to the arrival of both the Empire and the Rebellion, with the former crash-landing a massive Star Destroyer upon their arrival. As part of the event, players will get to explore the Imperial crash site and a nearby Rebel village, which can be built up and upgraded over time by completing objectives and building structures.
