The Legend of Zelda: The Wind Waker/Forsaken Fortress

The Forsaken Fortress is located in the northeast of the Great Sea in the Wind Waker, and it's where Ganondorf has made his hideout. It's an evil-looking island, and most people tend to avoid it. The place is well-guarded with canons and searchlights, and hordes of Miniblins, as well as quite a few Moblins, patroll the place. The Helmaroc King has made his home on the Forsaken Fortress, and it is also the place where Link's sister, Aryll, is held prisoner, along with Mila and Maggie.
