The Legend of Zelda: The Wind Waker/Forsaken Fortress

The Forsaken Fortress is located in the Northwest 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 cannons and searchlights, and hordes of Miniblins, as well as quite a few Moblins, patrol the place. The Helmaroc King has made his home on the Forsaken Fortress as Ganondorf's servant. It is also the place where Link's sister, Aryll, is held prisoner, along with Mila and Maggie.
