Gale Isle
From The Wind Waker Randomizer
Gale Isle is located at D1. It has a dungeon and a sunken treasure.
Dungeon
(Main article: Wind Temple)
Gale Island contains the entrance to the Wind Temple. This entrance can be accessed by using the Iron Boots to walk through the gusts of wind and the Skull Hammer to destroy the stone creating the gusts. In the vanilla game, the player will receive the Wind God's Aria outside the entrance to the dungeon, but the stone is removed in the randomized version of the game.
Sunken Treasure
The sunken treasure in this quadrant can be accessed by opening Triforce Chart 2 when charts are not randomized. This chest contains a Triforce Piece in the vanilla game.
