Seven-Star Isles

Seven-Star Isles is an archipelago located in the northeastern region of the Great Sea, north of Dragon Roost Island. When looking from above, this island chain resembles the Big Dipper region of the popular constellation Ursa Major.

Features
Of the three island chains in The Wind Waker, the Seven-Star Isles carries the most weight in terms of treasure and plot significance in comparison to the other two. Near the isles, a Big Octo is hidden underwater, which, upon defeat, will leave a Heart Piece behind. Another Triforce Shard is found at the bottom of the sea in close proximity to the island after using the Triforce Chart obtained in Stone Watcher Island to locate it. Link can also retrieve Treasure Chart #16 in this isle by destroying all the rock-mounted cannons positioned strategically amongst the isle's rock spires. This is the only archipelago in the game that isn't visited by the Ghost Ship.

Trivia

 * In the European version of The Wind Waker, the archipelago is named after Ursa Major.
