Star Isles

The Star Isles are close-kint archipelagos found in three regions of the Great Sea, all of which exist as constellation-resembling rock formations. These archipelagos are among the smallest and least populated bodies of land in The Wind Waker, but often have much to offer in terms of Ghost Ship sightings and Treasure Chart plunder, such perks that function as the isles' primary, if not only, attractions.

Five-Star Isles
Five-Star Isles is located in the southeastern corner of the Great Sea, that is made up of thin rock spires in the shape of the Cassiopeia constellation. Even though Link cannot physically traverse the "isles" themselves (unlike the Kargaroc birds), several perks in the surrounding area make the visit to his island chain worthwhile. First, a Piece of Heart can be retrieved by entering a submarine nearby, and erradicating all the enemies within. Link can locate and obtain a second Piece of Heart by sailing to the marker set near this island chain by Treasure Chart #33, the chart of which is found in Windfall Island.

This island is also a recurring destination of the Ghost Ship, seen only the night when the moon is at its waxing crescent phase: simply when the moon is ")"-shaped in the night sky.

Star Belt Archipelago
The Star Belt Archipelago, located in the northeastern region of the Great Sea, southeast of Dragon Roost Island, is made up of a group of rocks sticking out of the water in the formation of the Orion constellation. When the moon is in its first quarter stage (half-full with the left side in darkness) in the night sky, the Ghost Ship will appear in these waters.

Seven-Star Isles
Seven-Star Isles is 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.

Of the three island chains in The Wind Waker, the Seven-Star Isles carries the most weight in terms of treasure and 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.
