Five-Star Isles

Five-Star Isles is an archipelago located in the southeastern corner of the Great Sea, that is made up of thin rock spires in the shape of the Cassiopeia constellation.

Features
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 eradicating 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 on 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.
