Outset Island

Outset Island is at the very south of the Great Sea. It is home to only a few families, including Link, his sister Aryll, and their beloved Grandma. On this island, it is customary to garb boys in green when they reach the age of the legendary hero. True to custom, such was done on Link's birthday.

Outset Island consists of two main islands connected by a wooden bridge. Of the four houses on Outset, three of them are situated on the west island. The east island has a winding pathway to the summit of the island. Here, there is a suspension bridge across back the west island and its summit. On the summit of the western island is the Forest of Fairies, where Link rescues Tetra in the beginning of the game. Later, the water spirit Jabun makes his home in the cave at the back of the island. Link is unable to enter Jabun's Cavern until he is able to bypass the large stone guarding the entrance by shooting bombs from a cannon mounted on his ship.

Trivia
