Kayo

Kayo is a character who appears in Phantom Hourglass. He lived on the Isle of Ember in one of the three house found on the island, excluding the Temple of Fire.

Biography
Kayo was once the assistant of the fortune-teller Astrid. He was the only one who knew how to open Astrid's back room in her basement. Link finds a book in his house, which reads, "If you're reading my words, I have fallen to fate. Look to the east to pick up my torch." After Link finds the remains of Kayo on the most easterly point of the island, his ghost appears, and informs Link how to open the room. He is an inhabitant of the Isle of Ember, and the cause of his death is unknown, though his own words seem to imply that the Ghost Ship's visit to the island played a part in it. Later in the game, upon returning to the island, Link finds Kayo has been properly buried. His spirit stays on the island however, and helps Link find a treasure map, as well as requests that the hero continue to look after Astrid for him.
