Sahasrahla

Sahasrahla (サハスラーラ, Sahasurāra) is an elder of Kakariko Village in A Link to the Past. As the descendant of a Sage, Sahasrahla is gifted mystical abilities, boasting telepathic powers not unlike those of Princess Zelda. Sahasrahla was forced into hiding because of the growing threats of Agahnim. Sahasrahla is said to be a descendant of one of the original Seven Wise Men, or Sages that Agahnim is looking for. Fortunately, some citizens know that he is hiding near the Eastern Palace. Link must seek him in order to acquire more information and advance in his quest.

He gives Link the assignment of collecting the three Pendants of Virtue and retrieving the Master Sword from the Lost Woods. After Link has collected the first Pendant, Sahasrahla gives Link the Pegasus Boots. After Ganon has been defeated, Sahasrahla returns to his home in Kakariko Village.

Triforce Box
Throughout Link's quest, Sahasrahla will use his telepathic abilities to give Link advice when he touches a Triforce Box (the panels on the walls in most dungeons).

Trivia

 * Like Triforce Boxes, Telephone Boxes in Link's Awakening are communication devices used to speak with an Old Man, named Ulrira, who gives his advice to Link.
