Old Man
From Zelda Wiki.org
The Legend of Zelda
In The Legend of Zelda, there are several old men across Hyrule, each serving various needs, such as supplying Link with his first sword, or giving helpful hints regarding enemies such as the Dodongo. Many helpful items can be obtained from these old men, and a mini-game can be played with them called the Money Making Game. Sometimes however, they will take Link's money for "door repair" upon entering one of their hidden caves.
The Adventure of Link
In The Adventure of Link, there are several old men residing in many of the towns. These old men teach Link useful spells once he has achieved the necessary prerequisites. These spells are required for access to the next area that Link must travel to.
A Link to the Past
A single old man appears in A Link to the Past when Link first enters Death Mountain. He is quite lost and is missing his lantern. He asks Link to aid him in getting to the safe house on the top of the Mountain outside the caves. Once the way is lit by the light of Link's Lantern, the old man helps guide him to the top.
For helping him, the old man rewards Link with the Magic Mirror. He will also aid Link anytime whenever he comes to his safe house by refilling his life energy. While leading him through the mountain, the old man will talk about how he has a daughter who was abducted by the wizard Agahnim, as a part of his plan to break the sages seal. This reveals that the daughter is a maiden, and she and her father are both descendants of the ancient sages.
