Lockpicker

The Lockpicker is a character from The Legend of Zelda: A Link to the Past. He is a former locksmith, living under the guise of being an ordinairy man, albeit a mute one. He resides near the Desert of Mystery. If Link picks up the nearby sign, the Lockpicker will break his otherwise unbreakable silence and follow Link until he leaves the area.

Biography
Prior to the events of the game, the Lockpicker was thief who specialized in the picking of locks; however, he apparently denounced his ways or was forced out of his occupation, and passed himself off as an ordinairy man, making his residence at the entrance of the Desert of Mystery.

After hearing about the Lockpicker from a thief in the Lost Woods, Link comes across him while on his journey to retrieve the Pendant of Wisdom. Upon conversing with the man, Link receives no reply and simply moves on. Link later returns to the man with a chest he found in the Village of Outcasts. Realizing that he has been found out, the Lockpicker offers to open the chest for Link in exchange for him not telling anyone about his true identity. The Lockpicker unlocks the chest in the blink of an eye, and gives Link the bottle that was inside in exchange for Link's silence. He then asks Link to leave him be.
