Death Mountain Trail Guard

The is the guard at the gate to the Death Mountain Trail in.

Biography
He is one of the three Hyrulean Soldiers assigned to guarding Kakariko Village; the other two (at the entrance to the village and near Impa's house) are the ones who tell Link what the in-game time is.

Link must give Zelda's Letter to the Death Mountain Trail Guard, after that, the guard will open the gate and anyone can pass. If Link talks to the guard before buying the Hylian Shield, he can get a discount on it and buy the shield for just 50 Rupees at the Bazaar.

His son asked him to get a Keaton Mask. The guard buys the one that Link obtains in the Happy Mask Shop for 15 Rupees, and then will be seen wearing it. If Link refuses to give him the mask, the guard will close the gate until Link sells him the mask. If Link leaves the village or enters and exits a building, the gate will also be open again. Seven years later, when the castle town is destroyed, the Death Mountain Trail Guard can't be found anywhere.

Trivia

 * Once the Death Mountain Trail Guard has received the Keaton Mask from Link, he will wear it for the rest of the game, despite the fact that he claimed it was for his son.
