Just when you thought you knew every nook and cranny of your favorite game, someone tells you that there is a hidden NPC in the cave of desires. Win, and you get a new companion that also sells wares at a discounted price at camp. Lose, and you become his new companion. Good luck, adventurer.

This was done by  PinkGatorPress which I commissioned during FWA 2017. The theme was video games, so why not get something related to it? He sells you magical items, like the gloves he's using, but he doesn't have a decent pair of pants for himself!
