King Yolkar

 is an NPC found in the Goblin Holdout in the Crystal Hollows. When talking to him and giving him, he will give the player the King's Scent potion effect for 20 minutes, allowing the player to sneak past the Goblin Queen's guards into the Goblin Queen's Den and to obtain the Amber Crystal. His name may be based off of the word yolk, which may explain his constant hunger for Goblin Eggs.
