The Unlikely Adventurer
Gnarl was born with aspirations and a desire to learn about the world around him. It was these two desires that convinced him to aid Leetham in recovering the Shield of Five Suns from the depths of the Gray Mine. Gnarl since followed Leetham through his adventures and learned a great deal about human culture. He eventually retired to the village he was born in.
It is now known that Gnarl has died. It is likely this happened since the last time Leetham visited or he would have mentioned this.
