Sanvill Trett is a wandering merchant and tinker who travels around southern Numeria. He has a particular interest in technological items, and will pay quite well for any of the peculiar artifacts discovered in the ruins from the Rain of Stars. For a small fee, he can also identify items even if the owner isn’t interested in selling.
Unbeknownst to the rest of the town, Sanvill was actually a low-ranking agent of the Technic League. He took a great interest in the torch going out and the ruins underneath Black Hill, and accompanied the party to see what he could find out. Though they had their suspicions, they allowed him to come along so they could keep an eye on him.
He turned on them in the middle of a fight with a gargoyle, but was subsequently killed.
