Where can I unload my ill-gotten goods?
Being the greedy thief that I am, I've plundered the citizens of Gorhart and grabbed just about everything that isn't nailed down. However, they must brand their initials into everything there, because none of the shopkeepers in Gorhart will buy my stolen goods.
In general, what types of merchants will purchase my stolen goods, and more specifically, where's the first place in the game that will let me offload them?
Any merchant will buy stolen items from you if you have maxed out your mercantilism skill tree. This requires at minimum, level 18, and is probably not something you should shoot for right off the bat.
If you want to sell your stolen items before that, you'll need to find a fence. There's one at Star Camp.
