Thieves Guild

While they have a few small hideouts on the surface of Springs Dawn, most of their operation is in the sewers of the city. The slaves they kidnapp (not high elves) are taken to a Ray Island just north of the Forgotten Marsh right off the coast. On the isle there are boats that brings the slaves to be to Mocotra, a southern country with a thriving slave economy.
