No Prep Module: Light and Shadow - DnD - Kassoon.com

The party encounters a goblin explorer. The goblin travels alone, mapping the regions he passes through. His maps are mostly inaccurate. Notably, he has a city marked about a day's walk in the direction the party came from. There was no city there, but he insists he saw it when he passed through a few days before.
