An adventure for those seeking inspiration, but you can easily flip this PDF to any D&D version or game system. If you need help on conversion, I created this page for such an occasion: Convert Old Dungeons and Dragons Adventures
This D&D game adventure is designed for a party of 3-6 characters of levels 3-5. The party should be largely composed of dwarves or beings friendly toward dwarves (stout halflings, humans, and gnomes in particular). Player characters should be predominantly good in alignment. Detective work is involved to a greater extent than is combat in this adventure.
