Dragonpit

The ancient black dragon Nahud fought his final battle in the air above modern Dragonpit with the elf Zehaus, a fearsome wizard. Nahud swallowed Zehaus whole, including the wizard’s many magical devices and his jeweled wand. Moments later, the great dragon plummeted to the ground, creating a large pit. His body instantly turned to a tar-like goo. To this day, toilers dive into the goo to find his scales, still in perfect condition despite at least 10,000 years.
