Buried deep below the earth is an old duergar wizard’s complex. Once upon a time it hummed with activity as the duergar wizard Sorcha and her assistants researched and experimented with the creation of half-dragons. Now, it lies in ruin, consumed by a parasitic fungus. Its former occupants roam its festered halls in search of fresh bodies to infect.
