Deep Mine Mystery (5E)

From publisher blurb: A 5th Edition Mini-Dungeon adventure for 4-6 characters of levels 6-8 Duergar cultists infiltrated an abandoned section of a local mine, planning to infest it with spores of their ancient fungus god by opening a planar rift. However, their preparations drew the attention of the miners, and a group of deep gnomes interrupted the ritual. Unfortunately, neither side was completely victorious; now a standoff ensues between survivors while the monstrous servants of the fungus god create a nest, threatening to expand beyond this warren of tunnels. Miners reported a formerly abandoned section of mines as haunted, with strange noises and a lift, which occasionally functioned without someone touching it. A group of svirfneblin mercenaries offered to investigate two days ago but never returned. Recently, the lift rose up out of the darkness with a bloody activation lever lying in the center of the platform. “Ghosts don’t bleed,” retorted the foreman, and quickly engaged the characters to descend into the lower tunnels and determine what happened.
