Mystery of the Nightmare Venom is the second adventure in the Nightmare Venom campaign for the prehistoric D&D Planegea campaign setting. It is designed for four to five 2nd-level characters using the D&D 2014 ruleset. In the first campaign adventure, Venom Attack!, the PCs encountered an envenomed spider-raptor sent by the Spiderfolk Queen to attack Edgegather, while a minion of a green hag sought to collect a sample of the venom. In Mystery of the Nightmare Venom, the PCs begin to investigate this strange magical poison at the behest of the Venom Guard: A vengeful green hag seeks to corrupt the inhabitants of Edgegather. Can the PCs stop her before her poison brings the settlement to its knees? The goblins of the Unfalls may have useful information but the PCs must first retrieve a lost relic from the spiderfolk of the Venom Abyss before they can ask their questions. The PCs investigate a vast and ancient temple beneath Edgegather where the mysterious Veiled Goddess can point them towards the Oracle of Seerfall. Mystery of the Nightmare Venom contains five new monsters (the envenomed chattercrest, the envenomed Venom Guard, the cauldronborn, the Glassback spiderfolk, and the faithful remnant) and two new magic items, the bloodtallow candle and the obsidian centipede.
When huge stones fall out of the night sky, A deadly curse settles over Gravencross. Help the village exorcise the Demon Stones. “The sun had set an hour ago, and the rain lashed down and the wind howled on the dark moor. A storm this late in the season was unusual, but this one seemed different. The clouds were more menacing, tinged with anger, the rain colder and more biting than usual. Skerrill had to find the lost calf and get him back to the farm before his father came back from the city on business. He’d been looking for two hours now, and he was right in the middle of the moor when the storm hit. He knew he should have turned back as soon as darkness fell, but then he was never the brightest boy in the valley. If only he had remembered to lock the farm gate. The calf was now likely dead anyway having stumbled among the boulders and rocks, panicking in the dark, and then fallen in a floodwater stream and drowned. Either way, he was in more trouble than he could imagine. Suddenly, a bright flash of white light and a roaring peal of thunder were preceded by an explosion as a huge object fell from the sky and impacted the ground of the moor no more than a stone’s throw from him. Dirt, mud, water, and debris erupted from the impact site, flying high into the air and then covering the moor for hundreds of feet all around. Skerrill was knocked to the ground instantly and covered in the fallout from the blast. His ears rang and his head spun, but he staggered to his feet in a daze. He stumbled to where the blast had happened only moments before, and in a depression in the ground lay a huge stone glowing orange as if hot. Skerrill passed out. Two more thunderous explosions crashed in the distance.”
