The Claret Wellspring is an adventure for four 4th-5th level PCs. "The first spell cast has not yet finished its work." Strange lights in the desert lead the PCs to a long-forgotten oasis. Travelling towards the lights, the PCs are threatened by magic so old, it defies categorization.

Turning the dial results in the water being magically siphoned into the column's hollow cavities. If the pool is emptied, a small door is revealed in the crimson-stained much. They must defeat a blood-infused water elemental before proceeding. Once inside, the PCs share a room with a dark ritual running since the origin of the world. The keeper of the place, an immortal fey inside a powerful suit of armor, offers little explanation as to the nature of the ritual, and he seeks to ensure they tell no one of the Claret Wellspring.

The trouble began several weeks ago when a duergar excavation team went to work in a long-abandoned temple. Drawn to the temple by stories of riches and artifacts, the duergar hired several giants as laborers before cracking the temple’s sealed doors. The largest of the giants, a loathsome Thursir mutant named Huppo, used his acidic vomit to expedite tunneling into the temple’s collapsed hall of worship. Then, Huppo found the horn—an unusual instrument made from a single piece of stone, with a mouthpiece so intricate only a master carver could have made it. The horn became the giant’s obsession. Seeing only the horn’s potential sale value, the dwarves demanded Huppo turn it over to them, but Huppo refused. To force compliance, the dwarves stopped feeding the gluttonous brute, but Huppo had already found his own source of food; in deep areas of the temple, worms were chewing out of the rocks, and Huppo ate them by the fistful. He also played the horn. Then, after several days of blowing the horn and devouring the strange worms, Huppo released a belch so noxious the dwarves had no choice but to lock him in a sealed chamber and carefully consider their next move. The horn’s call, however, had caught the attention of passing nomadic orcs. They set up camp outside the temple entrance in the hope of finding the horn and its player. That’s the current situation at the temple: the giant refuses to stop blowing the horn and belching out deadly clouds of stomach gas; the dwarves are frightened and edgy while their leader is obsessed with malevolent whispers; orcs are threatening to overrun the place; and the population of worms grows steadily as something awakens deep in the stone beneath the sanctuary of belches.
