The Night of Dissolution (5e & Cypher System)

A hidden conspiracy draws the characters into a web of insane cultists, wild chaos magic, and primordial horrors beneath the city of Ptolus. While a barbarian horde ravages the surrounding lands and lays siege to the city, the characters investigate urban intrigues, explore dangerous dungeons, and confront the Cults of Chaos. The adventure includes the haunted Pythoness House, a secret temple dedicated to the Galchutt, and a city-wide network of spies reaching into Ptolus’s highest society. It culminates in a race to prevent the awakening of the slumbering Galchutt and the catastrophe foretold as the Night of Dissolution.
