The Drift Crisis has flung the crew of the Primorata across time, space, and other planes. Now Desna?goddess of dreams, stars, and luck?has chosen them to help those imperiled by the Drift Crash. Soon they're rescuing a solarian cosomonastery from a colossal black hole and finding a family of explorers trapped on the Astral Plane and lost along the River of Souls. And although Desna may have welcomed them to Cynosure, her personal home inside a star, the crew quickly discover their enemies have followed them and now threaten Cynosure itself! “Nightmare Scenario” is a Starfinder adventure for four 3rd-level characters, continuing the 3-volume Drift Crashers Adventure Path. Drift Crashers is part of the Drift Crisis, an event taking place across the entire Starfinder game line, in which faster-than-light travel breaks down and the galaxy is thrown into chaos. In addition to the adventure itself, this book includes an article expanding on Desna and her church in the Starfinder setting, a gazetteer of her home plane of Cynosure, and an Adventure Toolbox filled with new rule options and strange alien creatures. Each bi-monthly full-color softcover Starfinder Adventure Path volume contains a new installment of a series of interconnected science-fantasy quests that together create a fully developed plot of sweeping scale and epic challenges. Each 64-page volume also contains in-depth articles that detail and expand the Starfinder campaign setting and provide new rules, a host of exciting new monsters and alien races, a new planet to explore and starship to pilot, and more!
