Publisher's blurb: The unconfined, viscous mass of demon lord bleeds corruption into the dark corners of nearly every plane in the multiverse. Its alien machinations that began in an embryonal Abyss ever churn toward uncertain ends. In the secluded hamlet of Rathburrow, the players will come face-to-face with Juiblex’s will made manifest. In addition to the core rulebooks (the Dungeon Master’s Guide, the Player’s Handbook, and the Monster Manual), you must have access to Volo’s Guide to Monsters, Xanathar’s Guide to Everything, and the Out of the Abyss adventure to properly run this adventure. A Two-Hour Adventure for 1st-4th Level Characters.
