The moon is turning green. A colossal tide of green slime has begun to engulf it, threatening to dissolve it entirely. As it does so, a tide of demonic madness begins to engulf the lands below. As the green shadow flows across the night sky, the world turns mad. The source? An insane cult of plasmoids dedicated to Juiblex, the demon lord of oozes and slimes. Soon the moon may be gone, the first part of a mad plan to dissolve the multiverse into the primordial slime of the Abyss. If only some heroes could appear before it’s too late... The Ooze That Ate The Moon is 5th-edition Dungeons & Dragons adventure based on the Spelljammer campaign setting. It is an investigative high-orbit pulp thriller paired with the wacky zaniness of Spelljammer, and every playthrough is likely to be different. It is designed for four 9th or 10th level characters and to be run in 3 to 6 three-hour sessions, or 2 to 3 longer sessions. It can be run as multi-session one shot or as part of an ongoing campaign. It fits perfectly after the events of Light of Xaryxis, but is written so as to be easily incorporated into any non-Spelljammer campaign. It requires the 5th Edition Spelljammer boxed set to run. Gameplay is based around investigation and roleplaying, with a good smattering of combat in the later acts. The climax of the adventure presents the players with a problem that has no clear solution. They’ll have to use all their wits and resources to overcome it, but can they do so in time?

Under raging stormclouds, a lone figure stands silhouetted against the ancient walls of castle Ravenloft. Count Strahd von Zarovich stares down a sheer cliff at the village below.
