The Ooze that Ate the Moon

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?

The Ooze that Ate the Moon features:

• A flying saucer piloted by plasmoid cultists of Juiblex. With laser guns.

• An entire city affected by the Madness of Juiblex.

• A reclusive astronomer, desperate to hide the fact she’s secretly a werewolf.

• An erratic lunar dragon.

• A druid who retains his beard while in animal form.

• A mad giff with a belly full of gunpowder.

• A sentient piece of cheese in control of a sphere of annihilation.

• A chance of being attacked by a demonic curry.

• A ship full of space-clowns harvesting slime to bake into acid-filled pies (with the possibility to be turned into a space clown!)

• A treacherous glabrezu confined to a giant beanbag.

• Demon ichor infusions (to be applied surgically, accidentally or violently)

• And of course the main villain, ‘Juiblex Junior’, a plasmoid boss warlock thrall of Juiblex, with an unlikely path to redemption…

Also included are:

• Over 40 pieces of original Spelljammer-themed art

• Specific notes for incorporation into Dungeon of the Mad Mage

• Encounters and chapters formatted for easy reference during play

• Breakdowns of possible player/NPC actions and their outcomes

• Potential complications and their resolutions for each chapter

• Scripted dialogue options for all major NPC encounters

• Just a bit of humor (because reading adventures can be so dry sometimes)
