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?

Ten years ago, zombies arose from the foamy sea to take vengeance against the inhabitants of Firewatch Island. Now, they have risen again, just in time to welcome the visiting player characters! Will your heroes manage to escape the island with their lives (to say nothing of their delicious brains)?

Pgs. 19-50 Updated to 5th Edition in Ghosts of Saltmarsh

The giants are only a half-mile away - straight up. Giants and humanoids that sail down from the heavens? Where could they be coming from? No base town or general area map has been provided, as this adventure can take place anywhere and can be easily integrated into any existing campaign.The DM should make sure that the town in which the PCs start is large enough to provide most anticipated supplies, spells, and services. This module is not a simple hack·and slay expedition. It also involves diplomacy and wit; if the PCs attack everything in sight, they may be destroyed. But the adventure is not entirely negotiation, for it has a good share of hearty dungeon exploration as well. Pgs. 4-23

The characters are summoned by the Norse gods to track down two dwarves, one of whom has made a weapon for the giants to use against the gods. The mission takes the characters to Jotunheim, on the plane of Gladsheim, to take the god-slaying weapon from the giants.

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

"A great cat sits upon the northern grasslands, my friend, waiting to pounce on adventurers just like you." As you part the tall grass with your sword, the words of the tavernkeeper echo in your head. "He was the mightiest wizard we'd ever known, and that Lion Castle was his home." Your friends' voices mingle with the tavernkeeper's. "He's but a ghost now, haunting those halls, and waiting for an heir." The ground rises slightly. A strong wind rushes through the field. Suddenly, the grasses part, and Lion Castle rises majestically before you! "Magical riches await those who enter!" "Beware of man-beasts!" Voices flood your head again. Will you brave the haunted castle? Can you afford not to? It's all up to you in this D&D Solo Adventure. Ghost of Lion Castle is for one player only, but that one player makes all of the choices and enjoys all of the rewards. An entire castle and courtyard await your exploration.

But these tales of the labyrinth are only legends, really, nothing more than stories used to frighten children at night - until a mysterious scepter is found, bearing within its crystal head a visage of insanity and terror, and also delivering a message: "Disturb not the Labyrinth of Madness again, and live a while longer."

Somewhere under a lost and lonely hill of grim and foreboding aspect lies a labyrinthine crypt. It is filled with terrible traps and not a few strange and ferocious monsters to slay the unwary. It is filled with rich treasures both precious and magical, but in addition to the aforementioned guardians, there is said to be a demilich who still wards his final haunt (Be warned that tales told have it that this being possesses powers which make him nearly undefeatable). Accounts relate that it is quite unlikely that any adventurers will ever find the chamber where the demilich Acererak lingers, for the passages and rooms of the Tomb are fraught with terrible traps, poison gases, and magical protections. Furthermore, the demi-lich has so well hidden his lair, that even those who avoid the pitfalls will not be likely to locale their true goal. In the far reaches of the world, under a lost and lonely hill, lies the sinister TOMB OF HORRORS. This Labyrinthine crypt is filled with terrible traps, strange and ferocious monsters, rich and magical treasures, and somewhere within rests the evil Demi-Lich. TSR 9022

From time out of mind, the standing stones known as the Circle of Cahervaniel have stood lonely vigil on a grassy hilltop. Sheepherders once moved their flocks over the hill and through the circle, sometimes resting in the cool shadows cast by the ancient stones. Everything changed when a stone finger fell, revealing a fissure in the earth. Now, dark shadows caress the circle after the sun sets. Creatures out of nightmare dance upon the hillside at night. Many swear that a unicorn of deepest ebony now hunts all upon two legs who draw near, while stunted creatures scurry in the shadows, abducting sheep from their sheds and drawing them down below ground for food. After the disappearance of a sheperd, fear grows stronger in neighboring villages. Who will brave the black hollow of the ancient Circle of Cahervaniel? Heroes of stern mettle must descend into the cavity and explore the ancient spaces existing there. Product History "The Shattered Circle" (1999), by Bruce R. Cordell, is a generic adventure for AD&D 2e. It was published in January 1999. Origins: Another Generic. After Wizards of the Coast began publishing D&D, their first year and a half of generic adventures were all classic revivals: returns to RPGA tournaments, to classic adventures, and to Dungeon scenarios. Even "A Paladin in Hell" (1998) was a return in its own way, to the demons and devils that TSR had become afraid of. Wizards was staking out new ground by reclaiming the past. "The Shattered Circle" (1999) was the first generic Wizards adventure that was simply a generic adventure, with no deeper origins and no hidden motives. Artifacts of Note. the foundingstone and the harp Euphonious are both one-off named magic items. However, it's sword Icerazor that's the most interesting. It's said to have grown from a shard of Frostrazor — a sword that would only appear ten months later in Return to White Plume Mountain (1999). There, it's listed as one of Keraptis' four implements of power, alongside Wave, Blackrazor, and Whelm — meaning that Icerazor (and this adventure) are just one step removed from White Plume Mountain itself. Monsters of Note: Chitine. It's somewhat curious, given the Greyhawk and Neverness connections, to note that the chitine debuted in MC11: "Monstrous Compendium Forgotten Realms Appendix" (1991). The spider-humanoids have generally been a Realms creature, featuring in bestiaries and histories for that setting. However, they also received a more generic "Ecology of the Chitine" in Dragon #223 (November 1995), which introduced the choldrith, or chitine priestess. This is their major adventure appearance. When asked about pronouncing their name Cordell says that he "can't be 100% sure of the original designer's pronunciation", but he prefers "KI-TEEN". About the Creators. By 1999, Cordell was one of D&D's most prolific writers. He'd previously authored many slightly related adventures, such as The Gates of Firestorm Peak(1996) and the sahuagin (1997) and illithid (1998) Monstrous Arcana adventure trilogies. This conversion guide allows DMs to run the original module with 5th Edition rules. To use this conversion guide you will need a copy of The Shattered Circle, originally available in hard-copy and now for sale in Digital format at the DMs Guild. This adventure is a generic adventure, not specifically based in any existing setting. Suggestions are given in the conversion guide to place the adventure in the Forgotten Realms.
