Do you dare delve into the depths of an ancient demon's prison? Designed to be a fun 5E challenge-dungeon. Delve into a cave where an ancient evil was once sealed away... but be wary, as over the ages, the seals upon the Demon have begun to weaken... This is the one-shot featured in my larger adventure, Tower of the Chronomancer, but more polished and slightly expanded to allow it to stand on its own. (Originally it was the Tower's "6th floor.") I'm making this Pay What You Want, hoping people will enjoy this content -- and maybe seek the larger adventures I've already written. The Cave. Mostly hidden behind a nondescript hill in a crowded wood, forgotten by almost everyone not of the nearest town, and even they have forgotten why the cave was originally created. What it contains -- what it seals in. Marked only by a broken, rotten sign, now it's viewed as a prank spot. Sometimes it's a hideout for unsuspecting bandits. Generally, it's a place no one goes on purpose due to the lingering "wrongness" that any who enter seem to feel. Any that pass through the perfectly-rectangular entrance will find that it's much more than meets the eye. Especially if they are able to find their way down to the Trials! The Story. Long ago, a shapeshifting demon called "Umbraeus, the Defiler" sought dominion over the world. It clawed its way out of the Hells and took control of the region through a mixture of trickery (empowering people it could use) and destruction (raining fire, destroying crops and rivals, etc.). Umbraeus reigned for many years... until it was betrayed by a rival, which allowed a group of adventurers and mages to defeat and trap it in a magical green gemstone. The gem was then buried deep underground, protected by a set of Trials that allowed only those pure of heart and capable of handling its influence to visit it. But a long time has passed. The seals that held Umbraeus at bay have begun to weaken. And the demon has found a way to crack the gemstone. Its malevolent influence has begun to seep out into the world above. If nothing is done, it may manage to fully escape! Includes: A 5e one-shot adventure for 5th-6th level adventurers (4-6 hours long) Combat, roleplaying, puzzles, discovery, randomness, and loot! A chalenging demon encounter with variable difficulty levels 6 original enemy statblocks, including an evil shadow-boss 2 original magic items. Keywords You Can Expect: High fantasy, cave dungeon, combat, evil demon, shadow dragon, puzzles, discovery, randomness, gelatinous cubes, constructs, moral quandries, and lots of loot.

The carcass of a gigantic sea monster is now a small dungeon... Gargantuel was a gigantic sea monster (a whale? a prehistoric serpent? the Kraken? Leviathan itself?). She used to roam the high seas, destroying ships and devouring everything. Some of the people she swallowed survived in her belly. One of them, the sailor Torsti Seppänen, actually managed to turn the place into a comfortable habitat. One day, Gargantuel passed away. Her body now lies out in the open, luring the carrion-eater, the curious, the foolish. Strange creatures and artifacts await in the mounds of decaying flesh, and the insane Torsti Seppänen will do everything to defend his “home” from intruders. Statted for Lamentations of the Flame Princess, usable with any OSR type game. Hosted by eldritchfields.blogspot.com

Under Mirt’s Folly is a 200+ location mega-dungeon from Dunromin University Press Mirt the Long Flame was a mighty wizard a hundred years ago. He fell in love, so the story goes, with a beautiful Goddess. Using all his powers he built his true-love a temple and a pleasure palace with the intention of making her his wife. On midsummer’s eve he bent all his powers to calling her down from Olympus, luring her to our world with the sweetest compliments and tempting gifts. After several hours of calling she appeared and he proposed to her, explaining the wonderful life together he had planned for them. She was not amused. The blasted remains of the temple and the derelict palace, all made from the finest white marble, are all that remains of Mirt’s crazy ambitions. The abandoned ruins are now known by all as Mirt’s Folly. Of course, the anger of a mighty Goddess leaves deep scars in the landscape. A hundred years later the hill, despite being in civilised lands, remains an abandoned place of strange magic. It is the haunt of ghosts and monsters and all who go there return changed, fearful and anxious, if they return at all. No one knows the nature of the Curse of Mirt’s Folly and few desire to find out. But Mirt was a great mage! His powerful magic items and his many books of spells and research have never been found, not to mention the vast wealth he had accumulated. All this amazing loot must still be up there, in the ruins of the palace, or perhaps below it, in the catacombs he is said to have dug there.

In times ancient, an infamous paladin-artificer named Khaldun unearthed a cursed tome bound in the flesh of the first medusa. Driven to madness by its secrets, he used the necromantic magic contained within to call forth an army of dread warriors from the Netherworld. Though his assault was devastating, he was ultimately unsuccessful, and the mightiest crusaders of the realm banished Khaldun to the Netherworld, where he would rot for eternity at the bottom of the River Dis. Unfortunately, rather than perishing in that bleak plane, Khaldun escaped his silt grave and thrived, amassing a legion of undead followers and erecting a Tomb in which he could perfect his mechanical craft without interruption. It was not long before he shed his body and became a demilich. After several centuries of scheming, the undead warriors under the command of the ‘Iron Lich’ have burst free of the Netherworld, laying waste to not only the mortal kingdoms that exiled him, but also the exalted domains of the gods themselves. The crusaders’ quest is simple – stead the Tomb and destroy the Iron Lich. Published by Defy Danger and Save Versus Death

From time immemorial, the rulers of the mortal world have been counseled and tempted by capricious primordial spirits who rule over the elements. The greatest and most sinister of these was a half-kraken medusa known as the Maelstrom Queen, who sought to supplant the mortal races with her own line of immortal tentacled monstrosities. On the verge of her ultimate triumph, when the leviathans at her command rose from the depths, a legendary assassin murdered the Maelstrom Queen in her half-submerged palace with her own weapon. But the primordial mistress refused to let something as trifling as death put an end to her designs. Every 13 years, she regenerates enough mystic power to rise again, and the world’s greatest heroes are sent to murder the Maelstrom Queen once more.

The Last Point is a prison and outpost of the Corrive Empire, a realm ruled by a cruel green dragon named Lady Corrive. The Corrivians are well known for their hatred of magic users, and their extensive slave trade industry. A forest realm with coasts on three sides and mountains running through the center, Corrive is rich with a variety of resources. However, the rocky northern coast is out of the way of their navy and relies heavily on hired ships to help transport various goods including prisoners and slaves to isolated outposts, training centers, and slave colonies. The northwest coast of Corrive is rocky and many parts of it are elevated, making it isolated from much of the mainland. The Last Point is a recycling center where captives meant for death row who are either deemed “not important enough” to execute publicly or “too disgraceful” to execute publicly are sent to be tortured and then killed. The place seems to operate on sort of a “well, we have too many so some have to go now” policy. The Last Point has no official deadlines for killing.
