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.

A little cave-borne adventure about harvesting valuable cysts from a sleeping creature, trying not to be killed by the horribly mutated infectious things that already tried that, and helping a wizard who recently lost all his friends and just wants to get his spellbook back. For use with your fantasy RPG of choice. How would I use this thing? -As a terrible one-shot without consequences! -Drop "Find the wizard Felix Longworm cowering by stones and a mournful tree" into your mountainous random encounter table of choice, and pull this out when the fates decide. -If the cave is ignored something else will eventually be birthed out of it, so you get free campaign fodder if your players shake their heads and say "nope". Apart from the adventure it also contains a glorious suit of cursed armour, horrific explosives, four new spells, an adorable cut-out map for your players to put together as they explore, and some pretty neat light tracking mechanics, so there's that.

The Dread tunnels of Ruxbar were created by a cult of a lesser evil deity of the giant pantheon, known as Jargain to serve as a planar gate in hope of bringing chaos and destruction to the natural order of the world and power to the one who would control the gate. Ruxabar was the high cultist who completed the ritual but to his surprise nothing of what he expected came through the gate. Plague creatures, toxic gases and vapors, diseases of all kinds and decay lay quick waste to him and his cult. For some time the gate remained open and the settlements nearby were afflicted with diseases never seen before. The nearby town of Stagwood was quickly abandoned due to the plague. Rumor has it that the gods have weakened the gate and the cult has been destroyed. The remaining villages that managed to somewhat resist the plague are now hiring brave adventurers to venture into the tunnels and close the planar gate for good! Are you capable enough of surviving the horrors that reside in the Dreaded Tunnels of Ruxabar? Published by Mistfactor Press

At the base of the falls, behind a massive curtain of water, is rumored to be the cavern lair of a great wyrm.

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
