But what happens when you come face-to-face with the challenge that bested the greatest adventurer in the whole Kingdom? Can you succeed where Feyr-Panniras failed?

Some time ago, the wind began to sing of death in the Sision River Valley, and if purgatory was a song, Glovakians are now listening to it. The source of this soul-crushing music was tracked to about 90 miles northwest of Ambir. What was found? A massive, oddly built stone tower that wasn't there before. Word quickly spread and the curious set out in droves. Many turned back however, as every passing day the music got worse, but a brave, or foolish few, managed to make camp and eventually go inside. If anyone's made it out, no one really knows, but there's no shortage of rumors as to what's really going on in the place that's come to be known as, Sision Tower. Sision Tower is an OSR styled, vertical dungeon-crawl where the PCs explore an odd domain of Holy origins. Here, they will test their survival skills as well as their Faith. Here, they will meet Saints and Seraphs. Here, in the struggle between Law and Chaos they have to decide.....Plunder??......Sacrifice??......or Both!!! Sision Tower includes: All original black and white art. Over a dozen, fully illustrated, new magic items. Unique monsters and a sample setting. A vertical dungeon-crawl of 35 rooms. A spiritual setting in the same vein as Praise the Fallen. Sision Tower is designed to challenge character levels 3-5 and is easily used with most tradtional fantasy role-play systems.

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.

Far below the Fields of Petrichor is a vast cavern containing the skeletal remains of a long-dead Sonorous Titan, a whale-like beast that once floated through the skies of a lost age. Amongst the bones are ravines and grottos home to bizarre creatures and lost treasures that are as beautiful and valuable as they are deadly. Ghostly shapes swim through the air. Glowing mushroom groves hide frightened creatures. And the Titan’s bones sing sadly as an ambitious wizard and his weary hirelings dig for its precious marrow...

They say the legendary Ashes of Evensong have been found! In the year 689 DR, the song dragon Evensong was incinerated by Kallurous, a red dragon. In the wake of her death, Evensong’s ashes were gathered into a hundred urns by members of the Harpers. Originally intended as mere relics, the urns fell out of the Harpers’ possession when the caravan transporting them was ambushed. They were thereafter lost to history. Three months ago, stories began to circulate that at least one of the urns has been found. An artificer from the city of Elskar claims to have acquired some of Evensong’s ashes. According to his story the ashes are more potently magical than even residuum, created as they were from the mortal remains of a powerful magical creature burned to ash in the fires of an even more powerful dragon’s breath. This tale is dismissed by most, but certain factions and private interests aren’t willing to reject the possibility without investigation. If true, the artificer may be in possession of a highly dangerous and unfathomably valuable substance. More importantly, he may be in possession of the knowledge of where it came from, and the secret of what happened to the Ashes of Evensong all those centuries ago. In search of the truth behind a rumour that some of the Ashes of Evensong have been found, the player characters find that the Ashes are ultimately incidental to a far more worrying development. The trail of the Ashes leads them to the discovery of a fiend pact warlock operating among the ruling class of the city, a vault of forbidden magics the secrets of which have been breached, and a diabolic artefact about to be reclaimed in the name of a Duchess of Hell. With a focus on investigation, puzzles, and dangerous traps, Ashes of Evensong rewards players for caution and cleverness. Published by Spilled Ale Studios

This is Part 1 of an adventure designed for characters of the 20th to 21st level About 200 years ago a horrific massacre took place on the remote Soron island of Heikun. For months, the deranged and corrupt priests had sought to create a race of hybrid Snake-Men...a race which they believed once existed in Soro. They kidnapped folk from surrounding villages and took them back to their temple. There they performed unspeakable rites and experiments. Sensing their debasement, the dark spirits of the mountains called to the priests in their dreams, luring them down into the vast sub-levels beneath the Pyramid. Somewhere in the cavernous depths they were touched by an eternal evil and given horrific new forms. The deformed priest-things of Heikun crawled back to the surface, systematically destroying all living creatures in their path, including the city's hapless, ineffective leader: the inbred boy-king Yusef.

"This is a beautifully bleak hex crawl around an island smothered in oppressive darkness and fermenting wickedness. The Sluagh and their foul fog and maddening miasma are inscrutable and unknowable, but you must investigate the Island; discover the secrets buried within and without. Collect the scraps of information and open your heart and help these people tearing each other apart and worse, or become dark and hard as flint; indulge the mercurial machinations of men lost to madness of the mists and consent to cruelty. Worse still, lose yourself completely in the blanketing fog of yore; stumble blankly into the eternal night of truly annihilating nihilism... There is still faint hope that your investigation can illuminate the mist’s mysteries, lifting Man to the light, but it’s not for the fainthearted." - Curse of Sebs The Isle of Endless Fog is a 5e adventure for characters starting at 1st-level and ending at 4th-level. It's a sandbox adventure with a small setting for The Isle of Man, a location from Fallen Camelot setting. It features all three pillars of a 5e game: exploration, social interaction and combat. CONTENT WARNING: Mental Health Issues, Depression, Disassociation, Self-Harm, Suicidal Ideation, Human Experimentation, Drugging and Abduction, Cannibalism, Murder of Civilians and Children, Clerical Abuse of Power through Tyranny. Background The Isle of Man was by no means a safe place, with sporadic assaults from the troll, Buggane, trickster fey, and conflicts of resources with the local giants, but it is still a place where local folk can live their lives in relative peace. All that changed when the sluagh came. They flew free from an ancient tower, a storm of wailing ghosts that swept across the land, carrying a blanketing fog across their backs that choked the land, the sea and the sky. The Death Mist warps all that it touches, inviting death into the homes of all things, whereupon the sluagh swoop out of the skies, snatching up souls on the verge of death, carrying them away from their bodies and into a new horrid existence as a fellow sluagh. In packs they fly, swooping through villages on the westerly winds, carrying away the souls of half its denizens, leaving the rest to starve, whereupon another wave will come to claim the rest. Over time, the mists drained the life from the earth. Fields turned barren, forests petrified, infants were born malnourished and shriveled. Yet, its hunger only grew. The sluagh called beyond, drawing travelers to Man. Sailors will see the fog first, rolling in from the horizon, before the wailing of the sluagh deafens their ears, and the mist blind their eyes. After what feels like hours, the sailors open their eyes and see Man on the horizon. The explorers will quickly find that they cannot leave this place. They must either banish the mist from this place…or destroy it. Published by Realmwarp Media

In the fetid waters of the Rotbog, the Wraith’s Breath lies wrecked. Those squalid remains were once the proud vessel of the Dread Pirate Ghostbeard, during his fanatical pursuit of the Lost Gold of Tagua. Whether he found a piece is not known, though it is said that a mere touch of the treasure can infect one’s soul with the ‘Gold’s Will’ – a compulsion to reunite the scattered booty. Perhaps that explains Ghostbeard’s mad obsession.

It can be easily slotted into an ongoing campaign, or can work as a short one-shot. The file includes a battle map - one version for the players, and one with GM annotations.
