Part megadungeon, part underground expedition, Operation Unfathomable serves as both a one-shot adventure and a campaign framework. PCs are (optionally) drafted at swordpoint to recover the Nul Rod, a priceless artifact that was recently lost in a local prince's foolhardy attempt to destroy the Chaos Gods of the Underworld. The PCs have been drafted as an expendable set of pawns to venture into the vast and bewildering Underworld and retrieve the Nul Rod. With the Underworld's innumerable beasties being on high alert after the prince's expedition, the PCs must sneak through the incredibly dangerous Underworld. Fighting is not as important as stealth, fast-talking, and running away rapidly. This is the expansion from Sholtis's original Operation Unfathomable, released in Knockspell #5 (2011).

The Frozen Necromancer is a three-part adventure for Fifth Edition that takes player characters from levels 1 to 4. This adventure is the first in a storyline of four modules called The Demonplague that can be used as an entire campaign that takes characters from level 1 to 20. The entire adventure (or just pieces, characters, or encounters from The Frozen Necromancer) can be dropped into any fantasy setting with minimal changes

Goblins have returned to the area of Westgate, seeking an ancient magical item constructed for their foul kind. In their search, the goblins attack an imperial convoy secretly disguised as a merchant’s wagon. The knowledge that goblins are near must be kept quiet from the public, thus a small band of adventurers is required to seek out the creatures and the stolen magic item, deep inside the warrens of the great goblin chief! But the adventure does not end there...

The adventure begins with the characters discovering the recently murdered Returned, Varyas, and confronting his killers. Varyas's gold mask bears a code on it, one that points toward the sage Khea who lives in the nearby polis. When the characters investigate, they learn from Khea that the writing is undecipherable except for the first line, which refers to the legendary Court of Orestes, a site sacred to the god Phenax. She also notes that a recent earthquake has uncovered a cave along the Khystonos River that could be the secret site's location. If so, then perhaps within lies the key to deciphering the mask, along with its own treasures. With the information provided by Khea, the adventurers set forth into the wilds, where they'll face multiple storied dangers before reaching the Court of Orestes. Once at the lost holy site, the characters discover ancient guardians, as well as an unliving entity with the potential to reveal Phenax's lost secret.

Straight from the garage of Chris's mom—and 1981—comes this homegrown, truly old school adventure of malign druids, twisted tree demons, evil blink dogs, arboreal gelatinous cubes, magical pecans and certain death. Though sadly missing half its original key, the release has been painstakingly recreated by the author as a grown man. More or less.

Everyone in the city eagerly anticipates The Arena's opening at the end of every month. This month, an unexpected change to the lineup just days before is rife with rumours! The most feared and respected gladiator in history, Imhullu, the Dragon of Marduk, has issued a challenge to an unknown rival—a fight to the death on charges of heresy. Rumours of insults and slander are spreading throughout the Great Market, though the truth remains inscrutable. The crowds gathered outside The Arena are beyond belief; people must have come from every dimension. Gaining entrance to The Arena is going to be next to impossible. Also, you don't have a ticket! Fortunately for you, you haven't spent your youth in a particularly productive manner! Centred around a gigantic arena full of gladiators, your adventurers must brave the depths of The Pits evading and fighting strange, horrifying creatures, in order to gain entrance. Once inside, they must hold strong against social and political pressures in the hopes of finding a seat in time to watch the main event! But have they gotten themselves caught up in secrets best left alone? There’s only one way to find out!

In what became known as the Age of Madness, an astral lich calling himself the Crimson Hand descended from the sea of stars, setting his fell gaze upon Gaea. Her red moon he made both his temple and his phylactery, and from there he sought to enslave those who would be ruled and devour those who would not. The Ancients of the four corners of Gaea united their knowledge against this threat, constructing a colossal golem, and inscribing the four POWER WORDS upon four scrolls. These scrolls they fed to the colossus, who ascended to the crimson moon in an instant. The sages of the realm watched as the flashes of battle signaled in the night sky, ending as the crimson moon itself split in half. The lich and the colossus were destroyed, and the Age of Madness was ended. Millennia have passed, and now a new threat rises from the netherworld. The four POWER WORDS have been forgotten, lost among the shattered remnants of the moon. The sages have once again united what remains of their power, this time to teleport a paltry handful of crusaders to retrieve the lost scrolls before the world is doomed.

You stand before the Sha’sal Khou elders as the most diverse gith hunting party ever assembled. Are you powerful enough to keep the mind flayers from enslaving your people once again? You’ll have to race across the planes to find out. A six to eight‐hour adventure for six players.

Heroes and blackguards of every stripe will find peril on the Purple Planet, but none more than 0-level PCs. Cast across the cosmos, surrounded by hordes of baying man-beasts, and marched into mass gladiatorial combat, the PCs' death waits with bated breath. Their sole hope for escape lies – not in pitched combat against endless hordes – but by braving the unknown and pressing into the darkness beneath the Purple Planet.

The Legend of the Black Monastery Two centuries have passed since the terrible events associated with the hideous cult known as the Black Brotherhood. Only scholars and story-tellers remember now how the kingdom was nearly laid to waste and the Black Monastery rose to grandeur and fell into haunted ruins. The Brothers first appeared as an order of benevolent priests and humble monks in black robes who followed a creed of kindness to the poor and service to the kingdom. Their rules called for humility and self denial. Other religious orders had no quarrel with their theology or their behavior. Their ranks grew as many commoners and nobles were drawn to the order by its good reputation. The first headquarters for the order was a campsite, located in a forest near the edge of the realm. The Brothers said that their poverty and dedication to service allowed them no resources for more grand accommodations. Members of the Black Brotherhood built chapels in caves or constructed small temples on common land near villages. They said that these rustic shrines allowed them to be near the people they served. Services held by the Brothers at these locations attracted large numbers of common people, who supported the Black Brotherhood with alms. Within 50 years of their first appearance, the Black Brotherhood had a number of larger temples and abbeys around the kingdom. Wealthy patrons endowed them with lands and buildings in order to buy favor and further the work of the Brothers. The lands they gained were slowly expanded as the order’s influence grew. Many merchants willed part of their fortunes to the Black Brotherhood, allowing the order to expand their work even further. The Brothers became bankers, loaning money and becoming partners in trade throughout the kingdom. Within 200 years of their founding, the order was wealthy and influential, with chapters throughout the kingdom and spreading into nearby realms. With their order well-established, the Black Brotherhood received royal permission to build a grand monastery in the hill country north of the kingdom’s center. Their abbot, a cousin of the king, asked for the royal grant of a specific hilltop called the Hill of Mornay. This hill was already crowned by ancient ruins that the monks proposed to clear away. Because it was land not wanted for agriculture, the king was happy to grant the request. He even donated money to build the monastery and encouraged others to contribute. With funds from around the realm, the Brothers completed their new monastery within a decade. It was a grand, sprawling edifice built of black stone and called the Black Monastery. From the very beginning, there were some who said that the Black Brotherhood was not what it seemed. There were always hints of corruption and moral lapses among the Brothers, but no more than any other religious order. There were some who told stories of greed, gluttony and depravity among the monks, but these tales did not weaken the order’s reputation during their early years. All of that changed with the construction of the Black Monastery. Within two decades of the Black Monastery’s completion, locals began to speak of troubling events there. Sometimes, Brothers made strange demands. They began to cheat farmers of their crops. They loaned money at ruinous rates, taking the property of anyone who could not pay. They pressured or even threatened wealthy patrons, extorting money in larger and larger amounts. Everywhere, the Black Brotherhood grew stronger, prouder and more aggressive. And there was more… People began to disappear. The farmers who worked the monastery lands reported that some people who went out at night, or who went off by themselves, did not return. It started with individuals…people without influential families…but soon the terror and loss spread to even to noble households. Some said that the people who disappeared had been taken into the Black Monastery, and the place slowly gained an evil reputation. Tenant farmers began moving away from the region, seeking safety at the loss of their fields. Slowly, even the king began to sense that the night was full of new terrors. Across the kingdom, reports began to come in telling of hauntings and the depredations of monsters. Flocks of dead birds fell from clear skies, onto villages and city streets. Fish died by thousands in their streams. Citizens reported stillborn babies and monstrous births. Crops failed. Fields were full of stunted plants. Crimes of all types grew common as incidents of madness spread everywhere. Word spread that the center of these dark portents was the Black Monastery, where many said the brothers practiced necromancy and human sacrifice. It was feared that the Black Brotherhood no longer worshipped gods of light and had turned to the service of the Dark God. These terrors came to a head when the Black Brotherhood dared to threaten the king himself. Realizing his peril, the king moved to dispossess and disband the Black Brother hood. He ordered their shrines, abbeys and lands seized. He had Brothers arrested for real and imagined crimes. He also ordered investigations into the Black Monastery and the order’s highest ranking members. The Black Brotherhood did not go quietly. Conflict between the order and the crown broke into violence when the Brothers incited their followers to riot across the kingdom. There were disturbances everywhere, including several attempts to assassinate the king by blades and by dark sorcery. It became clear to everyone that the Black Brotherhood was far more than just another religious order. Once knives were drawn, the conflict grew into open war between the crown and the Brothers. The Black Brotherhood had exceeded their grasp. Their followers were crushed in the streets by mounted knights. Brothers were rounded up and arrested. Many of them were executed. Armed supporters of the Black Brotherhood, backed by arcane and divine magic, were defeated and slaughtered. The Brothers were driven back to their final hilltop fortress – the Black Monastery. They were besieged by the king’s army, trapped and waiting for the king’s forces to break in and end the war. The final assault on the Black Monastery ended in victory and disaster. The king’s army took the hilltop, driving the last of the black-robed monks into the monastery itself. The soldiers were met by more than just men. There were monsters and fiends defending the monastery. There was a terrible slaughter on both sides. In many places the dead rose up to fight again. The battle continued from afternoon into night, lit by flames and magical energy. The Black Monastery was never actually taken. The king’s forces drove the last of their foul enemies back inside the monastery gates. Battering rams and war machines were hauled up the hill to crush their way inside. But before the king’s men could take the final stronghold, the Black Brotherhood immolated themselves in magical fire. Green flames roared up from the monastery, engulfing many of the king’s men as well. As survivors watched, the Black Monastery burned away, stones, gates, towers and all. There was a lurid green flare that lit the countryside. There was a scream of torment from a thousand human voices. There was a roar of falling masonry and splitting wood. Smoke and dust obscured the hilltop. The Black Monastery collapsed in upon itself and disappeared. Only ashes drifted down where the great structure had stood. All that was left of the Black Monastery was its foundations and debris-choked dungeons cut into the stones beneath. The war was over. The Black Brotherhood was destroyed. But the Black Monastery was not gone forever. Over nearly two centuries since its destruction, the Black Monastery has returned from time to time to haunt the Hill of Mornay. Impossible as it seems, there have been at least five incidents in which witnesses have reported finding the Hill of Mornay once again crowned with black walls and slate-roofed towers. In every case, the manifestation of this revenant of the Black Monastery has been accompanied by widespread reports of madness, crime and social unrest in the kingdom. Sometimes, the monastery has appeared only for a night. The last two times, the monastery reappeared atop the hill for as long as three months…each appearance longer than the first. There are tales of adventurers daring to enter the Black Monastery. Some went to look for treasure. Others went to battle whatever evil still lived inside. There are stories of lucky and brave explorers who have survived the horrors, returning with riches from the fabled hordes of the Black Brotherhood. It is enough to drive men mad with greed – enough to lure more each time to dare to enter the Black Monastery.

A desperate ghost, a plea for help, and a forgotten crypt filled with peril and plunder. This is a tale of past conflicts, where blood magic has left a foul and dire aftermath, and time is of the essence. Maps and illustrations help guide you through rugged wilderness to re-discover a tomb lost to all but its denizens - creatures enslaved by an unholy item or awakened by its looming threat.

There is a Ruined City in the central northern Borderlands, often called Ghoultown by explorers of the area, but its original name is Ust Lesesi and it was once the second city of the Empire of Karan. Long since plundered, ruined and abandoned, the place has become home to a sinister mix of creatures, some are trading with each other, some are resting between skirmishes, all are schiming and all of them are trying to survive. This is a toy box for the GM - there are three settings in one - the Abandoned City, with stange creatures wandering the streets; the Monstrous community with several significant and detailed NPCs and their followers all trading, quarrelling and trying to get along with each other; and the city of the (un)dead - there's a whole army hidden in here, what are they being prepared for? The Ruined City is a 40-page game resource rather than a complete adventure, although it has almost everything you need for a simple hack or a more complex web of intrigue. Along with a sumptuous set of maps is a set of encounters, monster and NPC stat-blocks, and ideas for how to use the place in a campaign. If you need a ruined city in a hurry, this is the supplement for you! The Ruined City is designed for OSR but is also compatible with AD&D 1st and 2nd edition and pretty much any TTFRPG you fancy. The encounters are all pretty high level but most of the encounters will not be immediately hostile. There is scope in this setting for far more than simple hack and slash. These resources allow you to build a set of encounters as complex as you like. You can simply try and hack your way through, but there are some VERY nasty encounters in here. You could maybe set up your own base here, or just try and take over an existing group. Perhaps you want to start up a trade route, or maybe even start a Civil War! All of these possibilities, and many others, are catered for here. SM20 The Ruined City is released by Dunromin University Press. We are a very small publisher based in the UK and our aim is to produce VERY high quality products as the best value possible.

There have been disturbing signs over the last few months, signalling that something is wrong in Humblewood. The troubles appear to originate from activity in the Scorched Grove, an ashen plain that was ravaged many centuries ago by a destructive fire. Whatever caused the fire has scarred the land with elemental magic, making it inhospitable to all but strange fire-based creatures. Of late, the Grove has begun to expand. At first, it was hard to notice the slow expansion, but those in tune with nature (especially the Tenders) could see the imbalance in the elemental forces of Humblewood. For many common folk, this imbalance has been experienced as unseasonal dryness, which has led to crop failure and an increased frequency of forest fires. There have also been a number of unusually aggressive emberbat clouds reported far outside of their natural ranges. The true nature of the danger still remains hidden from the people of the Wood. A corvum necromancer named Odwald Ebonhart has stirred the elemental aspect of fire, which has lain dormant beneath the Scorched Grove since its first burning. The aspect’s energies have begun to empower fire-based creatures within the Wood. The increased range of emberbat swarms have brought fires that have expanded the Grove. Many forest-dwellers, who have been left without homes, have turned to banditry to survive. Soon the elemental incarnation will break free, and players must find a way to stop the aspect of fire before it reduces the Wood to ashes.

Ancient port city on the edge of a desert. The city is stratified by social class and some of the slaves have formed a cannibal cult to Kthulhu. City + hexcrawl + dungeon. The Anthropophagi of Xambaala™ takes players into an action-packed realm of adventure: the mythical world of Hyperborea, a sword-and-sorcery campaign setting inspired by the fantastic fiction of Robert E. Howard, H.P. Lovecraft, Clark Ashton Smith, and others. This adventure is inspired by Robert E. Howard’s “The Man-Eaters of Zamboula” and by various short tales of H.P. Lovecraft and Clark Ashton Smith. It is designed for use with Astonishing Swordsmen & Sorcerers of Hyperborea ™(AS&SH™), a role-playing game descended from the original 1974 fantasy wargame and miniatures campaign rules as conceived by E. Gary Gygax and Dave Arneson. AS&SH is compatible with most traditional fantasy role-playing games (c. 1974 to 1999) and their modern simulacra, such as OSRIC™ and Swords & Wizardry™. This work is both a setting and an adventure. The setting describes the town of Xambaala, noting key people, locations, and local lore. The adventure proper provides players with a variety of environments and the several factions fighting over them for their own goals. With a bit of skill and luck, stalwart adventurers may emerge richer and maybe wiser. The situation that will develop in Xambaala will be determined by the players’ choices.

This adventure is more of a classic dungeon crawl, themed around the accidentally terrifying dreamscape of an elven girl trapped in a nightmare of her own making. The dungeon shifts and exits move about as the party explores, making each run through the dungeon a unique experience and allowing for infinite replays of the same adventure.

"Something Fishy" - a Celtic-world campaign. "Iasc" is set in a small Celtic kingdom that can be fit into any medieval/fantasy campaign. The PCs need not be Celts. The likelihood of combat is very high, and the party is recommended to host several warriors.

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.
