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 leader of all the Shadow Guilds, the Ceta Consortium is gone, wiped out in a single night, without warning or witnesses. Their empire of control, secrecy, and soft-handed rule has vanished, leaving behind only rumors and blood. Now, the city of Lumina stands on the edge of something new... and something dangerous. Shadow Guilds is a system-agnostic tabletop campaign setting built for fantasy games that blur the line between ambition and morality. Set in a bustling metropolis of vice, corruption, and uneasy power, it invites players to step into the roles of underworld mafiosos, trying to make their mark—or just survive the fallout. Inside, you’ll find everything you need to run a campaign focused on gang politics, black-market enterprise, and the slow scramble toward power in a world that rewards the bold and punishes the careless. You’ll build a crew, carve out territory, and navigate a world where magic is outlawed, alliances are temporary, and opportunity lurks behind every closed door. This is not a story of chosen heroes or grand prophecies. It’s a story of clever rogues, ruthless enforcers, and ambitious criminals rising into the vacuum left by the old guard. The game leans into roleplay, style, and smart decision-making—but it doesn’t shy away from trouble when it finds you. Start small. Lie often. Watch your back. Shadow Guilds is a system-neutral campaign setting designed to drop into any fantasy world where criminal syndicates thrive in the shadows of power. Whether you're running a long-form campaign, a gritty one-shot, or threading a criminal conspiracy into your existing world, this guide provides the building blocks for a dangerous, decadent underworld full of secrets, turf wars, and moral gray areas. This setting assumes a single sprawling metropolis, where various criminal guilds operate openly or in secret. It leans into noir fantasy, urban intrigue, prohibition, and the uncomfortable alliances forged when justice fails.

It's a frigid New Year's Eve, and the heroes gather near midnight in a small condemned tavern wihtin the Free City-State of Gate Pass. Located in the mountain pass which separates two hostile nations. Gate Pass has been neutral since the end of their last war. That neutrality is about to be put to the test, as a scourge comes for the city from the nearby empire of Ragesia. By now, every magic-user in Gate Pass knows of the Scourge. The Emperor of Ragesia died barely a month ago, and a witch named Leska has moved to cementer herself as the next empress. Leska leads the Ragesian Inquisitors, clerics specialized in countermagic and has decreed ass disloyal mages to be tracked down and killed to prevent future threats to the empire. Their first target is Gate Pass, whose neutrality has long been viewed as an insult to the nation's honor. This is the first of twelve adventures in the War of the Burning Sky adventure path from E.N. Publishing.

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.

Darwell Umbruskor has long been known around town as an eccentric but ultimately harmless old sage. From what you've heard, he keeps odd hours, rarely speaks a word to anyone, and lets no one enter his tower save for a few servants. Though quiet and mysterious, Darwell has done nothing to around undue suspicion. Sir Jeffers, a crusading warrior who just made your acquaintance, claims otherwise. According to evidence he recently came across, Darwell Umbruskor is both a necromancer and a dedicated priest of an evil power. Published by Fantasy Flight Games

Something fell. A sickly gloaming lit up the night like mock daylight, just for a moment, and then the hills trembled. Now, an alien entity lies brooding in a crater gouged out of the moor. Local folk are enraptured with the toothsome jelly exuded by this being, but are blind to the true nature of the events unfolding in their rustic little backwater.

This campaign was created as a response to comments from some friends of mine. Though they were avid board game players, they didn’t want to try D&D because it seemed like too much of a time commitment with too many rules to learn before getting started. This campaign uses stripped down characters and a simple campaign, and was made to give them a chance to try it for half an hour on a regular board games night. I’m putting it online in the hopes that other people can do the same with it and expand the community. Inspired by /u/plaintreality of Reddit.

The mountainous lands of the Last Kingdom have long been home to dangerous oni and their foul servitors and kin, but the unification of the Saigoto under the enlightened rulership of the Five Truths has sent them scurrying back into darkness. For years since, they have kept the land shielded from harm. Yet even the great soldiers garrisoned across the Kingdom’s shores and roads cannot stop dissent from boiling up in the shadows. Not everyone embraces the edicts of the land—and while patient teachers, even the Five Truths have their limits. As growing numbers of lastfolk begin to question the traditions of the Last Kingdom, forces far more sinister, preying on the curiosities of mortals, have begun to emerge into the light... Can the PCs discover and end a treacherous plot that threatens to destroy the relative peace of the Last Kingdom?

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.

Deep in the wooded wilderness, the village of Grimmsgate is an outpost town on a seldom-traveled trail, right at the edge of nowhere. The village’s half-ruined temple of Law, dilapidated inn, drunken blacksmith, exiled trader and a few fur-trappers are enough to keep the bloody-minded denizens of the dark forest at bay, but nobody really expects the village to still be there in another ten years. The woods have become too dangerous for the trappers who once caught animals for fur, and merchants no longer travel the poorly-maintained road. What great evil and what fabulous treasures are to be found in these lands? A brave band of adventurers might make their fortunes here. Or perhaps they might never return… Grimmsgate is an introductory adventure for the Swords & Wizardry tabletop roleplaying game. The Swords & Wizardry rules are needed to play this adventure.
