In Old Korvosa, nightmare-spawned horrors begin stalking the district's shiver addicts, sparking a manhunt to bring those responsible to justice. What role does the strange cult known as the Brotherhood of the Spider play in the mysterious deaths, and why is the veil between the dreaming and waking worlds so thin? To solve these mysteries and others, the heroes must walk the unseen paths of Bridgefront's occult underworld, and even enter the Dimension of Dreams itself to unravel the web of intrigue concealing the cult's deadly machinations.

Beset by dangers from their own minds, the heroes must race against time to save Korvosa—and their sanity.

Men always seek the blood of monsters. Some spill it to avenge their massacred families. Others swim through an ocean of gore to find treasures worth the envy of kings. A few know blood can be a priceless treasure in and of itself. Alchemy has long used the lifeblood of monstrosities as arcane fuel, and of all the legendary beasts, the blood of the gorgon holds the most secrets. Few know the blood's darkest lore, its ability to draw out the monster within every soul. Those who drink gorgon's blood are forever changed, and the darkest horrors of their mind unleashed. The heroes hunt a deadly murderer who stalks the streets of the Free City of Zobeck after nightfall, and cross blades with a guild of monsters who rule the city from below. Lucky heroes might risk no more than their lives. Unlucky heroes must wager their souls in a game where monsters and men dance close enough to share their blood and their fate.

A terrible plague has swept through the city of Cairdus, and despite the local clergy’s best efforts, they have been unable to control the spread of the disease. Even those who seem cured often contract the disease again. The only thing that is making any headway are the special blessings given by the powerful Baron Velstaf, but he only grants these blessings for a price that few can afford. The Star of Olindor is an adventure designed for 7th-level rogue, or other character of similar abilities. The obstacles in the adventure are set up to encourage the use of stealth and trickery, and many rely on classic rogue skills. The adventure takes place in the city of Cairdus, the details of which have been intentionally left imprecise, so that it can be easily slipped into an existing campaign, or better yet the adventure can be altered to take place in any existing city. Part 1 of the Olindor Trilogy.

The strange city of Carrion Hill has long loomed over the surrounding swamps in eastern Ustalav, yet its rulers have shifted many times through the centuries. Often enough that only a few sinister scholars and curious minds know the true nature of the hill’s original inhabitants—vile and depraved cultists of the Old Gods. Yet this morning, a dreadful recrudescence rises from the depths of buried nightmare in the vaults below Carrion Hill. A monster stalks the twisted alleys of the city, spreading panic before it and leaving destruction in its wake. Can the Carrion Hill Horror be stopped?

Alkenstar, City of Smog, is a bastion of civilization in the magic-warped region known as the Mana Wastes.

It falls to the PCs to venture beyond the city walls to find the source of their strange behavior.

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.
