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.

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).

Prison of the Hated Pretender is an introductory adventure for 4-6 characters levels 0-1. Originally published on the Dungeon of Signs blog, it is a short drop-in location-based adventure with a couple of interesting puzzles, a lack of "book" monsters, implacable foes with an obvious weakness, and a very weird roleplaying opportunity. The new 2020 edition republished by Hydra Collective adds suggested guidance for new Dungeonmasters who grew up with 5th edition and don't know how old-school works. Stats for both BECMI and 5th edition, and setting neutral (though there are some implied things about the history of the world).

Capable of challenging even the most experienced players and most powerful characters, The Dreams of Ruin are an unforgettable addition to any high-level campaign. But beware! The dreams are mighty and can overwhelm even fearsome warlords and powerful wizard-kings. One touch of them, and your campaign world will never be the same.

The ancient world of Harth withers beneath its dying sun…but it’s not dead yet. Welcome to the strange and dangerous city of Carcassay, huddled below the skeleton of a titan rat, sprawling above the ruins of countless dead civilizations. This is where folk come to find wealth, power, revenge, secrets, oblivion… and everything in between. Carcassay is a sandbox city adventure. There are many locations to explore in, around, and under the city. Players can explore any place at any time, and may radically reshape the city’s politics, economy, religions, and physical existence. There are standard dungeons stacked under the city, and GMs are encouraged to keep adding more dungeons… all the way down. Tone. It leans more toward low fantasy or sword-and-sorcery. Most shops look like real shops. Most people look like real people. But strange and horrible things lurk everywhere as soon as you start to scratch the surface. This is my Lankhmar. Carcassay is a vast, bizarre city. It has over 100 locations where you can meet Chaos cultists, Lawful knights, retired adventurers, shopkeepers, brewers, musicians, artists, scientists, hermits, royalty, beggars, doctors, space vampires, eldritch horrors, machine priests, crab colonists, mushroom farmers, mummies, assassins, and diplomats from distant lands… and the moon. And every one of them has goods or services to sell, and a quest (or three) to offer. What sort of quests? Fetch a relic, assassinate a rival, find a relative, steal a soul, implant an agent, cure a disease, stop a riot, solve a murder that hasn’t happened yet, hunt a thief, locate a shrine… the list goes on. And for every Quest, there is a specific Reward: money, weapons, relics, Chaos mutations, exclusive memberships, information, Angelic miracles… the list goes on. This is a place where you can make a lot of money, but also where you can spend that money on interesting goods and services. Factions? We have a few. Seven Chaos cults, five knightly orders, two mercenary companies, four wealthy families, six (seven!) Corpse Lords, foreign diplomats, rival innkeepers, rival tavern owners, plus all the dungeon-delving gangs currently mucking about underground. When you grow weary of all the adventures at ground level, there are three classic dungeons buried under the city to explore. This book contains months (if not years) of campaigning. Enjoy the Chaos.

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.
