The adventure takes players from a town devastated by an unexpected flood, through a drowned land where nature is turned upside down and desperate families cling to the roofs of their ruined homes, hiding from the monstrous products of a disordered world, through the strange tomb of an ancient race, to a profundal zone, hidden for millennia and now exposed, and finally to the Observatory itself, an eerie abandoned treasure palace, where they will encounter a pale and unexpected terror which will seek to claim their lives. The adventure is suitable for a lucky mid-range party, a stupid high-level party or an exceedingly clever low level party. It is difficult, with a meaningful possibility of character death. Should you find them, and defeat their guardians, the treasures of an ancient culture will be yours. At the final point of the Observatory is a glimpse of another world.

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.

Standing 100 feet off the shores of the vast Sapphire Lake are the ruins of a small fortress standing atop a rocky islet. The fortress belonged to a lich posing as a warlord from the Kingdom of Old Hagada, but fell rapidly into ruin when the Shrouded Hero was able to pierce the lich with the Blade of Five Seals. The lich cursed the assassin and his incompetent guards with his final breath. He cursed them to the same fate, their bodies petrifying and all of their souls being sealed in the Sheath of Five Seals. Afterwards, the warlord’s armies were defeated on the battlefield and the fortress became abandoned. In this short 3rd level dungeon crawl, the party investigate a ruined island fortress to solve a mysterious puzzle box. You can run this as a one-shot or plop this into your campaign world with minimal effort. The adventure is designed for Shadowdark RPG and references the core rulebook. If you're an experienced game master, you could convert the adventure to whatever system you prefer.

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.

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).
