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).

(EQ1) The Cursed Ring is a generic fantasy short adventure for low-level players, themed around puzzle hunting, traps, and monster combat. It is designed to be solved in approximately 5-6 hours, depending on the size of the party and skill of the players.

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.

She used to roam the high seas, destroying ships and devouring everything. Some of the people she swallowed survived in her belly. One of them, the sailor Torsti Seppänen, actually managed to turn the place into a comfortable habitat. One day, Gargantuel passed away. Her body now lies out in the open, luring the carrion-eater, the curious, the foolish.

The Dark Tower A Worlds Without Number Compatible Adventure The adventure is set up so the Player Characters [PCs] can encounter diverse types of situations and different adventure styles, allowing for role-playing within a rural situation, with wandering monsters, and a dungeon/Deep encounter. The module offers a chance for the GM to immerse themselves and their players with as much, or little, detail as they want to put in. Rolling countryside surrounds The Dark Tower for miles. Giving you, the GM, the opportunity to fit the adventure into almost any setting within your game. I have left the ending open, allowing the GM to slot in further encounters or adventure twists to keep the game moving but with enough happening to turn it into more than one session if so desired. The Plot There are several options for the plot: A local innkeeper would like you to investigate the haunted tower on the hill. He is willing to offer a good reward. A local village Elder could ask the PCs to seek out/investigate/destroy the walking dead that have been seen around the tower. Please investigate the tower to see if the rumors are true. A Local priest would like the PCs to remove the possible undead worrying the locals from the tower.

Your party approaches a barrow at the base of the mountain. A raging storm brews overhead, and as you approach, a bolt of lightning strikes down on the peak of the mound, lighting up the world all around you. A thunderclap momentarily deafens you, and as your eyes adjust to the resuming grey of the dark day, you see a flicker of firelight emerging from the two gaping holes built into the side of the hill. You’ve found the pirates camping within the Barrow of the Raging Storm. As I delivered it to my players, the premise of this Midnight Sun adventure is that some pirates have been attacking ships returning from raids. They have been stealing the loot and the corpses of any slain Nords. Among their victims, a ship from Valthis returns to tell them that the pirates sailed upriver (to hex 506), where I placed the Barrow in my Shadowdark RPG campaign. The adventurers started from there and explored the dungeon thoroughly. The adventure was created using the tools described in the Shadowdark RPG core rules. I created it in about 6 hours between 2024-03-08 and 2024-03-09 and ran it for my group on the 9th. It took about 2.25 hours to play to completion. The party consisted of two level 1 characters and one level 2 character. I had so much fun making and running this that I will continue creating more Midnight Sun Adventures, so stay tuned!
