The abandoned Tower of Ulvarum Orvernus stands atop an asteroid nearly a quarter mile in diameter, located roughly 5 million miles from the planet’s surface. The asteroid maintains Earth-like gravity and a breathable atmosphere, with habitable temperatures. This is all sustained through the harnessed power of a bound Air Elemental and Earth Elemental. If either of these Elementals are freed, the asteroid’s environment will quickly become inhospitable. The PCs may find themselves drawn to the asteroid through a forgotten portal, seeking a way to return home. Alternatively, they might be lured there by rumors of a powerful item or hidden knowledge within the tower’s extensive libraries. A multi-level tower filled with traps and strange encounters including animated armor, alien plant life, giant spiders, and a doppelganger.

An adventure in Hyperborea designed for from four to six characters of 7th through 9th level Your party finds itself in the employ of Ragnarr the Sea-Wolf, a jarl of New Vinland and a reaver of old. His daughter, a shield-maiden named Gunnhildr, has been abducted by a brute called Björn Blackbeard. During a desperate search, the Sea-Wolf crossed sails with a former rival, and from the blood-flecked lips of a dying foe, he learnt the location of Blackbeard’s stronghold. Now, deep in the misty fjords of Brigand’s Bay, where cutthroats, pirates, and freebooters thrive, you have been charged with liberating the Sea-Wolf’s daughter. The Sea-Wolf's Daughter takes players into an action-packed realm of adventure: the mythical world of Hyperborea, a sword-and-sorcery campaign setting inspired by the fantastic fiction of Robert E. Howard, H.P. Lovecraft, Clark Ashton Smith, and others. This adventure is designed for Astonishing Swordsmen & Sorcerers of Hyperborea™ (AS&SH™), a role-playing game descended from the original 1974 fantasy wargame and miniatures campaign rules as conceived by E. Gary Gygax and Dave Arneson. Therefore, AS&SH is compatible with most traditional fantasy role-playing games (c. 1974 to 1999) and their modern simulacra, such as OSRIC™ and Swords & Wizardry™.

Dreams of the sleeping wizard seep into reality. Manifest familiars war over the fate of a remote islet. An infinite garden houses an escaped experiment. The god of purity is fooled for his blessings. Into the nightmare we go. 16 pages contain 3000+ words describing 10+ keyed areas to explore (complete the wandering monsters table), 10+ friends and foes to talk to, 10 magic items to use, and thousands of gold worth of treasure to plunder. The adventure is designed for B/X, or like-systems. It is suitable for 4 to 6 characters of levels 1 to 3. It is heavily inspired by the dungeon synth album The Sleeping Wizard by Umbría, which may serve as a soundtrack.

The Dreaming Caldera involves the players infiltrating a volcano teeming with monsters that are intent on constructing a chaos god. The players must navigate through the hostile environment, disrupt the monstrous activities, and ultimately prevent a catastrophic event. 27 keyed locations Written for the Old-School Essentials (OSE) rule system

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.

This scenario was originally written for use as a competition event at Games Day 1987. We have published the adventure so that you will be able to reproduce the competition. The scenario also serves as an introduction to the forthcoming supplement detailing the land of Lustria. (see WFRP World Map, p272). At Games Day the party had to play the part of a small band of pygmies, and we have included details of this party so that you can use them too. You should carefully read the notes on Witchdoctors, Ancestor Spirits and the spell Control Spirits before starting play. If a conventional party is used here there is a significant chance that players will lose favourite characters. Much of the scenario is geared towards pygmies, (some tunnel heights, the presence of pygmy ancestors and so on), and a party without access to pygmy-magic may find some areas extremely difficult.

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).

This setting blends sci-fi and fantasy with a touch of the absurd, offering a playground for imaginative gameplay and storytelling.

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!

In Claine Forest near Padduck Village there has appeared a pit. No-one knows where it came from, it just did. It is not so deep that you cannot see the bottom, but people fear it and avoid it. No-one who has climbed into it has come back, having been dragged beneath the surface by unseen hands. A necromancer has come to the forest, seeking the pit. She does not quite know what she expects from it, but what she hopes for is protection from death. Player-characters may wish to get involved, and thus this constitutes an adventure for old-school systems, for 5-6 PCs of 2nd level 2 or slightly fewer of 3rd. The PCs won’t necessarily all die, and the players will almost certainly survive. Reviews elsewhere: "It pours out flavour in nearly every word, creating delicious situations for the party to interact with. ... We got a village, two rival groups of adventurers, a weird-ass forest, and somewhere in the forest a pit, your final destination. From this, joy is made. Each one of those elements has their component parts well done and, because of this the whole is a wonder." — Bryce Lynch of tenfootpole

Those friendly dwarves were the first to go, the poor things. And now the beast has been killing and eating the people of Brandonsford. No-one wants to leave the town's walls. With the humans out of the forest, fairies have taken over, and now the goblin king Hogboon seeks to claim the entire forest as his new kingdom.

Strange doings are underfoot in the wild hills bordering the realm of decent and civilized folks. Villagers and cattle have gone missing; woodcutters have disappeared; misshapen beings have been seen shuffling through the forests. Some brave villagers have tracked a group of stolen oxen as far as the rocky banks of a small river in the hills. The trail disappeared down into a fissure in the limestone rock, where a fast-running stream plunges down to the dark caverns below. Gird your loins, stand behind the dwarf, and get ready to face The Pod-Caverns of the Sinister Shroom!

Establishing themselves in the cyst left by their dead god, a zealot band of Shrooms, a race known for bizarre projects and subtle objectives, have been working for decades on the strangest task in their strange history. They are growing themselves a new god.
