The lost city of Archaia - an ancient ruin sunken into the earth - lies deep in the badlands. In recent years, caravans from Eastdale have come under attack from orcs, goblins, and worse. Some say these blood-thirsty warbands have made lairs in the deep caves and ruins. Sill others say the ancient halls are filled with magnificent treasures left by the Archaians. Are you brave (or foolish) enough to delve The Forbidden Caverns of Archaia? The Forbidden Caverns of Archaia (FCoA) is a 296-page classic megadungeon for use with any old school fantasy role-playing game. The pages of Forbidden Caverns are crammed full with new material, maps, amazing art (including special surprizes by former TSR artists), as well as an amazing colour cover art by Ex-TSR artist Erol Otus that matches Barrowmaze Complete as a sister-book. The Forbidden Caverns of Archaia will keep your players on their toes and your campaign going strong for years. FCoA is brought to you by the Old School Renaissance (so don’t forget your 10’ pole).

Something fell. A sickly gloaming lit up the night like mock daylight, just for a moment, and then the hills trembled. Now, an alien entity lies brooding in a crater gouged out of the moor. Local folk are enraptured with the toothsome jelly exuded by this being, but are blind to the true nature of the events unfolding in their rustic little backwater.

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!

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!

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).

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.

A level 2–3 sewer adventure by Glynn Seal. PCs plumb fetid sewers and recently-revealed secret halls, in search of a lost worker.

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.

Long ago the dwarf-like "Dverg" established a "forge" hidden deep beneath the earth where they forged weapons of "cold" iron. Cold iron was considered a far superior material and was especially effective against Trolls and could even damage ghosts.

Among them is rumored to be the fabled Axe of Mortality - a weapon said to be powerful enough to slay a god. Is your party brave enough to venture out in search of these valuables?
