Rogues in Remballo is a city adventure set in Frog God Games' Lost Lands campaign world. As an introduction to adventuring in the Borderland Provinces, the City of Remballo immediately gets first-level characters embroiled in strange plots, sinister intrigue, and fierce battles. Is the thieves’ guild of Manas encroaching on the territory of the Remballo guild? What is hidden in the sanctuary-courtyard known as the Four Corners? How is the powerful banking house of Borgandy involved with all of it? What starts as a straightforward mission actually involves a host of complications — some of which can be deadly if the characters don’t play their cards right.

The dead are all mad in this place. Jaume made the most unfortunate mistake of seducing Ysabel and taking her virginity — a sacrilege for which the sentence was death. Enraged upon finding this out, Joudain cleaved Jaume’s head in two with an axe and then raised him from the dead to continue his duties. Not long afterward, Joudain decided that, because the twin footmen no longer “matched,” he had no choice but to inflict the same fate on Miqèl — who now looks exactly like his older brother. Join them. This heavily revised and greatly expanded deluxe edition of The Cursed Chateau is an adventure for use with Lamentations of the Flame Princess Weird Fantasy Role-Playing and other traditional role-playing games.

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).

Three dungeons in one! The party is given a "dimension shifting device" and sets out to explore a 15-area cave, simultaneously occupied by the DEMON CORSAIRS, the remnants of an ASTEROID MINING OPERATION, and the MONASTERY OF TRANQUILITY & TRANSCENDENCE! The three dungeons are presented in three columns, so when the characters shift from one dimension into another, it's easy to find the corresponding area description. For use with old-school or OSR RPG systems. Recommended for character levels 3-4. Published by Eldritch Fields.

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.

People keep asking for "beginner" dungeons. Everyone can name "classic" dungeons - Tomb of Horrors, Barrier Peaks, Ravenloft, etc. - but in order for those adventures to make sense, there needs to be some sort of introduction. It's like all the adventures we have are Bach concertos. People keep writing amazing works of staggering genius, but someone needs to write a book on how to play the piano. I had the same questions, and since I couldn't find anything satisfactory, I decided to write the kind of dungeon I would have loved to find. I wanted to write the best basic OSR dungeon for beginners that I could, and I also wanted to show the design process. If you like this dungeon, please share it, tell people about it, print copies and leave them lying around local game stores, or email this post to friends who have "always wanted to try D&D but don't know where to start". The entire thing is and always will be free.

Under the Temple Crypt is the first in a series of site-based, Swords & Wizardry** compatible, “micro modules” that can be dropped into just about any campaign (especially a sandbox-style campaign). No underlying story-hook or rationale for exploring the site is given here. This dungeon assumes that there is a temple somewhere with a mysterious walled-in doorframe in the basement crypt. The walled-in doorframe predates the temple itself and leads to ancient subterranean structures that hint of an older civilization as well as an expansive underworld.

A vast, sprawling mega-dungeon beneath the ruins of a nearby castle. Reports have surfaced of stockpiles of wealth within the passages. Regions previously devoid of monsters are reported to teem with renewed activity. Magical and mundane traps have brought foolhardy explorers to their doom. Changes within the passages and chambers have rendered old maps and knowledge dangerously unreliable if not outright useless. To the bold and daring, only one message needs to be heard: the castle and its dungeons are once more ripe for exploration, and new legends are ready to be made. Note: This adventure requires three books for it to be complete (sold as a package): Adventure Book, Map Book, and Illustration Book. Published by BRW Games

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).
