England, 1620. To strike a blow against the Patriarchy, six women perform a dangerous rite in an abandoned priory.  Through dance, they commune with Terpsichore, Greek muse and patroness of dancers. Starving demons slither across the moors; monstrous nuns shriek in the infirmary; and within the Attic, a great unraveling awaits. The fate of the world rests in the hands of the players. Will they bring about an egalitarian utopia? Will they skulk away in the night, pockets bulging with treasure? Will they bring about the destruction of all things? Will they find the Tract of Teratology, a randomly-generated creature-summoning ritual with 3.6 quadrillion combinations? After this adventure, nothing will be the same. An adventure for Lamentations of the Flame Princess Weird Fantasy Role-Playing and other traditional role-playing 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).

This morning, the forces of Law and Chaos clashed at Castle Yennagor. The battle raged all day, but as darkness fell, a cataclysmic explosion destroyed most of the castle and leveled both armies.

And one question remains unanswered: what happened inside the castle? This is a dark sandbox adventure. Players take the role of battlefield survivors. They can choose which side they are on (or neither), and they can choose their goal, such as to escape the field with their lives, to plunder the dead, or to reach the castle and finish the mission.

A Gritty OSR Fantasy Setting by Travis Legge The mortal lands are divided. A dozen kingdoms lie scattered across the world, separated by dangerous wilds filled with bandits and monsters. The bravest mortals act as adventurers, guiding travelers between the kingdoms, killing monsters to thin their numbers, and plundering ruins in search of the lost treasures of the golden age. This is the world of Odysseys & Overlords! The party are traveling west through the Untamed Gauntlet, on their way to somewhere else and using a stream to guide their steps. They step out from under the eaves of the forest to spy looming before them a cliff, a tall wall of stone which stretches away to either side as far as they can see. A waterfall cascades onto sharp rocks into a pool from which pours the stream they were following. The sheer cliff is easily 100 feet high, and too wet and slick to climb safely, though it can be tried. Atop the cliff is a bare stone hill which looks like it was at one time worked by intelligent hands; a look-out post of sorts has been carved into its southernmost peak. The map says it’s called “Wyvernseeker Rock,” but it doesn’t say why. The hill appears deserted. A long age ago, beyond mortal memory, a forgotten people built a watching post and refuge atop and within Wyvernseeker Rock. A hundred years ago, an adventurer named Olaf Wyvernseeker claimed the Rock for his own and set out with companions to clear the lands thereabouts. They were never heard from again. The upper chambers of the Rock are a convenient lair for a Giant Rhadogessa and its spider servants. Still, it’s got to be safer than climbing the cliff. Right? Published by Aegis Studios

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.
