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).

In such a case, the DM is encouraged to expand, revise, and delete as necessary.

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

"Come on," they said, "It won't be so tough, just stopping a slavery ring," they said. "I don't know," you said. "Those slaves aren't even entirely human! How do we know they won't try to kill us?"

There have been disturbing signs over the last few months, signalling that something is wrong in Humblewood. The troubles appear to originate from activity in the Scorched Grove, an ashen plain that was ravaged many centuries ago by a destructive fire. Whatever caused the fire has scarred the land with elemental magic, making it inhospitable to all but strange fire-based creatures. Of late, the Grove has begun to expand. At first, it was hard to notice the slow expansion, but those in tune with nature (especially the Tenders) could see the imbalance in the elemental forces of Humblewood. For many common folk, this imbalance has been experienced as unseasonal dryness, which has led to crop failure and an increased frequency of forest fires. There have also been a number of unusually aggressive emberbat clouds reported far outside of their natural ranges. The true nature of the danger still remains hidden from the people of the Wood. A corvum necromancer named Odwald Ebonhart has stirred the elemental aspect of fire, which has lain dormant beneath the Scorched Grove since its first burning. The aspect’s energies have begun to empower fire-based creatures within the Wood. The increased range of emberbat swarms have brought fires that have expanded the Grove. Many forest-dwellers, who have been left without homes, have turned to banditry to survive. Soon the elemental incarnation will break free, and players must find a way to stop the aspect of fire before it reduces the Wood to ashes.

The Noble Rot is a location-based adventure for characters of 5th to 8th level. This adventure can be played in one or two sessions of reasonable length. It is a straightforward, haunted house-style adventure. The story revolves around Le Chateau Gluant, a vineyard and winery of repute. Vintages of its famous white (chardonnay) and red blend (cabernet sauvignon) are sought throughout the land. Some vintages can bring up to 200 gp per bottle from the right buyer. A case (twelve bottles) of the wine in pristine condition can fetch up to 1,500 gp. Unfortunately, the winery fell upon dark days and the prized wine has not flowed from its cellars for a few years. Approximately five years ago, the head winemaker, Malcolm Roth, hired Tobias Suey as an apprentice. Unfortunately for Roth, Suey was a member of the Cultus Limus (Cult of the Ooze). The Cultus Limus makes sacrifices to its demonic master Lumaszu in her faceless form. Lumaszu or “she who erases” is an ancient demoness who preys upon travelers by drinking their blood. She is the cause of nightmares, pestilence, infestation of pure water, and a bringer of disease, sickness, and death. Her worshipped form in Cultus Limus is that of a gigantic ooze. Suey turned the field hands who tended the vines against the winemaker. Then the new cult turned its attention to the Gluant family. Eventually the cult members started preying on each other. With each sacrifice to the ooze, Suey’s power grew—until there was no one left but Suey. The whim of demons is fickle. Suey was blighted and corrupted for his work. Now he deep in the cellars under the chateau as a minor ooze demon. His handiwork, however, remains. The chateau is now the abode of its former residents and workers, in undead form. Also slimes, molds, fungi, and other foulness fester in the fields, buildings, and cellars. The riches of the Gluant family remain undisturbed; would-be thieves and robbers quickly fall prey to the current residents. Besides normal valuables, cases of wine remain undisturbed and waiting to be plundered. The title The Noble Rot refers to a few factors in this adventure. The first is the rot that befell the Gluant family in the form of the Cultus Limus. Another is actual noble rot disease that may aid the PCs in overcoming the challenges posed. The phrase also refers to a real-world gray fungus, Botrytis cinerea, which in the right conditions creates world-class dessert wines such as French sauternes. In the wrong conditions, it destroys grapes and is known as gray rot.
