One page adventure, one page map. On the edge of a lake/ocean’s windswept field/forest, outside of his small stone home, a very old, callous human magic user, Cyfrin the Wrathful, summoned an invisible stalker in a magical binding circle. First he began to taunt the stalker, proclaiming his dominance over it, describing its powerlessness to do anything but carry out the old spell caster’s will. Next, Cyfrin dispelled its invisibility, ordering it to execute his plan. In Cyfrin’s excitement, he gazed upon the stalker’s now visible, horrifically impossible face - and abruptly suffered a stroke, dying on the spot. Still imprisoned, the stalker wants freedom. Will the PCs help it? Adventure hooks provided. Published by Wicked Cool Games

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

Terror roams the dark and brambled paths of the Kryptwood. A pack of giant spectral hounds rule the night, savaging those foolish enough to brave the forest. The villagers of Hendenburgh cower in the shadows of the ancient boughs as each morning heralds a newly savaged corpse. Explore the ancient paths of the Kryptwood in a 25-hex hexcrawl. Discover the mysterious Tyrant's Tomb. Negotiate, serve or betray the factions of the Kryptwood (a ghostly despot, a gang of highwaymen with excellent PR, a horrifying witch coven, and the eccentric inhabitants of Hendenburgh). Fight new monsters such as owlboars, kryptwood hounds and ghostly tyrants. Hounds of Hendenburgh is designed for use with Cairn by Yochai Gal but compatible with other OSR systems. If using OSRIC, OSE or other OSR rulesets then the adventure is best suited to low-level parties (1-3). Reviews Hounds of Hendenburgh is an adventure brimming with potential energy, like a domino run—any prodding by the players is sure to set off a chain reaction, but where any individual piece will end up is anyone’s guess . . . For me, Hounds of Hendenburgh is a major highlight of A Town, A Forest, A Dungeon. I’m eager to bring it to the table, and I expect it’s the sort of adventure that will reward referees who run it multiple times. - Dododecahedron Blog This 22 page adventure presents a delightful little romp through a colourful town, a dreadful forest, and a small haunted dungeon/crypt. Would that everything I reviewed were at least this good. A credit to county Donegal! - Bryce Lynch (tenfootpole.org)

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).
