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

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).

Legends tell of a wizard so arrogant that he felt the entire sky was naught but a lens for him to view the stars. So great was the hubris and defiance of this man that the gods smote him with the power of storm and fire. Oh did the wizard laugh at such a pathetic gesture. He did not fear the gods, for he drew his knowledge from something greater. Something darker. The legend of this wizard grew, first whispered by men in fear, and later in awe. The wizard, they said, attacked the gods just as they had attacked him. And his joy only grew as the land around him died. But then there was no more news. No more talk. Something had finally brought the wizard low, for though the sky still blazed down on him and his abode, he no longer blazed back. And now you’re going to walk right through this wizard’s front door.

"Something is weird about this party in 16th century Scotland! A famous thief stole a magical jewel and hid inside a castle where a party is taking place. Enter the party, find the jewel, escape with your life. In the first half of the adventure, the player characters will explore a weird party in search of the thief Jougal. They’ll likely piece together that this party is not “normal” and that this castle is not safe. In the second half, the baobhan sith will reveal themselves, red caps will set the castle on fire, and the PCs will find themselves locked in a burning hellhole. The adventure will likely change from a fun party-crawl into a stressful fight for survival. This is the NIGHTMARE PHASE."

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.

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)

Things are not right at Du Sharid Manor. Months ago, a deranged parish priest and his most devout followers formed a heretical cult.

Once there, the villagers witnessed something terrifying and unexpected. Since the events of that night, the cultists have vanished, but the remaining serfs of Du Sharid now live in constant paranoia. Your party has been hired by the local bishop to to learn the truth about what happened at Du Sharid Manor.

Ages ago, a religious order known as the Druun practiced rituals from inside sacred oak groves, ceremonial pools, and stone henges. In time, the Church of Law and Order suppressed the Druunic teachings, and the ancient holy sites were lost, forgotten, or converted to other uses. One such former site is located in the capital city of Dolmvay in the center of a small neighborhood known as Whiteoak Square. This neighborhood has recently been experiencing a strange phenomenon: At night, small dancing lights have been seen floating throughout the neighborhood. The residents were afraid of this sorcery at first, however, the lights seem to exude a feeling of peace and contentment, and the locals have grown used to them. How it Started: A few weeks ago, a butcher named Walton Brand was clearing out his cellar when he stumbled upon a secret underground passage that led to an ancient Druun hall. This hall was filled with lost relics, arcane lore, and forgotten treasures of the Druun. Walton told his friends, Loomis the Baker and the chandler Stefan of Walsbury, and the three men began sneaking away from their wives at night to dress in Druun finery and pretend to be men of wealth. A harlot named Red Kirsten was hired to attend them as they drank, feasted, and cavorted in the sacred hall. Unbeknownst to the revelers, the Druun hall still retained some of its magical powers and their merriment awakened the ancient guardian spirits of the grove. These creatures, known as faerlings, are the lights that have been seen dancing throughout the neighborhood. The faerlings were given life by the revelers' glee, and they project that joy and happiness onto the other residents of the neighborhood. This glee, however, is about to turn to horror. . . Oak Grove Whispers is a Labyrinth Lord™ adventure designed for 3-6 characters of 1st-3rd levels (about 10 levels total). The adventure is broken up into three chapters that take place in a small neighborhood located in the capital city of Dolmvay (the Labyrinth Lord is free to substitute any medium- to large-sized city from his own campaign world). Oak Grove Whispers involves a mixture of roleplaying, investigation, and dungeon crawling, so a diverse range of classes is recommended. As the adventure is set in a civilized city, the characters must also be careful their interaction with NPCs does not land them on the wrong side of the law. Published by Small Niche Games
