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

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.

The carcass of a gigantic sea monster is now a small dungeon... Gargantuel was a gigantic sea monster (a whale? a prehistoric serpent? the Kraken? Leviathan itself?). She used to roam the high seas, destroying ships and devouring everything. Some of the people she swallowed survived in her belly. One of them, the sailor Torsti Seppänen, actually managed to turn the place into a comfortable habitat. One day, Gargantuel passed away. Her body now lies out in the open, luring the carrion-eater, the curious, the foolish. Strange creatures and artifacts await in the mounds of decaying flesh, and the insane Torsti Seppänen will do everything to defend his “home” from intruders. Statted for Lamentations of the Flame Princess, usable with any OSR type game. Hosted by eldritchfields.blogspot.com

Precis Intermedia brings back this follow-up to the first known commercially-published adventure (Palace of the Vampire Queen) for the original Roleplaying Game (First Edition/OD&D/0E). Originally released in 1977 by Wee Warriors, The Dwarven Glory provides 8* map sections that can be arranged as desired and containing pre-factored creatures and treasures (in other words, this is essentially a geomorphic stocked dungeon). While hit points are provided for the creatures, the First Edition RPG or an OSR equivalent (B/X recommended) is required for actual rules and their descriptions. At one time, the community of Dwarven Glory was a thriving and wealthy one. The community became easy prey for Mortoc and his Ten Orc Tribes. Although the Orcs conquered Dwarven Glory, they could not completely destroy it. There were parts of the caverns they did not even penetrate. Now the caverns echo in the misty gloom, offering refuge to the forgotten and promise to the adventurer. This piece of gaming history is a must for collectors and old school gamers. With the original on the extremely rare list, this classic reprint of The Dwarven Glory has been remastered for a clean print, and is readily available at a low cost. * The original printing included only 7 map sections, designated Sections B through H. The mythical Section A has been added as a bonus. Wee Warriors and The Dwarven Glory are trademarks of Precis Intermedia. All rights reserved.

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

"You have been hired by a secretive council of wizards, who refuse to meet in person with you, to rescue the survivors of Mugwort - a town which was thought to have been destroyed and lies deep within The Toxic Wood.

Under Mirt’s Folly is a 200+ location mega-dungeon from Dunromin University Press Mirt the Long Flame was a mighty wizard a hundred years ago. He fell in love, so the story goes, with a beautiful Goddess. Using all his powers he built his true-love a temple and a pleasure palace with the intention of making her his wife. On midsummer’s eve he bent all his powers to calling her down from Olympus, luring her to our world with the sweetest compliments and tempting gifts. After several hours of calling she appeared and he proposed to her, explaining the wonderful life together he had planned for them. She was not amused. The blasted remains of the temple and the derelict palace, all made from the finest white marble, are all that remains of Mirt’s crazy ambitions. The abandoned ruins are now known by all as Mirt’s Folly. Of course, the anger of a mighty Goddess leaves deep scars in the landscape. A hundred years later the hill, despite being in civilised lands, remains an abandoned place of strange magic. It is the haunt of ghosts and monsters and all who go there return changed, fearful and anxious, if they return at all. No one knows the nature of the Curse of Mirt’s Folly and few desire to find out. But Mirt was a great mage! His powerful magic items and his many books of spells and research have never been found, not to mention the vast wealth he had accumulated.

An adventure in Hyperborea designed for from four to six characters of 6th through 8th level In the far reaches of Hyperborea’s Crab Archipelago lies a small, mountainous island known as Crystal Point. Passing sailors recently have witnessed a crimson glow in Crystal Point’s waters and beams of russet light shining up from its steep cliffs. Too, unusually frequent lightning storms in the area have torn the sky in blinding flashes, shattering the air with their awesome sound. The seedy wharf taverns of Khromarium and elsewhere buzz with these strange tales—some even speculate that Crystal Point may hold the lost treasure of Atlantis!

Howard, H.P. Lovecraft, Clark Ashton Smith, and others.
