A dungeon of tricky puzzles, ancient magical secrets, and more than a few lingering mysteries, designed to be played as a standalone adventure and not incorporated into another campaign. Six adventurers descend into the Temple of Mysteries to find a mystical artifact called the Strand of Tears. Seems straightforward enough, except that some of the party may not be who they say they are. In fact, none of the party may be who they say they are. Not only that, but they might not be who they don't say they are, either! Worst of all, they're trapped in the ruins of an underground temple specifically designed to keep people from proceeding unless they're proficient in puzzle-solving...and there may be doppelgangers on the loose.

"Deeptown lies in the shadow of mountains, a town where anything is for sale if you can only meet the price. But in the wild surrounding valleys of the Deeps, it's the bandits who make the darkest deals - and their ambition comes at a cost far greater than the contents of any wayward caravan. You and your team have just been handed a new job: disrupt a meeting between a bandit lord and his mysterious new allies. At a remote mountain villa, you will strike hard and fast and leave terror in your wake. They give you the tools. You provide the talent. Survive, and you'll be well rewarded. Fail, and you'll pay the price. You've got three days to raise some hell." This was one of the first third party adventures under the OGL for 3rd edition published by Atlas Games under the Penumbra line.

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
