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

The source of this soul-crushing music was tracked to about 90 miles northwest of Ambir. What was found? A massive, oddly built stone tower that wasn't there before. Word quickly spread and the curious set out in droves. Many turned back however, as every passing day the music got worse, but a brave, or foolish few, managed to make camp and eventually go inside. If anyone's made it out, no one really knows, but there's no shortage of rumors as to what's really going on in the place that's come to be known as, Sision Tower.

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.

‘Wyrd’ things are afoot. This town might seem like your ordinary, post-apocalyptic-now-turned-fantasy locale, but it is not! Fell Cults have begun to take over and it is up to the brave adventurers to stop one in particular: the Cult of the Shield Ghul. But the ‘Wyrdness’ doesn’t end there. Though this adventure can be used to facilitate your typical wander-around-and-kill-everyone-to-take-their-stuff-type scenario, it also includes a sinister (and frankly genius) plot, feuding factions, plenty of hyphens, not to mention bizarre NPC’s and situations to either interact with or stab to death.

A level 1–3 dungeon adventure by Giuseppe Rotondo. The secret workshop of a long-dead jeweler-magician is now open, as his grandson wants the place finally cleared of all dangers. What treasures might remain within, and what might be watching over them? This adventure combines classic dungeon crawl elements with the intrigue of uncovering a magician’s legacy, making it a rich experience for both new and seasoned players. For Old-School Essentials (OSE) Included as one of four adventures in "Old-School Essentials Adventure Anthology 1"

The adventure takes players from a town devastated by an unexpected flood, through a drowned land where nature is turned upside down and desperate families cling to the roofs of their ruined homes, hiding from the monstrous products of a disordered world, through the strange tomb of an ancient race, to a profundal zone, hidden for millennia and now exposed, and finally to the Observatory itself, an eerie abandoned treasure palace, where they will encounter a pale and unexpected terror which will seek to claim their lives. The adventure is suitable for a lucky mid-range party, a stupid high-level party or an exceedingly clever low level party. It is difficult, with a meaningful possibility of character death. Should you find them, and defeat their guardians, the treasures of an ancient culture will be yours. At the final point of the Observatory is a glimpse of another world.

Your party approaches a barrow at the base of the mountain. A raging storm brews overhead, and as you approach, a bolt of lightning strikes down on the peak of the mound, lighting up the world all around you. A thunderclap momentarily deafens you, and as your eyes adjust to the resuming grey of the dark day, you see a flicker of firelight emerging from the two gaping holes built into the side of the hill. You’ve found the pirates camping within the Barrow of the Raging Storm. As I delivered it to my players, the premise of this Midnight Sun adventure is that some pirates have been attacking ships returning from raids. They have been stealing the loot and the corpses of any slain Nords. Among their victims, a ship from Valthis returns to tell them that the pirates sailed upriver (to hex 506), where I placed the Barrow in my Shadowdark RPG campaign. The adventurers started from there and explored the dungeon thoroughly. The adventure was created using the tools described in the Shadowdark RPG core rules. I created it in about 6 hours between 2024-03-08 and 2024-03-09 and ran it for my group on the 9th. It took about 2.25 hours to play to completion. The party consisted of two level 1 characters and one level 2 character. I had so much fun making and running this that I will continue creating more Midnight Sun Adventures, so stay tuned!

Under the Temple Crypt is the first in a series of site-based, Swords & Wizardry** compatible, “micro modules” that can be dropped into just about any campaign (especially a sandbox-style campaign). No underlying story-hook or rationale for exploring the site is given here. This dungeon assumes that there is a temple somewhere with a mysterious walled-in doorframe in the basement crypt. The walled-in doorframe predates the temple itself and leads to ancient subterranean structures that hint of an older civilization as well as an expansive underworld.
