A centuries old evil has been cultivating an environmental disaster deep under the earth, waiting for the time when it will be unleashed on the world. A new mine has been created above and has broken the seal. The owner of the mine has lost contact with their foreman and shipments have stopped, and it’s up to an inexperienced but eager group of adventurers to investigate. This adventure is designed to present a challenge for a group of four veteran players using first level characters. While there are opportunities for roleplay scattered throughout, this adventure is heavy on the exploration and combat pillars of fifth edition. Death is a real and ever-present threat as they investigate the mine and the dangers below. Success and survival should bring them to the third level, and they may have found some treasure well worth the effort. So much so that they may become targets themselves from unscrupulous and more experienced NPCs. Written to be a seed for a larger campaign in any high fantasy setting, the outcome of this adventure could have world-changing consequences. It introduces a new and growing threat that, given enough encouragement, greed, time and apathy, could consume the world and beyond.

Many centuries ago, a band of paladins fell from grace. These blackguards were defeated after a great battle and their grim fortress, the Iron Tower, was razed. A small abbey was established near the ruins, where generations of monks mixed ancient eldritch wards, mighty clockwork traps, and multiple fail safes to build the Iron Crypt of the Heretics. Three mighty vaults ensured that its evils would be sealed for all eternity. But unbeknownst to the brotherhood, their impregnable crypt had a single weakness: the very monks that had built it, for they knew its secrets. When a devourer stole into their abbey, the profane beast forced the monks to help it inside the Iron Crypt. It successfully broke into the first of three vaults, releasing an army of wights. The story of the devourer and his wight army is told in Dungeon Crawl Classics #12: The Blackguard’s Revenge. Now, in the Iron Crypt of the Heretics, the heroes must venture into a crypt designed by the world’s greatest thieves, magicians, and seers, solve its puzzles and deadly traps, and seal it once more from the outside world.

Tired and sore, you struggle over the burning sands toward the long-forgotten city. Will you reach the place in time to save yourselves from the evil efreeti? The sun beats down, making your wounds stiff and worsening the constant thirst that plagues anyone who travels these waterless wastes. But there is hope - are those the ruins over there? In the midst of broken columns and bits of rubble stands a huge statue. This is the place! You've found it at last. Gratefully, you sink onto the sand. But there is no time to lose. You must hurry. So with a quavering voice you say the magic words. And then you wait... A hush falls over the ruins, making the back of your neck prickle. Then, out of the east, a wind rises, gentle at first but quickly growing stronger and wilder, until it tears at your clothes and nearly lifts you off your feet. The once clear sky is choked with white and grey clouds that clash and boil. As the clouds blacken day turns to night. Lightning flashes followed by a menacing growl of thunder. You are beginning to wonder if you should seek shelter, when all of a sudden there is a blinding crash and a bolt of lightning reduces the statue to dust. For a moment, silence. The, out of the statue's remains, soars a blue flame. Its roar deafens you as higher and higher it climbs, until it seems about to reach the clouds. Just when you think it can grow no larger, its shape begins to change. The edges billow and soften, their roar lessens, and before your eyes materializes a gigantic blue man. This adventure can be played alone or as the second part of the Desert of Desolation series. For characters level 6-8. TSR 9053

The Dread tunnels of Ruxbar were created by a cult of a lesser evil deity of the giant pantheon, known as Jargain to serve as a planar gate in hope of bringing chaos and destruction to the natural order of the world and power to the one who would control the gate.

For some time the gate remained open and the settlements nearby were afflicted with diseases never seen before. The nearby town of Stagwood was quickly abandoned due to the plague. Rumor has it that the gods have weakened the gate and the cult has been destroyed. The remaining villages that managed to somewhat resist the plague are now hiring brave adventurers to venture into the tunnels and close the planar gate for good! Are you capable enough of surviving the horrors that reside in the Dreaded Tunnels of Ruxabar? Published by Mistfactor Press
