Long ago, a ruthless queen fell to the power of the magocracy, who barely stopped the rise of her cult.
But their victory was incomplete — and now her fanatical followers have performed the final rite.
Resurrected using a sacred, dark and forbidden ritual, she also boosted her powers even further by a secret pact,
she has returned to the Prime Material Plane… seeking retribution and chaos.
Who will stand in her way?
Why you should run Crimson Conspiracy as your next adventure
Crimson Conspiracy is a sweeping 5e campaign where players start as epic heroes of old, fighting their way through an epic high fantasy dungeon where they know the odds are impossible. But all is not lost, if they can buy enough time, the fate of the world may be saved from ultimate doom. In chapter 2, players begin anew as inexperienced adventurers — the grandchildren of the heroes who once failed to stop the Queen’s ritual. Now, her cult has risen again, stronger, darker, and blessed with fiendish power.
Players will flee across the countryside, uncover secret cells of the cult, gather allies, grow from low-level wanderers into veteran champions, and ultimately face the resurrected Queen herself.
This campaign blends intrigue, travel, frontier tension, city politics, wilderness threats, Underdark expeditions, and full infernal warfare into a single epic journey.
Epic Encounters Unlike Anything You’ve Faced Before
Prepare for battles and challenges that redefine the limits of roleplaying. Face an ancient red dragon whose fury alone could reduce kingdoms to ash. Navigate life-threatening traps that will test both your wits and your dice rolls. Survive an underground lava chamber where time itself is your enemy. Every encounter in Crimson Conspiracy is crafted to be a cinematic, high-stakes event that will leave your party breathless.
What makes Crimson Conspiracy stand apart? You don’t just play through the module—you define the course of history. Will you rally as noble heroes, fighting to save the world from utter destruction? Or will you take a darker path, aiding the Keepers of the Crimson Flame in their sinister quest and ascending as champions of chaos? The choice is yours, and every decision shapes the fate of the world.

Meet the Team
For over two and a half years now we have been writing, developing, and play testing our Dungeons and Dragons campaign, Crimson Conspiracy, in parallel with the other projects set in our world, Athalus Dvarrus: The World of Gateways.
As an avid DnD player since 1978, scarcely a week has gone by that didn’t involve DnD in some manner or another. My focus with Crimson Conspiracy has been ensuring that the massive amount of material we have been writing and developing is truly unique. A refreshing DnD campaign awash with in-depth story telling and impactful player decision making. Ensuring that all of our material focuses on and celebrates its OSR roots, aesthetics, and art—emulsified in a fresh new approach for 5e and 5.5e.
In true Fallen Dominion Studios fashion, the Crimson Conspiracy campaign will be talked about for years to come by your game group. We pride ourselves in our exceptional forethought for both our DMs and players, all with the exceptional quality our fans have come to expect from all of our products.
We have every intention on releasing Crimson Conspiracy for our favorite DnD adjacent OSR systems like DCC and Shadowdark, as we want everyone, to experience the many ways this DnD campaign stands out from all others.

Crimson Conspiracy and the Al’Duress campaign setting have and continue to be a love letter to everything I have ever experienced or wanted to experience in roleplaying games. We focused on the ‘bucketlist’ of things that we wanted to do in a dungeon or role playing event, and from there a story was born.
I know you are going to enjoy this and I look forward to the buzz that it generates. We have already received rave reviews and our excitement has only built from there!
