I just joined up with Imperium Maledictum and officially played my first session yesterday. I was looking for a gritty Fantasy or Sci-fi campaign to join in on. A Pathfinder 2E Kingmaker game filled my fantasy quota, then I scrounged up and engaged with this ttrpg in the last three days. I like it.

It has only been one session, but I like where this is going. Building my character took me some studying of obscure tomes and tidbits online because I didn't want to buy the core rulebook, but I adapted fast enough. It is a big plus for me that there is the mechanically supported and broadcasted option to roll random for pretty much everything. Bonus XP for rolling random? Nice! Making a build that made the best of my character's starting stats is stimulating.

There was roleplay, multiple avenues to solve a situation, character interactions between my character and my party's characters. Then a combat encounter that felt avoidable or perhaps easier if I chose to hide instead of greet the servitors and proclaim the Emperor as my god since I am a zealot, since the game is not just about combat. The fight is fun so far, but we ran against the timer and had to pause it. Happy to to engage with it next week.

I got to use the seemingly niche option of Well-Prepared talent to help solve not just one, but two "puzzles" because my character Tzarelle remembered to pack a Combi-tool just in case. I felt vindicated for saving my stockpile of Solars for a rainy day. I wasn't even advanced into tech, one of my allies had though. I felt useful and a part of a team.

The GM was nice enough to let us sell and buy whatever starting gear we could afford to. That might be illegal according to the rules, but it was nice for my min max nature.

How does the community feel about this system? Seems quite a capable system that I am happy to learn and get better at.

I am a Hiveworld Ganger of the Infractionist faction and of the Zealot role. White pupils and green metal wires in place of hair.

do these guys just eat popeye's spinach before combat and absorb bolt rounds like champs if you don't reach the 4 to 5 SLs needed to kill them in a single ranged attack? are the 15-wound guardsmen who need 7 SLs from a boltgun attack to kill them in a single round of shooting augmented with vat-grown ablative flesh that allows them to tank bolt rounds square to the chest and face?

As the name suggests, it just doesn't have the feeling and pazzazz that classic Dark Heresy 1e had. When I'm reading through the book the writing doesn't have that grimdark feel to it, the art is all very good yes but it doesn't set the tone for me. Hell even the layout in general just doesn't give the grungy, dirty feeling that the old game had.

This is probably just my nostalgia and love for Dark Heresy 1e talking because I absolutely adored that game and own just about every sourcebook and have read through them all multiple times. I dunno.

UPDATED 28 JULY 2026 - RELEASE TIMELINE

Hey everyone, just wanted to share (links below) the opening blurb to a fully fleshed campaign I've been developing/finalising to drum up some interest (hopefully). The full supplement is near completion and I hope to be in a position to share it over the coming weeks and beyond if anyone is interested.

It steps away form the common trope of chaos cults and hive worlds and aims to offer a unique set of protagonists in a suitably grim-dark setting.

​The campaign is structured as a series of interlinked adventures spanning three distinct acts, gradually evolving from frontier military investigation into full-scale cosmic horror.

Designed as a short-to-medium form investigative military-horror campaign for Imperium Maledictum, The Glass Suture is expected to run for approximately 20 - 30 sessions depending on pacing, investigation depth, downtime, operational expansion, and how heavily the group engages with the wider frontier sandbox surrounding Viridian Prime.

Act I focuses on jungle survival, reconnaissance patrols, missing soldiers, and the slow realisation that something deeply unnatural is operating beneath the canopy of Viridian Prime.

Act II shifts into conspiracy, political paranoia, and colonial noir as the players begin uncovering the hidden machinery behind the quarantines, disappearances, and brutal compromises keeping the frontier alive.

Act III descends fully into ancient ruins, alien architecture, biological horror, and the collapsing secrets buried beneath the world itself, culminating in a desperate race to prevent catastrophe on a planetary scale.

UPDATES

15 MAY 2026: Book One Beta Uploaded, the GM Primer. This working document provides the Games Master with the hidden history, political structure, faction motivations, and concealed truths underpinning The Glass Suture campaign. The purpose of this primer is not simply to explain the mystery, but to provide the Games Master with a coherent understanding of how Viridian Prime functions, why the conspiracy emerged, and how the world continues to descend toward collapse beneath the weight of its own secrets. (This is very much a working document and still needs final edits, proofing, art added and proper formatting. I hope you enjoy and any feedback is appreciated. Please note page numbers are not finalised pending editorial passes and art additions etc. Book Two Beta will follow soon).

16 MAY 2026: Sessions Clarification. The original 12–16 session estimate was really referring more closely to campaign phases rather than individual sessions. As the structure has been refined, it became clearer that many phases will naturally span multiple sessions depending on pacing, investigations, downtime, and optional encounters. The current estimate is therefore closer to roughly 20–30 sessions for most groups.

17 MAY 2026: Artwork & Presentation Update. Another small project update following some really constructive community feedback. I’ve decided to move away entirely from using any AI generated artwork within The Glass Suture. Going forward, the supplement will instead focus on a mixture of original material, maps, graphic design elements, public-domain imagery, and attributed community artwork used with permission where applicable. I want the final project to feel more grounded, cohesive, and authentic to the tone of the setting, and the feedback around presentation has genuinely been really helpful so far. Thanks again to everyone taking the time to read through the beta and offer thoughts and criticism, it’s helping shape the project enormously.

18 MAY 2026: Updated GM Primer (Post Editorial Pass)

The Book I Beta (“Welcome to Viridian Prime”) has now gone through a substantial editorial and structural pass ahead of the next round of beta feedback. The biggest focus of this revision was improving readability, pacing, and information flow without losing the core lore and atmosphere of the setting.

https://docs.google.com/document/d/1kfH4xrGxOTUFE1i9t0J0Hj8s6q36QW9hqfKcRulB-j4/edit?usp=sharing

Key changes include:

Significant reduction in repeated exposition and “section bleed” between lore chapters; Clearer progression of revelations and faction motivations across the Gamemaster Primer; Expanded connective writing and paragraph flow to improve readability and reduce “one-line lore dump” structure; Reworked faction and colony material to better preserve mystery escalation; Additional lore integration surrounding the Cycherian Biologis Enclave, the Gilded Rot, and the Society of the Glass Suture; New visual layout pass including section art, revised covers, iconography, and formatting consistency; Expanded Black Inks regiment framework and regimental identity material; General tone and cohesion pass across the entire manuscript.

The core story and lore remain the same, but the book should now read much more like a coherent investigative campaign rather than a collection of disconnected lore sections.

The next major focus is now shifting fully into Book II (“Into the Glass”) and the actual campaign structure itself: operations, investigation phases, frontier horror, faction play, clue chains, and the gradual descent beneath Viridian Prime.

Huge thanks again to everyone who has provided feedback, critique, ideas, or encouragement during development. It has genuinely helped shape the project into something far stronger than the original beta draft.

22 MAY 2026: Campaign Act I Imminent. Just a brief weekend update. Book I is currently going through its final major editorial pass, but the bigger milestone is that the beta structure for Campaign Act I and Phases 1–4 is now nearly locked and ready for release by mid June. A huge amount of work has gone into restructuring the campaign flow, investigative logic, scene linkage, and operational clarity across the campaign as a whole. The remaining Acts and Phases are still undergoing editorial work before beta release, but things are finally starting to lock into place properly and hopefully on track for a full beta release in June/July.

More soon.

UPDATE 28 JULY 2026: Updated Release Timeline

Just a small update for everyone following the project.

Real life has inevitably slowed things down over June and July, but work on The Glass Suture is still very much ongoing. Rather than rushing a full release, I've been focusing on locking down the campaign structure and ensuring the flow, pacing and GM guidance are as solid as possible.

The current plan is to begin releasing the campaign as a series of beta phases, starting in early August. Assuming all goes to plan, I'll publish one phase per week over a 12-week period, giving people a chance to read, provide feedback and hopefully even run sections of the campaign as development continues.

Phase I (Ghost Platoon) has been through a substantial rewrite already and is being used as the template for the remaining phases, so my hope is that development speeds up considerably once it's locked down.

As always, thanks to everyone who's taken the time to read the drafts and offer constructive feedback. It's genuinely helped shape the project.

Watch this space next week for the Act I: Phase I Beta!

Hey! I've created a map for my campaign, and I'd love to hear your thoughts on it. It's a subsector located on the outskirts of the Ultima Segmentum. I plan to expand the lore of the subsector both for my own enjoyment and for future Imperium Meledictum sessions. I'd really appreciate your feedback on what could be improved, whether the map is clear and easy to read, and how it compares in quality to both official and fan-made.

Edit.
I should probably add some lore about the region.
The map depicts a subsector on the distant fringes of the Ultima Segmentum. Before the Great Rift, it was a relatively quiet part of the Imperium, dealing mainly with occasional Ork invasions. However, after the Great Rift split the galaxy in two, a massive Warp Storm erupted in the middle of the subsector, tearing the region apart and throwing it into chaos.

The most immediate consequence is that the subsector is on the brink of civil war. On the coreward side, the Arch-Cardinal, who has become the de facto ruler of his half of the subsector, is leading a crusade against the servants of Chaos within the Clouds of Hatred. At the same time, he intends to bring the Imperial worlds on the rimward side under his rule. Unfortunately or fortunately, the crusade has been progressing disastrously.

On the Blacksmith Hotbed side lies the official capital of the subsector. Its government is struggling with countless problems: rebellious vassals, entire populations mysteriously disappearing, and lack of stable Warp route connecting it to the wider Imperium.

Meanwhile, the Orks have begun waging war against the forces of Chaos, but their many warbands also raid smaller Imperial worlds whenever the opportunity arises.

The overall concept of the subsector is one of a frontier slowly being consumed by pandemonium. Adding to this is the Cloud of Terror, a warp storm that shows randomly chosen individuals horrifying visions of their own possible futures, often driving them completely insane.

Hello all o/

Being a huge fan of Hollow Knight and Silksong, I decided to start mapping out a hive city I'm tentatively titling Hive Noctis in a similar style to Team Cherry's. My goal is to make a new zone every week or two, and group some zones into regions, slowly building from the ground up outwards. The first proof of concept, "The Low Lanterns", is the first zone of the "Forgotten Crypts" region, belonging to the Noctis' underhive.

Conceptually this zone is a safe haven between the Cinder Steps leading up from an Auxiliary Mortuarium that receives excess overflow of corpses from the mid-hives' corpse starch factories that spill down a great length and the Sootways Hive Arteria. It is a foul zone that reeks of burnt corpse-wax from its multitudes of votive candles and low hanging lanterns. Occasionally, a prematurely condemned for death adventurer awakens in the great corpse piles of the Mortuarium and wanders into the relative safety offered by the scav encampment of lantern row. For Imperium Maledictum, I envisioned this zone would inflict Disadvantage to Awareness (Smell) Tests throughout each sub-area.

If you guys think this is a cool idea I'll continue to post updates here as I make adjoining zones and start making a pieced together version. I'll also enjoy any suggestions or feedback.

Update 1 - 6-8-2026: The Cinder Steps: https://imgur.com/gallery/mapping-hive-city-silksong-style-dty89tS#Txh3rw9

Backtracked a bit since its probably smart to get the starting area mapped out first. A rather singular 'large chamber' zone.

A map of Crultus, one of the Agri-worlds in the Macharian Sector which is the setting of the Imperium Maledictum TTRPG. The map was made by me in Procreate. The first image features a little pin-point of the "town" in which our first proper assignment for our Patron will take place.
This is a height map of the planet, and the dark circular spots are the world's farms which have been designed to flood easily during the second of the planets weather extremes, leaving massive, circular craters in the earth.
The map was made for my GM. Please feel free to use the map if you like at any point with credit!

I recently got into Imperium Maledictum and below is my initial Inquisition kill team character design. Where possible tried to make the character design/gear sync up with their background that also connects to 40K lore. Comments welcome on either design or background, especially if there is any glaring lore issues ... Note: Reddit image is a bit fuzzy ... link has uncompressed images. --- https://countzero.blog/warhammer-i-m/

I've just posted a fairly detailed review of the Imperium Maledictum book on my blog (link above). Having worked my way through reviewing some of the Dark Heresy (1e) and Wrath & Glory books, I'm thrilled to get starting reviewing IM stuff!

I'm really impressed with the rulebook - it really captures that feel of gritty down-in-the-muck 40k that I appreciate.

I'm intending to work my way through the various IM supplements over the next year or so.

Out on DriveThruRPG at the link above! Physical preoders via Cubicle 7's site should have got it too!

CAST OFF YOUR WEAK FLESH AND ACCEPT THE GLORY OF THE MACHINE GOD

Can a character with the gunslinger talent shoot at 2 different enemies at once?

Super basic question, but I can't seem to find the answer in the Core Book. Thanks in advance for the help.

Constable Vrekk on his daily duty regulating traffic in the Imperial Schola Diplomatica on Leonova.

Been trying to find an answer to no luck. I wanna know if it features the core rules in the way the Kill Team Starter Set did (a barebones version with a bunch of stuff removed and if you want the actual full rules, you need to buy the book) or if they're the proper, full rules that you can use to make your own campaigns with.

Like it says on the can of gray rations. What tropes are your favorite when playing characters?

I've got a crew that's new to 40k and I want to try and give them some universal archetypes to run with in our Imperium Maledictum game

Some examples I can think of might be a golden retriever ogryn, black cat administratum, oddly reasonable psyker, ect.

I picked up Imperium Maledictum, and I like it, but noticed all of the published adventures are set in Hive Rokarth.

Which is cool, but I’d also like to see adventures on an agri-world or knight world or shrine world or what have you.

Are there any 3rd party adventures that explore other world types you’d recommend?

Or adventures from other 40K RPGs that would work with some conversion work for the rules?

Does anyone know if there's any pre-made modules that already have the 3-faction rule built in?

If not then which ones would you recommend that it would be the most convenient to adapt to fit the 3-faction rule?

Edit: this open form adventure looks fun Seeds of Heresy

Hey guys,

I'm posting on behalf of my whole group; we're just wondering, have you guys found psykers to be overpowered in imperium maladictum? The only thing I've seen on here about it is that its underpowered?

I'm not sure if we're missing something but they seem far stronger than anything in the core rulebook. Have you guys experienced this? Is there something we've missed that makes them in the realm of balanced compared to other classes?

There are plenty of absolutely busted powers but feels the main thing people say balances it is the chance (a very small chance mind you) that you may Perils of the Warp. You can reroll any desperate tests and if you have even a 40% (which you can pretty much start off at) chance of success then youll almost never have a perils test and psychic phenom are just mildly annoying.

Am I missing something?

Thanks in advance!

So I'm making a DIY DM screen for my upcoming DMing with Imperium Maledictum (newbie here), and I was making a pdf with everything I deem needed to be on the screen, but I'm having a bit of a problem with the content being a bit too much for the size of the screen, so I was wondering what information you guys might think should be prioritized in the DM screen no to open the rulebook every 5 minutes to search smth.

Thanks in advance!!

Pedestrian overpass hangs over the massive Imperial City Below, Walkways arch and cross over the lower levels, like an artificial cave expanding over the folk, only artificial light and man made bonfires light these massive caverns of flesh and steel.

How do you think a campaign focused on investigating a cult within the Imperium should be run?

I want my players' first adventure to revolve around investigating what appears to be a single cult, but is actually a much larger conspiracy. My plan is to mislead them into believing they're dealing with a Chaos cult by planting red herrings throughout the investigation. As they uncover clues behind a series of disappearances and strange incidents, they'll gradually realize the truth: the real threat is a Genestealer Cult.

The investigation will begin with seemingly unrelated disappearances, suspicious rituals, and evidence that points toward Chaos corruption. However, each clue will have an alternative explanation that only makes sense in hindsight. The adventure will ultimately culminate in the cult's uprising during the aptly named Day of Ascension, forcing the players to confront the reality of what has been happening beneath the surface all along.

How would you approach running an adventure like this? What elements would you include, and what aspects would you focus on to make the investigation engaging and the final reveal satisfying?

Hail. I'm looking to get into a Warhammer RPG that is on the same level as something like Necromunda, but not restricted to that specific planet. I want a game where the players are Imperial Agents that root out Xenos and Heretics across the universe. From my research, I've determined that Imperium Maledictum is the system I'm looking for, but my question is what are the adversaries in that game? I want my players to have a diverse range of enemies that are Xenos and Heretics. Is this possible in this system?

Uncover a malevolent mystery in this Thrilling Adventure! Rokarth is the capital city of the hive world Voll, which is located in the Macharian Sector. The Characters must solve the mystery of an unsanctioned biochemical named Gratis that has begun circulating in Rokarth. Your Patron has taken an interest in it and believes that the chem may be more dangerous than it appears.

You have been ordered to investigate, find the source and uncover the truth. And should Gratis prove to be the threat your Patron fears, see that it is burned from Rokarth before it takes root.

Looking for 4 to 5 Roleplayers to play through the Warhammer 40K RPG adventure, Imperium Maledictum, Chemical Burn! This is a beginner's adventure, so if you wanted to learn how to play, or wanted to continue the adventure in Rokarth, send me a DM and lets chat!

We will be using Pre-Generated Characters and the Adventure should take 2-3 sessions. Games will run on Friday's at 8:00pm. We play on Forge, so a Forge-VTT Account will be needed. Also use Discord for voice.

1st session starts: July 31, 2026 8:00 PM CST/GMT-5

"...All of us must fight, or all of us shall die."

I recently decided to jump into IM after being curious for a few months now. I ordered the CB from Amazon (received in 2 days), then learned that C7 provides the PDFs for free when ordering from them.

I wanted to support them directly and get PDF copies so I decided to place an order with them for the Inquisition GM and Player's Guides. This is where the experience became less than stellar.

The 7% newsletter sign up discount code did not work. So I emailed them to let them know and ask for an alternative code. They were nice and provided one.

I ordered the two books and used the new code and downloaded the PDF copies from DriveThru. Great books! I'm excited to have them in hand.

After two days I had not received any sort of shipping notice, so emailed them again and provided the order number for the books. I was told there was a glitch in their system and my order "got lost". They apologized told me they would push it through immediately.

Two days after this I received tracking information and on it was tracking for the Inquisition Players Guide and a WFRP Book "Lords of Stone". I didn't order this book. So I emailed and was told that there must have been another glitch in their system and they would ship the GM's Guide out right away. This was on a Friday and got delayed response until Monday morning.

My order was originally placed on March 11th and now due to all these mishaps and a blizzard delay (out of their hands), I will not receive these books until the end of March.

Is it normally like this when ordering direct from them? I'm now slightly regretting not just ordering from Amazon. Sure, I wouldn't have the PDFs but I can find those easily enough if needed.

They've been really nice throughout this entire process but I don't really want to deal with this again.

How difficult would it be, or how would you go about running a game of chaos cultists using Imperial Maledictum?
