THE GENESIS
The Incident on Saint Isadore Caenum campaign (gonna love typing that out a thousand times) came to mind of the Game Master in 2023 as most things do. Late at night..can’t sleep. It looked like this:
For whatever reasons (and there were probably many)it sat unused. No games of Warhammer 40k were played and no more work was done. Fast forward to September 2025. It was announced that the campaign would finally be launched. Players chose armies and the narrative at the top was written and sent out. The flowchart above remained the basis of the campaign structure.
Then nothing happened. Three false starts later and boom! Game on.
THE CONCEPT
…has evolved. The campaign plan was to combine Warhammer 40k with Battlefleet Gothic. Games of one would flow into games of the other. This remains the case. BFG has not been played for years. Fleets were scattered and incomplete. The game had previously been supplanted by X-Wing and sat collecting dust. Not wanting to cross pollinate franchises, X-Wing is out and BFG is in.
When the campaign was to start in September 2025, it was pretty straight forward, but the delays brought evolution. A 3D FDM printer was gifted to the GM by the group and another member now owned a resin printer. This time plus new toys brought campaign expansion.
THE NEW STUFF
The GM decided that it was no longer fun to just paint boring ol Standard 40k miniatures so developed a plan. Before each scenario, the GM would paint up random, tangentially related minis and add them to the campaign. Whatever was painted in time was thrown in. Choice of scenery also greatly influenced the scenarios. This has resulted in new characters, units, and vehicles. As an example, you will soon meet Mr HaeruthThe Seer, an early protagonist.
THE OLD STUFF (aside from the players)
The Irregular(s) gaming group doesn’t play a necessarily traditional 40k game. We currently use 9th edition rules with the caveat that if you play a model that is armed differently than allowed by the rules (usually because it was legal in some past edition when you assembled the thing) then that is what your little dude(ette) is carrying.
Our army lists are also non-traditional. Our deathguard army has access to a maulerfiend/forgefiend played by none other than Nigel from our Necromunda campaign.

| Hello |
That’s not all. One of the players is slowly inserting a rogue trader squat army into the game one unit at a time by adding them to an Imperial Guard army. If you paint a mini, we will make stats for it.
A NOTE ON MODELS AND CONTINUITY
We at Irregular(s) like to field as many painted miniatures as possible. It makes us feel all warm and tingly inside. We usually do a pretty good job. This campaign is gonna make us cold and numb. There will be unpainted mins/units/armies and there will be half conceived scenery on the table. Bear with us, we are currently under construction.
In the narrative/plot there will be inconsistencies, changes in spelling and bad grammar. We are not a serious operation.
THE PLANET
With that we bring you The Incident on Saint Isadore Caenum.
