OSE Month 2026 is over and — thanks to your support — it has been an overwhelming success!
What Next?
Now that the campaign is over, our next stage of work begins: getting the Demonic Grimoire and other products off to the printers! We've already prepared the final print files, which should be going into technical approval with the printers soon. We'll keep you updated as things progress.
PDFs and Surveys
We plan to send out pledge manager surveys to you all around mid/late July. This is the survey asking for your shipping address, paying for shipping fees, purchasing add-ons, and confirmation of other details like T-shirt size (for those who ordered shirts).
Filling out this survey will also have a fabulous benefit: you'll get access to all the finished PDFs included in your pledge level! We hope you'll all enjoy seeing the Demonic Grimoire and other products in their full, hellish glory and planning how to integrate the new monsters and material into your campaigns.
The pre-order store will also be open when surveys go out in case you have friends that missed the campaign and want to pick up a copy!
Thank You For Your Support!
We have tons of exciting plans for further OSE supplements and adventures, and the resounding success of the Demonic Grimoire and OSE Month means the world to us!
The Necrotic Gnome team is already working on a sequel / companion to the Demonic Grimoire entitled the Necrotic Tome. This OSE supplement delves further into realms of dark fantasy, with a focus on undead and necromancy. It details the Land of the Dead, 4 new deities (including everyone's favourite bad guy, Orcus!), a horde of new sinister monsters, a full necromancer class, and lots more necromantic goodness.
Less than 12 hours left for Demonic Grimoire and OSE Month!

Final OSE Month Achievement UNLOCKED!
We've passed $625k (whoa!) in the month and unlocked the final collaborative achievement:Two MORE tracks added to OSE Month Hellscape Digital Soundtrack! This means that the digital Hellscape soundtrack will have two additional tracks corresponding to the final two hell realms in the Demonic Grimoire. That makes a total of eight songs, one for each realm of hell! We'll be experiencing (in sonic form) the ice hell of Zonth, the iron labyrinth of Carcerus, the endless war of Xarxus, the savage lands of Gargathuul, the burning hell of Nethria, the noxious realm of Oblivex, the infested swamp of Malfflesia, and finally the cobwebbed abyss of Ulobor. Every backer in all OSE Month projects will receive this digital soundtrack.
Last Chance for a Free OSE Month Booster Deck!
This is your last chance to get the booster pack for FREE by backing the Demonic Grimoire + any 6 projects in OSE Month. This pack is exclusive to OSE Month and will not be reproduced.

We have tons of exciting plans for further OSE supplements and adventures, and the resounding success of the Demonic Grimoire and OSE Month means the world to us! We'll keep you updated in the coming months as the Demonic Grimoire goes to print and squirms its diabolical way towards shipping out to you all.
Infernal regards, the Exalted Funeral + Necrotic Gnome teams
It's hard to believe that we're in the final few days of OSE Month! We have a few updates for you as the blood-moon sets on this benighted month...
Full Hellish Soundtrack Almost Unlocked!
We're tantalisingly close to unlocking the final OSE Month achievement at $625,000 total funding across all 17 projects: the final 2 tracks of the hell-realm soundtrack. Once we reach that final goal, the soundtrack will be complete at 8 tracks — one inspired by each hell realm in the Demonic Grimoire.
All backers of any OSE Month project will receive a digital download of the soundtrack once it's complete.
This would be a great moment to have another look at the complete OSE Month project lineup to see if anything tickles your fancy. There's a hefty selection of diabolical adventures, settings, supplements, art books, minis, and more, many of which will ship with the Demonic Grimoire at a heavily discounted shipping rate. So don't miss out!
Print File Preparation Under Way
As noted in the campaign description, the Demonic Grimoire and other items are 100% complete. Now that we have a clear picture of the number of copies of each item we'll need to print, we're already preparing final print files to send off to the manufacturers.
Normally this is the kind of update we'd be sending in the months after a crowdfunding campaign has ended. But in this case, we're ahead of the game. We'll keep you updated along the way as the Demonic Grimoire and your other rewards enter manufacturing.

Golden Lies Actual Play Part 2
Part 2 of our Golden Lies video play-through is up on YouTube now. Remember that all backers will be getting a copy of Golden Lies, so this is a great chance to get an advance preview of the adventure.
Part 2 sees the group continue through the demonic adventure! A false goddess rises, her cult swelling with gold and devotees. In a half-sunken temple in a fly-infested swamp, miracles mask a darker truth. Followers vanish and wealth flows. Can players uncover the deceit before the Radiant Queen’s lies consume all?

We bring diabolical tidings today that will be sure to fill you with wicked glee...
Golden Lies Free to All Backers!
We have just crossed $350,000 funding for the Demonic Grimoire, which means we've unlocked our final achievement — all backers at physical pledge levels will be receiving a free print + PDF copy of the Golden Lies adventure! (Backers at the digital-only Acolyte level will receive the adventure in PDF.) Here's a refresher on what awaits you in this adventure...
A false goddess rises, her cult swelling with gold and devotees. In a half-sunken temple in a fly-infested swamp, miracles mask a darker truth. Followers vanish and wealth flows. Can players uncover the deceit before the Radiant Queen’s lies consume all?
A demon-themed short adventure designed for 1–2 sessions of play, perfect for side quests, one-shots, and conventions.
Suitable for around six characters of 4th–6th level.
We don't plan to announce further achievements for this project, so as not to expand the scope and timeline. However, there are still achievements on OSE Month as a whole...
Soundtrack Expanded to 6 Tracks!
The total funding across all 17 OSE Month projects has also hit a new milestone! We've surpassed $525,000, which means that the hellscape soundtrack will be expanded to a total of 6 tracks. All backers will receive the soundtrack in digital form once it's complete.
Looking at the results from the poll voting on which hell realms to include first in the soundtrack, we've unlocked the following tracks so far:
Nethria (realm of Infernus, Lord of Hellfire)
Oblivex (realm of Ooyxblix, the Faceless One)
Ulobor (realm of Sillith, the Spider Queen)
Zonth (realm of Avaraz, the Ice Queen)
Carcerus (realm of Bethgor, Father of Chains)
Malfflesia and Xarxus are tied! A d6 tie-breaker speaks for the carnage of Xarxus (realm of Drazoggoth, Prince of Slaughter)
So that means we just have Gargathuul (realm of Ghursag, Lord of Beasts) and Malfflesia (realm of Phranax, the Plaguemother) to unlock at $625,000 total across all OSE Month projects!
