OSE Month Free Adventure and Soundtrack Unlocked! AMA and Livestreams Incoming!

OSE Month Update - Free Adventure, AMAs, and More!

The fiendish fundraising frenzy that is OSE Month has raised a glittering hoard to rival Mammon himself! The Old-School Essentials Demonic Grimoire alone has raised over $361,000 at the time of writing, and OSE Month as a whole, including our 16 collaborator projects, stands at over $551,000.

Your support has been absolutely amazing, enabling us to offer even more demonic blessings to reward devotees and tempt the curious.

Not only has the Demonic Grimoire itself been upgraded with ribbon bookmarks and printed black page edges (a first printing exclusive), but we’ll also be throwing in a holographic sticker and a FREE copy of Quick Delve #5: Golden Lies to all our backers.

And that’s not all! We now have the funds to commission an original OSE Month soundtrack, with each track themed around a particular infernal hell realm. 6 out of 8 potential tracks are unlocked so far, with the digital album going out to all backers (of any OSE Month project).

We’ve also added pre-orders for the 2026 updates of the OSE Referee’s Book and Player’s Book as part of the pledge manager for the Demonic Grimoire. These new core books come with more illustrations, play examples, and optional AD&D-inspired rules. Want to know more? See our FAQ.

The crowdfunding campaign runs until 11:59 PM, June 5, so there’s still time to back and get the OSE Month-exclusive version of the Demonic Grimoire, all the freebies, and some awesome zines, adventures, monster books, and more from our collaborators!

As an extra diabolical temptation, here’s a snippet from the Demonic Grimoire detailing Carcerus, The Iron Labyrinth, an oppressive hell realm under the control of the demon lord Bethgor, Father of Chains:
