OSE Foundry Bounty: 5 New Modules!

Hot from the forge! Five new Old-School Essentials modules have just landed on Foundry VTT, supporting your virtual OSE campaigns with first-party dungeons, zines, and short adventures. Whether you’re running a long campaign or need a quick one-shot, OSE’s finest offerings are just a click away.

Here’s what’s new:

• Adventure Anthology II – Reptiles, rakshasa, reaving skeletons, and more await in our second short adventure collection.
• Carcass Crawler #5 – The latest issue of our official OSE zine, packed with new classes, poisons, equipment, magic, monsters, and a level 0 funnel adventure.
• Quick Delve #1: Milk – Undercover a surreal secret surrounding a subterranean lake of milk, with sweet rewards for smart adventurers.
• Quick Delve #2: The Grotesques’ Grotto – Our latest Quick Delve, offering a delirium-haunted temple crawl rich in peril and treasure.

All modules are fully implemented for smooth online play, with maps, encounters, and content ready to run. If you’ve been building your OSE library on Foundry, now’s the perfect time to expand your digital dungeon.

OSE Month Collaborator Highlight: Agamemnon Press & The Other Side

OSE Month 2026 is coming in May, with many of the old-school RPG community’s star names joining us in this crowdfunding bonanza to create demon-themed adventures and supplements along with our own Demonic Grimoire.

Haven’t heard of some of our fantastic collaborators? Allow us to introduce you to:

Agamemnon Press

If you’ve wandered the psychedelic nightmare realms of The Painted Wastelands or followed the grotesque adventures of Mr Unpronounceable, you already know Agamemnon Press delights in occult-inspired weird fantasy with sci-fi elements. If you don’t, then do check out The Painted Wastelands Bundle of Holding for a great deal on this surreal setting.

For OSE Month, expect a little more metal in your psychedelia with the upcoming HELLCRAWL, which asks the question: “Where do murderhobos go when they die?” Naturally, they descend to the burning hell itself, where the battle and plunder only get bigger and badder! We’re looking forward to seeing intrigue, bizarre loot, and absolutely sick art from author Christopher Willett and artist Tim Molloy.

The Other Side

Timothy S. Brannan’s The Other Side blog has been a fixture of the OSR scene since the early days, offering years of nuggets of knowledge and game ideas regarding old-school play. The mastermind behind a slew of RPG products that deal with witches, horror, and occult magic, Brannan is a natural fit for our demonic OSE Month.

From the warlock’s pen comes the Codex Qliphothica, a work that brings the Other Side to life as an abyssal realm populated by fiendish foes more terrible and strange than the demons themselves! We can’t wait to learn more about the Qliphoth and their dread domain.
