Keepers by Other Authors

Adventures written by other designers, rebuilt as Adventure Keepers — one file you open in a browser, where the tables roll when you click them, the monsters drop into a combat tracker, and the maps and handouts are already inside. Every one of these is sold or given away on the author's own page. Follow the link, and you're on their storefront.

Their adventure. Their words. Their shop.

I didn't write these. I don't sell them, I don't host them, and I don't take a cut. A designer said yes, sent me their adventure, and I built it into a Keeper and handed the file back — not one word of their text changed, their own art, their own layout. What they do with it after that is entirely theirs.

The one thing every Keeper carries is a small line at the end saying it also runs in Gnasher's Grimoire, my free DM app. That's the whole arrangement. The file works perfectly well on its own; drop it into the Grimoire and it does considerably more.

Battle for Carrion Vale

by Joseph R. Lewis

Old-School Essentials Dark sandbox Name your own price

The forces of Law and Chaos clashed at Castle Yennagor, and by nightfall an explosion had levelled the castle and both armies. Now the survivors stir. Your party are battlefield scavengers who pick their own side and their own goal — escape the field alive, plunder the dead, or reach the castle and find out what happened inside.

Get it on itch.io Downloads from Joseph R. Lewis's own itch page. Twenty illustrations, clickable d66 tables, and every fight ready for the tracker.

More are on the bench. If you're a designer and you'd like one of yours here, the offer is below — and if you've already got a Keeper edition of your adventure listed, send me the link and I'll shelve it.

Designers: want a Keeper edition of your adventure?

I'll build one, free, and hand it to you. No catch and no invoice — I'd just like more adventures in the world to run like this.

Your words exactly as written. It's typesetting, not editing. I don't rewrite a line, and nothing is added to your text.
You own it and you list it. Sell it, bundle it, give it away. I take no cut and host no file. The rights never leave you.
You see it before anyone else does. Nothing goes anywhere until you've opened it and said it's right.
One line is the whole fee — a small note at the end saying it also runs in Gnasher's Grimoire, with the link.
One email, ever. If you're not interested, you'll never hear from me again.

Send me the adventure as Markdown, a PDF or a Word file, plus any cover art you're happy to see on it. If it's your own IP (or SRD / CC‑BY), it's a candidate.
