Ashforge Studio is a solo TTRPG content studio. I write adventures, lore, stat blocks, and supplements for publishers, creators, and Dungeon Masters who demand more from their worlds.
My 5e supplements are available exclusively through DriveThruRPG and Patreon. Every title is table-tested, lore-first, and designed to drop into any campaign.
A dark fantasy adventure for the 5th Edition - deep woods, hidden horrors, and a road that doesn't end where it should. Designed for drop-in play or as the opening chapter of a longer arc.

Fill out the commission form with your project brief. I'll respond within 2 business days to confirm scope, timeline, and fit.

I write. You'll receive a full first draft by the agreed date - structured, playtested where applicable, and ready for your feedback.
Up to two rounds of revisions are included. I work with your notes to sharpen tone, balance mechanics, and nail the details.
Final files delivered in your preferred format (Google Doc, Word, Markdown, or InDesign-ready). Balance of payment due on delivery.
