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 lone watchtower at the forest's edge, a light still burning in its window, and the ravens that never leave. The next dark-fantasy chapter of the Edenfall Collection - coming soon to DriveThruRPG.
Looking for a custom supplement built for your campaign or publication? Commission me directly.
Whether you're a solo creator or a publishing house, I bring professional TTRPG writing craft to your project - one commission at a time.
Tell me about your project and I'll get back to you within 2 business days.
The same craft behind my published worlds - deep research, clean structure, and a voice that holds a reader - applied to the work that moves a business forward. Clear, reliable, deadline-driven writing for brands, founders, and publications. No dice required.
Researched, search-aware articles and posts that rank well and read even better. Voice-matched to your brand and structured for skim-readers and search engines alike - delivered ready to publish.
Thought-leadership articles, bylined features, and long-form pieces written in your voice and published under your name. I handle the drafting and shaping - the ideas, and the credit, stay yours.
Line edits, copy edits, and final proofs that sharpen clarity, tighten structure, and catch every last error. You get honest notes on what's working and what isn't - not just red ink on grammar.
Not a fantasy project? The process is exactly the same - send a brief and I'll reply within two business days.
