Who Are We?

ArcaneOso RPG was founded in 2025 by a team of besties and career creative professionals (well, one is a scientist) who also happen to be obsessed with tabletop roleplaying games like Dungeons & Dragons.

Today, we strive to create rich, narrative-driven, 5.5e compatible worlds, characters, and stories that are fun, balanced, and satisfying for adventurers and DMs alike.

We strive for accessibility through clean, thoughtful, user-first book design so players at any level can build and run games in our breath-taking worlds with total confidence.

As creatives ourselves, we proudly support real artists creating real content. We pledge to always be AI-Free and to provide you with beautiful, high-end content generated by real, human creators.

In May of 2026, we launched our first crowdfunding campaign for Nightmares in Neverland, a new 5.5e horror setting based on J.M. Barrie’s Peter Pan and other legendary fairytales & poems.
