Keystone Fantasy Roleplaying

This is currently my primary project: a fantasy roleplaying game primed for the superlative Cortex Roleplaying Game. Its flagship is Ascent to Prime, a tutorial campaign set in the epic megadungeon of Tour Toriel. Both players and GM can learn Cortex by playing Cortex.

The Keystone Corebook will follow, along with a number of Toolboxes presenting fun ways to apply the Cortex rules to different corners of a sprawling fantasy RPG.

Keystone is distributed through itch.io, and the first adventure is free!

  • The Court of the Tyrant at Tour Toriel Released!
    The Court of the Tyrant at Tour Toriel is finally released, out in the wild, and most importantly off my desk! This is the fourth installment of the Ascent to Prime campaign I’ve been developing which teaches new players how to play (and run) Cortex Prime games. It’s really cool, if I do say so…
