Step into a universe of adventure and Investiture! The Cosmere Roleplaying Game is an original system designed for heroic, character-driven stories. Based on the best-selling novels by Brandon Sanderson, this wave of the living RPG invites players to explore the world Mistborn.

The story of Mistborn begins in the Final Empire, a society on the brink of collapse. Humanity toils in service to the Lord Ruler, his favored nobles, and the fanatical Steel Ministry. As the world of Scadrial faces a final cataclysm, the servants of Ruin and Preservation will decide its people’s fate.

Centuries after the fall of the Final Empire, an age of peace comes to an end. The second era of Scadrial brings new frontiers and new wonders, from railways and automobiles to airships and skyscrapers. But upheaval looms as the servants of a new god vie for control of the world.
