Find events near youBrotherwise's Cosmere RPG is the most-funded tabletop game in Kickstarter history, pulling in $14.7 million in 2024 on the back of Brandon Sanderson's enormous fanbase. The Stormlight Archive setting launched digitally in 2024 and in hardcover last year, and Mistborn was always part of the long-term plan. The new book covers the original Final Empire trilogy, with players burning metals as Allomancers, sliding on coin-shod feet across rooftops, and trying very hard not to die in the ash.
There is more incoming alongside it. The Mistborn deckbuilding game will get a Well of Ascension expansion in November 2026, adding over 100 cards, four new playable characters including Vin and Kar the Inquisitor, and a co-op Siege of Luthadel mode. A Stormlight solo mode is also in the works, with future Cosmere sourcebooks promised for Elantris, Warbreaker and the Worldhoppers.
