Brandon Sanderson’s Stormlight: Tidebreakers Tabletop Game Coming

If you have seen headlines doing the rounds about a major new Stormlight Archive sequel arriving in late 2027, you might want to pause before clearing space on your fiction shelf. While there is indeed a brand-new official entry in Brandon Sanderson’s epic fantasy universe scheduled for autumn 2027, it isn’t a prose novel. Instead, Roshar is getting a major expansion on the tabletop gaming front with Stormlight: Tidebreakers.

Published by Brotherwise Games, Tidebreakers is an official campaign adventure for the Cosmere TTRPG. Designed as a level 10 to 16 campaign module, the release will send player groups into the perilous high seas of the Reshi Isles. For those following the broader tabletop rollout following Sanderson’s massively successful Cosmere crowdfunding campaign, this announcement fills out a crucial higher-level bracket for the system.

Where Tidebreakers Fits in the Stormlight Canon

For lore enthusiasts trying to place this on the timeline, Tidebreakers takes place alongside the events of the core books, specifically spanning the timeline of Oathbringer, Rhythm of War, and Wind and Truth. If you ask me, setting a campaign in the Reshi Isles during this specific era is a clever move. It lets players experience the chaotic background of the global conflict without tripping over the core cast’s primary storylines in Alethkar or Urithiru.

Narratively, the module serves as a direct follow-up to Stonewalkers, the level 1 to 8 adventure module already released for the system. Eagle-eyed players will immediately spot a numerical gap there, as Stonewalkers wraps up at level 8 while Tidebreakers picks up at level 10. According to details shared by the design team, gaming groups have a couple of ways to bridge those two missing levels.

Dungeon Masters can either run custom homebrew adventures set across Roshar, or players can leap straight into level 10 if they want to jump into the action. Another official option coming down the track for original campaign backers is the upcoming Showdown in Shadesmar adventure module, which offers a journey through the Cognitive Realm to bridge the gap.

Tabletop Expansion Over Prose

It is easy to see why casual observers might mistake game announcements for main-line novel news given the sheer volume of output Sanderson produces, but his publishing schedule for fiction remains distinct. The author’s own projected timelines point toward other projects in the coming years, meaning readers waiting for the next main sequence prose instalment will be waiting a while longer.

However, for tabletop players, Tidebreakers promises substantial depth. Built on a D20 system tailored specifically to capture the mechanics of Surgebinding, Lashings, and Shardblade combat, the module provides a structured sandbox. While the book presents a guided narrative through the Reshi Isles, Brotherwise Games has emphasised that players are free to venture off the beaten path, interact with original non-player characters, and forge their own path through Roshar’s storm-wracked seas.

Retail distribution for Stormlight: Tidebreakers is expected around October 2027, though exact shipping dates for international stock will likely be refined closer to launch. Whether you plan to roll dice as a Windrunner or simply enjoy watching the Cosmere expand across new mediums, it marks another ambitious step in bringing Sanderson’s world to life.
