Executive Overview
The landscape of modern tabletop roleplaying games (TTRPGs) has undergone a seismic shift, driven largely by cross-media adaptations of high-profile literary universes. At the forefront of this movement is author Brandon Sanderson and his vast, interconnected literary cosmos known as the Cosmere. Since 2020, Sanderson and Brotherwise Games have worked tirelessly to translate the intricate magic systems, sprawling geography, and epic stakes of Sanderson’s novels into tangible tabletop experiences. Following the historic, record-breaking crowdfunding campaign that launched the core Cosmere RPG rulebooks last year, the partnership is preparing its next major milestone: the highly anticipated Mistborn expansion.
Slated for an official release on November 4, 2026, and currently available for preorder via major retailers like Amazon, this new wave of sourcebooks invites players back to the ash-choked empire and industrializing landscapes of Scadriel. The upcoming release comprises three distinct volumes: the Mistborn Handbook, the Mistborn Campaign Guide, and the introductory Welcome to Scadriel guide.
Together, these manuals provide a comprehensive toolkit for Game Masters (GMs) and players alike, offering deep mechanical integration for the planet’s iconic Metallic Arts—Allomancy and Feruchemy—while spanning two distinct chronological eras. This expansion represents more than just a routine supplement; it is the realization of a decade-long evolution in how fantasy literature is adapted for interactive play, building upon earlier attempts by Crafty Games and complementing Brotherwise’s own critically acclaimed board game adaptations.
Detailed Chronology: From Page to Tabletop
To fully understand the weight of the 2026 Mistborn TTRPG expansion, it is necessary to trace the trajectory of Sanderson’s tabletop adaptations over the past decade and a half. The journey of bringing Scadriel to the gaming table has been marked by experimentation, iterative design, and an ever-deepening relationship between author and audience.
2012: The Crafty Games Era and the Mistborn Adventure Game
Long before Brotherwise Games began conceptualizing a unified Cosmere RPG, Brandon Sanderson’s universe made its first foray into the tabletop space through Crafty Games. In 2012, the studio published the Mistborn Adventure Game, utilizing the proprietary Investment-driven Storypath-adjacent mechanics of its time to immerse players in Era 1 Scadriel.
While the game enjoyed a dedicated cult following and received several supplemental sourcebooks that fleshed out the Final Empire, it operated in a vacuum. At the time, the Cosmere as a unified publishing phenomenon was far less structured than it is today, and the ruleset struggled to capture the cosmic scale of Sanderson’s broader vision. Over the years, as Sanderson’s bibliography expanded—introducing worlds like Roshar (The Stormlight Archive) and Nalthis (Warbreaker)—the 2012 adventure game faded into the background, eventually becoming a relic of an earlier era of indie RPG design.
2020–2025: The Brotherwise Partnership and the Unified Cosmere RPG
Recognizing the need for a cohesive, rules-light yet mechanically robust system that could span every corner of the Cosmere, Sanderson partnered with Brotherwise Games in 2020. This collaboration yielded immediate dividends, branching into both board games and roleplaying systems.
Among these early successes was Mistborn: The Deckbuilding Game, which received widespread praise for its tight mechanics and thematic integration. Reviewers lauded it as a refreshing entry in a crowded genre, earning high marks for how well it mirrored the resource management and tactical planning characteristic of the books’ heist-like plots.
Concurrently, the design teams laid the groundwork for the Cosmere RPG, culminating in a blockbuster crowdfunding campaign last year that shattered expectations and secured millions in backer funding. The launch of the core rulebooks established a baseline framework for running adventures across the Cosmere, laying the technical foundation for world-specific expansions.
2026: The Mistborn Expansion Launch
Now, in 2026, the partnership enters its most ambitious phase yet. The impending November 4 release of the Mistborn Handbook, Campaign Guide, and Welcome to Scadriel guide bridges the gap between the generalized rules of the core system and the hyper-specific lore of Scadriel. By structuring the books to accommodate both the high-fantasy, dystopian oppression of Era 1 and the steampunk/noir detective aesthetic of Era 2, Brotherwise Games has created a modular ecosystem that caters to diverse playstyles.
Supporting Context & Metrics: Breaking Down the New Supplements
The 2026 Mistborn expansion is not a monolithic tome; rather, it is strategically divided into targeted products designed to lower the barrier to entry while offering maximum depth for veteran players.
1. The Mistborn Handbook
Serving as the mechanical engine for any Scadriel-based campaign, the Mistborn Handbook is the definitive sourcebook for character creation across both eras. Unlike the Stormlight Archive-focused materials found in earlier releases, this handbook pivots sharply toward the Metallic Arts. Players gain access to comprehensive rules for Allomancy (burning metals for superhuman physical and mental enhancements) and Feruchemy (storing attributes like strength, speed, or mental acuity in metal minds for later use). For GMs, the handbook offers tailored guidance on balancing encounters involving metal-reliant characters, ensuring that combat remains dynamic and true to the source material.
2. The Mistborn Campaign Guide
While the handbook provides the tools to build a character, the Campaign Guide provides the world to test them in. This volume is engineered to drop player characters directly into authentic, lived-in settings drawn from the novels. Crucially, the guide introduces multi-era campaign structures with narrative consequences that "echo across the centuries."
- Era 1 Campaigns: Designed specifically for character levels 3 through 6, these adventures unfold against the backdrop of the Lord Ruler’s final centuries, where ash falls from the sky and skaa rebellions brew in the slums of Luthadel.
- Era 2 Campaigns: Scaled for character levels 3 through 9, these sessions shift the tone to a 20th-century-esque world of railways, electricity, guns, and law enforcement, reminiscent of The Alloy of Law and Shadows of Self.
3. Welcome to Scadriel
Recognizing that the Cosmere can be an intimidating labyrinth for newcomers, Brotherwise included a 24-page introductory softcover titled Welcome to Scadriel. Serving as a visual and narrative onboarding tool, this concise guide is built for beginners who may have never read a single page of Sanderson’s bibliography. It outlines the geography, social structures, and core conflicts of the planet, making it an ideal handout for player groups with mixed levels of familiarity with the source material.
| Product Name | Primary Function | Target Audience / Level Range | Release Date |
|---|---|---|---|
| Mistborn Handbook | Character creation, Allomancy, Feruchemy rules | General players & GMs (All levels) | November 4, 2026 |
| Mistborn Campaign Guide | Setting lore, multi-era adventures | GMs and players (Era 1: Lv. 3-6; Era 2: Lv. 3-9) | November 4, 2026 |
| Welcome to Scadriel | Visual primer and introductory lore | Absolute beginners / Non-readers | November 4, 2026 |
Official Statements and Design Philosophy
The creative philosophy behind the Cosmere RPG has always centered on fidelity to the source material paired with modern, accessible game design. In statements accompanying the rollout of the tabletop line, Brandon Sanderson has repeatedly emphasized his desire to see fans not just retell the stories of his books, but forge their own canon within his worlds.
"When we look at the Cosmere, the magic systems are essentially hard fantasy sciences," design leads at Brotherwise Games have noted during developer roundtables. "You cannot simply wave a wand and cast a spell; you have to ingest metal, track your burn rates, and manage your resources. Translating that to the tabletop required a system that respects the physics of Sanderson’s world while keeping the pacing fast enough for an engaging game night."
The decision to split the Mistborn content into distinct era-based level brackets (levels 3–6 for Era 1 and levels 3–9 for Era 2) reflects a deliberate narrative pacing. Era 1 is inherently compressed, high-stakes, and existential, necessitating a tighter level band. Era 2, with its broader socio-political shifts, industrial technology, and sprawling detective narratives, accommodates a wider developmental arc for characters.
Furthermore, the inclusion of the Welcome to Scadriel guide addresses a recurring challenge in licensed TTRPGs: onboarding players who love the mechanics of a game system but are intimidated by deep lore requirements. By creating an entry point that requires zero prior reading, Brotherwise is positioning the Mistborn TTRPG not just as merchandise for existing fans, but as a gateway to the broader Cosmere literary empire.
Future Outlook: The Horizon of the Cosmere Tabletop Space
As the November 4 release date for the Mistborn expansion approaches, the trajectory of Brotherwise Games and Brandon Sanderson’s tabletop venture points toward sustained, long-term expansion. The success of the initial crowdfunding campaign proved that the demand for high-end, professionally supported Cosmere gaming material is astronomical.
Looking beyond Scadriel, the framework established by the Cosmere RPG core rules opens the door for endless possibilities. Other foundational pillars of the Cosmere—such as the tropical, storm-battered world of Roshar, the political intrigue of Elantris‘s Sel, or the multi-dimensional magic of Tress of the Emerald Sea—stand as prime candidates for future sourcebook treatments.
For now, however, all eyes are on the mists of Scadriel. Whether players choose to don the mantle of an all-powerful Mistborn fighting to overthrow an immortal tyrant in a Victorian-esque dystopia, or strap on a six-shooter and a metal-mind to hunt down criminals in an era of rapid modernization, the 2026 expansion promises to deliver one of the most mechanically faithful and narratively rich adaptations in modern tabletop gaming history. Preorders are live now, setting the stage for a new generation of legends to be written across the centuries.
