Two Little Mice has opened crowdfunding for Twilight Sword: Monster Book, the first supplement for its fantasy tabletop role-playing game made in collaboration with Free League Publishing. The BackerKit campaign began on 10 November 2026. The new book gives game masters tools to create their own monsters and gives players rules for making gear from the creatures they encounter. Campaign announcement

At a glance

  • The expansion adds monsters, bosses and a character option that starts play with an animal companion.
  • Existing groups can back the new material on its own. Newcomers can choose a pledge that includes the core books.
  • The campaign is scheduled to close on 3 December. Physical rewards are estimated to ship in October 2027.

What the Monster Book adds

The supplement brings more creatures and bosses to Radia, the setting of Twilight Sword. A monster-building tool lets game masters create creatures of their own, so the book can support a home-written adventure as well as provide ready-made encounters. The crafting rules give groups another way to use what they find during those encounters by turning materials from monsters into equipment.

The book also adds a new Way, the game's term for a character path, that lets a player begin with a beast companion. That gives players a character option to consider at the start of a new adventure, alongside material that a game master can bring into an existing campaign. Monster Book campaign

Where to start if you are new to Radia

In the base game, players take the roles of Champions who travel through Radia and restore hope by helping its inhabitants. Free League lists the game for two to six players aged 14 and up. The publisher offers a Starter Set and a separate Core Rulebook, so a group interested in trying the game can look at the starter material before deciding whether it wants the expansion.

BackerKit has tiers for both audiences. Digital Monsters focuses on the new content in PDF form, while the Core Trio includes three hardcovers and the corresponding digital material. The Hero tier combines the earlier collection with the new material. That distinction matters if you already own the core books and only want new encounters or character options.
