Same tag-based chassis and Chance-vs-Risk Oracle underneath, but this one is aimed at the person who wants to build a world and then populate it with things worth asking an Oracle about. It's the workshop manual for the rest of the line. ## Setting The book isn't a setting so much as a factory for them. It walks you through building one in broad strokes rather than a full blueprint — theme and genre, a central conflict, tone and mood, and the Protagonist's place in it all — then fills it with character archetypes and NPCs, locations, story hooks, and random events. There's a whole chapter on adapting an existing published setting to run on **Loner** without its group-based assumptions. And the back half is the really useful part for tinkerers: crafting your own D66 random tables, with appendix templates and guidance for remixing those tables across different genres. It's the book that turns the solo player into a game designer whether or not they intended to be one. The throughline in 4e is that the setting should stay alive after you roll the dice. Factions get agendas, actions get consequences, nothing sits still — the world is supposed to move on its own, not just when the Protagonist is looking. ## Mechanics The core remains the shared Loner Oracle, and the World Builder's Guide makes heavy use of **D66 random tables** — roll two d6, first is the tens digit, second is the units, and a 36-entry grid of inspiration falls out. The book teaches you to build and remix those tables so your custom world has native oracle support rather than borrowing someone else's. It's the most meta of the line: instead of giving you a genre, it hands you the lathe and the raw material. In 4e the guide leans on a couple of new optional tools from the core rules to keep that world reactive. **Challenge Tracks** give you a four-box progress record for arcs too large to resolve in a single oracle roll — open one for a faction closing in or a disaster unfolding in slow motion, not just the Protagonist's goal. And the **Living World** procedure is the post-adventure checklist that updates NPC and location tags, notes what's still unresolved, and keeps the fiction from quietly resetting. Same dice, same Oracle — pointed at the setting instead of the character. ## Editions - **3rd edition (2025)** — the original supplement, released May 2025. *In the library.* - **4th edition (2026)** — released September 25, 2026, reorganized and brought in line with the 4e core rules; the Living World procedure and Challenge Tracks give its setting tools a mechanical tracking baseline. *In the library.* ## References - [Loner: World Builder's Guide (4e) - DriveThruRPG](https://www.drivethrurpg.com/en/product/522155/loner-world-builder-s-guide) - [Loner SRD (free full text) - Zotiquest Games](https://lonersrd.zotiquestgames.com/) - [Loner - Official Website](https://loner.zotiquestgames.com/)
