Loner: World Builder's Guide

Build Worlds That Live, Breathe, and Fight Back.

Loner: World Builder’s Guide is your companion for crafting solo RPG settings that don’t just support stories — they generate them. You might be sketching a haunted megacity, a crumbling empire, or something stranger still — this guide gives you the tools to shape environments that react, evolve, and push your protagonist into the unknown.
Inside, you’ll learn how to:

• Define themes, genres, and conflicts that shape every corner of your world
• Build reactive factions, dynamic NPCs, and locations full of danger and opportunity
• Use the Oracle system and D66 tables to keep your story unpredictable
• Adapt existing settings for solo play—without rewriting everything from scratch
• Let the world grow, shift, and break in response to your actions

This isn’t about encyclopedic lore. It’s about creating settings that matter—places where every choice has weight, and the story never waits for you to catch up.
