SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

World-building logic provides a structured approach to creating consistent fictional settings, helping authors avoid logical gaps and arcane contradictions by applying proven frameworks such as Brand's Pace Layers and Sanderson's Laws of Magic.

Core Features & Use Cases

  • Internal consistency engineering: Apply pace-layer theory and magic-system constraints to build believable worlds.
  • Guided world-building workflow: Step-by-step guidance for establishing Site, Structure, Limitations, and Environmental Storytelling.
  • Use Case: Develop a fantasy realm with a coherent magic system or craft a sci-fi city where technology and culture evolve in harmony.

Quick Start

Define the setting's geography and deep traditions, then list three limitations and test a second-order effect.

FAQPage Schema
How do I build internal consistency in a fantasy world's magic system?

Apply Sanderson's Laws of Magic to establish coherent rule-sets and limitations. This structured world-building approach ensures internal consistency in magic systems, preventing logical gaps and arcane contradictions during narrative design.

What is the best way to apply pace layers to fictional world-building?

Use Brand's Pace Layer theory to structure site geography, deep traditions, and environment. This framework guides the establishment of layered world-building, helping authors craft believable worlds where culture and environment evolve logically.

Can I use this world-building workflow for sci-fi city development?

Yes, this guided world-building workflow supports sci-fi city development. The internal consistency engineering process ensures technology and culture evolve in harmony through structured environmental storytelling and logical testing.

How do I test second-order effects in a magic system?

Define the setting's geography and deep traditions, then list three limitations to logically test interactions. This guided workflow helps you evaluate second-order effects in magic systems, ensuring your narrative design remains coherent.

Why does my fictional setting have logical gaps and arcane contradictions?

Fictional settings develop logical gaps and arcane contradictions when world-building lacks structured internal consistency frameworks. Applying pace-layer theory and magic-system constraints helps identify and resolve these structural errors during development.
