World Structure

World structure is the entry-level guide to how a fantasy or wuxia world is built. Where individual races, regions, and entities are catalogued elsewhere, this page asks the more basic question — what holds the world together, and what makes it different from another world.

Every fantasy world rests on the same handful of structural questions. What are the laws of power? Who lives there? Where do they live? What classes and roles exist? What entities transcend the ordinary? What history shaped the present? What artifacts persist across eras? These foundations decide what kinds of stories the world can tell.

MoonWiki's world hierarchy splits into eight axes that map onto these foundations. This page walks the big picture and points you at the right entry.

Core characteristics

The defining properties that set this category apart from others.

  • Structural
    What holds a world together at the base layer.
  • Cross-work baseline
    Provides a common map across different worlds.
  • Beginner-friendly
    Easy on-ramp for understanding worldbuilding.
  • Story-shaping
    Decides what kinds of stories the world can tell.

How it differs from neighboring categories

Even within the same family, each category has a distinct character. Comparing side by side is the fastest way to grasp the differences.

World Structure

How a world is built at the base layer.

Power Sources & Laws

The laws by which power operates in the world.

Races

Who lives in the world.

Nations & Regions

Where they live.

Best for first-time worldbuilders and cross-work comparison.

  • Cross-work comparison
    Comparing the structural foundations of different worlds.

The eight axes of world structure

MoonWiki uses eight canonical axes.

World Structure

The base layer of how the world is built.

Power Sources & Laws

The laws by which power operates.

Races / Regions / Classes

Who, where, and what role.

Deities / History / Artifacts

Transcendent entities, history, and persistent objects.

Limits of world structure

Foundation pages trade depth for breadth.

  • Abstract
    Specific races, regions, and entities live on the individual pages.
  • Varies by work
    What 'world structure' even means shifts across works.
  • Supplement needed
    Pair with axis-specific pages for the full picture.

How worldbuilding develops

Worlds grow from base structure into full population.

Base layer establishes the laws of power, the races present, and the regions that hold them.

Mid layer adds classes and roles, transcendent entities, and history.

Top layer brings in artifacts that persist across eras and the events that shape them.
