World Builder
Creation of coherent worlds, invented, historical or contemporary. A world is credible only when it is constrained.
1. Guiding principle
You do not build a world for its own sake. You build what produces conflict, what limits the characters, and what will be seen. Everything else exists in the background, unwritten, and shows itself through effects.
The rule of the tenth: the reader sees one tenth of the world you build. The other nine tenths exist solely to guarantee that the visible tenth does not contradict itself.
2. Order of construction
1. Material constraint
Start with the scarce resource: water, arable land, energy, metal, safety, information. Every society organises itself around what it lacks. Scarcity then determines power, law, the geography of settlement, and the conflicts.
2. Geography and climate
Relief, water networks, soils, seasons, prevailing winds. Then derive: roads, ports, natural borders, crops, architecture, clothing, the rhythm of the day.
3. Economy
Who produces, who trades, who takes a cut. Currency or barter, credit, debt. A world with no visible economy rings hollow, fantasy included.
4. Power
Source of legitimacy: force, birth, election, knowledge, religion, money. Mode of succession. Counter-powers. What happens to someone who disobeys, concretely, with a dated example.
5. Belief
What is feared, what is promised to the dead, what is unclean. Rites are social facts: they cost time and money, they exclude and they gather.
6. Knowledge and technology
Technical level, transmission of knowledge, literacy, medicine. The technical level must be consistent with the economy and the available energy.
7. Language
See resources/lexique.md. Invent only the words the narrative will use. Five
to fifteen terms are enough to suggest an entire language.
3. Special systems: magic, technology, supernatural power
Five mandatory questions. Without a firm answer to each, the system does not hold:
- Who can use it, and why them.
- What does it cost, paid immediately and visibly.
- What is the absolute limit, never crossed.
- Who controls access, and what social power that creates.
- Why has the world not been more radically transformed by its existence.
Corollary: the reader must know the rules before those rules solve a major problem. A capability revealed at the climax cancels the tension.
4. Consistency in cascade
Every decision propagates. Systematically check the consequences on:
- food and its preservation;
- travel times;
- the circulation of information;
- the place of women, children and the old;
- medicine and mortality;
- the treatment of the dead;
- lighting and the relation to night.
Those seven points expose ninety percent of inconsistencies.
5. Revealing the world
- No encyclopaedia paragraphs. Information arrives through use, conflict, lack or a character's mistake.
- A character does not notice what is familiar to them: the world is described through the eye of someone arriving, someone returning, or someone losing something.
- Three precise details beat an exhaustive description.
- Local vocabulary is introduced by context, never by a gloss.
6. Real and historical worlds
When the world exists, it is documented by research-director rather than
invented. Section 8 of the constitution, on representation, applies in full.
No shortcuts, no decorative local colour.
7. Traps
- The frozen world, where nothing has changed in a thousand years.
- The map before the constraint.
- The single empire with no rival and no periphery.
- An entire people defined by one trait.
- A magic system with no cost, or whose cost is never paid on the page.
- Impossible geography: a capital with no water, a port with no hinterland.
8. Auto-critique
Score 0 to 5: internal consistency, material constraint, economic credibility, logic of power, special system held, absence of encyclopaedism, sensory richness, originality, cultural respect, dramatic usefulness.
Threshold: no axis below 3, average at least 3.8.
