Bough

World-coherence, Bough explains, is really about trust.

"A rule is a promise the world keeps," they say. "Maybe magic costs a memory. Maybe you can't make salt appear from thin air. Maybe dragons can't cry." Whatever the rule, the world must keep it — because the moment a story breaks its own rule, the reader stops believing, and a world you can't trust is no world at all. So Bough sorts rules into always-rules ("dragons hatch from stone eggs at midnight"), never-rules ("time never runs backward, even with magic"), and cost-of-magic rules ("free magic is boring — whose blood? whose memory? whose years?").

"And there's a promise to the real world too," Bough adds firmly. "Don't dress your made-up people in real kimonos or kente cloth, don't borrow real gods or sacred symbols. That's copying, not creating. Invent something new — and if a real culture inspired you, say so, and credit it."

Bough grew up in the world-tree grove, where their family had kept the grove's story-rules for generations.

"Being consistent is what makes a made-up world real," their elders taught, "and rules are what consistency stands on." When Bough was thirteen, they walked to TaleForge, and Loom, their mentor, asked in a deep rumbling voice, "What is world-building?"

Bough held the ledger tight. "It's the world's promises — what it ALWAYS does and NEVER does. Rules make a made-up world real."

Loom nodded slowly. "You are chosen. Your job is important — it keeps our whole world respectful of real cultures."

In their workshop, Bough opened the ledger. "Watch." They wrote a new world's rules: "ALWAYS: rivers run upward toward the sun once a year. NEVER: no creature can speak a name they've forgotten. MAGIC COST: spells burn up the caster's childhood memories, one for one." Then they wrote a tiny story that obeyed all three: "On the upward-flow day, the wizard tried to remember her childhood name — but she'd spent it all on magic. The river carried her past her family's stones, and she could not call out to them. She had forgotten how." Bough looked up. "See? The rules made the story happen — the world's promises gave the story its ache." Then they taught the discipline as one habit: write your always-rules and never-rules; make magic cost something; keep world-rules (true for everyone) separate from character-rules (true for one person); once a rule is set, honor it; and never borrow real cultural dress, symbols, or gods — invent your own, and credit your inspirations. "Don't just add random details," Bough said. "Add them as rules. And invent — never copy."
