Player's Handbook · Chapter 5

Lore, Chunks, and Truth

Package provenance — this chapter ships with the Ontology & Structure Engine. Provenance tag: source-ontology-project. When loaded into a new world, grep the tag to find the engine's templates and instructions.

The engine remembers the way a good memory does: one fact at a time, with a note on how true it is and when it was true.

One file, one fact cluster

Each lore file holds a single cluster of meaning, small enough to be retrieved whole. The pattern: one town, three files —

  • thornhollow-place (geography) — what the place is
  • thornhollow-lore (history) — what happened
  • thornhollow-state (culture) — what is true right now

When a file outgrows one cluster, split it and keep the pieces linked.

The recall surface

Every lore file carries a summary — one self-contained sentence — that tells a reader (or a search) whether this is the file they want. keyFacts atomize the cluster into standalone facts. The body is the chunk itself; tags are the recall vocabulary; domain is the axis and the folder it lives in.

Truth levels

LevelWhat it means
canonSettled; the world runs on it
establishedWidely accepted; the default
rumorSomeone believes it; recalled as hearsay, not fact
mythWhat the world tells itself
theoryAn interpretation
retconnedOnce believed, since overturned

This is your misinformation toolkit. Seed a rumor about the fog, and retrieval presents it as rumor until you promote it.

Time

Every claim carries an era. "The capital is besieged" from the last war must not be recalled as current truth. Current truth lives in -state files; historical truth lives in history files.

Link, don't restate

A fact lives in exactly one file; other files reference it. That rule keeps the memory from rotting — no duplicated facts to go stale.
