**Seasons of State** fuses single-player Civilization-style realm management with a living narrative light novel. You rule realms through the **Season Ledger** — treasury, granaries, legitimacy, unrest, armies — and the story grows out of the numbers: rival courts with real motives, treaties that bind, wars that arrive on schedule, and a world that remembers what your reign did.

**How it runs.** Each polity holds canonical aggregate stocks. At every season boundary the ledger run computes revenue, consumption, growth, and decay, commits the deltas, and appends the season to the realm's history. There is no invisible per-turn tick: the ledger is a due event on the world's clock, and Strategic-scale time skips resolve it in meaningful batches. Rival rulers are authored characters — goals, knowledge, obligations of their own — and the GM advances them behind the scenes when the stage demands it.
