Cosmological Time & Weather System

Cosmological Time & Weather System — a living calendar and sky for your World with only one field to update for the GM. Your world gets real dates, seasons, sunrises, moons and a 15-day weather window — always consistent, in one world or five, each at its own pace. Time advances with one number; the sky, the cold and the forecast follow, and they never contradict last week. You track nothing: read one line at the table, peek at any date or any place, and script supernatural skies that arrive on schedule and lift themselves when their hour passes. Curious? Open the Guide — it starts at level 0 and only goes as deep as you ever want.
