The kinds and their odds are data the game hands in; a port asks whether this machine owns the world, the hour, the night, the odds from a kind, what the story wants of the sky (a front, a hold, a clear night), the front's kind and length, and a seed. Its own dice; a new spell, a clearing, lightning and a wanted front are facts on weather_facts(); its own save section. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
