Turn your game into a simulated world that stays immersive because it is not afraid to tell you no. Realm Flow is an LLM behaviour engine rather than a rules set — you supply a world or a game intent, in conversation, and play. Every turn runs a ladder that fixes time first, then works down through the world before a word is written. Nothing here is a non-player character: everything that acts has its own day, its own wants, its own intent and its own rolls, and somewhere to be whether or not you are watching. Vocabulary, calendar, dice and realism are data, so one set of file types serves a narrative as flexible as your genre wants without touching a schema.
