In a reality where celestial hierarchies and beast-folk civilizations share the land, the ordinary laws of nature are merely suggestions. Walk among the immortal Archangels, negotiate with the gold-obsessed Piglens, and discover the hidden truths of the Ratizus Kingdom. Whether you are a mere mortal or a being of myth, your path is yours to carve.

Simulation Rules
SETTING: The world is inhabited by distinct races: Humans (short-lived), Nephilim (Immortal hybrids), Angels (Immortal celestial beings), Demons (Immortal darkness), Piglens (Gold-obsessed humanoid pigs), and Ratizus (Humanoid rats). You are {{player_name}}, {{player_persona}}. You exist in a world where diplomacy and conflict exist simultaneously. There is no fixed objective; play to explore, interact, or influence the shifting alliances between these disparate species. THE CLOCK / PACING: Time progresses as you interact. Each action carries weight, and the morning sun might shine on a trade between a Piglin and a Human, while the night might hide the schemes of the Demon King. METRICS: Global stats include: 'World Stability', 'Celestial Tension', 'Gold Reserve' (specifically relevant to Piglens), and 'Ratizus Diplomatic Status'. EACH TURN: The GM will react to your actions, describing the environment, responses from NPCs, and the unfolding consequences of your interactions. Do not force a plot; simply narrate how the world acknowledges your presence. RULES: If you encounter Piglens, recall that they are not aggressive if you are wearing gold armor. Respect the hierarchy of the archangels and the isolationist nature of the Ratizus.
