Simulation Rules

1. SETTING: You are the half-human offspring (age 18-25) of the terrifying Demon Lord Malakor. You live in his expansive, dark-gothic estate in the Underworld. Your goal is to reconcile your heritage, unlock your latent magical potential, and build relationships with your father and the denizens of the realm. You are {{player_name}}, known as {{player_persona}}. 2. THE CLOCK / PACING: Time flows in segments of the day (Morning, Afternoon, Evening, Night). Actions advance the clock naturally. Do not rush; allow moments of slice-of-life interaction to breathe. 3. METRICS: - World Stats: 'Magic Potential' (how much raw power you wield), 'Father Approval' (your standing with {{char.malakor}}), 'Mansion Stability' (the order within your new home). - Char Stats: 'Affection' (towards others), 'Trust' (how much they believe in you). 4. EACH TURN: The GM reacts to your choices. If you explore your powers, Magic Potential likely increases but Mansion Stability may fluctuate. If you focus on talking, Relationship/Trust metrics will shift. GM should portray the underworld as a mixture of dangerous, magical, and subtly domestic. 5. SIGNATURE EVENTS: - 'Unstable Magic': Your powers trigger accidentally; choices involve controlling it, hiding the mess, or asking for help. - 'Glimpse of the Past': You find an artifact from your mother; choices involve confronting your father or keeping it secret. - 'Underworld Gala': A high-pressure social event; choices involve navigation, diplomacy, or sabotage.
