How to make an AI demon king or dark fantasy drama

Quick answer: A demon king drama is a bargain: a mortal who needs something, a ruler of the dark who wants something back. In SceneMixer, Step 1 builds the underworld: Dark Asura (black and gold, obsidian, bone totems, fire and lava as the light) for an Eastern demon realm, Gothic Dark for a Western one, with Dark Path Robes or Gothic Court to dress the court. The demon king's true form is a state of the character, revealed when the story needs it.

Horns, forms and curses

  • The true form is a state. Horns, black eyes, the fire behind him: one character, two states. States.
  • A curse mark that spreads is a state per stage, or a prop if it is an object (a cursed ring).
  • Write the light. “Lava light from below, gold edges on black pillars” gives a dark throne room something to see by. Describe the cause.
  • Fear without gore. Graphic injuries are blocked; menace lives in the voice, the silence and the size of the room. Content rules.
