Epic Arabian fantasy cinematic scene at night, vast moonlit desert kingdom with ancient domes and minarets, giant full moon illuminating golden dunes, mystical purple smoke swirling from a glowing magical portal on a rooftop terrace. A towering horned fire demon emerges from the violet mist, molten lava skin, blazing orange flames flowing from its head and body, glowing eyes, dramatic volumetric lighting, sparks and embers floating through the air. The demon unleashes a massive stream of fire across a palace rooftop while a brave young woman crouches nearby holding a magical artifact.
