A cinematic sci-fi fantasy sequence centered on a mysterious elevator traveling across universes.\n\n0–3s: A sleek, dimly lit elevator descends silently inside a futuristic skyscraper. A lone person stands inside, breathing heavily. The floor indicator flickers unpredictably.\n\n3–6s: Doors open — first floor: an underwater city. Glass walls reveal massive glowing sea structures, whales drifting between skyscrapers, and citizens walking in pressurized suits. Water pulses just beyond the barrier.\n\n6–9s: Doors close instantly, elevator shakes. Opens again — zombie apocalypse world. Burning ruins, fog-filled streets, silhouettes of infected moving in the distance. A survivor runs past the elevator in panic.\n\n9–12s: Another shift — fantasy kingdom. Golden castles floating in the sky, dragons circling above, knights riding through glowing bridges made of light. Wind carries magical particles into the elevator.\n\n12–14s: Final transition — Mars colony. Red rocky landscape, domed habitats, astronauts working under a pale sun, Earth visible in the distant sky.\n\n14–15s: Elevator doors begin to close slowly. The traveler looks overwhelmed as all worlds briefly flicker together in reflection on the metallic walls before the screen cuts to black.\n\nStyle: ultra cinematic, seamless world transitions, high-detail environments, dramatic lighting changes per world, realistic motion, sci-fi + fantasy hybrid aesthetic, immersive sound design feel, mystery-driven narrative tone.
