a highly detailed photorealistic CGI rendering of a fantastical, gothic-style castle set against a dramatic sunset. The castle, with its tall, spires and intricate architecture, is situated on a rocky cliff overlooking a vast, misty valley. The castle is constructed with dark stone and features multiple pointed arches and intricate carvings. It has a grand, imposing presence, with a central tower that reaches high into the sky. In the foreground, a futuristic train with sleek, modern cars travels along a narrow, winding track that extends from the castle. The train is painted in a striking combination of red and white, with purple accents on the wheels and engine. The track is supported by stone arches that blend seamlessly into the castle's structure. To the right of the image, a large, white airship hovers in the sky, its sleek design and large fins contrasting with the gothic architecture below. The sky is filled with dramatic, golden-orange hues, casting a warm glow over the entire scene. The horizon is blurred, suggesting a misty or foggy atmosphere, adding to the ethereal and fantastical feel of the image.
