A majestic floating island with a grand fairytale castle, surrounded by lush greenery and a serene pond. The island hovers in the sky, with a beautiful starry night background. A glowing full moon and a vintage hot air balloon float nearby, adding a magical atmosphere. The castle has tall, elegant spires, golden accents, and intricate architectural details. The scene is dreamy, fantasy-themed, and highly detailed, with a soft ethereal light illuminating the landscape.
