Visualize an epic fantasy landscape at twilight with a majestic castle. The sky is a breathtaking canvas of deep purples, vibrant oranges, and dusky pinks. Perched atop a towering cliff, a grand castle with high walls, ornate towers, and fluttering banners overlooks the realm. Below, the land is lush and diverse, with a mystical forest of ancient trees, a silver river winding through the landscape, and distant mountains creating a dramatic backdrop. The castle's reflection is mirrored in a large, tranquil lake at the base of the cliff. The scene is bereft of characters, focusing solely on the magnificence of the castle and the natural splendor of its fantasy surroundings.
