Create a dark fantasy artwork inspired by the style of Luis Royo

Create a dark fantasy artwork inspired by the style of Luis Royo. The scene should be eerie and evocative, with a mystical and melancholic atmosphere. Include a powerful central figure, such as a old male vampire with long hair and long beard, set against a detailed gothic backdrop with elements of fantasy like supernatural creatures, ancient castles, and desolate landscapes. Use a palette of dark and deep colors, and emphasize texture and dramatic lighting to capture the essence of Royo's style.
