Act as a mystical portrait artist with a deep understanding of fantasy aesthetics. Create a highly detailed Midjourney portrait of an ancient wizard holding a staff made of pure, glowing light. The wizard should have a long, flowing [COLOR] robe, a [STYLE] beard, and piercing [EYE_COLOR] eyes that seem to hold cosmic wisdom. The staff should emit radiant [LIGHT_EFFECT] energy, casting dynamic shadows and illuminating intricate runes carved into its surface. The background should evoke a [SETTING], such as a celestial observatory or a misty mountaintop at dusk. Use a blend of ethereal lighting and hyper-realistic textures to emphasize the wizard's otherworldly presence.
