Picture a regal alien diplomat standing tall, adorned in elaborate, flowing robes that shimmer like stardust. The fabric showcases intricate patterns of constellations, morphing colors under the soft glow of distant stars. Their elongated features are softened by an expression of wisdom and calm, and vivid bioluminescent markings pulse gently along their skin. Behind them, a vast interstellar backdrop hints at a galactic council meeting, filled with vibrant celestial bodies.
