Sage of the Emerald Arcana

Prompt:  An elderly wizard with a long, flowing white and gray beard, piercing deep-set eyes, and a stern, wise face. His hair is shoulder-length and silvery-white, swept back from a high forehead. Skin tone is pale with a hint of an ethereal glow. He is dressed in an ornate, emerald green robe with intricate golden patterns and symbols, over which is a deep maroon and gold-trimmed cloak with circular, gem-encrusted brooches at the joining points. A prominent amulet with a glowing purple center dangles from his neck, exuding mystical energy. His left hand is raised, fingers curling to channel a vibrant green magical energy that spirals in a straight line from his left hand to his right hand which is raised above his head and emanates a radiant golden glow. The background is a magical swirl of green and golden hues, suggesting otherworldly powers at work. The lighting is dramatic, with a glow emanating from the source of magic in his hand, casting light on his face and casting the rest in comparative shadow, giving the scene an overall mystical and powerful atmosphere.
