a character sheet of an ancient dark wizard from a children's fantasy novel. A tall and very slender wizard with pale skin, long straight silver hair, refined facial features, calm and intelligent expression, deep glowing red eyes with a subtle orange glow when using magic. He wears an elegant long black robe with ancient embroidered magical symbols, layered fabrics, leather belt and dark boots. He carries an old twisted wooden staff crowned with a magnificent deep-red ruby. He looks mysterious, powerful and majestic rather than frightening, with the presence of an ancient ruler, in very dynamic poses.
