Draw an image that depicts an elderly person with a long white beard, dressed in a blue robe, sitting at a wooden desk in a grand, medieval-style room. They are writing in a large book with a quill, illuminated by candlelight. The room features tall stone columns and a large, intricate stained glass window with celestial designs, giving the scene a mystical, scholarly atmosphere. This setting suggests a wizard or sage, possibly in a fantasy context.
