Sophia is easy. Just look up her full name. Don't worry; we're on no shortage there. Raphael is generally considered an angel of peace, healing, and magic. I also think we need to lay down some basic criteria for the rest of the Upper Planes. Who's in charge of the angels, and are there any other members of the Court of Stars? The guardinals are covered, but I always thought they weren't really up to the task as exemplars of NG.
