A note on spoilers. Characters are listed under the book in which they first appear, and descriptions avoid major plot resolutions. Even so, reading about a later-book character can hint at where the story is heading — if you'd rather discover everyone as you go, consider starting with the Principals and the section for the book you're currently reading.
