If you check out the updated character section, you will find that it hasn't been fully updated with EVERY story and novel. This is because i haven't managed to get my hands on every one. And yes I know i havent really finished Exile's Song and Traitor's Sun, but that's because I didn't add the characters to my personal list before i returned them to the library. I have gotten a few anthologies that i will add ASAP.
Also, many characters (like Regis and Lew) appear in multiple novels, and I figure this list is cramped enough, so I will only write about them once. I will try to give them a list of books they also appeared in though, but as i keep reading they keep popping up in unexpected places. if u find a book i haven't added yet, ADD IT PLZ!!!
