My theories are up to WoT Book 10: Crossroads of Twilight. I've stopped maintaining this part of my website due to real life time management, but it's so huge and extensive, you might find it interesting anyway. Many of these theories are still unresolved as of WoT Book 13. Yes, I still the read the series, of course! I have to find out how it ends.
If you have additional observations or theories, please contact me. I might not respond, but I will read your email and file it away.
