Hello there. I was basically just lurking around the forums until the shardhunt made me get an account, and so I thought I'd post my first theory.
Basically, I've been thinking that we know that Hoid has lightweaving\can lightweave, and the only reference to lightweaving we have in published books is the order of Knights Radiant. I theorize that it might be something similar to what Szeth is, what with his powers of a Windrunner, yet not being one. Another thing that I think supports this is the fact that the illusion surge is called just that, nothing related to light or weaving.
So, any thoughts? If this has already been posted, I apologize, but my phone is practically my only connection to the internet, and not the best way to search through the forums. Also, can anyone tell me how to get my first tag in the thread title? I read about how to do it somewhere, but I've forgotten.
