I think he's a radiant... or was a radiant and is now an oathbreaker.
Or... what if he has a nahel bond with one or more of the Unmade? Perhaps he has a bond to Mishram?
...when Ishar doubted him as a Herald, so I guess that means I deserve mine for calling it 5 years in advance
I just finished WaT to find that my old Theory turned out to be (mostly) correct, my shame is that I never expanded on it!
Hoid has mentioned before that he has goals. Does Hoid have a specific acheivable ultimate goal which these goals serve, or is his mission one which he expects to be undertaking forever?
Ultimately I'd probably get RAFO'd... but I think it might promt some interesting comments from Brandon.
Dragon Steel and Aluminum could be one in the same. A before the shattering and after the shattering kind of thing... It would explain why it's so rare.
Scars and injuries that you think are part of who you are don't seem to be healed by stormlight. Feruchemists might be too used to the act of storing for stormlight to "heal" the effects of them storing an attribute.
I don't know who they will be... but there is deffinitly a flute that is a key element in the stories. The "dark wood" flute given to Kaladin by Hoid.

I like the worldhopper idea better...I can't think of any mechanics that have been put forward in Roshar that would make it easy for her to staple herself to reality the way Thaidakar did... I guess maybe a bondsmith could do it for her?
She would make a GREAT mafia boss... imagine all her personailities taking on different roles in the organization without people realizing it's their leader they are with.
You could probably do anything a shard could do... with the limitation being that you basically need to write code each time in order to do it. That's a pretty big limitation... but it is powerful at a slow pace.
