Alright guys, I went to the signing and have a good three and a half hours of audio. If anyone wants to transcript, be my guess.
So. Asked a few things: First of, Warbreaker was written as a sort of prelude to the character of Zahel.
Aluminum does not give an atium shadow (Whoo!)
Nightblood is a Shardblade, that is super powerful and twisted.
If Kelsier's Cognitive Shadow went to the Forests of Hell, he would be a shade.
If Laras's Cognitive Shadow went, he would be a shade.
If a Seon went, they would be a Shade.
Will post audio when I figure out how.
