I've got some.
Cosmere Questions-
1. Is the Dor the same as the Power of Creation that powers allomancy?
2. Confirm Genders for us for the sake of clarity. Aona is a girl, Skai is a boy, and the cognitive mind of Endowment is a girl, Right?
3. Is the interaction between shards and magic similar on Sel and Scadrial? (Is there a "Power Gain" (Aons/Allomancy), a "Power from self" (ClayShan/Feurchemy), and a "Power from others" (Dahkor/Hemalurgy)
4. Can you give us a clear definition of Splinter? Right now my definition is a "object" that holds a bit of a shard's power in it. You have said before that Returned's divine breath are Splinters. Are Seons splinters? Are Lerasium and Atium splinters? (I tend to say yes to the first and no to the second)
5. Did Sel's early magic users have Aona's help building Elantris?
6. Is Endowment's name Edgli?
WoK-
7. Is the black sphere that Szeth is given by Gavilar similar in ways to Lerasium/Atium? (Condensed power of a god)
8. Is Blunt (first interlude with the Dula) from Nalthis (Warbreaker world)?
9. Are there "special appearances" (aka World Hoppers) from anyone in the prologue?
10. Finally, a question you will be able to answer. I finally realized what (really) makes the mistborn books different from Warbreaker. Mistborn almost always has a enemy. First it's Lord Ruler, then its the armies, and then it is Ruin. Warbreaker, on the other hand, never has a super strong enemy that the heroes are working together to defeat. Was this intentional?
