Did he [Vasher] actually come from Nalthis and not Roshar?
I’m not going to actually answer that one. Well I can answer that: yes he does come from Nalthis. It’s pretty obvious that the way that the Breath’s working, the reason he moved is because it’s easier to get Stormlight than Breaths, and Stormlight can fuel being a Returned like him. And so yes, he was born on Nalthis. Becoming Returned without being born on Nalthis would be really hard.
