Questioner [PENDING REVIEW]
If someone from, say, Roshar, traveled to the world of Warbreaker, do they have Breath?
Brandon Sanderson [PENDING REVIEW]
No, they do not. And if someone from the Warbreaker world leaves, they will still have their Breath. They would not register as being a Drab for people who are looking. They would register as Option C. Particularly someone from Roshar, who is from a primary Shardworld, is slightly Invested.
