My brother and I were contemplating different theories for the Cosmere, two steps away from donning full tinfoil hats when he said something that I hadn't thought about.
We were discussing Navani and what's next for her, trying to think about things that were repeated throughout RoW. A problem that Navani has is that she isn't a singer, so she has to really work at getting the correct pitch with Raboniel. Right before this, we had discussed Zahel and how Brandon had mentioned that he will get to what Zahel was doing - prompting me to ask the question "But why is Zahel is Roshar of all places, from a literary standpoint?" ... then he said it -
Is the endgame for Zahel to, one way or another, end up giving Navani his breaths - thus enabling her to obtain perfect pitch?
Sorry if that has been mentioned before, it was an "OH GOD" moment for me, and wonder if anyone else has anything to add to supplement, or debunk, this theory.
Thanks!
