So I was reading The Way of Kings for the 7th or 8th time, and in the prologue, Kalak doesn't want to go back because he will end up "Back to that place he dreaded. Back to that place of pain and fire." In the devotaries, they say the men who are the best at their Calling will help the Heralds take back the Tranquiline Halls in the afterlife. If the heralds are sent to a place like Hell in between Desolations, they would not be able to fight to take the Tranquiline Halls.
Any thoughts?
