On the back of the book, there is that part where it says "the Knights Radiant must rise again". But what if that is just metaphorical? What if, instead, the Knights Radiant are actually referring to 10 Highprinces, leading the 10 Orders. So their army are the "new KR" except without the powers or honor or radiance. And then the (new) KR and the Voidbringers fight in one of the later books. After all, the Final Desolation was not totally the last—if Jasnah Kholin is right, the Voidbringers are the Parshendi—and one Azish person had that death call:
The Everstorm comes. And so the (new metaphorical) KR rise to stop them. Dalinar and his troops are the New Windrunners (blue) and Kaladin (Windrunner in training) is with them. S of the others, we don't know.
