I'm new here so I realize I'm a little late to the party but I was rereading OB recently and there is a scene right at the end of chapter 38 inside one of the visions with Dalinar, Navani, and the Stormfather sitting in a cave where the 9 Honorblades are stuck in the ground. They just happen to be talking about the Heralds when a Shin looking man stumbles in, kneels before the circle of blades, then says only 2 words to Dalinar in Honor's voice. "Unite Them"
I'm convinced, because Honor wouldn't have known the Everstorm would happen, that he meant for them to unite the Heralds in order to yet again drive back the voidbringers.
