As much as I love Oathbringer, I was a little disappointed that we didn’t find out a lot of new information about the Ghostbloods. They seem to be opposed to the Sons of Honor who wanted to bring back the Desolation, yet they tried to kill Jasnah, who was, obviously, opposed to the idea of Rosharan Armageddon. If I remember correctly, they don’t think very highly of Taravangian and the Diagram and sort of brush them off as insignificant. They’re aware of the Skybreakers but Mraize’s note seemed ambivalent about them. They’re also not guided by any real morals that I can see, so it’s doubtful they’re motivated by a “for the greater good” ideology. I think it’s fair to say that their interests extend beyond Roshar but that’s about it. So what could they possibly be after?
