-White luxin seems to have something to do with the blinder's knife, but how and in what way? Ironfist seems to have the bit that Dazen(Gavin) made at the battle of Garriston (book 1).
-Grinwoody/Old Man of the Desert's plan has been seemingly revealed: have Dazen kill Orholam(magic) with the blinder's knife and then let the locusts take over the world since there will be no one around to oppose them since magic will die.
-Why is this book called Blood Mirror? I was hoping a new mirror (nine kings card maker) would be revealed and that does.... something. Instead we got nothing.
-Pretty much nothing happened with Liv.
-No word on what the White King is doing, other than the Banes are ready to sail? Banes that sail around is also fucking stupid IMO.
-Why the White King? He didn't have enough names? Omnichrome, Color Prince, Lord Rainbow (Faggot), etc etc
-I bet Gavin isn't really dead. Dazen never brought his body back, and it seems black Luxin doesn't kill, merely remove memories and cause madness? Or does it kill? It seems unclear to me. Probably going to be handwaved with "That's black luxin for you, lol"
That's all off the top of my head.
