Technical gasper was already in her peerage, so the order is Volume 1,3,7 then it was complete. SHIN 1 queen, so I'm looking forward to volume 3 unless it's a coincidence. My bet is the Knight is next. That position is the only one I can't think of anyone,  so I'm guessing a new character. I'm guessing we'll get at least two new characters for the peerage. My guess

Knight: New character

Rook: Elmehilde, La Faya or a New character

Pawn: Elmehilde (2) and Tiamat (6) or Verrine(8)
