IMO based on epi. 34 and that picture

AA= white bishop
Orb= White King
Shinn= Black Pawn
Kira= White Rook or Pawn that was knocked out by Shinn(Black Pawn)

why?
-Because AA was heading for Orb(the King) to support them
-Kira was "protecting" the AA(Bishop), so he was originally in-front of AA and "supposedly" knocked out by Shinn
-Orb is the White King IMO because it is Dullindal's(Black King) main/core enemy he has to defeat (or is in his way) so he can kill off the Logos

I may be totally wrong, but thats how I put it.
