[Syrlya shakes his head.] No, they refer to different specializations of magic. You start at Pawn and will find yourself suddenly prepared to study the magic of a King, Queen, Rook, Knight, or Bishop. Queens and Kings have the greatest reserve of magic, but the resulting spells are very different between them. Ah, even those of the same rank may specialize even further!

It--may be overwhelming if you are not used to anything like it, but I think you will understand it.
