Sir Gwayne is Queen Ysabelle’s current Knight Marshall – a new position created after the treachery of the Knights Coronet. The Knight Marshall is the ultimate commander of all the other orders – the Coronets, the Griffons, the Wolves, the Lancers, the Swans, and the reformed Dragons.
Originally the position was offered to Luther, but he declined and suggested Sir Gwayne, a long time friend, and someone unswervingly loyal to crown and kingdom.
