From their announcement:
Ranking errants, veterans of countless crusades and incursions are chosen to lead their brother-knights in their battles abroad. Pure in heart and thought, they are trusted to carry out their holy mission no matter the bloody price. Their dedication and inspiring example is so great that the knights they lead will make any sacrifice to ensure the success of their sacred missions. Accompanied by the battle standard of the Order of Exemplar, the errants are inspired to the greatest valor, letting no obstacle come between them and the heathen enemy.
