Virtue of the Penitent

'Following the loss of his beloved to the curse of a hag, Duke Corduin of L'Anguille became known as the Hermnit knight. Though when called to arms, he would always return to fight for his beloved king.'
The Knight is Stubborn, though he may never join any friendly units. He may not take any magic items, nor may he ride a Hippogryph or a Royal Pegasus.
