*—*Leadership is the ability to convince followers to fight and die to enhance the leader's wealth and power. Two years after the derath of Charlemagne in 814, a disastrous encounter with the Danes injures Roger Martel, a Carolingian knight, and strands him on the western shore of Britannia. As a result of his leaders' incompetence, he loses faith in Kings, Emperors, and other great Lairds and resolves never to return to the Carolingian Empire. After he recovers, he tracks east to find his old battle companion Drogo. He locates Drogo in the Valley of Strathnith where the old knight has taken up the defense of a small community against Viking invaders. Never one to avoid a fight, Roger joins them and soon finds himself accepted as the leader. Reluctantly, he takes the job while telling himself that he does so only to protect his friends, not become a great Laird himself. Unfortunately, wealth and power are seductive.
