The Christian armies of Spain are on the rise and are taking back the land controlled by the Taifa States. All seems well and the star that is Rodrigo de Vivar continues to rise. All of this ends when King Fernando dies, and his heirs begin a self-destructive civil war. Only the knight respected by both Christian and Muslim alike, the man known as El Campeador can unite the troubled land of Spain.
We see the troubles of Spain through the eyes of the man who trained Rodrigo, William Redbeard, and it is through him that we see the effect the civil war has on the ordinary people. When King Sancho is murdered then all hope seems to disappear and Rodrigo and Will Redbeard have to choose which side they are on.
