In 1084, the bitter struggle between the Pope and the Emperor for supremacy in the Holy Roman Empire was raging. Each tried to win the princes over to his side. After the humiliation inflicted on his predecessor by Henry IV at Canossa, the newly elected Pope Urban II comes up with a bold plan: he wants to pacify Christendom through a common goal - under his leadership, the knights of Europe are to reconquer Jerusalem. Remy d'Aretin, the "Grey Cardinal", pulls the strings, the enterprising squire Rinat of Sitten becomes the chronicler of the gripping events. When the Pope's knights gathered at Clermont in 1095, a secret brotherhood also took the oath. It is the nucleus of the late Knights Templar.
