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