Arnaud Calvez was born in Dinan in Brittany, the son of a spice merchant. But he longed for more than a quiet life in his father's footsteps: he wanted to see the Holy Land. So, at the age of sixteen, he joins the Christian order of the Knights Templar and follows their call to defend Jerusalem in 1185. In this exciting journey through the High Middle Ages, he not only finds a new faith, but also love and a bowl that would change the fate of mankind forever.
