"1208, a Knight Templar brings a mysterious manuscript back from the Crusades and a dreadful plot is hatched. In agreeing to hand on this document to a friend of his father, Simon de Lancrois thought he was simply fulfilling the last wish of a dying man. Now he finds himself on the road to Campostella pursued by Pope Innocent III. Superstition reigns all around, with both angels and demons poised to take part in the struggle."
