The year 1791. A famous Venetian doctor, illegitimate son of the German opera singer Dorothea Nacht and the Spanish aristocrat Duke de Valsombra, after the death of his ailing mother, goes to distant Cantabria to personally convey the sad news to his father, and to claim his birth-rights. He comes to the masquerade ball, given by the prince on the occasion of his seventieth birthday. In the garden, he meets by chance his brother C sar, the Marquis de Viciosa and officially the only son of the prince. Rejected by his father, August Nacht vows revenge on him and his entire family. He goes to the old forest where Iduna lives, a woman gifted with great intelligence and a rare gift of telepathy. She once saved his and his mother's life. Just as August wants to take revenge on the prince for the harm he suffered so does she...From that day, Augustus' odyssey begins in a strange and mysterious land of forests, streams and ghosts, in which Celtic traditions and beliefs are still alive, in a world to which he himself belongs, but which he is afraid of and does not fully understand.
