France 1565. It’s been ten years since the physician and astrologer Nostradamus published “The Prophecies.” Since then, his reputation has not stopped growing. The master receives many letters asking for his help but his advanced age and fragile health mean he can no longer respond to these requests. However, he is not prepared to forego the generous rewards offered to him. So a surprising idea crosses his mind: send his three young students on his behalf. Arthus Trivium, Angélique Obscura, and Angulus Dante travel across the country to unravel mysteries that neither religion nor science can solve.
