Alexander Lemeshev, a fencing coach, by the will of fate thrown into the body of Jean d'Armagnac, the illegitimate son of Count Jean V d'Armagnac, one of the last feudal rulers by God's grace, meets Phoebus, Prince of Vian, and unexpectedly learns that the prince too came to the Middle Ages from the twenty-first century, after which he joins forces with him in confrontation with the powerful King of France Louis XI, nicknamed the World Spider. Phoebus defends his native Navarre, the bastard tries to return his ancestral lands and his rightful title. Another war is brewing in Europe, and the bastard will have to travel across Europe. Everything is as always: Saracen pirates, murderers, fights, intrigues and of course love adventures. First you need to gather allies in the fight against the Spider, then get the Pope to recognize your title, and then it comes to the siege of La Rochelle and the decisive battle with the King of France.
