Because of Valtrude, the female Saint Knight, who was recited for his accomplishments, he will now be involved in territorial management. But there were piles of problems with the reconstruction of an abandoned city, in a dwarf that no longer produced iron, a shipping city that did not pay taxes, and villages plagued by monsters. The brave man who became the most powerful adventurer of the Brewers joins forces with his peers, challenging problems with sometimes magical, sometimes contemporary knowledge, and more or less cheaty financial power! Return to Earth, until that day a year later.
