The daring and successful mercenary Caspar Frey serves the Duke of Angoulême, who rivals the king himself. The ambitious duke pays generously for the fulfillment of his whims, but sometimes he demands the almost impossible. To cope with the difficult work, Fry took into his team an exiled nobleman, a sorcerer without a diploma, a gnomesmith, an elf shooter and a voracious orc. They confront the cavalry of nomads, gangs of robbers and penetrate the capital of a hostile kingdom, becoming spies for the duke.
