Grimbert, Margrave of Turin, nicknamed the Spider by many ill-wishers, has been prone to political intrigue since childhood, imagining himself a talented manipulator who always achieves his goal. At some point, he made a fatal mistake, becoming the target of the conspiracy himself, and this moment crossed out everything that he had. There is no more title, honor, or respect to which he is accustomed. There is only battered knightly armor, a couple of outdated guns and a little craft of raubritter. A robber, mercenary and adventurer without coat of arms and honor. But in a scorched radioactive world already bursting at the seams, riven by feudal and religious strife, this is already something. Who knows, maybe Spider will be able to accumulate enough poison to take revenge on his offenders... Combat dystopia, furs with robot knights and glorious heroes who are not averse to seizing power or going the hard way to correct perfect mistakes. "Fidem" is the third book of the trilogy "Raubritter."
