Second half of the 9th century AD. The Empire of Magnus, which lasted less than a century and a half, once again disintegrated into the Four Kingdoms. The war for thrones between the numerous descendants of the emperor is slowly plunging Europe into a maelstrom of devastation. And of course, this chaos is very beneficial for some... What is the dark secret of the abandoned cathedral, built for some reason not in the county capital, but in a small border town? Will a few rogue robbers, temporarily hired into the royal service, be able to find the answer? And is this world worth saving, the only hope of which was the gang of Good Robin? Adventure fantasy.
