The Earthling Sergey Zmeev is an Observatory—Guardian of the Intergalactic Law established by the ancient Forebears. His duty is to protect rational life. But instead of silence on a space station, he ends up in a cage on an arena planet, where life is the stake and death is entertainment for the crowd. He is forced to fight. But he has another task now… He must go through three circles of hell—defeat his own demons. Around him are enemies, false allies, and secrets hidden behind a thousand-year veil. And at the center of it all is the Archive of the Forebears—an ancient repository not of knowledge, but of the conscience of an entire civilization. And only he who can truly respect life has the right to wake it up. “And one man in the field is a warrior” is a cosmic dystopia about the choice between power and humanity, where true strength lies not in a sword, but in refusing to use it.
