The setting of the story is rich and deeply fleshed out. It follows the large, peaceful, anarchic society of the beast-men, a generic term for dozens of non-human races, who peacefully coexisted with each other for centuries until they ran in to humans. The beast-men eagerly invited the human's to join them in their paradise, but the humans who mistook them for savage monsters attacked, sparking a war.
An untold amount of time later, humanity is on the brink of extinction having been slaughtered in a series of wars and hunts by the beast-men, who realize that to continue to live peacefully, cannot allow humans to exist.
It is in the morally grey world that the Golem must smuggle Somali who will be killed if her identity is discovered, as the two desperately search for any remaining humans while under a strict time limit.
