"Tarvit, welcome to Undervelt!" - everything he knows about himself and the place where he finds himself. Everyone who got here lost their memory. There's no way out of here. Fairy-tale creatures live here and strange things happen. Or maybe this is how it should be, because no one remembers how to do it correctly. Ross is called a detective from God, because it is he who is investigating the disappearance of the owner of a holding company specializing in high-precision technologies. But even in his worst fantasies, Ross did not imagine where the corporation’s secrets would lead.
