If you are a wizard and want to achieve something in this life, find yourself a worthy master, because a wizard without a master is a wizard without a future. Thousands of years ago, the greatest of the magicians, Jassar Ansafarus, said that from now on, wizards are not allowed to rule and own everything, but only with advice and service can they support the thrones of their masters - mortal sovereigns. Jassar's word became the law of magic, and from that time to this day the law itself monitors its observance, mercilessly punishing violators. Tobius is twenty years old, and he spent three quarters of his life behind the impenetrable walls of the Riven Academy, comprehending the Art to the best of his ability. But the final exams are left behind, and the young wizard must choose a worthy master, in whose service he can show all his talents in order to survive himself and help others survive.
