In Becar, everyone knows that who you are in this life will determine what you are in your next life. The augurs can read your fate in your aura: hawk, heron, tortoise, jackal, human. Armed with that knowledge, you can change your destiny with the choices you make. But for the darkest individuals, you come back as a kehok, a monster, and you will always be a kehok for the rest of time. Unless you can win the Races.
