In the Beginning.
Jor-El and Lara escape the destruction of their home planet Krypton, crash landing on an Earth that is stuck at a medieval level of technology and culture. A band of mounted archers ride out from a nearby castle to attack them as Lara gives birth, but Jor-El obliterates the attackers with his heat vision just as their son, Kal-El, is born. Meanwhile, in the Kingdom of Storms, a peasant named Constantine has a vision of demons who will conquer the world, while King Jefferson listens and orders the prophecy recorded.
