"The Warworld Saga, Part III." Everything has changed. After the heart-stopping events of Action Comics #1037, Superman and the surviving members of the Authority see a side of Warworld they never knew existed. In the lower catacombs, Superman finds another survivor of the lost Phaelosian race of Krypton, a scientist turned enslaved gladiator with much to teach Superman of his new home, including how to survive-and maybe, in time, how to escape. Meanwhile, Superman's quest to turn the hordes of Warworld against their masters begins.
