Five hundred years ago, Armageddon nearly destroyed Earth. Out of a vanquished world the Catholic Church arose from the ashes, only to be wrought with deception. But an enemy far worse than corruption lingered in the darkness. Vampires, ravenous creatures that only existed in nightmares, now walk among humans . . . waiting to feed on the blood of humanity. To ensure the peaceful coexistence of the dead and undead, exceptionally talented individuals have been secretly integrated to form the ultra-tactical team, the AX. This team works to protect human interests and to punish those who threaten the Vatican. Ironically, their most powerful agent is not human. It's up to the AX to save humanity in order to resurrect the forgotten days of peace.
