Armageddon... The ultimate sin of humanity, perpetrated upon itself, which cast the shroud of death across the world centuries ago. And out of that lasting darkness, they emerged... From the legends of ancient times, they have been called forth into the world anew... Vampires.

Two races, Terran and Methuselah, human and vampire, are locked in a struggle for existence, trembling on the brink of war. Some seek the path to a peaceful coexistence, while others pursue a dangerous shift in the balance of power… And the world's enemy, Contra Mundi, is starting to move. Cooperation and goodwill between the two races may be their only chance for survival.

Abel Nightroad, a touring priest for the Vatican, walks calmly where others fear to tread. A member of the formidable AX, tasked with the protection of the fragile equilibrium. Neither human nor vampire, with an awkward yet optimistic nature, this Father is a force wholly his own. When the greater threat emerges, the enemy of my enemy is my friend… And Abel Nightroad seeks a safe path for all.
