In 1854, Caulborn agents stopped an interdimensional warlord named Sakave from conquering our universe. With protective extradimensional barriers in place, Sakave’s attempted conquest is now little more than a note in the Caulborn’s archives.
That is, until the recent catastrophe at Ashgate Penitentiary weakened those barriers and made Sakave a threat again. Things get worse when Commander Courageous gives Vincent Corinthos a dangerous piece of advice, which fractures those barriers even further.
Tapped for a black ops mission to repair the damage, Vincent finds himself under the command of a man who doesn’t trust him, and allied with an enemy he hasn’t seen in four hundred years. If they succeed, Earth and the Caulborn might pull through unscathed. If they fail, life as we know it ends.
