Dark Moon (Divine War) (Volume 3)

Earth: bleak, barren, ravaged by the monsters they call the Horde. As the Emperor and the Imperial fleet arrive on their homeland, fulfilling Moses' mandate at last, they find a planet whose population can survive only underground. As the Archeonean forces speed towards Earth, anxious to capture the tyrant Emperor, it's up to Maicee to broker a deal. Fighting together the Emperor and the Archeoneans may just defeat the Horde. Apart, they will surely fail, and rip Earth apart in a civil war. Reunited with his loved ones, Maicee must do what is right, and the Emperor must make the ultimate sacrifice.
