In the aftermath of, The Fall...units of Angels are dispatched to Earth to act as educators of man to the new world around them and their obligation to do well by one another. A rogue amongst these "Teachers" becomes Fallen, and in an effort to prove the weakness of humans and the necessity to rule over them, grants the vilest of the species with angelic abilities...creating the first of an immortal race known only as Forever.
These dark immortals begin to wreak havoc to the world. In order to show the strength and resilience of humans, heroic immortals are created and given the task to dispatch their polar opposites from the planet...starting an underground war that has raged on in parallel with the growth of known (and unknown) world history.
The most powerful and respected of the immortal heroes are part of a unit code named...THE 8!
