Throughout the course of human history, an incomprehensible event has constantly plagued the Zois mainland. For no reason, and without any warning, one city is wiped off the map never to be seen again. From each city that was wiped out however, one survivor would remain. The survivor would remain alive long enough to spread the message of what he saw. And even though no survivor lived more than seven days after the city's demise, the world came to know of the reason for the destruction. Ten figures, unknown to the outside world were responsible. History dubbed these individuals the Dark Ten.
