Pawns forced to break a stalemated war, many humans became unwilling hosts to the alien race known only as "Sukkers"; a select few received genetic alterations from the "Ancients" and became super-human with incredible abilities to hold back the Drone armies. Millennia have passed, yet the War still rages. Alluvia did not start it, but the Descendants of the Ancients must finish it somehow.
