Within the flowing eddy currents of creation, among billions of this universe's bright galaxies, there is one called by some the Milky Way. Spanning more than one-hundred-thousand light years, this galaxy contains more than two-hundred-billion star systems.The Kreel Empire has overwhelmed more than fifty of these star systems and ignited a bitter conflict with humanity. The smoldering inter-species tensions are a tinderbox that threatens to flare up and engulf even more star systems.As the Kreel and humanity engage in deadly skirmishes, neither is aware they are being observed by advanced species-together known as the Elders. Abiding peacefully within the galaxy and observing the actions of younger evolving species, they are debating what appropriate action they must take and which species-if either-warrants survival.The ongoing conflicts have also drawn the attention of another. An ancient evil from beyond the Milky Way has been drawn forth by the heady energy of interstellar war and death. Its malign influence is beginning to permeate the inter-species clash. Even as Guardian Force makes ready for combat on a scale never before witnessed by humanity, the balance of power is about to change forever. . . .
