Humanity was slowly dying out, resources scarce and only the reliance on technology and/or old primitive ways were the only choice to continue.
Discovering old artefacts of yonder time, they found out the second being of life naming themselves as the Guardian species. With immense power in possibilities and their likeliness to humans, it was their only salvation as both kinds struggle their way to continue their desperate measure to keep the world alight.
However, this wasn't all. A secret governmental team of operatives scouted from all around the world was trying to find a cure for *The Happening*. An endangering disaster that wiped out most of the male species, whether human, animal or any type of sexual reproduction in the other kingdoms. Most females too, once you scavenge more into the deeper truth.
Equipped with weapons of bio-destruction made by both the species intelligence in weapons and nuclear scientists, they will mow down the terrorist groups, the hidden organizations, and any other party--that tries to stop their freedom and rights to a better tomorrow.
However as much as they fight, Hell just needs to grasp them to a closer end, with worse corruption.
