2039 AD December 22, Alien Humanoids appeared, Domineer's they were, an advanced race, in technology and physicality. They're arrival brought fear to humanity and how right they were.
Domineer's came with the intention of subjugating. Obviously Humanity fought back, modern military power held out, but were pushed back.
Variants; they were called, The Death seeker, most commonly seen, the accelerates and tankers. Guns, were not fast enough to land a hit on Accelerates, missiles not powerful enough to damage a tanker, and humanity were not careful enough for Death Seeker's, time to time referred as hunters.
Humanity scavenged the technology and integrated it into there current technology, but that took a century. 20 years too crasp the fundamental of there technology. Although due too the lack of resources it took 70 years to adapt it.
That was when they attacked back and pushed back the Domineer's on there back foot, Humanity recovered a century and two decades past and focused on offensive technology. And humanity decided they would not wait for them to come back so they went on the offensive. But in there haste the Domineer's targeted there military bases, food suppliers and once more humanity was on the cliff.
200 years of humanity keeping a stagnant clash, then being pushed back.
2480 AD Humanity was losing hope such as a man who was protecting his people that were in a underground base, as it was a secret supplier, to numerous base's. This man fought against a Domineer.
At the end of the battle the Domineer had holes in his body and half his face gone, and numerous scattered piece of earth protruding as spikes or broken walls, that was the first Meta, accounted for and was known as the start of the militaries strength.
Two decades past and Humanity found a way to give and teach theses abilities through MG serum's (Meta-Gene serum's) and a GI (Gene-Index) which contained information on the Meta-Ability.
Humanity fought harder and harder more and more, fiercer and fiercer.
But Domineer's grew stronger aswell, with Darker armour.
2678 AD; Humanity was being pushed back as Domineer's appeared wearing armour with beast like features, These were Beast Equipment, Humanity in turned found life on other planets, Beast were what they found. Integrating beast weaponry into there power and Humanity became more powerful than thought.
2700 AD; 300 years before the treaty between Humanity and Domineer's were established, in the 8th or eighth Planetary War, a monster, an abomination attacked both sides and War Hero's killed and learned it was a hybrid Domineer and Human. And after many more decades.
3000 AD the treaty was made.
and current time 3010 AD.
