Years past since the White Fang took drastic measures during their peaceful protest, and in those years they became more agressive. A secret organization called the Omega Syndicate was created to stop this agression but failed to do so early on in the history, so they created their own military called Hell Raisers, but that wasn't enough. The White Fang grew and created many strong holds in all 4 kingdoms and one of them fell into their hands.
Atlas was the Kingdom that fell, because of its small land mass, it was easily taken, Omega Syndicate sent its military to help and fend off the White Fang and failed, they use this failure to create a secret project called Project Angel , this was concist of war orphans and volunteers that wanted to take down the White Fang.
Many Volunteers and war orphans went through the tough training, but the worst was the agumentations they went through. The Augmentations increase the ability that each recruit has, if they are specialized in speed, it will increase where they will be in a different location under a minute.
The Agumentations was deadly, about over 2 million went through the agumentations, about half of that died through the agumentations, and half of the million were the war orphans.
The 1 million now Angels were suited up with high tech armor, some were bulky for the juggernaughts, some were less armored for the scouts and sniper, while others were equally balance for the balance types.
Omega Syndicate was known, but no one knows the full story, and no one knows who or what the Angels are and their intentions, not all becomes one and not all survives.
