2034, the year the political group, Phyrhuss, took over the world and put in "The Provider" as the leader for the new, totalitarian dictatorship. Three years have passed and a resistance group, calling themselves the Wings of Liberty, are intending to put an end to Phyrhuss and create a world devoid of war.
Drejuni are the approximately 15,000 year old descendants of the now extinct Drecariums. They became extinct when the Drejuni actively caused genocide through cannibalism. Their potent stomach acids were a key component in how they devoured through the Drecarium. Their stomach acids were later developed into part of their hunting style, using their long tongues to strangle themselves and then excreting the stomach acids onto their prey .
(Basically, they choke em'selves with their tongues to vomit on bad guys and food).
