"Unknown mercenaries are frequently hired as contractors for their exceptional skills in combat. To avoid friendly fire and security issues, REYAB Corporation distributes an altered version of its uniform and refers to its hired hands as Enigmia, who fight on behalf of the conglomerate with ambiguous intentions. Some Enigmia eventually join REYAB as fully-fledged members loyal to the organization and its vision for humanity, shedding their purple mantles and having their Unknown markings removed. Others allow their contracts to elapse, seeking to make their way through the world as soldiers of fortune for the highest bidder."
