Humanity awoke in the citadel, a massive silvery megacity, one day without anything but the skin on their back. This takes place roughly four hundred years later. Where maga (mages) and militarex (warriors) exist due to the discovery of the red and blue pill artifacts.(do be aware that the language is a bastardized latin. So there may be terms your not familiar with, will address them in the comments if possible)
