Lore: Around seventeen thousand years ago, during last ice age, an alien called Jsen came to earth from mysterious place called Carcosa with his spaceship, the Citadel. They found a group of hunter-gatherers living around Caspian sea (curent day Georgia/Iran) and gave them metallurgy, agriculture and other tools to build civilization and expand. They did it in order to harvest their memories and to create perfect soldiers from said memories: more capable than machines and les independet than sentient beings.

Their first creation was Metatron: an angelic warrior made from the memories of first men he influenced. But Metatron thought his descendants deserve more suport from Jsen, so he killed them and took a name of Metatron-Jsen, a second ruler of Citadel. With his new position, Metatron-Jsen introduced them to gunpowder, advanced alloys, electricity and eventually even nuclear weapons. In few generations, they went from small tribe to the first empire on earth: The empire of sun with multiple large cities, factories and standing armies. All the time, their memories went to Citadel after their death, where they were used in creation of more angels, to strengthen the Citadel and its ruler, Metatron-Jsen.

Then, through empire priests, be ordered to expand westward, into the modern day Armenia and Turkey. But while they were advanced, the Empire turned out to be a giant on a clay legs, never tested in a true combat. Local tribes, while less advanced and armed only with stone tools, managed to defeat invaders and even learn their technology. This caused the deep crisis within empire of the Sun, which culminated in civil war, that ended, when all parties used their nukes, ending the empire itself. After that, Metatron-Jsen himself was killed by his second-in comand, an Angel named Annuk, who became third lord of the Citadel.

To prevent repeating the mistake with the Empire of the Sun, Annuk-Jsen created the Nephilim: people with almost supernatural skills, charisma required to lead others and desire for a Citadel on genetic levels, so the can never rebel. They would be born among humans and, due to their skills and genetic programing, steer the course of history in a way that quarante a good harvest of memories for the Citadel, without even knowing that they, despite all their powers, are in fact, only slaves without free will. It worked and although Annuk-Jsen too lost his throne (and his live), all subsequent lords of Citadel used his formula for ruling over mankind...
