Dawn of Civilization
A group of Nibirites who were outcast from their own society in the harsh desert realm of Nibiru, they were offered a place of refuge by a Traveller to their realm called Nanna-Sin. He offered them a new home and the opportunity to flourish in his own realm. This offer was quickly accepted, and the Moon god Nanna-Sin created a bridge to transport hundreds of Nibirites to his city of Ur.
While grateful for their new home, it was readily apparent that their “benefactor” sought to use of in his games of conquest. He placed them in work camps to produce magical equipment for his armies, and harnessed their shapeshifting and magical abilities for his raids.
Unhappy with his lot in life, the Nibirite known as One-Eye led most of his exile brethren in a mass exodus through time to a place called Rome. There they used their shapeshifting abilities to blend into their society.
