[b]Origin Info/Details:[/b][quote=Hesiod’s Theogony]From the Heliconian Muses let us begin to sing, who hold the great and holy mount of Helicon, and dance on soft feet about the deep-blue spring and the altar of the almighty son of Cronos, and, when they have washed their tender bodies in Permessus or in the Horse's Spring or Olmeius, make their fair, lovely dances upon highest Helicon and move with vigorous feet.[/quote]
The Athanatoi arrived on Earth long before humanity had developed any form of written language.  These beings, along with their sister race, the Hemithanatoi (ἡμιθάνατοι), took on human forms in order to better “fit in” with the local fauna.  Therefore, [url=http://en.wikipedia.org/wiki/Xenophanes]Xenophanes[/url], a Greek critic of the anthropomorphic depictions of the gods, was correct in saying that if dogs and horses could draw images of the gods, the gods would look like dogs and horses because the gods were shape shifters.  However, both the Athanatoi and the Hemithanatoi kept their residences on separate worlds (akin to how Marvel handled the several realms of Norse Mythology), even though they had the technology to transverse between worlds.  

Once the Athanatoi began to be worshipped as gods by the ancient population of Earth, they began to build devices that could convert the sacrifices and worshipping of their followers into power that could empower and sustain the Athanatoi.  This power was [i]Ambrosia[/i], the Nectar of the Gods.    During this period of time, the Athanatoi would occasionally descend to the earth and mingle with its people, sometimes even producing offspring with the mortals.  These hybrids are now known as the heroes of Greek Mythology.

However, after the collapse of the Bronze Age civilizations, the Greek Athanatoi ceased their direct interactions with the mortals of earth.  Besides a few exceptions, the Greek Athanatoi never again placed a foot down on earth.  In spite of their absence, the Greek Athanatoi still received worship long into the Hellenistic Era of the successor states of Alexander and the rise of the Roman Empire.

However, once Christianity became the official religion of the Roman Empire and spread across Europe in the Medieval Ages, and once Islam flew through Northern Africa, the heads of the Athanatoi pantheons called together a meeting, deciding that, once these new religions had secured their positions and extinguished their worship among the mortals, the Athanatoi were to refrain from affecting affairs on Earth.  However, if something from the past has reared its ugly head back in the future, the Athanatoi have full permission to intervene, as it was because of them that humanity would be in danger.

As time went, the Greek and Egyptian Athanatoi withdrew from earthly affairs, and even the Norse Hemithanatoi did too once Christianity reached and assimilated the North.  As the energy gained from their worshippers dwindled year after year, the Athanatoi adjusted their devices, allowing them to produce their subsidence without mortal followers.  While this allowed the Athanatoi to live on, the devices were less efficient without worshippers.
