The Origins of Vampires
In the beginning, when Earth was still a void, there were other places where life existed. The oldest of all of these places was called Aeternus Pacis, or 'Eternal Peace', because the original name has no translation in any language of this earth.
Aeternus Pacis was populated by a race unlike any since. In appearance they resembled humans, but in every other thing they far surpassed them. Their intellect was immeasurable, the speed of their limbs faster then the light itself, their sight stronger and sharper then human terms can define. Their bodies were impenetrable to anything but their own power, they had no need of sustenance or rest, and their lifespans were infinite.
This race experienced the same continuing cycle of war and tenuous peace that other nations have since made redundant. With such immense power at their disposal, however, their wars ended in a near-extinction of the species, and culminated in the eventual enforced peace that became their legacy.
The peace was never broken again. Three hundred thousand years passed before the damage done to Aeternus Pacis during the wars became too much for it to sustain. Their world began to slowly crumble away. Realizing the necessity, they began to search for a way of preserving their species.
Although their circumstances were dire, the people of Aeternus Pacis realized that they could not, in good conscience, place another species in peril to save their own. Their only option was to find a planet inhabited with life forms enough like them in appearance so that they could live among them undetected.
In a happy accident, the planet Earth was discovered. The people of Earth looked much like the people of Aeternus Pacis, but they were far more vulnerable, contracting disease and growing infirm. They moved and thought more slowly, their eyesight and intellect were weaker, and their lives had a time of ending.
The people of Aeternus Pacis also realized that they could not displace the Earth-Children with their own numbers, and thus they chose seven of their own to continue their race among the Earth-Children. These seven were called the Firstborn.
Compared with Earth-Children, the Firstborn were incredibly powerful. Their infinite lifespans and their very developed way of life soon gave rise to the idea that they were gods and were to be worshipped. The Firstborn discouraged these ideas, but the seed had already been planted.
The Firstborn quickly realized how dangerous it was to allow the Earth-Children to know their inhuman abilities, and they resolved to hide as best they could among the Earth-Children. Because the Firstborn did not age as the Earth-Children did, this required the Firstborn to move from one area to another about every five years, to keep their secret safe.
The Firstborn also discovered that they could not reproduce on Earth as they had on Aeternus Pacis. They were not, however, without recourse. It was also discovered that if a Firstborn happened to bite an Earth-Child and inject their venom, it would transform the Earth-Child into a slightly weaker version of the Firstborn.
As the years progressed, the Earth-Childrens' culture became more advanced; and with such advancement they also began their slow decline into moral decay. Some of the Firstborn began to tire of the perpetual state of hiding, the need for the façade of normality. They despaired for the human race, and without the human race, their own race would also become extinct. These Firstborn slowly began to fade from existence. Soon only one remained.
