What is known is that they have visited the
Earth at four different periods in the Earth's past, each time altering the course of history. The first Celestial Host came to Earth approximately one million years ago to perform
genetic tests and experimentation on Earth's highest lifeform, the nascent
human being. Testing the versatility of human genes, the First Host created two sub-species of humanity, the
Eternals and the
Deviants. Their sole legacy to the mainstream human race was the implantation of a dormant DNA complex which would one day permit benevolent
mutations.
