Era beginning/end
INTELLIGENT LIFE BEGINS TO FORM.
One of the earliest extraterrestrial races known to exist were known simply as the Elder Things. Their planet is completely unknown, but it is known that they began universal space travel many years before the others as they had lost their planet to a mysterious plague brought on by their war with a kaiju.
The Greys, having come from a red planet with a lush, Mediterranean-esque environment. Greys are a humanoid alien race with four-digit hands.
Another were the Xothians, a race from the water planet of Azathoth. Their physical
appearance resembles that of cephalopods, but there is no relation genetically. The similarities are simply a byproduct of convergent evolution. There is archaeological evidence that the Elder Things visited Azathoth and took the native shoggoth fauna with them.
Another race was the Angels, who lived upon a planet of glass and marble called Eden. They housed their frail organic bodies in elegantly crafted mechanical ones made of porcelain and gold that resembled statues.
Other extraterrestrial races came to be, such as the Martians, Neptunians, Venusians, Jovians and more.
