Exiled in Paradise
The ancient alien race who inhabited The Origin System until around 10,000 B.C. Created/mastered Dust , Built the Pandora Gates, and likely played a hand in the development of Humanity, as well as several other Alien Species. Little is known about them save for that they were prolific thinkers, builders, and adventurers who lived well beyond our current understanding of technology and science until they ran afoul of another , more powerful species, The Anunnaki
They seem to have resembled humans in many regards, having similar body plans (i.e., 2 arms, 2 legs, a torso, a head.), which many believe to have not been coincidental.
