Genesis (Earth-2042)

"This place is incredible."

- Kelly-087

Genesis, also known as Nomos II, is a Forerunner world, the second planet in the Nomos system, artificially constructed by the Builders. It housed a secret Gateway into the Domain and regularly produced "seed worlds" under the direction of its monitor droid, 031 Exuberant Witness.
