History
The Domo was the ship in which the ten Eternals created by Arishem came to Earth 7,000 years ago. After they ventured into the world, the Domo was left in Babylon (modern day Iraq) where over time it got buried underground. For centuries it served as the home of Makkari who used her super speed to get in and out without any humans noticing.
After they were forced to kill Tiamut, Druig, Makkari, and Thena used the Domo to leave Earth in search of the others of their kind. They were eventually found by Eros, the brother of Thanos.[1]
