This device was built by N.O.V.A. forces based on a stolen ancient Judger artifact. It was brought to San Francisco (Earth) in the hope of using it to make the planet inhabitable once more so humanity could leave the Orbitals and break free from the control of The Dominion and clam independence. According to Yelena, it must've broadcast a signal, as the Volterites became aware of it and wished to seize it so that they could turn it into a weapon of mass destruction.
Yelena approached Kal Wardin with this dilemma and said that unless the powerful device was secured, the Judgers would destroy both humanity and Volterites. Once Kal secured it,he was confronted by Prometheus. He explains the faults of humanities behavior and actions before taking possession of the artifact on the behalf of The Judgers, and what he did with it next is unknown - most likely it was transported to a safe location of Judger origin.
After this, Prometheus sent Kal to retrieve two more unidentified Judger artifacts to atone for humanities actions of stealing the first artifact - one that was on Therrius, and another that was on Boreas. now that the Volterites hadbeen set on the trail of other Judger technology capable of unbalancing the galaxy.
- The theft of the Judger artifact component used for this device sets in motion the events of N.O.V.A. 3
