Kirshtaria summoned panhuman history divine spirit Atlas, so it's the classic divine spirits Authority. If there was a tech to do that in the LB, he wouldn't need to summon panhuman Atlas. It's probably because in LB5's history, the entire planet already played by the rules of Zeus, so there was no need for texture pins, as there is no texture to be washed away since humans are fully controlled by the mecha gods.
The only question left is whether Atlas was a local divine spirit who got mixed with the alien ships and become part of the pantheon or something else.
