Eterna, an all-powerful supercomputer governing Earth's systems and space territories, enforces a system-wide shutdown targeting unregistered spacecraft lacking independent propulsion. This action strands countless individuals across the solar system, leaving only unauthorized vessels like the Iron Goblin operational. Designed by a prominent scientist, Eterna's shutdown directly impacts the protagonists when the scientist's daughter, Mayfa, is rescued by the Iron Goblin's crew and becomes involved. The supercomputer exerts control over Earth's essential infrastructure and power distribution. In the final episode, an alien species sharing the name Eterna emerges, introducing a new layer to the conflict surrounding the supercomputer. The crew's mission shifts to reaching Earth, confronting the supercomputer Eterna, and overcoming its control to restore operations and save humanity from its imposed restrictions.
