"So it was the Night Goddess's main plane. Those Avatars of Light were quite generous."
There was no mystery to solve; the answer was revealed soon enough. The Night Plane entered its leap-evolution state, shaking the Star Sea.
Luna, Goddess of the Energy Net, had prioritized the leap evolution of the Moon Goddess Plane. The Seven Deadly Sins said they could understand.
Selene, the Moon Goddess, was Athena's full sister, and they regarded her as family.
It was only natural for the Seven Virtues to divert resources to Selene.
This time, the Seven Virtues had given the slot for advancement to a high-level Origin Plane to Nyx, the Goddess of Night. The Seven Deadly Sins were unhappy about it, and mocked the Seven Virtues for being hypocritical and falsely righteous.
The Seven Deadly Sins couldn't accept such an important resource not being kept in their own hands, but instead being allocated to a non-family ally.
The Light Alliance tightened its defenses and stood ready. The Night Plane was all but impossible to take.
Still, the Seven Deadly Sins had to put on a show. They made as if they were attacking the Night Plane, tying up a large part of the Legion of Light there.
Meanwhile, the Seven Deadly Sins launched a major counterattack in the Primal Abyss and the Twelve Dark Domain Worlds, reclaiming lost territory and erasing the Light Alliance's gains over the years.
