Going back several minutes in time...
When Meryl had launched a powerful beam that could equal the strongest attacks of Mid-Tiers, the ship of Garenjazz was greatly damaged. And the momentary attack revealed the real form of the ship, and everyone was able to enter the dream world.
From the outside, everyone saw a vast mist. But as Alean and the rest moved into the mist, the entire landscape changed, and even the gigantic Hypersphere was no more. It was as if they had stepped into a different planet, and a world of strange possibilities stood before them.
Cliff and the Basilisk Squadron, the Gryphon Squadron, Meryl and the Twelve Disciples, Lynd, Seeker, Meryl's parents, and several other soldiers who were trained bravely charged into the mist and entered a world beyond the three dimensions.
