- Mama Intro Pt. 2
The legends travel apart. The legends shall now see the same sky but shall stand on different grounds, shall stand on the same ground but shall see different skies. The day the grounds be kept a single file before one sky in two worlds that seem alike, the legends will greet each other. The day the red force is purified, the twelve forces will reunite into one perfect root, a new world shall open up.
