History has been altered.
And now the continent of Migleina finds itself under the control of the East.
In order to unravel this mystery, Aldo and friends travel to the Garulea continent to investigate.
After countless trials and tribulations, they finally arrive at the Chapel of the Goddess of Time. And with it, find the final piece of the puzzle.
The Book of the Time Dream.
The Book, as it turns out, is actually a device that controls the main systems of the Xeno Domain, a laboratory created by KMS.
Back in the future, the Chapel of the Goddess of time is restored, and with it, Professor Madoka activates Project: Another Eden.
