When the Goddess died, the minds and souls in Unity spread out across the Alicorn race. From the ashes of her death, the Alicorns banded together and with assistance from Velvet Remedy created the Followers of the Apocalypse.
Radiant Star, a younger Alicorn and a newly initiated member of the Followers, experiences a terrifying magic that changes her body to appear similar to a certain Ministry Mare that was part of the Goddess. But the changes do not stop there. Star soon finds that she is harboring the barest emotions and feelings of Twilight Sparkle, and is desperate to understand why.
With her fellow Follower Violet Iris in tow, Star searches for the answers she needs. Soon she will find out that her transformation will affect the entire world.
