In the year 2075AKS (After King Solaris) Celestia and Luna left their planet to find out the meaning to life's great questions. They did not plan on being sucked through a wormhole and thrown into the future, but that's irreverent.
Now it's been three thousand years, although two thousand years ago a cult rose to power. 2112 years ago they made a new era AS (After Syrinx) Crushing all notion of freedom, creativity and individuality for their false God Syrinx. The Six High Priests run the world now, and they rule with an iron hoof. Let us look into the life of a stallion who's world was changed by a shocking discovery.
