SPOILERS FOR A NEW GENERATION!

Years ago, before the time of Sunny Starscout and her friends, there was Twilight Sparkle and the Mane Six. They were the Guardians of Harmony, defending Equestria from any threat that came! However, there was a story that one fateful day, Rarity went demonic and insane, turning against her friends and making friendship and Harmony be replaced by paranoia and mistrust and causing the three pony kinds to be separated.

This...is not that story.
