Queen Chrysalis is the ruler of Equestria. She has a lover, Shining Armour. 1,000 years ago princess Cadence ruled along side Chrysalis. But when Shining Armour chose Chrysalis over Cadence she went on a ramp page. Chrysalis was forced to send her to exile Island. Now Chrysalis has a loyal student Gilda the griffon, the element of Honesty. Gilda's friends are Octavia, the element of Generosity. Soarin, the element of Kindness. Vinyl, the element of Laughter. Spitfire the element of Loyalty. Sunset Shimmer the element of Magic. On Changeling Day Cadence some how escaped and is now back to take over Equestria and make Shining love her.
A/N: I might have been the only one thinking this but, if Chrysalis is a Queen shouldn't she rule Equestria? This is a part of the Queen-verse
