A new trio of girls take the school by storm, inciting a music battle by tapping into the students darker desires. The magic, however, incites something different in Trixie and Maud; revenge and obsession.
Maud is home alone for a night. The perfect chance for Trixie's first sleep over at her totally-not-girlfriend's house. But, what if two of her sisters haven't actually left?
Equestria is under threat by a terrorist group that seeks to return things to the old days. To the days that the three tribes ruled the country, not the alicorn sisters Celestia and Luna.
