My Little Pony: The Twilight Theory

The princess sisters have disappeared, and Equestria has fallen into chaos. Twilight and her friends set out to save Equestria, worried that the princesses will be disappointed when they return. Not long after becoming the Princess of Friendship, Twilight takes over as Equestria's regent. But most of Equestria's nobility and local officials don't recognize this newly crowned pony Princess of Friendship. In the northwest, unicorns obey the orders of the unicorn sisters. In the southwest, a pony claiming to be a descendant of Equestria's Princess Platinum incites ponies to rebel against the regent. In the northeast, a political movement centered in Manehattan forms to denounce the princess. In the southeast, a musician's rebellion breaks out. As Twilight suppresses the uprisings, she becomes increasingly extreme. One by one, her friends leave and begin trying to save Equestria and heal Twilight in their own ways. (This is a fanfic conceived as an alternate take on Twilight's theory in the Equestria at War chronicle. The pony images on the cover and in the illustrations mostly come from the Equestria at War mod.)
