Equestria is changing.
Nothing ever lasts. Everypony knows this, but few understand it. And when something ends, what it was matters less than what it leads to.
When the pegasi of Equestria begin having difficulty flying, and earthquakes plague the land, Twilight Sparkle is tasked with finding out why. The answer will lead her down a difficult road, and Equestria may never be the same.
Equestria is changing, and those who call it home must struggle to change with it.
