It's a story everyone knows. Nightmare Moon wins, the Princess disappears (sun preserve her), and eternal night descends on Equestria. Darkness begets terror, and terror smothers friendship. In other words, things fall apart exactly as expected. And then ponies get on with their lives. Funny how that works.

Well, in her defense, monster hunting seemed like a nice gig at the time.
