A war. Rainbow swallowed. Wars were something old. Something outdated. Something that ponies weren't supposed to worry about. The tribal wars? Nightmare Moon and her dark army? The Griffon Invasion? Those were for history books and for eggheads that obsessed over dates and the names of long-dead ponies. They were something to point to when you had to write a two-page essay on how Equestria had changed in the last thousand years. Wars weren't something that happened anymore.
