Set 20 years after Discord was defeated by Twilight and her friends, Discord has escaped his prison once more.  But this time, he's not just seeking to spread chaos, but also to exact revenge on the two ponies who ruined his plans before, Princess Celestia and Twilight Sparkle.

Seeing the signs of Discord's return Celestia sends the group on a quest to visit 6 magical bunkers built around Equestria.  At each of these bunkers they are to send a letter to her.  Revealing no more and simply telling them to "have faith" she sends them on their journey.

The group travels in search of the bunkers, each time sending a letter, and each time losing a member of their group to Discord.  Not once did they receive a reply from Celestia, but even with friends lost they continued, always keeping their faith in the princess, believing that by the end of their travels their losses will have meant something.

This is my first attempt at writing so any constructive criticisms and advice are greatly appreciated.
