Nine Days of Hell: Celestia

Sometimes it's fun to play the princess-in-distress gimmick. Princess Celestia knows this all too well. Usually there is a happy ending according to plan. Really, she could escape at any moment, Twilight Sparkle and her friends have been so effective at rescuing princesses in the past, but this time, Celestia may have gone too far. She was having fun playing this game until she was thrown into Tartarus, and even coming to Tartarus wasn't too bad for her; after all, she was a goddess, but the bad part was that it didn't look like she was thrown here on a horse. Now, Celestia, who is basically a mortal body, and her most loyal students must travel through the barren mountains of Tartarus. The legendary prison for monsters is too unsettling and terrifying for their understanding of the world. Of course the entrance will appear automatically... This cool cover is by Cold in Gardez
