Night of the Living Ponies

About a week after our conversation about Luna, I received word from the princess that Luna had gone missing. I started to wonder if she had become addicted to the dark energies of the crystal and escaped the temporary "prison" Celestia had put her in until the crystal was either contained or destroyed. I fear that if she has escaped, she would travel to the Crystal Empire in search for the crystal. If she finds it, there's no telling how much more powerful Nightmare Moon would become after absorbing pure evil energy in such large amounts. It could potentially be the end of Celestia, or even all of Equestria, as we know it. I began writing a letter to the Princess stating my opinion on the subject and what should be done. I suggested that we search all over the Crystal Empire for her, and destroy the crystal before she becomes too powerful. Should we be too late, we will do everything in our power to stop Nightmare Moon and destroy the crystal using the Elements of Harmony. After i received approval from the princess, I informed Applejack, Rainbow Dash, Pinkie Pie, Fluttershy, and Rarity of the situation and told them to pack for the trip to the Crystal Empire. It took three days to reach the empire, three days of wasted time. Who knows how close she is to the crystal. We hardly even took time to unpack our bags before we started searching. Luckily it didn't take long to find her. As i expected, she was traveling at night when no pony was around. We saw her going into the basement of the castle through a secret entrance that was unknown even to me or Celestia. By the time we reached her, it was too late, she had already found the crystal. I saw Nightmare Moon  just standing there. But when she turned around, i was horrified. Her face was horrifically scarred and mangled as if she had been dead or sent through a blender. Almost as if she had read my mind, she began to explain that she, Nightmare Moon, had technically died, however , Luna had not. She had went on about the new magic she had discovered and mastered while in Hell. She mentioned a spell that could raise the dead, I knew that wasn't good. As we tried to stop her, she cast a force field spell that was impenetrable by any and every means possible. She then cast a restraining spell on all six of us, and left us all for dead. It seems that she had forgotten I can use magic. I tried a teleportation spell and it didn't work. I began trying any and every spell that made sense in this situation, none of them worked. She knew more advanced magic than i thought. I then used a spell that sent a ball of magic into the air, which then exploded into the words,"Help us.". In hopes of catching the attention of Cadence, my brother, or Princess Celestia. We stayed there, rotting, for two weeks with no food, no water, no anything. We were all silent because we were either sleeping or too tired and discouraged to speak. But finally, on the 15th day, Cadence, my brother, and Princess Celestia arrived to save us. She said things are not well in Ponyville, that Nightmare Moon was governing it like she owned it. After we choked down a hefty meal and nearly drowned while drinking water, we rushed as fast as we could to Ponyville. Another horrifying sight. It was once again eternal darkness, as Nightmare Moon had what looked to be Lyra and Bon Bon fanning her as she sat on her throne that was forcibly taken from the shop owner. We rushed up to her as i yelled,"Stop!", in hopes of getting her attention, which it did. She looked up at us and said,"Silly ponies! You have no reason to be here let alone to try and stop me.". As I hid the fear and discouragement in my eyes, i said,"We WILL stop you Nightmare Moon! We've beaten you once before and we'll do it again!". After letting out a maniacal laugh, she said,"I've told you once before, I know magic more advanced than you could ever dream of knowing, and I will use it if I have to.". At that instant, I remembered the spell that raises the undead horde. She must not use that spell, we must stop her at all costs. After pondering the thought in my head, I said to Nightmare Moon,"I know that. And I will squeeze them out of you before I banish you to the moon for another thousand years after we beat you!", I knew i shouldn't have said that because the split second after I did, she yelled,"THEN YOU LEAVE ME NO CHOICE!!!", then she used the spell. At that moment i knew we were doomed. I saw the first zombie rise from the ground, then heard Spike practically have a heart attack and run back to the library. I then started to see hundreds, maybe thousands of zombies surrounding us, and at that moment I knew we were now in a living hell.
