Everypony turned to see the one the voice belonged to and they all saw a being they couldn't recognize except for Twilight. It was of a species she had seen quite a few times and many of the race. It was a human. But it wasn't just any human, she recognized it for her own reflection from across the mirror, however the one present was without a doubt some form of demon.
"Midnight Sparkle. What are you doing here? And how are you even here?!"
Cadence looked to her sister-in-law, she obviously knew who this was. "You know her?"
"No, but Sunset Shimmer told me about her. The me from the alternate world was consumed by magic fueled by the hatred of her companions and her personal fear and became her. Sunset used the magic of the elements of harmony that was in the other world to defeat her and save the other Twilight."
Midnight just looked down on Twilight and gave a short laugh before answering, "I may have been defeated but my magical energy remained. However I couldn't create a physical body so I just absorbed all the residual magic left in that school, as well as some magic that belonged to three girls, but they couldn't use it and it didn't affect them so no harm to them." Twilight knew those three girls must have been the sirens but she didn't say anything, she just keep listening. "However, even with all that magic I still couldn't create a physical body for me. And then the portal to equestrian that had been closed reopened when you went through it. And so I traveled to this land and just by coming through the portal my magic increased and I was able to create a physical body and that body connected to you princess Twilight so my magic increased even more."
Rainbow Dash flew decided she had herd enough talk so she flew up to her and told her, "So? We have four alicorns on our side and the power of the elements of harmony so you can't beat us. No matter what you're trying to do!"
Midnight just grabbed Rainbow with her magic and tossed her aside. "It's rude to interrupt someone when they're talking. And before you say anything else you Wonderbolt wanna be, I know all that perfectly. When I created my physical body it based itself on your friend, so everything she knows I know. Besides, you didn't think I came here unprepared did you?" After that she pulled out a gold staff with three upside down crystal triangles making a larger crystal triangle.
"You see, with my magic, I was able to find this. This staff not only does it boost my magic but it increases my knowledge just by being in the presence of it. For example just by being in this room I'm obtaining all the knowledge you ponies have, this staff is making copies of everything you know in my brain and at the same time it's like I'm reading and memorizing to perfection all of the books in Canterlot. Soon all the knowledge in Equestria will be mine and I will rule this land."
"Do you think we shall let you do as you please you fiendish being." Luna stepped to the front of the group, "You can not win no matter the artifacts you hold, you may as well stop all this and give up."
Midnight just smirked and answered, "If you can really stop me, then try."
Luna attacked using her magic but Midnight jus put up a shield and deflected the shot.
The princess of the night stood in awe as she saw her spell had been deflected. "H-how...? No one should be able to deflect alicorn magic without effort, yet you treated it like it was child's play."
"I told you, you can't beat me."
Celestia knew this enemy was strong but she could probably be overpowered if they all stood together, how ever there was more she wasn't telling them. "Enough of your taunting. How are you behind the attacks on the Crystal Empire and Cloudsdale?"
Midnight stared the ruler in the eye and smiled. "A simple spell really. I needed someone to keep you busy while I absorbed the knowledge of the land. So I used an ancient spell created by the necromancer Demigra to create stronger copies of the most dangerous threats this land has ever known." And with a wave of her staff appeared five images. They saw indeed the greatest threats to Equestria; Nightmare Moon, Discord, Queen Crysalis, King Sombra and Tirek. They all some how looked crueler and their bodies had all changed to a deep purple color as well as having their eyes red with dark purple stripes under them.
They saw Nightmare Moon reconstructing the castle of the two sisters and use her magic to bring the night and as they looked out the window it had indeed become night, as for the evil Discord he was in Cloudsdale so that kind of proofed Rainbow Dash right, Crysalis had made the Crystal Empire hers, meanwhile Sombra was in the crystal mountains in the Frozen North and he had created a dark crystal castle and Tirek was in the Firelands just past the Fire Swamps.
"You're a monster"
"I'm no monster, I'm your sister"
Starlight was terrified at the situation. Had the princess, her new mentor, really faced all of this. She now fully understood why her friendship was so important to Equestria. "Why are you doing this?"
"Because knowledge is power. And soon I will be the most powerful being EVER! In any case I already got what I wanted from here. And good luck in stopping me. But face it; the power of the four alicorns is not enough to stop me and you don't know how to summon the power of the elements anymore so you might as well give up and accept the fact that I will rule Equestria." With that she teleported and left.
Everypony just stood in awe until Cadence broke the silence, "How are we ever going to beat such a powerful foe?"
