Shadows

"The one, The only, Princess Celestia!!!" The announcer shouted. Except nothing happened when the curtains parted.
There was nopony there. Everypony was silent for a few moments before they started panicking.

Then there was a Massive peal of thunder, [and for a second Dash thought she had went out of phase in shock] and suddenly there was a dark pony there. It was dark and evil, covered in armor that Dash could just tell was magical.
It spoke.

"Oh my beloved subjects, it's been so long since I've seen your precious sun-loving faces." She drawled in a manner that told Dash that the mare thought herself far superior to everypony.

"Where is Princess Celestia?" AppleJack yelled out. Was she stupid? This being could probably send them all into oblivion.

She laughed and said.

"Why? Am I not Royal enough for you? Do you even know who I am?" Dash didn't but she knew that she was trouble. Pinkie began babbling but Twilight shoved a pastry in her mouth.

"Does my crown no longer count? -" The mare continued but was cut off by Twilight.

"No It doesn't Nightmare Moon! Princess Celestia banished you for a reason!" Dash looked at twilight like she had just said that pink was not the mares color. Everypony else just gasped.

"You know why I'm here, do you?" Nightmare Moon queried.

"To cause... " Twilight started, but faltered.

"Remember this day, ponies for it is your last!" Nightmare Moon picked up where Twilight let off.

"There will never be another day! This night is eternal!!" And then in a very dramatic cloud of blue mist Nightmare Moon phased out.

Regaining her bearings again, she flew after twilight and landed in front of her.

"When did you get there?" She demanded.

"What do you know about this nightmare moon character? Tell me now!" She became aware that she was wrapped in magic and unable to move. Twilight's horn was aglow. She was helpless at the hands of her captor.

"All I know is that we have to use somethings called the elements of harmony to defeat her." Twilight carried her with her magic back to her library and set her down on the floor.

"What was that for?" Dash yelled thoroughly angry at the situation.

"You've been attacked by her magic." Twilight explained.

"What? I don't know what you are talking about"

"Well you were!" Dash was suddenly made aware that their were other ponies in the room.

"We heard your explanation darling and would love to help." Rarity said.

"Well you can't start helping me if I can't figure out where the elements are!"

Suddenly Pinkie pie had a book out and read off,

"There are 6 elements of harmony, though only 5 have been identified. There is kindness, laughter, generosity, honesty, and loyalty." Twilight grabbed the book and read it over. She continued.

"The last known location of the elements of harmony was in the ancient castle of the royal pony sisters. It is located in the EverFree forest." And with that, the journey to the castle began
