Twilight Sparkle sat alone in her room, writing anxiously with quill and paper. Her new desk was located right in front of a window,where moonlight shined through lovely luminescent curtains. Twilight had asked Princess Celestia not to make her room too big, but big enough to hold all of her books. It had only been two weeks since her princess coronation and her departure from Ponyville, and she missed her friends greatly.
She jotted one last period on her paper and sighed with relief. Applejack's letter was done. She was about to order Spike to deliver it with his dragon powers, but she remembered he was gone for etiquette classes. Many residents in the castle had complained Spike still lacked the proper qualifications to work in the kingdom, so Princess Celestia had decided a couple weeks in camp would serve as sufficient training.
Twilight yawned, and pulled out a fresh sheet of paper, Pinkie Pie would be anticipating a letter soon. But then, there was a knock on the door. Actually pleased to have a distraction for once, she eagerly sang "Come in!"
Princess Celestia peeked her head through the door. "Hello, Twilight. I'm sorry to interrupt, I just came to remind you the Summer Sun Celebration is next week, and you'll be expected to speak."
Twilight's eyes grew with worry. "What? Next week? I haven't even prepared a speech or-"
Celestia smiled comfortingly "I know you'll do just fine, Twilight. You're doing an amazing job."
Twilight blushed, looking up at her old mentor. "Thank you, Princess Celestia."
Celestia nodded. Twilight turned back to her desk "But I've still got a lot of work to do!" she said, levitating her books and papers, looking through them.
"Don't work yourself too hard. Oh, and your new help will be here tomorrow. She'll assist you until Spike returns."
Twilight nodded, only half listening. Celestia pulled out the door smiling, closing it behind her. Suddenly, as soon as she closed the door it felt as though the weight of a house were on her back, and she fell to her knees. Quickly, she used her magic to try and restrengthen herself.
"Not so young, are we?" Princess Luna laughed, emerging from the shadows.
"Luna!" Celestia frowned, still struggling. "You aren't so young yourself..."
"Oh, but I'm a lot younger than you big sister," Luna lifted her sisters chin with her hoof so her eyes met hers "and 1000 years locked away inside the moon keeps one surprisingly.. Fresh."
Celestia tried to growl in defiance, but her magic faltered. Soon, crows feet formed in her eyes, her hair no longer flowed shimmerously, and her soft white fur turned to an elderly pale. She collapsed to the floor, her true form revealed.
Luna laughed menacingly. "The true princess Celestia! If only her subjects could see her now!" she lifted Celestia's chin again "You don't have much longer, sister, and soon.." she smiled, darkness filling the hall shaking Celestia to her core. "The empire will be mine!"
