An Old Whooves Tale.

Derpy once again moved the fog that surrounded the castle with ease to make way for Princess Luna. After a few minutes going through the fog they finally reached the entrance of the Castle. Some additions were made since the last time Derpy had seen it.

“So this is where this beast resides is it?”

“Yes your highness, please allow me to lead the way,” Derpy said as she entered the castle. Princess Luna looked around at the tall stained glass and tapestries with her horn as only source of light. The window that was broken from before had now been repaired, but unbeknownst to Luna. Derpy finally led her into the throne room and Princess Luna was a bit shocked at the size and elaborate detail of the hall.

“Um Ms. Hooves, where is this creature again and what does it look like?”

“Oh just like an innocent little filly,” said a voice from out of nowhere. Luna spun around and shined her light to revel the same dark green pony from before.

“Revel your identity!”

“Our name is Sugar Princess, Sugar Song.” Luna let out a little gasp and forced her horn to glow ready to blast the pony if she made any sudden movements.

“I know you monster, you’ve possessed this filly. I will not be tricked by your disguise, now revel your true self to me!”

The Filly simply laughed and strolled around the throne room.

“Oh in due time Luna, in due time. Might I say I love your ferocity, it makes you such a confident and powerful leader.”

“Silence creature!” Luna commanded. “Now tell me what, why have you built this castle? Do you wish to conquer Equestria?” The filly giggled again and danced around Luna.

“Oh Princess Luna, we’ve built this castle just for you.” Luna slightly let her guard down in surprise.

“Explain yourself!” She commanded.

“Oh dear Luna, we are not ignorant to your work and your desires. We understand the struggles you go through to grace us with the night and darkness. The ponies around here don’t give it a second thought. Yet we understand, that’s why we decided to build you a fresh start for when you become ruler of Equestria.” Luna dug her hooves into stone and prepared herself to fire.

“What does thou mean, ruler of Equestria? I already am a ruler of Equestria.” Luna’s comment only caused a wave of laughter to erupt from the filly up into the darkness.

“Oh Luna we all know you are not actually in control of any part of Equestria. You share a throne with your own sister who has been slowly over the years been taking it away from you.”

“Liar!” Luna yelled out firing a magical blast that stopped the green pony in her tracks.

“Are we? Or do we speak the truth you try to hide?”

“Lies!” she growled back, horn glowing again.

“Well consider this then Princess. Do you ever make visits to the different villages and towns in Equestria? No that is your sister, because eveypony is asleep during the night. Tell me what official decrees have you issued since the start of your reign.” Sugar paused for an answer, but Luna simply looked hard at her without a response. “Exactly. How often do the ponies go out and enjoy the nighttime that you slave over every detail of? None.” Luna had now raised her horn and was listening intently on the pony’s words.

“See your highness? The proof is there. Your sister has been slowly taking your grasp away from the crown by tricking the citizens of Equestria into loving the daylight rather than the moonlight. Yet we offer you power, we offer you an opportunity to make a change. You can over power your sister and keep it night forever."

"Then your citizens will learn to love you and embrace the moon.” Luna stayed quite and walked away from Sugar. Princess Luna’s thoughts were all twisted and confusing now.

She wasn’t sure how to make sense of the creature’s words. They all had the probability to be true, and Luna even had some of the same suspicions before, but she had never found any reason that her sister would want to do such a thing. Her thoughts were going a mile a minute, but then she realized she had not heard from Derpy the whole time they were in there. Luna turned around and shined her light at Derpy who had a blank expression.

“Ms. Hooves?” Luna asked.

“Yes Princess?”

“I thought you said you were afraid of the dark.” Derpy’s eyes widen for a moment and then her face simply curled into a smile.

“Very perceptive Princess.” Luna realized what had happened now; she was drawn into a trap! Luna flew toward the hallway and escape, but an army of ponies descended from the darkness above and force her down.

The TARDIS slowly faded into the front of the castle and the Doctor rushed out as soon as it was tangible. He hoped that he hadn’t arrived too late. With his sonic screwdriver in his mouth he rushed inside the castle and made his way to the throne room. When he arrived the Doctor saw Sugar Song standing above Princess Luna with a smile.

“DOCTOR!” Luna cried out. Every possessed ponies attention snap to the doorway and the Doctor froze. Sugar smiled and motioned for Derpy to catch him. The Doctor was stunned to see Derpy possessed and ran back toward the exit.

“PRINCESS I’LL BE BACK I PROMISE!” the Doctor called out.

“PLEASE HELP DOCTOR!” Luna called out still restrained by the possessed ponies. Sugar Song bent over so she was eye level with Luna.

“Ah Princess Luna, you could probably escape if you really wanted too, but you wouldn’t dare hurt your precious subjects would you?” Luna struggled again, but she was unable to get free.

“I thought not, don’t worry we’ll fix that.”
