An uneasy compromise, Tia!
"You have my word that I shall look into your proposed ideas when time presents itself for me." A mare nodded, bowed, and wordlessly began to leave her court, secretly jumping for joy inwardly at the thought of the lunar Princess going through her proposal for eliminating apples in a cost effective (But no less surely agonizing) way while reimbursing apple farmers across Equestria. As the mare exited through the doors, Luna's mind wasn't on the fact that she might finally have a solution to Equestria's infestation; instead, there was another, more pressing issue on her mind. Luna sighed, and rubbed her stomach gently; it growled in return, and she knew that she needed something to silence the insistent noise that was quickly getting out of hoof. Still, her court (And the ponies that came to it) came first, but since there were no ponies in the immediate vicinity, she dared to ask the question to a nearby adviser.
"...Is that all for the night court tonight? I see no others here."
"Yes, your highness, that is all for the night court. There are no more ponies waiting outside your doors to consult with you currently, and, truthfully, most ponies should be asleep by now, Princess Luna."
"Very well then, close the doors and lock them; the night court is closed for tonight! I have other business to attend to, so you may go home as well."
"As you see fit, princess." Her adviser bowed, and Luna nodded at him as he left; she took a few moments to watch as the ponies of her court began to leave her court, some trying to stifle tired yawns; they still needed to adjust to their new jobs at night, so she could hardly fault them for being a little sleepy. The growling sounded out again, and she knew that if she didn't act now, all would be lost, and Equestria would be put under even more peril if she did not get fed quickly.
Luna stood up from her seat, and promptly made a beeline to the kitchen; tonight, she had opened the night court without partaking in any food beforehoof, and that was a poorly thought out decision, as she found out earlier today. Meeting ponies on an empty stomach and trying to listen to their problems and proposals while also juggling her stomach was not one of the best decisions she ever made. She sped by servants and guards, nobles and commoners, disregarding all that was in her way between her and the kitchens; she wanted to please the ever hungry divine being that was her stomach, for fear of the unrelenting retribution she may suffer if she did not offer it sacrifices in the form of food.
After bursting into the kitchens, she saw her sister Celestia off to the side for the briefest of moments; she didn't take much heed of her, however. She was probably unable to sleep during her night and thought that a midnight snack would help her sleep. Running past a clearly startled Celestia, she dived over the table and danced around the gigantic, open kitchen area to reach her own personalized fridge, opening it up to the whole, wide world to witness the contents of her fridge, if they had been looking in.
That very fridge was full of nothing but moon pies; moon pies everywhere. The mere thought of having a treat named after her made her excited, but also a bit confused. For one thing, ponies named a dessert after her moon! On the other hoof, she didn't see anything that resembled a moon pie when she was banished to the moon, so she wondered how ponies even got the idea of calling these treats 'moon pies'. A mystery that would go unsolved, as she was too hungry to care about that now!
With impossibly swift movement, her hooves darted forward, grabbing a moon pie and removing the colorful wrapping with such practiced precision that it would have made Twilight Sparkle's organisation skills weep; she brought the delicious, formerly wrapped treat to her mouth, and with a delightful crunch, devoured half of the moon pie. Her mouth immediately went to work, crunching it down to smaller bits that she then swallowed, and after those were done? She bit onto the remains of the moon pie, and devoured them as well, setting an unofficial record of taking fourteen seconds to eat a double stacked moon pie. This process was repeated three times, and after the third, Luna sighed in relief as her stomach finally had its moon pie sacrifice for the day, and with that, the angry growling stopped, content to digest the moon pies. She turned around, ready to return to her duties, when she truly saw why Celestia was in the kitchen, or, at least, the remains of why.
Cakes. So many cakes, and what appeared to be former cakes as well, if the crumbs were anything to go by, which was a rather staggering amount of crumbs. She figured that Celestia was quiet only out of politeness, but it was really only to avoid drawing her gaze towards her and her...'Snack'. Luna could only stare as her sister giggled nervously, and tried to hide the half-eaten cake behind her, a chocolate cake, Luna guessed.
"...Hello, Lulu." Celestia's cheeks were smeared with cake, and it took all of Luna's willpower to not break down in laughter at the messy alicorn in front of her.
"Hello, Tia. May I ask you a question?" Celestia nodded slightly; while her poker face may be perfect in front of her little ponies, but in front of Luna, she could see the cracks in it, such as the subtle twitch of her wings, and the blink that accompanied her nod.
"C-Certainly! What would that question be, Lulu?" Unfortunately for Celestia, Luna was blunt with her question.
"How many cakes have you eaten?"
"About...Two?" Luna looked around Celestia, and concluded in five seconds that her sister was obviously lying.
"Liar, I see so many plates around you, there's no way it could have been only two cakes." Her sister's poker face broke, and she sighed before looking wistfully at the scattered cake plates everywhere, and the crumbs, as if they were heavenly treats; in regards to her sister, that's what they probably were, actually.
"...Okay, I won't lie to you, sister; I'm on my tenth delicious, moist, and heavenly cake, Lulu. That's...Not bad, right?" Luna recoiled violently at the number that she was given; now that was going too far! She didn't expect such a large number of cakes, and this was supposed to be a 'midnight' snack, for Faust's sake!
"FOR THE LOVE OF-"
"Lulu! Inside voice!"
Luna snorted as she strode up to her sister, and looked at all the scattered plates and crumbs. "Tia, how can you possibly eat that much cake as a snack?! How does the kitchen staff even manage to provide you with all this cake anyway?! Do you have some chefs dedicated to only making you cakes?"
Celestia began to consider saying something before opening her mouth, and then closed it again, obviously not wanting to give her sister an answer; Luna's eyes grew wide, and the look of amazement, horror, and wonder of thinking about such a thing gave way to a wide grin; Celestia watched in horror as Luna giggled softly, and winked at her, planning something very, very bad for her.
"Does this mean I finally have some ammunition against you, sister? What would your ponies say if I told them you had an extreme fondness for cake at night?" Unfortunately for Luna, Celestia was very, very crafty, and quick to think on her hooves; one had to, after all, especially if you didn't want your little sister spreading word of your eating habits.
"If you dare mention a word of this outside this kitchen, I'll have you know first that they make and individually wrap all those moon pies for you, so if you dare to breathe this out to other ponies, I'll simply have my chefs stop making the best moon pies in Equestria for you." It was partly a bluff, since the royal cooks didn't actually make her moon pies, but they did buy them from only the best bakeries, which just so happened to also be owned by Celestia, in the case that she wanted to eat cake in private and not in the castle; a rare occurrence, but sometimes she liked eating cake in other locations.
That got Luna's attention, and she looked at her fridge, stocked full of those delicious moon pies, and then back to her sister, who wasn't smiling, with her poker face back on, and she couldn't find a crack in it this time; she realized then that the only way to keep those heavenly pieces of ambrosia would be to agree to her sisters terms, unfortunately. Sighing, she lifted a hoof up, and smiled weakly at her.
"I promise not to say a word about you cake 'team' if you promise not to stop production of my moon pies."
"I agree to those terms, Luna." Celestia extended a hoof, wrapping it around Luna's outstretched limb.
"I do not like it, however; this is an uneasy compromise, sister." Celestia rolled her eyes, and smiled sweetly at Luna, happy that her semi-bluff worked on her.
"All compromises are."
"Fair enough."
The deal settled and the compromise made, two sisters left the kitchen happily with each other for different reasons each, but both also forgetting the half-eaten cake that some poor pony chef would find later.
