Prince BlueBlood was in an unusually giddy mood lately. A smile plastered on his face and his hooves stepped with a bounce in them. Even the boring routine jobs he had around the castle weren't phasing him. This was all because, at the end of the week, he; Prince BlueBlood, nephew of Princess Celetia, would become the new ruler of Equestria!
He could hardly keep himself composed upon hearing the news. It was always assumed his cousin Princess Cadence would become the ruler, but then the Crystal Empire appeared and she left. He had of course gotten his hopes up, but that died when Twilight ascended to an Alicorn and became a Princess. So he continued his life just the same, with the irritating knowledge that a pony who wasn't even born into the royal family was going to become ruler of Equestria. But then she went and got her own castle! In Ponyville! of all places. Ahaha, the fight she and Celestia had when his Aunt had told her she needed to move back to Canterlot if she was to take over reign of Equestria. Twilight refused to leave Ponyville and her friends, saying that she didn't want to rule Equestria if she had to leave them. Which left Celestia and Luna one last candidate if they ever hoped to retire; Prince BlueBlood.
It was announced that he would be the new ruler and his coronation would be at the end of the month on his 21st birthday. Three weeks had passed and things were coming along nicely. The dignitaries were due to arrive tomorrow in time for the Grand Galloping Gala, and he was just about to head into town to buy a new suit. He was even thinking of commissioning a custom made one for his coronation.
Prince BlueBlood was just about to trot out the castle's front doors when two looming shadows fell on him. Looking up, he saw his two Aunts; Princess Celestia and Luna, smiling down at him.
Bowing, he greeted them;
"Good morning Princesses."
"Good morning Prince BlueBlood," Celestia replied, "Where are you off to today?"
"I was about to head into town to buy a new suit for the Gala tomorrow."
"Good thing we caught up to him now, sister. What a waste of bits it would have been." Luna said. Celestia shushed her quickly and smiled down wider at BlueBlood as she guided him with her wing to turn around and walk with them.
"What Luna means is, there's no need for you to buy a new suit right now. Come, we have something to discuss with you." Curious, but silent, BlueBlood followed his Aunts into a private room where they could talk.
"What was it you wanted, Princesses?"
"Oh Please BlueBlood, you're to be coronated at the end of the week, there's no need to call us so formally. We're your Aunts, just Celestia and Luna are fine."
"Alright, but pardon repeating myself..."
"BlueBlood, have you ever noticed the history of Equestria's rulers?"
"... I don't understand."
"They're all mares. Ever since the tribes united and became the Equestria we all know today, the ruler has always been a Princess. You're the first Prince to rule since Princess Platinum's father; the Unicorn King." Celestia explained.
"And he was denounced when it was revealed he was using Earth Pony slaves to mine the tunnels in the Canterlot Mountain." Luna added.
"Why hasn't a stallion ruled before now?" He asked.
"Because they can't be trusted." Luna stated so coldly it made BlueBlood's stomach turn. He looked to Celestia and she too was glaring down at him.
"Never has a ruler of Equestria had a colt for a foal, everyone with royal blood only ever has fillies. It was a spell cast long ago to ensure the throne would only go to a female." Suddenly Celestia turned on him, "But then you happened, the mysterious variable, an outlier, the one that shouldn't be, the accident. Although we were confused, we decided to forget about it, afterall, we had candidates already."
"But why? Why can't a stallion rule?"
"Because stallions are susceptible to greed and become power hungry." Luna stated," Discord, King Sombra, Tirek; all examples of stallions who were rulers, but ultimately caused trouble. Mares have a natural nurturing side to them due to the fact that we are mothers. We care for our subjects like children and would do anything to help them. Males don't have this nurturing nature. They see only subjects that they can control and hold power over."
"So you can imagine our apprehension when we decided to make you the new ruler." Celestia said.
"But we've been doing this job for so long, we couldn't take living through another lifetime trying to teach another pupil to become the next Princess so we could finally have our retirement." Luna sighed.
"With failures like Cadance, Twilight and Sunset Shimmer, we really couldn't take doing it all again." Celestia said while listing the names off on her hoof.
"So grudgingly, you have been chosen to take up the mantle." Luna walked closer.
"But we still couldn't shake the nagging feeling that you may become a corrupt ruler." Celestia came closer.
"So, we have been looking for ways to fix this." Luna grinned.
"And we've finally found it." Celestia said leering over him. BlueBlood's heart was pounding, what was his Aunts saying? Were they replacing him? Were they going to brain-wash him? What?!
"Wha-" His mouth was covered by a large white hoof.
"We've decided, that you're going to become a mare." BlueBlood stared up at them, his eyes bulged, and his jaw dropped. Quickly he paced away from them, walking backwards into the wall.
"Y-you don't mean that?! Do you?! You can't! Tha-that's not possible!"
"Of course it's possible!" Celestia beamed.
"Using Alicorn magic that is." Luna added.
"Yes, it's a spell only Alicorns can perform, and it just so happens, we have two right here."
"But I don't want to be a mare."
"You want to rule don't you?"
"Not if it means you're going to change my gender!"
"Listen BlueBlood, being a mare isn't horrible, it has some perks. Like ruling Equestria for example."
"No!"
"No? Hahaha, look Luna, he thinks he has a choice."
"Foalish isn't he?" Celestia strode up to BlueBlood, her face pressed against his as she glared into his eyes.
"Look here you little.. My sister and I have been ruling this nation for over a thousand years! I think we've earned our retirement. So it makes no difference if you want this or not. You will be a mare, and you will be the next Princess! Got it!" A small whimper escaped his mouth. "Great, now that we've got that sorted. Sister?" Celestia stood back as her horn started to glow. Luna's did the same.
"Wait! You're doing this now?!" He tried to bolt from the room, but he was picked up in a magical grasp, unable to run, unable to fight back. His vision went white as his body was encompassed in magic.
