I had to do 3 rough drafts of this.

My head is certainly not in the most luxurious state. The only way I can describe such a rough feeling is with a sword through my head. Metaphorically, of course, an actual sword through a skull would be much more agonizing. Much more agonizing than that pole dancing class I took in St. Olga's...why do princess need a pole dancing class? Never really bothered.

And hot, why is it all of the sudden so hot for me? Must be a fever, must've been from that spell. All I can remember was being hit by some spell by Star. And that is it. No memories of how it happen, or any memory pertaining to that day. I can recall the terrible time River tried to annex the Party Lounge to Mewni, needless to say, he got something in return from me, but that was the prior day. I should really limit her use of the wand, maybe teach her not to use the wand, maybe lessen the need of magic, even tell Glossaryck not to teach a few times. She is really the rambunctious child at times. Causing mayhem and havoc wherever she steps and where ever she gazes upon. At my time, I would wait for the castle doors to be opened for me, patiently waiting on the other side and earning my wand, instead of riding a unicorn through the castle doors then creating a bit of ruination in less than one day. Maybe One day. One day, Moon.

The Kingdom isn't going to rule itself, Moon. Maybe River can rule it for one day...Oh, such folly, of course, River can't rule it. If there was ever day that he would rule alone, that would be over my dead body. He'll probably attempt to annex Party Lounge again. Maybe it's time that I get up.

I felt my groggy eyes open up into a blur. I rub my eyes a bit and I am welcomed into a rather unfamiliar environment. Certainly a Mewnian room, but certainly not mine. It was rather disturbing than welcoming. The room was messy to my taste, clothes and random trinkets just lying on the floor, and not where they belong. Pictures were poorly taped to the wall, and one wall had weapons on display. It even smelt like a mutt had rubbed itself over the furniture. There was even a calling mirror attached to the wall...I'd say I'm in one of River's niece's crib.

I ran a hand through my hair, but to my surprise, it was silky soft, rather than it being coarse and damaged. Not even a hair extension. I touched my face a bit to a marvel, my face was soft. Not crinkly, ragged, filled with makeup and crevices, no, it was genuinely soft. Even my back, I can't seem to feel that ache again it seems. And my wings felt...absent. The Butterfly family have some troubles on the idea of holstering their wings, but it was absent for some reason. Yet they enjoyed having their wings rather tucked than free. Huh, whatever spell Star used felt pretty welcoming. Still, I need to lecture her on using those kinds of spells.

The door swing slowly as I saw both Star and River stick their heads through with a forced smile, ear to ear. I could already tell something wavering was in plot. Just need to know what they did. Star walked forth, taking careful steps towards me with River mimicking her steps. Sweat dropped from the both of them and keeping that dreadful smile plastered on their face. It was painfully obvious that they were hiding something. Only time will tell now.

Star approached to the right side of the bed, and River approached the other. She starts to titter a bit before she opens her mouth, "He-hey Mom! How are-"

"Hello, honey-" River interrupts.

"Oh, you're talking first hehe-"

"Whoops, my bad."

"No, no. You go first."

"Are you sure dear? I-I mean."

"I am sure. You know what, I'll go first hehe."

River and Star mumble to each other, completing each other sentences, and exchanging gestures, as I try my best not to roll my eyes in disdain. It isn't the proper Mewnian norm, and certainly not the way of a Butterfly.

"So Mom...how are you?"

"I don't know YeT, StaAAAaaarrRRRrr?"

I opened my mouth to greet my only daughter, then I shut my mouth quickly. This wasn't my voice, my own voice was higher than usually. As if someone just punched my throat in, that wouldn't be pleasant. Still, I didn't sound like some fifty-year-old queen, no, I sounded like a fifteen-year-old princess. I sounded like, like...Star? Preposterous. I have to make sure one more time.

I took a greedy intake of air, as I prepared to test my voice once again.

"QUEENMOONTHEUNDAUNTEDTHEIMMORTALMONSTERWILLBEHAUNTEDBYTHEDARKESTSPELLOFMOONTHEUNDAUNTED."

I quickly blurted my entire tapestry quote without takes. My voice remained unchanged. I sound forty years younger than I should sound. Of course, they pulled something off this time, and it looks like my theory of me being a victim of either the two's chaos is out the window. One of the two screwed up, now it's time to find out who. I'll be happy that the only thing they changed in me would be my voice. I know the two can't pull off something much worse, I can only think of the sore disappointment. Now they begin with nervous laughing as they notice how my eyebrows furrow and they're probably thinking of punishment I have in store for them. No, no. I have to wait for their excuse, pitiful maybe.

Star cleared her throat and asked in the nicest tone she can muster, "So Mom, how are you doing?"

I only gave a deadlock stare. Seeing the little tiny fear in her eyes, I bluntly replied, "Great."

"Are you mad?"

"Yes. I am mad."

"So-"

"What did you do this time?" I crudely interrupted her as she twiddled her fingers behind her back. She opened her mouth, then close it without proper response, only a mutter of an initial, and this would repeat itself in a pattern.

"Do you remember what happened yesterday? Dear?" River asked.

I tried one more time to remember the events from yesterday, but to no avail. I told him, "Frankly not River."

"Are you sure?"

"Do you remember our time in the Tapestry Room?" River blushed a bit when he said that.

"Yes, I am sure. I do not remember."

Star dipped her head into my view, "Are you really, really, really, really, really-" Star repeated her words.

I objected to her repetition, "Yes. I. Am. Sure." I made myself clear with a little apathy dripping from my voice. Star retreated back to her side. It successfully made their grins leave their face.

They traded nods before River brought up a mirror behind his back. He coughed into his hand and started speaking in a stoic manner.

"Do you feel any younger anyhow my dear?"

"Any younger. Why?" Moon questioned her husband.

"Well..." River didn't finish his sentence as brought the mirror up to Moon's face, "Take a look for yourself.

"Waaaaaaaaaaaaaaaaaaaaaaa…" Moon only awed at the sight of the mirror.

Moon's complexion was no longer rigid and stressed, but her face was young and soft as she touched her face. The hair she has is now a pure sky blue, with no hints of dye anywhere. The style of it was free and it possibly reached to her knees, with three bangs on the front, one brushed to the right and the other two to the left, unlike her regularly poised and gelled hair. No signs of makeup on her face to cover any wrinkles, her face were all natural. She really did look like Star.

Her appropriate reaction was her mouth wide open with awe, eyes sparkling in the beauty of the beholder, and her thoughts all to herself. This awe was mistaken by Star and River as their sides of the bed. Moon nudged and brushed her face, feeling the smoothness of her face, letting her narcissism take over her. The two would soon slowly rise from the sides from the bed, with a hunch that Moon is no longer mad.

Star looked at her mother, no longer with shock, but with awe on how her very mother lying on her bed looked exactly like her. Believing that her merry expression made her no longer ticked, she kindly asked, "So Mom, are you still mad at me?"

"I am always mad at you," Moon replied bluntly without hesitation, even when occupied at admiring herself.

Star released a disappointed sigh, "Of course you are."

Moon released a few chuckles at that statement. She enjoyed the moment, but she knows that all good moments come to an end. Moon knows she can't let River rule Mewni alone, it can't simply happen. Who knows what havoc would reign over Mewni if he was under control of the two thrones? She looked at her husband who remained dreary at her presence and said, "Well now River, turn me back."

The words alone made River and Star traded glances as they made more nervous chuckles. "Well Moon, I can't turn you back."

Moon let out a small chortle remembering the magical capabilities of her husband. He has none."Of course, what was I thinking? Well then, Star, call Glossaryck, he'll know what to do."

When Moon called to her daughter, rubbed the back of her head as if she was searching an answer in her hair. "Well, Glossaryck was here just last night."

"If Glossaryck was here last night, then he must've seen me as a teenager? What did he say?" Moon questioned her daughter.

Star tamed the nervous laugh and put a much more sympathetic one and grabbed her arm as if she was giving bad news. River just looked down on his feet. Moon just stared at her daughter, waiting for her answer, waiting for her fix on the situation.

"Glossaryck said...he has...well...no solution."

"What do you mean?"

"Well, you said yourself 'yesterday' when we were in the tapestry room together in which you don't remember. The spell wasn't made by one a blood-related Butterfly, nor was it of the known dimensions, therefore he said he had no answer. Not even a riddle." River explained, but Moon remained unsatisfied at it.

"Call the High Magical Commission then." Moon's swift yet stoic response broke the unfocused gaze of Moon and Star. River gave a disdainful sigh.

"They came in but they had no solution."

"Not even Hekapoo? Not even Omnitraxus?" Moon questioned her husband as he nodded his head in denial.

Moon always had the idea that the High Magical Commission could solve anything, but they couldn't even solve her transformation. She pondered a bit on who should be left on charge: Lekmet or Hekapoo, maybe Omnitraxus, but not Rhombulus, he was simply a helper to Lekmet.

"Well if you can't turn me back, I'll-"

River halted her as he held his hand up, telling her to be silent, "You're not allowed to make choices, your mother has assigned me to be the prime minister for the due time until…"

"My mother? Prime Minister?" Moon questioned her husband. "River you know Mewni has not had a Prime Minister since…

"-Queen Eclipsa, the Monster Lover. And that is why they have asked me to step up as one." Her husband finished her sentence with a hint of sympathy in his voice.

"Yet my mother made the choice?" Moon furrowed her eyes a bit.

Even though the rule of Moon and her mother was extremely similar, with the exception of her being much more merciful, was the ridged relationship between the two, most likely for sending her to Saint Olga's for being a rebel. She promised herself not to send Star there, but she can understand what it is like to have a little rascal under her arms. Moon probably forgave her mother years ago, but she can't overcome it.

"I know you despise your mother, but I couldn't make the choices for you. She was here when she made it."

"Then what is to become of me?"

"Since you're now fifteen...it was a choice of me and your mother to...well...how should I say this?" River scratched the back of his head until he noticed Star on how giddy she was. She was jumping up and down for joy with her eyes as wide as frying pans.

He sighed and lifted his hand up towards Star, knowing that she wanted to break the news he already knew. "Take it away...Star."

Star made a little celebratory jump and whispered a yes to herself. She looked at her mom who just gave an uncertain look. "Soooooooooooooooooooooo-Grandma Luna told me now that you are younger."

"Yes, I can tell."

"And you know how you're fifteen again," Star said with glee.

"Yes, I am fifteen again."

"Then she said how she had a great time with Aunt Felicity, but you grew up alone?"

Moon gave some signs of disdain on her face. She hated that fact. Having no one to adventure with at times or get punished and sent to St. Olga's made her feel quite lonely. Moon narrowed it down once again, "I was an only child for my childhood. What are you leading up to Star?"

Her question made Star jump right in front of Moon's face with her still oblivious of what is to come, "You know now how I am an only child myself?"

"Yes and I really wanted you to have a sibling, " Moon said disappointedly "River couldn't give me one, unfortunately."

River immediately noticed her quirky remark, "Hey wha- HEY!"

Moon giggled at his upset words. Star ignored Moon's last words, not understanding what they meant, she continued, "Grandma Luna has made you my…"

Star quickly jumped on the bed, nearly hitting Moon who already lying down, as Star took a deep breath. Her hyperactive behavior made the latter at this point was ready for what she was going to say.

"TWIN SISTER!" Star exclaimed as her arms shot up into the air. Clearly excited about what her grandma has chosen. Moon shook her head, clearly frustrated at that decision.

"No. That must be a mistake. I must be heading back to Mewni at this instance," Moon declared which made Star's jovial look instantly change to a frown, "I can't just suddenly become your sister Star. I hope you understand."

Removing her legs from the blanket, Moon set her feet on the cold floor. She took a quick glimpsed at the mirror nearby to see herself dressed in the same clothes as the tapestry room. The same blue dress, just missing the tiara, wand, and Lil' Chauncey. She shivered a bit until she stood up and began her first steps as a fifteen-year-old. But as soon as the first step, she fell over forward, catching herself on her arms.

"Hm. If the Queen of Mewni can't walk on her own two feet, then she might as well need some help." River said as he walked over to Moon's side and offered her a hand.

She grabbed it and was gently brought up back to her feet. The King smiled at his daughter on the bed and said, "Star, can you give us some time alone."

"Alright. I'll be downstairs if you need me. Eating nachos." Her answer was plain and boring, she was clearly disappointed at her mother's decision. Moon did show some signs of sympathy as Star got down from the bed and passed the both of them.

Upon exiting and closing the wooden door, River sat his wife down at the bed who just looked down. He approached on her left side and sat down, then wrapped an arm around her shoulders. Moon on the other hand just laid her head on the chest of River.

"Look, Moon, we had no choice when doing this. And look at the bright things when you're her sister. You'll be on adventures together, do magic together, maybe fight monsters. She already practiced her part," River proudly said to her as she kept her head low, "I know you're reluctant and maybe you may think otherwise, but I promise you, you're helping your daughter out in a phase of her life. She may want someone on her side, maybe that Diaz boy, but someone else as well. I understand you're in between a rock and a hard place, but you're helping her become Queen. So?"

Moon absorbed each word carefully, understanding each of them, as she stared into nothing. She was giving her thoughts through on each positive and contra to what is to become of her. Before mustering every single thought, she finally gave her verdict, "Ju-just. Promise me you'll fix this soon. And keep Mewni safe..."

"I promise." River assured his 'daughter' as he rubbed her arms for comfort.

He then released her as he stood up in front of her and looked her into the eyes. "Since you're my daughter now, I guess everything that applies to Star, now applies to you."

Moon simply smiled at those words, "I'll watch Star. I'll make sure she won't hurt herself."

River placed an arm on her at the assurance of her words, "Thank you, Moon. I've already set you up for the same school as Star. Star has a chest with all your stuff in it. I do expect the both of you to get along."

River started hugging Moon, as she returned it. As a few minutes passed, River broke it and pulled out a dimensional scissor. For the appropriate, Moon pulled his husband in and kissed him on the cheek.

"Good luck, River."

"You too, darling."

He gave one last smiled before he sliced a hole in space and time fabric and went through it. Moon, now left alone, stood up, and walked without ease towards the door and opened it. She was now in a foreign environment. And she had to get used to it.

Navigating through the halls, she wandered through the house of the one she set Star up with. Finally finding the stairs, she walked down until she heard a faint conversation.

"Star, Nachos at 11 in the night isn't healthy, and besides, school is tomorrow. We gotta get up early tomorrow.

"I don't care Marco. I just don't."

"Why? Something happen?"

"Just don't."

"Is it Oskar?"

"No, it's not Oskar."

Moon could hear Star's grief all the way up the stairs. Wanting to do what's right, she gulped a deep breath and exhaled it, making her nervousness leave her. Walking down the stairs slowly, she heard more words supposedly for her.

"Mom. Where'd you put those darn nacho shells? I've been looking for them."

Moon didn't understand what in Mewni a nacho was so she just approached the wooden table on where Star placed her head down. The boy was shuffling through the cabinets, looking for the nachos. Pulling the chair and sitting herself down next to Star, who didn't notice her presence. She stared at her 'sister' who kept her head down, grieving of what has happened moments ago.

"Ahah, found the nachos. Who are you? And why do you suspiciously look like Star?"

Moon broke her gaze to see the boy pointing his finger at her. Before Moon spoke she repeated in her mind, "You're no longer the Queen of Mewni, you're the twin sister of Star Butterfly, Moon Butterfly."

Clearing her throat, "Ah yes, I am afraid Star made no proper announcement of my arrival. I am Moon Butterfly, the twin sister of Star Butterfly," she stood up and bowed before him, "Pleased to meet you, Marco Diaz."

Marco blushed a bit, until Star heard those words, as she slowly looked up to see her twin 'sister' standing right there. She made the biggest smile, with no signs of grief anywhere on her. Her pupils enlarged and shined.

Moon didn't give a lecture about showing behaviors like that, she simply smiled and bowed at her, "Hello, Star."

Clearly happy at the moment, she literally jumped and hugged Moon, who did nothing and returned the hug. Star felt like crying tears of joy, but she couldn't. She had low expectations, but expectations nonetheless that she would accept the offer. And the miracle came true as she did. Star repeated a few appraisals before getting off of her. Marco, on the other hand, was clearly confused at the moment, Star's twin sister comes out of nowhere and Star just jumping at her. It was clearly weird.

"Welcome to Earth, Sis!"
