Chapter Text
"Marco Diaz is Dead!" Star screamed, setting the viking-style pyre aflame in the Diaz backyard. "Long Live Marco Diaz!"
"Star. You don't have to do that."
"But Marco is dead! You have to understand that, Marco! We need to remember him...them. We need to remember Marco Diaz."
"Star, I'm still the same person! It's just that we all know that I'm a girl now. It's fine." Marco wasn't sure what she expected from telling everyone she was a girl, but she certainly wasn't expecting a viking funeral. Considering how gleefully her parents had decided to don viking helmets and sing as the pyre and the suit-bedecked straw dummy burned, perhaps she really should have. Star was great at convincing them to go along with whatever she wanted to do.
Two years had done a lot in terms of toning Star down from Life-threatening fourteen year old recklessness every minute to Life-Threatening sixteen year old recklessness every other day. The change was impressive when you compared it to fresh-from-Mewni Star. Time couldn't tame the core of Star's personality though, and it was all excitement all the time. All excitement and great ideas, viking funeral for the boy she had never been included. Marco smiled when the suit wearing dummy properly caught fire and began spewing fireworks into the afternoon sky, sending Narwhals and kittens flying from the glittery center. Thankfully, the neighbors were pretty deaf and great at ignoring them.
All this to celebrate a gender change on her driver's permit, she considered as she side-stepped a falling narwhal, Marco couldn't wait to see what happened when she started on her Estrogen regiment next month. It was a shame her parents would be taking her back to Mewni today and Star wouldn't get to see it. Maybe she'd pop in anyway? Star was more responsible than she had been before, but more responsible didn't mean unwilling to skip out on meetings or exams to celebrate an important day with her friends.
Then Star's mirror began to chime.
It was semi miraculous that Star could hear it at all over the sound of magical narhwal-unikitten fireworks but she was kind of miraculous by herself, so that was fine. Star barely checked the caller-id before she was shouting.
"HI MOM! HOLD ON, LET ME-" Star spun towards the Diaz's and her wand set the fire from burn to vaporize, turning the pyre to ash and cinders instantly. The lingering heat dissipated with the fire extinguished. "Okay, yeah, what did you want?"
"Star, your Father and I will be through coming shortly."
Almost instantly a pair of dimensional scissors cut through the fabric of reality and a carriage pulled by Giant Invisible Goats rolled through serenely, at odds with the incinerated funeral pyre, which had already been at odds with the Southern California stucco neighborhood. It sparkled and glimmered as Star attempted to bolt towards it. Marco grabbed her by the shoulder, stopping her dash before it started.
"Wait for it, wait for it...." After a long moment the door slowly opened, a blue silk walkway pouring out ahead of its passengers. King and Queen Butterfly finally stepped out onto the blue silk. "Now," Marco said, unleashing Star upon her parents. Star sprinted as fast as Mewmanly possible at her parents and squeezed them until even Queen Butterfly's stiff back looked like it would bend.
"Haha, wonderful! It is such a long time since we have seen you!" Raphael Diaz carefully adjusted his horned helmet as he patted King River Butterfly on the back {well, slammed really, because King butterfly is a short man and Mr Diaz was pretty large and semi unaware of his own strength}.
When The Butterflys had been settled down onto the couch and snacks had been passed around the Diaz'z and the Butterflys began talking. Marco and Star sat, sides pressed together soaking up as much friendship as they could stuff into their Human and Mewni bodies.
"Thank you again for hosting Star for us," Queen Butterfly said primly.
"It was no problem at all. We loved having Star around. Didn't we, dear?"
"We sure did! I made a statue of her face, you know!"
"You did?" Queen Butterfly looked only passingly interested. King Butterfly was stuffing his face with taquitos.
"Ah, yes. Sadly it was broken when Star had an accident with her wand. She said sorry so many times we had to ban the word in the house for a week, you know!" Now Queen and King Butterfly were interested.
"She apologized? Really? I don't think she even apologized for crashing a Warnicorn through my vanity on my birthday. Truly, you seem to be excellent influences. You must have raised your own child so well!" Mrs. Diaz turned towards Marco, who was sitting with Star, and hugged her tightly.
"Yes, Marco's our little Princess!"
"I apologize for not checking your status before we had Star board with you. We were unaware you were royalty."
"Nah, Queen Butterfly, we're not actually royalty. It's just a nickname. We're just regular people," Marco shrugged casually.
"Well, that certainly is a shame. Please, allow me, on behalf of the Mewni Kingdom and the Butterfly Legacy to grant you a gift for hosting Star so wonderfully."
Mr. and Mrs. Diaz turned towards each other. They had enough reason to be wary of magic, having seen Star use it for three years. On the other hand, they had seen Star use magic for three years and knew that it could do some amazing things. If Star could grant them laser-puppies and add new rooms to their house as an energetic, and untrained teen, then the much more responsible Queen Butterfly would surely be able to not destroy things when she gave them a gift. Besides, the gift might even be more practical than having a water-slide for stairs, even though they had enjoyed that for a while. The Diaz's turned their heads back to the King and Queen on their sofa and nodded, smiles wide on their faces.
"Excellent! Star, if you would hand me the wand please?" Queen Butterfly held her open hand out expectantly. Star got up and walked over to her mother and handed her the wand, Handle first because Marco said it's safest that way and she really wanted to impress her folks by being super safe.
Queen Butterfly took it and shook it a few times, until it became blue and gold, with a broken, blue crystal heart at the top. Paying no heed to Star bouncing excitedly next to her, Queen Moon Butterfly, stood and began to wave the wand in elegant patterns above her head.
"Orbis terrarum regni est. Magica primogenita tua. Ego dispono vobis regnum!" The wand began to chime a series of crystalline notes and began to glow until everyone had to shut their eyes. Marco felt magic wash over her, cool and gentle. It was like standing in the ocean,whereas Star's magic felt like someone invented an Electric Grapefruit and shoved it into your mouth.
The magic went from a tidal wave to a river and eventually slowed to a halt. Marco pulled her hands away from where they had been shielding her eyes to look around the room. Nothing was broken. No one new was in the house. The walls weren't breathing and her arm wasn't a tentacle. Marco had approximately negative two ideas what exactly that spell had just done, but it was big. She knew that much despite not knowing what exactly it did.
"Woah."Star stood, staring wide-eyed at her mom. Marco wondered if Star would be as powerful when she got on the throne."Marco!" Star yelped, breaking Marco out of her thoughts. "Your face! Marco, you have spirals on your cheeks. Mrs. Diaz, too! You're just like us now!"
Marco and his mom looked at each other immediately. Star hadn't been kidding. Where Star had pink hearts on her face Marco's mom had yellow spirals. Marco could only assume she had them on her cheeks, too. Star snatched her wand back and bounced over the table in a single leap to pinch Marco's cheek and coo at him. Mr. Diaz was also touching his wife's face, murmuring about how cute they looked on her. Queen Butterfly cleared her throat and the noise stopped as everyone turned back to look at her.
"I have taken the liberty of granting you the Butterfly Legacy Marks." Okay, built in fancy make-up? Marco could deal with that. She'd have to make sure her stuff looked good with yellow in the future, otherwise no big. But, no, it couldn't have been something that small with all that power build up. Unless the Butterfly Legacy Marks really needed that much power? Marco had seen Star's activate when she attempted to break Marco out of Toffee's prison. Maybe this really was all that Queen Butterfly did.
"It wouldn't do to have you go around without some symbol of your station, after all." Marco's Magic-Shenanigan senses were tingling and she had been living with Star for two years; those senses were always spot on.
"What station?"
"Your station as royalty, of course. This dimension has always been rather backwards in inter-dimensional matters and the like. Seeing as how the dimension had no pre-established royal family, you now rule the entire dimension." Marco felt her jaw drop before Star reached over and gently pressed her mouth closed. "I have also granted your family the gift of magic. No force in the universe will be able to dethrone you for several generations at the very least. Not even the Royal Wand would be able to take it away from you." There went any hope of undoing the spell.
"Additionally, the Kingdom of Mewni will be glad to be the first to welcome you into the inter-dimensional community. In fact, we would like to propose large-scale trading between kingd-"
"AAAAAAHHH!" Star screamed, drowning out her mother. "MARCO YOU'RE A PRINCESS, TOO, NOW!" Shrieks turned into giggles as Star grabbed Marco and spun in circles. The faint feeling of unreality looming over Marco became stronger as it sank in that, No, this wasn't a simple slip up that Marco could fix, that Queen Butterfly made the Diaz's the Royal Family of Earth, permanently and on purpose. Distantly, she wondered if this would interfere with her starting estrogen.
