A Monster Star AU (introduction and background)

AN: Do you know what AU is terribly missing from most fanfictions? Monster Star! This is to introduce the history of the AU with Eclipsa. Star is briefly introduced at the end.

Eclipsa was a queen of Mewni that had many nicknames. "Monster lover" was only one of them. The other significant one was lost forever to the history of the kingdom. For the safety of the kingdom, a forbidden spell was removed from the book of spells and buried deep into the archives. One cannot truly get rid of a spell. One, however, can hid it deep underground.

The citizens during her reign were absolutely furious that she had made love with one of their enemies.

"A brute!" one of them had cried out. "She made her bed with a brute!" The farm workers began to riot, the nobles turned their backs on her, even her children ran away. Her former husband planned a coup to wrestle control from her. Mewni prepared for a civil war against the dark witch but it never came. It never came because Eclipsa had a plan. A plan so evil that the history of it had to be removed from all archives in order to make sure it never happened again.

In order to unite the Mewnians and the monsters, there needed to be a common enemy. But not just a regular enemy, this enemy needed to be something that can only be defeated if monsters and Mewnians worked together. One night, she completed the necessary rituals and created the first of their kind, a vampire. Vampire are strange creatures. One can categorize it as a monster, but a vampire is also human. Can something be both a human and a monster?

It was a special type of vampire; it could turn anyone else into a vampire with a single bite. At the time of its creation, there was one. By the dawn of the next day, there were a thousand. The first vampire took ten bites, the second one took nine, the third one took eight, and so on.

The royal courts heard the worries from the monsters but paid them no mind.

"They're just monsters," they said. "They're not under our jurisdiction."

And so another day passed and the night began again. There were a thousand. And by the dawn of the next day, there were hundreds of thousands. Both Mewnian and monster alike were overwhelmed and turned into bloodsuckers. The citizens who expanded out into the forests were all gone. Those that made it out alive had to rely on monsters. And so began the plan.

The forests were now swarmed with vampires and the monsters were denied entry into the Heartlands. Eclipsa was smart enough to place holy magic around the kingdom so that the vampires couldn't go in. She declared Mewni to be in a state of emergency and created an army to fight the vampires. A scouting group went in. They were never seen again.

The next day, another group went in. They were also never seen again. And so on and so forth. But one day, a group did come back. They were with a two monsters. The survivors told the kingdom of how the monsters helped them to distract the vampire long enough for the soldiers to kill the abominations.

Two groups were ready to go into the forest, with one of the groups having monsters in it. Deep mistrust was still present, but Eclipsa knew that it would be gone soon. Once again, the group with the monsters survived. As the number of groups began to increase, she made half of the groups always include monsters. As always, the group with the monsters in them were the only ones that survived the trip into the forest. It even got to the point where soldiers asked for monsters to be included if they weren't already.

One day, the queen made an announcement that would forever change the kingdom, the creation of the Mewnian-Monster Pact. Essentially, the pact stated that the monsters would help the Mewnian soldiers and would be able to stay in Mewni in return. Surprising, nobody complained. If it was something that could help them survive, then they would accept it.

The war against the vampires ended three months later. Both monsters and Mewnians got along with each other, their past feuds forgotten for the time being. Eclipsa's lover was named a hero and everyone cheered. By now, everyone was too exhausted or too relieved to care about it. However, there was an unnamed Septarian who was absolutely furious. He knew the truth, that the queen's lover was a coward.

One night, he decided to take matters into his own hands and planned an assassination. Right as he was about to enter the bedroom, a young girl appeared before him. She had bright orange marks that looked like the sun on her cheeks.

"What are you doing?" she asked.

"I saw an intruder walk into the queen's bedroom and wanted to make sure nothing happened," he replied.

The muffled sounds of giggling and flirty could be heard from the outside.

"Oh, it's just father," the girl said.

"You don't look to happy about it."

"I don't like him. I wish my real father could be with me." The girl turned around and walk down the hallway.

"After tonight, you'll get your wish, girl." He opened the door and went it. There were three inside the bedroom that night. And in the dawn, there were two cold bodies lying on the ground. The Septarian succeeded in killing the monster, but paid a heavy price: he would be forever stuck in the depths of hell.

The next morning would prove to be her undoing. Her former husband had planted a device inside the bedroom to listen on her conversations.

"Oh, you're so devious, my queen," a deep voice said. "But that's why I love you so much."

"Of course I am. Did you think otherwise?" Eclipsa replied.

"How did you ever think up of such a plan?"

"It was simple. Enemies become allies when there is a common enemy. All I needed was an enemy that could only be defeated by Mewnians and monsters fighting alongside each other. And vampires were just the right thing for the job."

"My fellow men and women," the former king said. "Listen as your queen spells out her plans. She did not care for any of us, but used us for her own selfish needs. She has even used our fellow friends, the monsters. She unleashed an unspeakable horror upon all of us and for what? So that she could make her bed with a coward! Her lover was nothing more than a scared child in the battlefield and I have proof! Listen to what your soldiers say about him and how he ran away with his tail between his legs, whimpering like a puppy!"

Soldiers came up along with monsters to attest to the claim.

"We went in and when the battle was over, he was nowhere to be found," said a Mewnian.

"His scent was faint. He clearly ran away," said a monster. "And I should know, I can smell up to three hundred feet away.

As more and more evidence piled up, the entire kingdom became furious. That day, a coup d'etat was staged. The Mewnian kingdom (kingdom now included monsters) had lost half its fighting force fighting the vampires. At the end of the coup, the fighting force was down to a mere two hundred soldiers. The kingdom was now crippled. Solaris was made the new queen and the kingdom was rebuilt from the ground up.

Eclipsa had betrayed her own kingdom for a lover. But on the other hand, she helped Mewni to achieve what was thought of as impossible: peace with the monsters.

…..

Generations later, there was a princess by the name of Moon Butterfly. She had become fast friends with a Septarian by the name of Toffee. Toffee was a renowned lawyer who made his way up into the royal world. Moon also had a man pursuing her heart, River Johansen.

The Johansen Kingdom was to the east of Mewni. It was primarily ruled by a barbarian clan who still had a deep seated distrust of monsters.

Moon had fallen in love with Toffee instead and River tried to change her mind.

"Aren't you afraid of being called a monster lover?" he asked.

"Of course not, there are plenty of families with monsters and Mewnians in them," she waved off his concerns.

"But he's a monster!" he protested.

"And what's that supposed to mean?" she glared at him.

"All monsters are evil! Did you forget how many of your people they had killed in the past?"

Moon sighed and explained to him what really happened. River, however, was unrelenting and brought it up at every opportunity. Evidence from the Johansen Kingdom's books, stories told by tongue, and etc were used in an effort to persuade Moon from being with Toffee. Eventually, Moon snapped.

"And a barbarian like you would be better?" Moon scoffed.

"Better than a monster!" River yelled.

"I've had enough of you," she snarled. "I tolerated you at first because I had hoped that you would change, but you're just a stubborn mule listening to outdated tales! From this day onward, you are banned from Mewni!"

Years later, Moon and Toffee would be married. After nine months, a baby was born. A girl that was the first princess with mixed blood, Star Butterfly. She had blue-gray skin and a lizard's tail. Her irises were light yellow-green on the bottom half and light blue-green on the top half. On each side of her cheek was a dark red heart.

On that day, River swore that he would have his revenge.

…..

Star was now fourteen; she had white-silver hair that reached her knees. Her teeth resembled her father's sharp teeth. She was currently wearing a dark gray dress. She jumped up and down in excitement for what would happen today; she would receive her mother's wand.
