The Day The Door Was Opened
A/N: Welcome, one and all, to the Reactsverse's crappy version of huge crossovers like Tsubasa Reservoir Chronicle, Super Robot Wars and Annihilation, the long-awaited (and probably disappointing, we all know how hyping up stuff tends to end up like) crossover between Weiss Reacts and Lucina Reacts! For anyone who did NOT read the author's notes warning you this would be uploaded as a separate story, I don't apologise, but you were indeed warned. *disapproving look*
Let's get on with the story, now that my disapproval has been demonstrated preemptively.
DISCLAIMER: RWBY belongs to Rooster Teeth, otherwise there would be a Huntress who was more idol singer-based than Weiss.
Fire Emblem belongs to Intelligent Systems, otherwise Maids and Butlers would've been in Awakening. (Lissa in a maid costume? Yes.)
All mentioned franchises and characters belong to their respective owners.
Professor Faust's Office, Beacon Academy
"Ia ia...ghgnh sktla ia ia..." Gretchen Faust chanted, her hands outstretched over a circle of candle wax, Dust and Dust-knows-what, trailed onto the floor of her office, lined with burning candles. Her small office was bare- only a small desk with a computer and a pen holder, next to a nameplate labelled 'Doctor Gretchen Faust'. A tall oaken door was to the right of the desk, leading to a staircase leading to where she really kept her supplies- essence of shoggoth, eye of newt and other unholy materials, the names of which were only spoken of in dark corners and forgotten languages spoken only in reverence to dead gods.
Within the circle, an array of symbols and runes long forgotten by most living scholars were arranged in a strange pattern- to the untrained eye, it would seem the symbols were scattered haphazardly. Faust, however, knew what she had created, and she alone still knew what these meant.
"Gretchen, you know that I find you incomprehensible at the best of times." Glynda uttered, leaning on a wall with her arms crossed, adjusting her small cape. "However, I must ask some things of you."
"Ask away." The witch did not turn to face her coworker, as she continued muttering under her breath in that ancient tongue.
"...firstly, what are you doing, and secondly, why am I here? I have very...important matters to discuss with Ozpin!" Glynda snapped, adjusting her glasses.
Faust did not respond for a moment, continuing to chant. When she spoke to Glynda again, she was speaking in a harsh whisper.
"I...am attempting to open a hole in the fragile fabric of the reality we live in, to invoke the darkest spirits from the depths of the Nine Hells. My purpose is thus- to attain advice on how to...ahh...communicate with certain beings.
And you are here to ensure that if this ritual fails, I have someone to help me banish them back to the pits."
Glynda looked at her incredulously. "So you are asking me to watch you get dating advice from hellish beings, in order for you to date who amounts to the real life Slender Man, and you did this because I'm supposed to help you kick back the inevitable demons when it goes wrong?"
"Exactly." Faust nodded without turning to her again, adjusting her glasses with one hand. "Do not worry, this is quite safe. I estimated an almost zero chance of anything happening.
And no, this is not for dating advice. I merely wish to procure...information, on how to...attract the attentions of certain beings." The witch blushed slightly as she explained.
The other instructor in the room merely shook her head. "Just get on with it. I would rather not be in here for longer than necessary! Just...d-do the ritual already, Faust, we don't have all d-day..."
Faust obliged, returning to her chanting over the circle. Glynda could feel the hairs on her back raise.
Something was going to go wrong. She could feel it.
...
Meanwhile, in another reality...
Miriel's House, Northern Ylisstol
"Yes...the last preparations are done." Miriel stated calmly, adjusting her glasses as she stared at the scientific apparatus she had prepared, pointed at the wall of her basement. "Thank you, Ricken."
The younger sage nodded, tipping his hat respectfully. "N-No problem, Miss M-Miriel...j-just here to help..."
Laurent was calmly watching the proceedings, taking his own notes.
The apparatus was a dimensional focus- a device she had named herself, having created it based on the magic around the Outrealm Gate and her mother's notes. It was rather simple- a small box of clockwork gears linked to a small stilt upon which a white, translucent crystal was set, pointing towards the wall, and another stilt mounted to allow for a power source directed at it.
"The power source my original plans called for were a focused, constant burst of energy being sent into the crystal somehow. Reflet tells me one potential source would be something called a 'laser', but in the absence of such...I have been unable to power the dimensional focus without resorting to powerful magic, such as a portion of the Book of Naga, which did not last long in my last incursion." Miriel explained to the other two sages present. "However...yesterday, I was provided with a power source."
Laurent raised an eyebrow. "Mother? What power source?"
Miriel raised an intricate golden pendant, an azure gem inset within it, pulsing gently and the colour recalling the coolness of a spring of calm water, in her hand, showing it to her compatriots before mounting it on the other stilt so that the azure gem was facing the white crystal.
"This strange pendant; Morgan arrived last night, leaving us this. The magic within it is powerful, unusually so." The older sage exposited, gesturing to the pendant. "I have come to theorise that it has something to do with the manipulation of water, but, used correctly, it may serve to power my dimensional focus.
The magic within it can be coaxed out, if only for a short duration, using a brief infusion of powerful shocks, such as one from a Mjolnir tome."
Miriel produced the said tome from her robes, causing Ricken to stare at it.
"H-how did you get it, Miss Miriel? I t-thought that was Robin's!"
"I procured it for the purposes of this experiment." The older sage admitted. "If my hypothesis is correct, the shock from this tome should push the magic out of the pendant long enough to shunt some into the focus.
The dimensional energy around this pendant should also tear a hole in reality leading directly to the world where this pendant originates from."
"...essentially bypassing an Outrealm Gate." Laurent finished for his mother, nodding. "...and thus creating almost instant dimensional travel with much smaller holes than the Gate."
Miriel had a hint of a satisfied smile on her face as she tipped her hat. "Just so."
"But wait...what if it goes wrong?" Ricken inquired, concerned. "Won't that blow us up?"
The older sage shook her head. "I have taken precautions to limit the damage to that particular wall. The only potential damage will be from a partial cave in if that wall is to be destroyed by the experiment.
If I succeed, I will firstly return this pendant, and then ask if I can find who constructed such powerful magic. If I fail, then it shall be back to the planning board with me."
Laurent frowned. "Mother, would it not be more prudent to try with a less powerful source of magic?"
"This is the least powerful source I can find that can power a protracted use of the apparatus." Miriel responded, before opening the Mjolnir tome and placing a hand on the pendant. "Both of you, away from the wall. We are about to experience what could be the greatest discovery since the creation of fire-upon-water."
Ricken gulped, standing by Laurent. "...I...have a little...a...no, a lot of worries about this. Is this safe, Miss Miriel? W-will you be safe?"
"I have done similar experiments." The older sage waved him off, before muttering quietly from the tome in her hand.
A brief flash of lightning issued from her hand and the smell of ozone filled the air, as the pendant flickered with blue light. A stream of azure issued from the gem suddenly, streaming into the white crystal focus, which began filling with the blue light.
Miriel adjusted her glasses once more. "It seems my hypothesis worked."
"...y-you sure it worked? Nothing looks like it's happening." Ricken inquired half-worriedly, half-curiously.
"Trust me, Ricken. My calculations have yet to fail me." The older sage responded, watching the focus fill with the light.
Beacon Academy
"G's pa do irae." Faust finished chanting, sweeping her hands grandly over the circle beneath her.
The candles went out, snuffing out what little light remained in the office except for a small line of light poking out behind the dark curtains. Glynda nearly jumped.
"Gretchen?"
Faust adjusted her glasses once more. "The ritual is complete. It worked."
"...what's going to happen now?" The other instructor asked, her right hand fingering her riding crop worriedly.
Faust chuckled to herself insanely, shaking her head.
"...shortly, a portal shall be opened into the deepest, darkest depths of the Nine Hells, and at last...at last I shall be able to take the council I need." The witch explained, giggling. "Is it not great?"
"...is it too late to stop?" Glynda remarked.
She did not like this situation, not one bit.
...
Ylisstol
The focus filled with brilliant, azure light, a point of light gathering at one end of the crystal. Miriel quickly jotted down her findings, frowning.
"The focus seems to be rapidly filling up with magic. This process seems to be faster than I had originally hoped." The older sage stated, a tone of excitement in her voice.
Ricken looked concerned. "M-Miss Miriel...a-are you sure this is what's supposed to be happening?"
Miriel looked to him calmly. "Put aside your fears, Ricken. You have nothing to fear. Yet."
"...t-that's what I'm worried about..."
Laurent kept his eye firmly on the wall, watching the focus gain more energy.
...
Finally, Faust could see it. A small orb of darkness had issued from the wall opposite her, causing Glynda to whip out her riding crop.
"Is that supposed to happen?"
"Just a little." Faust explained, smiling. "The portal is opening!"
...
Miriel looked up from her notebook, watching a beam issue from the focus and shooting towards the wall, causing a small pool of azure light to start expanding from the area of contact.
"The portal is opening." The older sage explained, cracking her knuckles. "It looks as if our experiment will be vindicated."
...
The glob of darkness expanded on the wall, creating a flat pool of sheer blackness on the surface. Glynda readied her riding crop. "How much longer?"
"The portal will open now! We cannot turn back." Faust declared. "Aha. Haha. AHAHAHAHAHAHAH!"
"...that is not reassuring!" Glynda snapped, trying to resist the urge to point her weapon at the portal, as it began bubbling...
...
The pool of azure light expanded, and the room was filled with a blue glow emanating from the emerging portal. Miriel slowly raised her tome.
"Gentlemen..." The older sage began, gesturing to the portal. "...it seems...we may have discovered a faster means of dimensional travel than the Outrealm Gate that we may deploy anywhere and anytime it is required."
The portal began flickering, a pool of darker azure welling from the center. Ricken could feel the hairs on the back of his neck rise in trepidation for whatever was on the other side of that portal...
These portals were linked to completely different places in the multiverse, places which were not normally linked to each other, being created by almost completely different methods. Allowing for normal circumstances, the two were not destined to link with each other.
Somewhere in the multiverse, however, something clicked. Everything went wrong.
The portals that were not meant to link to each other suddenly snapped to link towards each other.
This, of course, had its own consequences. That, in this case, coming in the case of a very powerful shockwave coming from the portals themselves, knocking the occupants of both rooms aside and filling the portal area with smoke. The shockwave could be felt for a mile around, having created a powerful tremor as a result.
It was a tremor that could be felt in both worlds.
Beacon Academy
Weiss calmly read a book, sighing to herself as she sipped a cup of hot chocolate. The cup itself had writing on it- crude, hasty writing in marker saying 'Number One Girlfriend'. It was a gift from Ruby, who had given it to her on a whim.
It was a terrible cup, but the heiress appreciated it all the same. It was the thought that counted, after all.
She smiled briefly as she read the text on the cup, sipping the drink within it, before-
"What the..." The heiress was suddenly shaken by a fierce tremor, shaking everything within RWBY dorm. Two books fell off their shelves, landing with a clap onto the desk below, and one hit Blake in the foot, waking the catgirl from her nap.
"Ow!" Blake cried out, staring at Weiss. "What do you want?"
"It wasn't me!" The heiress cried, shaking. "T-there's an earthquake!"
Ruby suddenly awoke, looking up. "Earthquake?!"
"Everything is shaking!" Weiss yelped. "Quickly, get down and get under something!"
Yang looked up, looking very concerned. "Crap! Everyone, get under something-"
Blake shook her head. "That's not an earthquake."
"Impossible! Then what made everything shake?!" Weiss inquired, panicking slightly. "Is this an antic of some sort?"
Yang shook her head to deny the accusation. "Ren said it was a day off for us today. No antics."
The reaper poked her head down from her bed. "Then what just happened? Why did everything shake? Weiss, are you alright?"
"...yes. I think I'm fine." The heiress sighed, regaining her composure, placing a hand on her chest. "What do you think that was?"
"An explosion." Blake explained, her ears twitching as she looked around in the air. "...I think I know where it could've come from, too; it came from the direction of the staff rooms."
Yang sprung from her bed, immediately grabbing Ember Celica and mounting her gauntlets, cocking them and swiftly replacing the Dust cartridges with fresh ones. "We'd better check it out. Even if it's just an experiment, an explosion over there that's not from an antic might not be a good thing."
Weiss nodded in agreement, looking to the brawler. "You have a point, Xiao Long. Let's check that out."
The heiress grabbed Myrtenaster- hanging in its scabbard from a hook behind the dorm door- and slotted it at her usual place on her waist, but not before slotting it out and reloading a fresh load of Dust cartridges into her rapier. Her other teammates grabbed their weapons from various hiding places.
Ruby frowned. "What do you think that could've been?"
Blake sighed, tapping her chin as she wrapped the ribbon of Gambol Shroud around her waist. "It's probably nothing, but...still, an explosion of that power is usually caused by a bomb of some sort, or by mecha. If there's an attack on Beacon, we should get there quickly and try to save the teachers."
"I hope it isn't an attack." Weiss stated, before Jaune popped into the dorm by opening the door, looking around.
"Did you guys feel that?" The knight inquired. "Was that an earthquake?"
The catgirl shook her head. "We think it was an explosion from the staff dorms. We were going to check it out. You coming with us?"
"Yeah." Jaune nodded, patting Crocea Mors at his side. "My team's checking on everyone else, seeing if anyone got hurt. They said I should go ahead and see what's going on."
Ruby smiled.
"It's settled. The five of us will head down to the staff dorms and see what's going on!"
Ylisstol Palace
Lucina was sparring in the training room with her daughter Morgan using training sabres. The Parallel Falchion hung from her waist, while a silver sword hung from Morgan's.
"Like I said, Morgan, you have to work on your footwork." Lucina cautioned her, calmly stepping back to allow Morgan to regain her composure. The tactician whined, pouting.
"Mother, you're far better at swordplay than I am, that's not fair!"
Lucina sighed, shaking her head. "You'll never get better if you don't watch yourself. Even if we're at peace, you still need to work on your-"
A tremor suddenly shook the palace, nearly sending the tactician stumbling and dropping her sabre. Lucina, the more practiced warrior, was able to maintain her balance, catching her daughter and hugging her to her chest.
"Gah! Thanks, Mother..." Morgan cried out, looking up at the princess. "What the...was that an earthquake?"
Lucina looked around, watching to see any signs of the building shattering from the pressure of the earthquake. "...no...no, if it's an earthquake, it's not a strong one."
Robin burst into the room, looking worried and breathing heavily. "Lucina! Morgan! What's going on?! Are you two okay?!"
The princess sighed in relief. "Thankfully. Do you know what's going on?"
"I haven't a clue." The grandmaster admitted, strolling over to hug his girlfriend and daughter. "I was thinking of going to find out what's going on, but thank Naga you two are alright."
Reflet and Todd poked their heads in, looking at the three hugging. Reflet frowned.
"Hey, I'd hate to interrupt the family reunion, but I think I know where the tremor came from." The grandmistress announced. Lucina looked over at her, curious.
"You do?"
"It came from the north." Todd added. Robin thought carefully; it didn't take long for realisation to hit.
"Miriel's house."
Reflet nodded in agreement. "Got it in one. I think Miriel did something stupid."
"...what could she have possibly done?" The princess inquired, confused. "What's going-you know, I don't really want to know. Let's just go and figure out what she did this time.
Robin, does anyone else know?"
"Chrom is checking on your mother now. I had Kellam go out to see if Cordelia and anyone else is fine." The grandmaster reassured her, before producing his Thoron tome. "Let's go. I'm afraid of what Miriel just did..."
Reflet patted her forged Brave Sword, Deus Xiphos, while Todd slung his Forseti tome into his robe.
"Just in case Miriel summoned demonic monsters beyond the veil. Y'know, like Cthulhu, Nyarlathothep...or Deadpool." Reflet explained, smiling brightly. "Let's go."
Beacon Academy
Weiss and the others finally arrived at the staff offices, where Cinder was standing around, her arms crossed. She gazed over at them, tilting her head.
"Ah. You five." The pyromancer stated, sounding relieved. "Well, I can trust you."
Weiss raised an eyebrow. "What happened?"
"Professor Faust did...something." Cinder explained. "I'm not sure what, and Ozpin told me to wait for Oobleck and Port to get back here so I can investigate.
You five are pretty competent, however. I should know, I taught you. So, can you five check what's going on and report back to me?"
Jaune was taken aback. "We're acting as scouts?!"
"Relax, Jaune. You're not going into enemy territory. If it's bad, you can fall right back." Cinder reassured him. "And you're my students, you're not exactly going to get jumped easily by a bunch of monsters.
Get back to me with what you can see, alright?"
Weiss closed her eyes, sighing. "So we're to be the vanguard into the room of possibly the most insane teacher in the school. Wonderful."
Ruby smiled. "Well, maybe it'll be fun."
"It's Professor Faust. At this point, I've learned to assume whatever she does is far more insane than the combined efforts of Blake and the Antic Order." The heiress remarked, before drawing Myrtenaster.
"Come on, let's figure out what's going on."
...
Miriel's House, Ylisstol
Lucina and the others gathered in front of the house. Reflet flinched, realising smoke was issuing from the door.
"There really was an explosion..." Reflet muttered, her grip on her sword tightening.
Lucina grasped the Parallel Falchion's hilt, drawing it. "What the-Miriel! Miriel! Is she alright?"
Robin pushed the door open, seeing the smoke trail issuing from a door that was somewhat ajar, leading to the basement.
"They're in the basement." The grandmaster stated, as Todd, Morgan and Reflet moved up behind him.
The princess slowly pushed inside, looking around carefully. "I don't like the look of this. We have to make sure Miriel and whoever else is in here's alright. Todd, you know how to use staves?"
"...yeah. Why, Morgan doesn't?"
The female tactician frowned. "I'm terrible with them. You have a spare?"
"I have a Heal staff. Does that count?"
Lucina nodded, moving up against the basement door. "Be ready to heal injuries."
Slowly, the princess pushed the door open.
...
Beacon Academy
Team RWBY and Jaune made their way into Professor Faust's office, opening it. Weiss was the first in, surveying the damage.
"What in the name of..." The heiress looked around, inhaling sharply.
On the floor was a destroyed circle of candle wax and Dust-knows-what else, with several half-melted candles smoking. On the wall to Weiss' right, she could see Professors Faust and Goodwitch, pulling themselves up from the floor. They both looked dazed, implying a strong impact onto the wall behind them.
What was most interesting, however, was the left wall, where a large, gaping hole had been blasted, smoke emanating from the massive gap.
Weiss' eyes darted towards the professors. "What happened?"
"Crap..." Jaune stepped in, surveying the damage himself. "This...it looks like a storm passed through here!"
"We...attempted to open communications...but it seems something went badly wrong." The witch explained. "...that portal...we don't know where it leads."
...
Miriel's House
"I am not sure where the portal leads." Miriel stated, staring intently at Lucina. The other four were busy surveying the large gaping hole in the wall, with Todd attending to Ricken and Laurent's rather minor scrapes.
Lucina sighed. "As expected, your experiments opened a portal to Naga-knows-where again. Robin?"
"I can't see a thing through that smoke." The grandmaster stated. "Whatever's in there, we should be ready to meet it when it comes out.
Reflet blinked, before raising a finger. "Oh...I think I know where this is going. I've seen this plot many a time before."
...
"...I think I know what might be going on here." Yang explained, holding a finger up. "Guys, guys. We might be...slightly overreacting."
Ruby and Weiss both had their weapons pointed at the portal- Weiss with her Myrtenaster, and Ruby with Crescent Rose in gun form, the scythe's blade planted firmly into the ground to support the recoil. Jaune and Blake had their weapons in their hands, ready to attack whatever came out.
Yang sighed, cocking Ember Celica. "...just...don't fire too early. I think this isn't a bad thing."
"I'd be inclined to trust you if it wasn't Professor Faust's doing." Weiss shot back, looking irritated. "Ruby, are you going to cover me? I'm going to hit whatever comes out of that portal."
"Aye, aye, captain!" The reaper responded affirmatively, before aiming Crescent Rose at the gap.
...
Lucina clasped the Parallel Falchion in her hands, staring directly at the portal. "Alright. Robin, Todd, cover me."
Reflet merely giggled. "Oh, hohohoh...this ought to be fun."
Robin stared at her, confused. "What do you mean?"
"Oh...nothing, nothing. Just get ready." The grandmistress waved him off."
Robin turned to the princess. "Lucina."
"Yes?"
"...be careful." The grandmaster warned. "We don't know what will come out of that portal."
"...understood. I'll be just fine, don't worry." She responded, smiling reassuringly at her boyfriend. "Just give me cover."
Robin opened his Thoron tome, a bolt of lightning sparking in his hand.
...
Weiss inhaled deeply, her gaze intent on the portal. A glyph spawned underneath her feet, and the heiress slid towards the portal.
...
Lucina hefted the sword in her hand, rolling her head on her neck. With a sudden yell, the princess ran towards the portal.
In an instant, the smoke cleared entirely, dissipated by the charge.
In the threshold between two worlds, Myrtenaster and Falchion met, rapier to longsword, blade to blade.
Lucina and Weiss' eyes met, their swords locked in struggle. The heiress' glyph managed to keep her stable against the superior strength of the princess, and she pushed back, staring intently at her.
That lasted for all of five seconds.
Lucina's eyes widened. Her opponent...was not who she had expected.
Weiss stared at her own in shock, holding her place.
The other four on either side stared at each other, confused. One thought was going through all their minds.
'What is going on here?'
To be continued...
A/N: So, our heroes finally meet, and the crossover begins in earnest. This ought to be an interesting one.
So, I hope you enjoyed that, leave your ideas, comments, suggestions, criticisms, reviews and thoughts, and I hope you have a GREAT day! Until next time!
