In the dormitories of Beacon Academy, a black-haired woman walked through the corridors to her room while talking with someone on her scroll "When I told you two to do some reconnaissance, I didn't mean that you two should go and flirt with the locals!" this woman was Cinder Fall, and she was furious, "I don't care if this was Mercury's idea, I need you two to keep a low profile, you should come to our room and quickly, there has been a change in the plans" Cinder said the last in a whisper in case someone were to be near and hear her said things that could complicate her mission.

She currently worked with who probably was the most dangerous 'person' in Remnant, Salem, if this plan failed she could very well be considerate death, first she needed to finish the Fall Maiden, retrieve the relic that was hidden in Beacon, and kill Ozpin if the opportunity presented.

"I don't care if you have to break his legs but bring him here," Cinder ordered to the person on the other side, after ending the call she sighed as she leaned against the wall "Ahh, I'm surrounded by idiots," whispering more to herself than anything. After the incident in mountain Glenn, the operation started to make some progress, the White Fang found a better place to hide in the forest outside of Vale, the robbery of Dusk was almost finished so Roman being arrested wouldn't be a problem and nobody suspect her or her team of being the mole.

But then strange things started to happen, Adam informed her that his men had been disappearing recently, it wouldn't be weird considering that Grimms prowled in the forest,but those disappearing always happened in the middle of the camp without anybody finding a body or traces of a fight, and now her reserves of Dusk were disappearing, someone was sabotaging her, but who?

Once she arrived at her room she closed the door and sat in a chair, trying to find who could be responsible "I don't think that Ozpin or his allies have found about our plan, and Neo wouldn't do something like this without the security that she could help Roman all by herself, Emerald and Mercury are too loyal to me so they wouldn't dare, Watts or Tyrian wouldn't dare to do something that could ruin Salem's plans, and Hazel has no reason to sabotage my plans". It wasn't until she suspired and saw her breath that she realized that her room was oddly cold.

"Who is there?!" She stood up fast and screamed, someone was in the room with her, she was certain that this person was also the one responsible for derailing her plans, it was too much of a coincidence for someone to infiltrate in her room and wait at the same time she decided to plan a countermeasure, "Come out so I can see the most recent pest in my life."

Looking around the room she spotted a large shadow in the door, it could be described jellyfish-like in shape but some kind of material covered it from 'head' to 'toe' in some kind of cloak that ended in numerous tendrils, the shadow was so big that it almost touched the roof in the room, it didn't have mouth nor eyes, it was almost like staring at shadow.

It didn't move nor made any sound yet Cinder just knew that it was observing her "Wh..what are you?" She started breathing more erratic and her heartbeat accelerated, she was scared, Cinder Fall was scared of wherever that shadow was.

Right now the most logical thing to do would have been to escape or avoid any conflict with the shadow, without the backup of Emerald and Mercury she didn't dare to attack it without knowing what was capable of. But that would mean admitting that she was scared, so Cinder conjured a spear made out of Dusk and she threw it to the Shadow, but the spear never made contact, it didn't move a foot before a tendril reached it midair stopping it, without thinking it twice Cinder jumped through the window in an attempt to escape from the Shadow, she needed to regroup with her team and find a way to stop the Shadow before it derailed her plans even more.

Cinder ran towards the entrance of Beacon, pushing anyone who was in her way, "Emerald said that she was in the commercial district, if I run fast enough I should be able to find them and come with a..." her thoughts were interrupted when a torrent of black particles passed around her, these particles started to gather to form the Shadow that was in her room just a moments ago, before she could fully stop, three tendrils shoot towards her, barely dodging them as they grazed her.

Students started to gather around her and the Shadow, "What is that?" "Should we call a teacher?" "Are they filming a movie?" "Is that a Grimm?! what is it doing inside of the school?!" the more students started talking the more alarmed they became, and soon enough they unsheathed their weapons "Take cover!" someone in the crowd screamed to Cinder and she instinctively jumped outside of the circle of students as they shot the Shadow.

But the Shadow didn't react no matter just how much the shot or how powerful the explosions were, it waited until everyone ran out of ammo that the Shadow attacked, first it attacked with its tendrils destroying the weapons of the students, when one tried to sneak behind the Shadow a tendril wrapped around his ankle, lifting him up and throwing him to the crowd, only to follow up with a whip from its tendrils, throwing away most of the students around it, breaking the Aura of some just through sheer force.

Without weapons some students decided to run, will others stayed to stop the Shadow, but the Shadow didn't pay them attention, one of its tendrils shot towards another group "Aaaaaaahhhh!" a scream surged from the crowd as the tendril retracted towards the shadow, dragging Cinder with it, the tendril having pierced her ankle and wrapped itself around her leg.

"Somebody stop that thing it's going to kill her!" "Why nobody has brought a teacher!" The students started screaming at each other without any idea of what to do, everyone was paralyzed from fear, a few students jumped behind the Shadow in a last attempt to stop it, only to be tossed with a tendril.

"Blake Now!" after this scream a blonde girl was catapulted towards the Shadow, punching it in the 'face', while another black haired girl with a bow cut the tendril at the same time the punch connected, liberating Cinder and throwing the Shadow towards the nearest wall.

"Are you ok? let me help you get out of here" The girl with the bow asked Cinder, helping her get up.

"As good as anyone would be after being attacked by some strange Grimm" Responded Cinder sarcastically, barely keeping herself from blowing the persona of Cinder, the kind and cool student from Mistral.

As Cinder was leaning from the girl's shoulder she looked towards the Shadow now stuck in the wall, "Something isn't right" she said trying to find what was wrong, she continued to stare the Shadow.

"See I told you that it would be easy Blake" The same blonde girl who punched the Shadow approached Cinder, or more specifically to Blake, the girl that was helping her.

"It's a good thing that it worked, but I think that you should leave the strategies to Ruby and Weiss" Blake responded with a calm smile, "We better take her to the infirmary and tell Ozpin what happened here".

It wasn't until Blake started walking towards the infirmary that Cinder realized what was wrong, "Wait, that thing isn't dead yet, its body hasn't disappeared yet!" Cinder screamed.

Yang looked at Cinder in confusion, "What do you mean that it hasn't disappeared ye..." The blonde girl didn't finish before a black tendril hit her in the back, throwing her away from Cinder and Blake

"YANG!" Blake screamed alarmed from the surprise attack, only to dodge a second attack going towards her and Cinder, "Hide in those bushes over there, try calling anyone to come here with your scroll" Blake said in a stern tone while she left Cinder on her own.

Blake ran towards the Shadow, dodging Tendrils that were shot towards her, leaving some shadows on her own to try to confuse her attacker, once she was a few meters away from the Shadow she transformed her Sword in a gun and started to shot it while running in circles around the Shadow. The Shadow was so concentrated on Blake that it never saw Yang come from behind it, realizing too late when the blonde punched it's 'torso' lifting it a little bit from the floor, only to continue with another punch that returned the Shadow to the ground, leaving a crater. After a few seconds, the Shadow got up again and started to whips its tendrils towards Yang, those attacks were to fast that Yang decided to block with her forearms the attacks.

The Shadow didn't look that it would stop at any time and Yang feel how she was almost charged, now she needed an opportunity, it was when her hair started to look like it was set on fire and her lilac eyes turned red that Blake came from behind the Shadow, slicing it in half, being that moment when Yang broke her guard and punched a hole in the upper half of the Shadow, leaving both halves lifeless in the ground.

"Well, that was a thing." Yang said with a tired smile, "By the way, were where you while that thing started whipping me?" she continued now locking curios for the answer from her partner

"I was trying to find its weak point, and besides, it wasn't like you were in trouble" Blake responded with a serious face but a playful tone.

"Oh really, so what was its weak point?" responded Yang with an amused expression.

"I didn't find any, so I did the second-best thing and hoped that you would finish it with brute strength alone" Blake responded now looking the disintegrating body of the Shadow, her relaxed expression disappeared, being replaced for one of terror when she saw how the black particles of the Shadow started to gather, reforming its body

"Eeeh, Blake? I don't think that your plan worked" Yang said as she and Blake took a step back.

The Shadow finished regenerating before the two huntresses, but it looked a bit different, now with some red marks all over its body an with two thin human-like arms emerging from its sides, after closing its fingers like it was familiarising with its new appendage, it took a step forward, Yang and Blake took instinctively a step backwards, the Shadow tilting its head at the reacting, then extending its new arm, pointing a finger at the direction Cinder, who was being carried away by a girl with green short hair.

"Blake, I think it wants us to give that girl to it" Yang whispered to Blake.

" I can see that, do you think you could defeat it again for long enough so we can escape?" Blake asked, never leaving the Shadow from her vision.

"That won't be necessary the cavalry it's on its way" Yang responded with a smug grin, putting something in her pocket.

The Shadow now seeing that neither of the huntresses would do anything it took another step, only for a white glyph to appear in the ground, freezing it in its place, shortly after a girl with white hair ran towards Blake and Yang.

"Sorry for keeping you waiting, Ruby when looking for professor Ozpin, she should be here at any moment" The white-haired girl responded now trying to catch her breath, "So that's the new Grimm that you said infiltrated Beacon? How it even got here without anyone noticing it?" She continued, now giving a good look at the Shadow who now was trying to break free, it wasn't until the Shadow saw who was the new girl that it stopped struggling, now 'staring' the new girl without making any move.

"Well, it looks like everything is under control now, thanks, Weiss" Yang said, releasing her breath that she started holding without noticing, "We better keep an eye on that Grimm, who knows what other tricks it has under its sleeves, or at least until Ozpin arrives" Yang continued now relaxing that the fight was over, now looking to her surroundings, now deserted from students, even Cinder wasn't around anymore, having escaped .

"Guys are you ok?!" A chirpy voice screamed from ahead of them, it belonged to a girl with a red cape and black hair with red tips, she was accompanied by a tall man with gray hair with a cane in hand, both of them running towards the rest.

When the girl with the cape screamed the Shadow broke free from its trance-like state, turning its 'head' around to see the girl.

Weiss, Blake, and Yang held their breath at the sudden reaction from the Shadow, making both the girl with the cape and the man with the cane stop, now everyone paying attention to the Shadow.

"AaaaaaAaAaAaaAAAAAAAAAaaaaaahhhhhhhhhh!" at the sudden scream from the Shadow everyone covered their ears, 'rrRuu..bbyYy Rooooooseee!" after the second scream the Shadow grew two blades in its forearms, only to disappear in a cluster of black particles, and for this particles to move behind the girl with the cape, reforming in the Shadow in less than a second, now with a blade moving towards her neck.

"Ruby watch out!" screamed Yang in panic, now running towards Ruby, only for a glyph to appear below her and propelling her.
