A/n: So, I was real bummed that Shadowhunters ended… but then I remembered the story is never really over so long as we have fanfics! So uh here ya go

This takes place right after they defeated Valentine so no Johnathan or Lilith in this story

Disclaimer: If I owned Shadowhunters it NEVER WOULD'VE ENDED

Chapter 1

-Alec's Pov.-

I sigh, throwing the report down on the desk. It didn't make sense, the attacks just didn't make sense.

There'd been multiple reports of mundanes getting bit this week. That wasn't all though, every victim bit soon became seriously ill and in a few short days either they went mad after surviving the sickness or died.

I groan, rubbing my temples none of this makes sense. These attacks aren't like anything recorded in the archives… so what could this possibly be?

-Jace's Pov.-

Me and Izzy are on patrol, until we discover what's behind these attacks the institute is going to be slammed with work.

I sigh, sensing Alec's stress. "He needs a break," the words leave my mouth before I even realized I said them.

"We all do," Izzy added, playing with the stele in her hands. "But Alec has been pushing himself more than usual, he really needs some rest."

"If only it were that simple, we'd just defeated Valentine and now-" I'm cut off by a scream, judging by the sound, it sounded like it came from a few buildings down.

Me and Izzy rush towards the source of the scream, turning down the alley to see a woman collapsed in the middle of the alley.

We run to check on her, seeing a bite similar to the previous reports.

"Are you ok? Can you stand?" Izzy's question caused the woman to nod, getting to her feet.

"Do you need any help? We can take you to the hospital if you'd like," my response only earns a weak laugh from her.

"Oh, no. No hospitals please, too many windows." As she speaks I notice her fangs, telling me she's a vampire.

"You're a downworlder," Izzy says, stating the obvious. "In that case, come with us to the institute, we'll get you patched up there. We'd also like to ask a few questions if that's alright."

The vampire happily agrees, and the three of us head back to the institute.

-Alec's Pov.-

My phone rings. I look at the screen, seeing Magnus' name before I answer it.

"Ah, Alexander! You answered!" Magnus' bubbly voice rings through the phone speaker and I can't help but smile.

"Yes Magnus, what's up?" I lean back in my chair, thankful for the quick break Magnus has provided me with.

"I was just wondering when you'd be home? I have a surprise in mind and I just can't wait to show you!" Magnus' excitement is evident in his voice, making me relax for the first time in days.

"Well, it's been busy over here but I should be able to finish soon."

Just then, the door opens, revealing Clary. "Alec a Downworlder's been attacked."

I don't react at first, only staring at her in shock. Why suddenly was a Downworlder attacked? Up to this point it had only been targeting mundanes.

"Alec? Sweetie?" Magnus sounds worried, he'd must've been trying to get my attention for awhile. "Everything alright?"

"What?" I ask, not fully understanding what he'd said. "No- I-I mean yes! I mean… I'm sorry I gotta go." I quickly hang up, not giving him the chance to say goodbye.

My stress suddenly resurfaces tenfold as I get up from my seat and out my office to see Izzy and Jace questioning a woman as another Shadowhunter treats her wound.

I let out a tired sigh, walking up to the group. "I can take it from here if you two want," my voice was laced with exhaustion, I only now realize how tired I really feel.

Izzy turns to look at me, "by the angel," her tone causes Jace to turn towards me as well, concern growing in his eyes.

"Alec, you look awful," Jace's comment almost makes me laugh, no shit.

"You should take the rest of the day off," Izzy begins, smiling warmly. "You've been working so hard the past week, we can take it from here."

I smile, the idea of spending the rest of my night with Magnus sounds enjoyable, but I'm the head of the Institute. "I couldn't possibly, I'm the head of the Institute."

"Just go, we've got this," Jace gives me a reassuring smile, letting me know I can trust them to get things done.

I'm about to answer when my phone rings, I look at the screen to see Magnus' name once again. I look up to see Jace look at me questioningly, causing me to sigh, "it's Magnus, I should take this."

I answer the phone, almost instantly hearing Magnus' worried voice. "Alexander, is everything ok? You seemed distraught."

I let out a sigh, rubbing my face, "yeah Mags, I'm fine."

"That's a lie!" Jace yells, making sure Magnus heard him.

I cover the microphone with my hand before whispering, "Jace! Quiet!"

"What's wrong?" Magnus worry carries through to his voice.

"Nothing, it's just a Downworlder's now been attacked, whatever this thing is it isn't just targeting mundanes."

"That makes things more complicated, doesn't it?" Magnus' question causes me to chuckle.

"Yeah, no kidding." I pause, glancing at Jace who nods in response. "But I can worry about that in the morning. I'm on my way over."

"Really?" Magnus sounds as if he's teeming with excitement, "well I cannot wait! I'm so glad you're getting a break!"

"Yeah, me too." After that, me and Magnus say goodbye before I hang up, directing my attention towards Jace and Izzy. "Thanks you guys."

"It's nothing! You deserve a break! Now go, and be safe." And with Izzy's words I rush out of the Institute, eager to go see Magnus.

I walk through New York's crowded streets, enjoying the feeling of the nice, cool air after being locked up in the stuffy atmosphere I've been in for days.

It's only when the street begins to become deserted do I feel a little uneasy, there's some sort of demon on the loose, I need to be on guard.

A few minutes pass, and I hear a sudden noise come from the alleyway to my right, causing me to jump out of my skin. "Hello? Anyone there?"

No answer. I grab my Seraph blade before going to further investigate the source of the noise.

The further I go into the alley, the more nervous I get, what if this is the demon that's been the cause of these attacks? What if I get bit?

After a few minutes of searching I find nothing, causing me to let out a breath of relief.

I put my blade away before turning around, about to head back to the street when, "not so fast… Mr. Lightwood."

I quickly whip back around, just in time to see a woman sink her teeth into my shoulder.

My eyes go wide, my entire body feels like it's on fire. I want to scream, but for some reason I can't make a sound, I can't breathe.

I crumple to my knees, refusing to fall, I will fight.

"Oh my, who knew Shadowhunters would taste so good?" The woman lets out a bone-chilling laugh before continuing, "ah, Lightwood, you seem like you'll be the most promising one yet… I think I'll hold onto you." She leans down, grabbing my arm.

I desperately try and pull away, but it's useless, I'm too tired.

"Do you mind if I have another taste?" She bites down on my wrist, and the pain increases tenfold.

I want to pull away from her grip, to scream, to cry, to do something but… all I can do is sit there and watch her teeth tear into my skin as I burn alive.

My body goes limp, I'm barely holding on to consciousness. A tear slides down my face as I think of Magnus, he'll be so worried when I don't show up. And after a few moments, my eyes flutter closed.

-Jace's Pov.-

We've just finished up with the questions, when suddenly the vampire, who's name I discovered is Samantha, doubles over, grabbing the wound she just got.

"Everything ok?" Izzy says, sounding genuinely panicked.

Samantha doesn't answer however, only letting out a shriek before turning to dust.

My eyes go wide, "What the hell?"

"What happened?" Izzy's question hangs in the air for a minute before she continues, "Did the bite do that?"

I look at her, "what else could it have been?"

"Should we call Alec?" Izzy asks, her brow furrowed in concern, most likely not wanting to disrupt Alec after we just told him to take a break.

"Yeah, we should call him, just to let him know." I pull out my phone, about to call his number. "He doesn't have to worry about it till the morning but he should-" I stop mid sentence, my Parabatai rune burning.

I suck in a sharp breath, grabbing my rune, something's wrong.

"Jace? What is it?" Izzy puts her arm on my shoulder.

"My rune," I choke out, barely able to breathe. "It burns." I take deep breaths till the pain subsides, letting out a breath of relief when it does.

The relief is short lived, however, panic quickly surfacing. "Alec," I breathe out before fumbling with my phone for a moment before pressing the call icon on Alec's contact.

The phone rings before going to voicemail. I quickly hang up, "Damnit, I'm gonna try Magnus."

I quickly switch to Magnus' contact, praying he picks up. Please be ok.

-Magnus' Pov.-

I wave my arms, a round table appearing. The table has a white table cloth, with a small Eiffel Tower as the centerpiece.

I smile, proud of my work, he'll love this. I continue decorating making the outdoor setting look just like a Paris scene. Alec doesn't always like big crazy gestures, he much more enjoys simple, thoughtful ones.

I take a step back, thinking about what else I could do, when my phone goes off. I look at the screen to see an unknown number. Odd.

I decided to answer, "hello?"

"Magnus!" Jace yells, starling me quite a bit.

"Jace, no need to yell, what seems to be the problem?" I try to keep my composure, but the urgency in Jace's voice makes me nervous.

"Is Alec there with you?!"

"No, he's not here yet… why is something wrong?" There's a hint of panic in my voice, if Jace called this panicked asking about Alec…

"I think Alec's in danger."
