Wohoo look who's back. ME. And I brought you another Avenger x HP crossover fic. But this time it's a BIG AU! I know, I know I should update Love the Pain Away. I'm trying (really) but I got a bad case of writer's block for the next chapter. And I need a little bit more time to flush the block away and iron out the next chapter. So while you wait for LTPA, here's a new story from me. I hope you all like this.

Warning (s): Massive AU! Deviates from both MCU and HP universe

Relentless: Prologue Chapter

AT 17 YEARS old, I never expected for my life to be cut short. Make no mistake, I've always known that I'm not going to have a long life. Especially with what kind of life I was living at the moment. But all my life, I've always dreamed of a normal life for myself. It was a wishful thinking but I still dreamt about it. A normal family, friends, attend a good school, get a decent and good paying job and settle down- all of that. A NORMAL life. But like what they always say; you can't have everything—especially if Fate is a bitch and you're me.

I lost my parents at the tender age of one, got stuck with my horrible relatives and slave away my childhood catering to their whims. So, no normal family. When I reached my eleventh year of existence, I received this letter saying that I'm supposed to attend this school of magic. Turns out, I'm a witch. At that point of my life I realized that I'm not getting that normal life that I wanted. There's nothing normal with my life or my name is not Briar Rosabelle Potter.

And just when I thought that I can have a not so normal life within this secret society of magic as a witch, I found out that I'm famous and a psychopath and his followers are out to get me. Who was not really dead after his stunt with one year old me. And now I'm expected to defeat him once again and save the wizarding world who are fickle as heck. One day I'm their saviour and the next I'm the next Dark Lady. Oh well that's my life in a nutshell.

And now it all leads down to this. Here I am staring at the brilliant night skies, my back laid on the stone cold pavement. I've never felt more at peace. Given that I literally can't feel anything but I'm at peace. No more burning pain, misery and finally the war is over. I blinked my eyes as I focused on the twinkling stars above that reminded me of my former headmaster's eyes as the desperate voices of my friends called out my name echoed in my ears. It's funny how the same spell that I survived from is the same spell that inevitably cut my life short. Yes, I know I'm dying I was hit my an Avada Kedavra though I'm not sure who casted it. What I'm sure is that Voldemort is in the same state as I am. What I'm midly confused about is why I'm still somewhat coherent. Avada Kedavra delivers a quick death and I'm still on the process of dying. Hmm…

Finally I felt myself drew a deep shuddering breath—my last one. One more look at the once majestic castle—Hogwarts that I will always call 'home', one last look at the people who I consider my family. And I closed my eyes, I welcomed the inevitable.

…

…

…

"Not so fast, Briar Rosabelle Potter."

My eyes snapped open and my body bolted upright at the rasping voice above my head.

I turned around only to see a familiar interior of King's Cross Station, the same station that I've visited not too long ago. "I'm still not dead?" I asked myself, confused at my predicament. I stood up from the white floor and wandered around. There's nothing different from my last visit, the train is still there and the bench where Dumbledore and I sat on is still there.

'What's happening?'

Then I heard the voice again.

"Oh you're very much dead, Mistress…"

I turned around again and saw a woman—a gorgeous woman dressed in a fine dress of black and emerald.

"W-What do you mean by Mistress?" I asked warily. A whole year of playing cat and mouse with a homicidal dark lord did nothing for my overwhelming paranoia.

The woman smiled eerily as she glides closer to me. By instinct, I tried to move away but found myself stuck in my place. The woman raised her arm revealing a skeletal hand and ran it softly down to the side of my face. I resisted the urge to cringe.

"Briar Rosabelle Potter, descendant of dear Ignotus Peverell, the only mortal who managed to gather Death's three mythical artifact and bring them together." She crooned, she pats my cheek gently. "The moment you held all the Hallows together, you, Briar Rose have rightfully gained the title as the Mistress of Death."

My eyes widened in disbelief. "Then that means…you're Death?"

The woman smiled once again, but this time it was more human like than the previous ones. "I am Hela Lokisdottir, goddess of Death, ruler of Nieffleheim, personification of Death itself whatever you mortals like to call me at you service…Mistress."

…

It took me a little while to comprehend what Hela has just revealed, it's not every day you die and meet Death face to face and then have the title of Master of Death thrown in your face. That's something I could die without, thank you very much.

"So… What's going to happen to me now? I'm dead, you said so yourself."

"And that's a reality that I never intended to happen."

"Huh?"

Death let go of my hand and glided again around the station. "You are not meant to die today Briar Rose. You still have a long life ahead of you. A bright future. And yet Fate deemed it otherwise and exploited you momentary vulnerability-."

I blinked. I have no idea what Hela was talking about. Fate? Vulnerability? "Uhm…"

"—And your death is something that I cannot allow…So I made a deal with Fate." She continued and again I found myself unable to move. I suddenly got this bad feeling tugging at my gut.

"What do you mean deal? I don't understand."

Death flashed me a mysterious smirk and leaned closer to me. "You don't have to. You won't even remember much about your previous life anyway."

"WHAT?"

"You will be reborn into another world. A world similar yet different from this." Her skeletal hands gestured around and she leveled me with a deep soul searching gaze. I was caught of guard when Death suddenly pushed me and everything turned into darkness.

Before I was engulfed by darkness I heard Hela whisper. "I'll see you soon Mistress… Good Luck."

From the darkness that surrounded me, different colors suddenly exploded while I fell through what I felt like was an endless abyss. Stars and cosmic entities assaulted my eyes as I felt everything that defined me as… as… What was my name again? And I knew no more.

…

"How is she doctor? What's causing all these symptoms?" A haggard looking Howard Stark demanded the moment his family doctor exited their room.

The doctor stared at Howard for a moment answering. "Maria is going to be alright Mr. Stark, no need to be alarmed."

"But her nausea and everything. Tell me what is wrong Doctor or I swear—"

"Fatigue and Nausea is a common symptom for all expecting mothers Mr. Stark."

"So what does that mean—wait, what did you just say?" Howard babbled, his eyes widening at what the doctor just said.

Th doctor flashed the man with a bright smile. "Congratulations Mr. Stark you're going to have another baby."

So... What do you guys think? Should I continue? I will probably. I need to get this idea out of my mind. But do tell me what you think about my prologue chapter.

I apologize for any mistakes and grammatical errors. I don't have any beta and I think I don't want to have one to be honest. I always try by best to proofread and edit my stories all I can. Hopefully there's not too much mistakes that I've missed. T

Anyway Thanks for reading! If I get a good response for this chapter I'll post the next one soon.
