A/N: This will be a femHarry/Tony stark fanfiction, one of my favourite pairings .

I don't plan to have a long story ,but I'll try to stay true to Tony Stark's journey. I will change the end bacause I DO Hate Tony's fate in Endgame!

This story was slightly inspired by 'The Almost Forgotten Marriage Contract of 176' by worldtravellingfly .

Finally, I do not own HP or Avengers characters.

Chapter 1 : Hello Mr Stark , I am a witch

Helena couldn't believe her ears, maybe this was another nightmare. Surely fate couldn't be this cruel !

She worked so hard towards her freedom, she shed her blood, her tears, her magic to break her shackles; shackles made by Dumbeldore, by all the bigoted pureblods and the irrational light followers.

And now she had to endure this injustice, this blasphemy because she was Helena Potter, A POTTER !

Her name was the only thing that connected her to her parents. It was the last link between the orphan young woman and her family . But now this name, became, like everything else in her life, a curse, another chain around her neck.

''Heiress Potter ?'' Ragnok's voice cut her internal monologue.

'' Yes . ''

'' Here is the contract, you said that you wanted to have a look. But I can assure you that it's ironclad. Afterall, It was made by a Peverell. Nothing in this world is mightier than a Peverell's magic.''

If it wasn't for the gravity of her situation , she would have laughed. A goblin praising a wand wielder ! What had become of this world ?

''I trust your judgement. But… I just feel like I owe it to myself to try one last time. ''

'' Of course. It's your right after all, but you have to be aware of the deadline: Three days'' . The Potters' goblin's voice was final.

It made her skin cringe, she wanted to run away , as far as possible , from this wretched place. Could she, perhaps, use a time turner ? A day's worth of time travel would be worth all the gold in her vaults.

''Then I guess we will meet again in three days''.

Just as she stood up and prepared to leave, Ragnok's voice, once again, rang out in the spacious office.

''One last thing heiress Potter, you should be aware that we have to send a copy of the contract the the other party. ''

Oh Hell ! Could this day get gloomier ?!

''Do you have to ? '' Helena whispered softly.

''Yes . It's one of the conditions, both parties must be aware as soon as you reach your 18th birthday. We did you a favor by choosing to inform you first . ''

Rangnok's voice was sarcastic, but she didn't have the energy to discern his features. '' The goblins' nation is in your debt for saving the wizarding world from the dark monster, and goblins always pay their debts.''

''Oh I know, don't mention it ''. Helena murmured before heading for the door as fast as her long legs could carry her, she couldn't wait to leave the confines of this twice cursed room.

Tony was thinking about taking a break and maybe calling some friends and …..well getting laid. He deserved it, after all he just finished building his suit's prototype. Hell ! Being a genius was awesome.

He stood from his chair and left this workshop.

Noticing that it was already daytime he went straight to the terrace , maybe some vitamin D first thing in the morning would do him some good.

But, as soon as he opened the front door, the craziest thing ever happened !

An owl, A real damn two winged owl was flying straight towards him.

His hackles were raised , after all The great Tony Stark couldn't be harmed by a stupid brown menace, it would be scandalous if this news reached the tabloids, there wasn't even a hot model in the mix !

After his surprise wore off, he really concentrated on the flying chicken, it was carrying a... file ? Oh man ! Was this some sick joke ? even his brilliant mind didn't come by something so extreme.

The owl seemed to get bored by his inspection, so it just threw the damn thing and escaped before he could as much as blink.

Running his hands through his hair, He thought about his next step. Should he touch the thing ?

Remembering that his best friend was just a call away , He screamed '' JARVIS !''

-Three days later-

Pepper massaged her temples for the millionth time : '' Tony you have to get ready, the crew is waiting ''.

Then slowly, because she was hurting too, and she knew the magnitude of this mess : '' I know this is so sudden, and we don't know anything about what awaits us in the other half of the world, but the least you can do is meet this girl, woman …..I don't know ! But we have to meet those people. ''

''Pepper ! You can't be serious ! I thought you was the voice of reason but now you want me to go ahead with this masquerade ?'' He snapped. '' I couldn't even find a damn thing about this cult ! I don't know what we will be facing ! And even if they turned out to be decent people, I DO NOT WANT TO GET MARRIED !''.

Pepper sighed, this was going to be a long long day, and they hadn't even touched the britsh soil yet !

Helena felt like pulling her hair out ! But she couldn't. The atmosphere in the room was gloomy enough . Andromeda's face was stoic, her mask in place.

Hermione was bitting her nails , and by the look of it, there wouldn't be much left till the meeting starts . Ron was as pale as a ghost, and for the first time since she met him 7 years ago he wasn't hungry, even though they spent 2 hours already waiting for their guests.

How bad could it be? surely they would reach a compromise .

But the heir…..No, she wouldn't think about it yet ! Baby steps , yes baby steps.

The doors suddenly opened , and Bill weasley came through follwed by a tall, lean blonde wearing a suit. Was she his lawyer ? or maybe his fianc….No ! baby steps ! She had to ask first, no assumptions.

Finally, she saw him.

He was tall, maybe 6ft3 to her 5 ft 10, with a lean, strong frame. His brown silky hair was well styled. His rich dark eyes were guarded and definitely the most fascinating feature about him. There was something familiar about them .

Tony Stark was absolutely gorgeous .

''So, now what ?''. His accent was clearly american. Merlin! she underestimated the charm factor there.

Tony studied the people present in the room. Yeah ! The room !

If he hadn't touched the damn things with his bare hands and almost got slayed- if not for Fang's intervention( or was it Bill ?)- he wouldn't believe that he was in an honest to God wizarding bank ! Man ! His hands just itched to start his research on this new world ! A whole hidden world ! It made everything he knew look silly. And for the first time in his life he felt stupid, small and meaningless.

There was 4 people in the room, or maybe 5 if you took the goblin into consideration.

First , he met the stony gaze of the old lady. Her stormy grey eyes burned him and her message was clear : '' Don't mess this thing, whatever it is ''.

Then there was the guy , you had to be blind not to notice the fiery red hair , he snorted , there were just so much readheads in his future .

And finally the girls.

One of them was looking nervous, she had brown hair and brown eyes, she was pretty but nothing was special about her looks.

Then…. He he locked his eyes with the most exotic emeralds he had ever seen . Her eyes were beautiful in a way he couldn't explain. The windows to her soul...

This girl was a fighter, he could tell by the way she carried herself. She was tall and athletic, towering over the other 2 women even while sitting. She had messy long black hair that fell freely on her shoulders . His fingers itched to run through the wild strands.

He could honestly say that she was the most beautiful woman he had ever seen.

When their eyes met she didn't blink , nor did she seem impressed by his looks like others usually do. She kept her calm and waited for him to take the first step.

Yes. This girl was Helena Potter, his intended, he coudn't be wrong.

''So, now what ? ''
