Mauder's Green Lily

By: kpron2008

Harriet Jasmine Selene Potter had moved to New York about two years ago after the Second Magical War and there were only a selected few that she had kept in contact with back home in England.

However, during her time here; she managed to open her beloved Café called Mauder's Green Lily to honor her father, her mother, and her godfather as well as her honorary uncle but the treacherous rat was not included. She had to admit that it was a calming except when the Avengers were involved especially Tony Stark a.k.a. Iron Man who was now her husband because he had been drunk at the time and she had tried to reason with him.

Tony had surprised her with the new and approved Mauder's Green Lily Café as a wedding gift because he knew how much it meant to her.

Harriet was lost in thought until she heard some familiar voices in the café and came out of her office.

"Grandma, what makes you think that Aunt Harriet is here?"

"Teddy, I would know Harriet Potter anywhere and so would your cousin, Draco and his mother. "

"It's true." Harriet heard a male voice drawled.

"Draco, you have to admit that there must've been a reason that Harriet didn't contact any of us." A feminine voice said.

"Look! There's pictures!" Teddy said pointing.

"These are pictures of who Lady Stark considers family and friends." A disembodied voice said.

"What the Salazar?!" Draco said.

Suddenly, they heard someone giggle and turned to see a young woman standing there then they heard her say, "Jarvis, contact Tony and him his in-laws decided to pay a visit. And that he has thirty minutes."

"Contacting him now, Lady Stark." Jarvis answered.

"Harriet?" Andromda said.

Mrs. Stark nodded.

"Who's Tony?" Teddy questioned.

Harriet smiled and said, "By marry me, Tony Stark also known as Iron Man became your Godfather."

Teddy turned towards the woman and with wide eyes then said, "Aunt Harriet?!"

"Hello, cub." Harriet said.

Teddy ran and hugged her.

"You married a muggle?" Draco questioned.

Harriet looked at Draco and said, "Yes and he happens to be a billionaire turned hero. Plus, the American Wizarding World is a little bit different from the British Wizarding World and Tony has helped them use muggle technology with around magic. Not to mention, they came to the aid of muggles when Loki the Nors God of Mischief and Lies decided to attack." Harriet stated.

Narcissa and Andromeda were shocked.

"Cool!" Teddy said.

"Harriet, I want to know about Sirius's son-in-law considering you were his goddaughter and is his daughter through blood adoption." Narcissa stated.

So, Harriet nodded and began telling the story of how she met Tony and when they married.

Meanwhile, at Stark Tower...

Tony was talking with Bruce, Clint, Steve and Thor when Jarvis said, "Sir?"

"What is it, Jarvis ?" Tony said.

"Mrs. Stark wishes for me to inform you that your in-laws have arrived and that you have thirty minutes to get to the Mauder's Green Lily. " Jarvis stated.

Tony paled and rushed up to their room and immediately freshened up then came downstairs then made his way to the loft.

Steve and the others watched at how fast Tony had moved due to the time limit.

"I've never seen Tony move so fast." Clint said.

"Man of Iron seemed to have pale when a time limit was mentioned." Thor said.

"Jarvis?" Steve said.

"Yes, Steve?" Jarvis said.

"Why was Tony pale?" Steve questioned.

"This will be the first time that Mr. Stark will face his wife's magical relatives from Britain and seek their approval." Jarvis answered.

"In other words, Tony is nervous?" Clint said.

"Mr. Stark is indeed nervous because he married the Heiress of a noble house in Britain." Jarvis said.

Steve spewed his drink as did Thor.

"What is that for?" Bruce asked.

"Man of Iron is no longer Man of Iron but Lord Man of Iron." Thor said.

"Huh?" Bruce said.

Clint was curious as well at what Thor meant.

"It means that Tony is a member of the Royal Court of England." Steve said.

"WHAT?!" Bruce and Clint shouted.

Just then, Natasha walked in with Nick Fury and asked, "Why was Tony in a hurry?"

"He's meeting his in-laws and his wife gave him thirty minutes." Steve said.

Natasha whistles.

"Now, why would she do that?" Fury questioned.

"Because it's customary to meet the family; however, you do remember that Tony married Selene while he was drunk?" Steve said.

Clint, Bruce, Natasha, and Fury nodded.

"Well, Steve and I believe that Man of Iron had no idea that he married a member of the Royal Court of England and now he has to prove his worth to Lady Selene's family." Thor stated.

Fury didn't know what to say to this until he recalled some people showing respect to both Selene and Tony before and after the attack made by Loki; then said, "Why didn't Stark say anything?!"

"Master Stark was still processing what Lady Selene had told him." Jarvis answered suddenly.

Meanwhile at Mauder's Green Lily...

Tony entered and said, "Love, I am sorry for being a little late."

Harriet turned to see that Tony had gifts for her family members.

Tony noticed Selene's look on her face and said, "I got some gifts for your family as well as some of your friends who couldn't be here that I went ahead and sent them."

Harriet smiled.

Draco cleared his throat and said, "Thank you for the gifts, Lord Stark and I am Sirius would approve of your marriage to his goddaughter/daughter. However, we are here to prove your worthiness to her before we give our blessing with our family magic."

Tony was beginning to understand what Selene meant when she had explained everything to him about the British Wizarding World nobility and everything about magic.

"We also plan to test you, Tony Stark of your worthiness as well as your political skills because should you and Harriet come into the British Wizarding World; you will have to play the part of a Noble Lord." Andromeda said.

Teddy opened his gift from Tony while the adults were talking.

"Grandma! Look, what Uncle Tony got me!" Teddy said holding up his gift.

Andromeda looked to see that Teddy was holding action figures and smiled.

"May I ask what those tests might be?" Tony asked.

"The tests will see if you are completely capable of holding the Lord Titles since Harriet holds the Lady Titles that she has inherited. "Draco said.

"Okay, so when do I start the tests?" Tony questioned.

"Now!" Draco said.

Draco immediately casted a spell and the café changed.

Tony found himself found himself in a forest. He wondered if this was the first test, but he also wondered if it was a knowledge test or a political test or even a test to test his skills.
