May 2013, Harry's Bastion, Godrick's Hollow

Natasha woke up and turned her head to the side. The other side of the bed looked slept in but empty. Her hand ran over the sheets feeling the warmth that was slowly fading. Smiling, she stood from the bed and grabbed her robe from the back of a chair and wrapped herself up. Leaving the room she turned towards the staircase and saw that the sun was barely on the horizon through the large window. Moving downstairs she examined the house that she had been living in more often than her own place, the walls were decorated with moving paintings and tapestries. Some were older than most countries, most depicted long forgotten families or battles, others were legends of creatures and gods. Getting to the bottom of the stairs she turned towards the kitchen where she heard the other occupants of the house. Walking through the doorway she found Harry making a big show of cooking as he told of his adventures with his friends. Wanda and Pietro were both sitting at the island, already eating, listening to Harry with rapt attention. Harry's eyes swept over to her when he noticed her walking in and gave her a soft smile before he continued his story.

"That's when Fred and George both got caught." Harry shook his head as he plated another omelet, "They should have known better than to bargain with Peeves." Harry chuckled.

"What was their punishment?" Pietro asked.

"Well they had to reupholster the carriages, because they couldn't magic away the smell." Harry said with a grin as he turned to Natasha and greeted her with a kiss. "How are you this morning?"

"Perfect. This mine?" Natasha asked as she picked up a plate. Harry nodded so she took it and sat across from Wanda. "How are you two this morning?"

"Good. I've been studying for the end of the year exams. Dad told me that if my grades were good enough he would teach me to make a golem this summer." Wanda said with a big smile on her face. Natasha smiled at the girl's happiness. She also loved to see Harry's face light up every time the twins called him dad. It made her happy, but at the same time it sent a spike of guilt to her gut knowing she couldn't give him that.

"That's right. With that comes some light elemental magic and advanced charms." Harry explained as he finally took a seat and started eating. From there Harry quizzed them both on what they were learning and how school was going overall.

"Aren't you going to ask us about history?" Pietro asked as he finished the last bite of his third omelet.

"I don't think my understanding of history would help you." Harry said with a chuckle. "I'm still learning the history of this world myself after all." Wanda and Pietro both nodded. Harry finished up his food and stood. "Alright you two, let's get your lunch and send you on your way." Harry and the twins had created this routine shortly after they started living with him full time. Harry would make breakfast and depending on which mansion occupant was cooking at the school that day he would make them a lunch to take.

Natasha sat and sipped her coffee as Harry was moving around the kitchen and floating food into two lunch boxes. Wanda was packing a backpack while Pietro was racing around just above the speed limit Harry put in place for inside running. Pietro noticed Natasha watching him skirt the rules and gave her a sheepish smile. She just smirked and rolled her eyes at his antics.

Soon the twins were saying goodbye and giving out hugs before they stepped through the silver doorway of the Portal Frame, leaving the house quiet. Harry came up and wrapped his arms around Natasha kissing her head as he sighed. "Any plans for the day?"

"Not at all. Ever since that undercover mission went sideways, Fury has been keeping me local or working on non-undercover cases." Natasha said with a sigh.

"Miss being in the field?" Harry asked.

"Not the field so much. I just don't know where I fit anymore. I'm one of the best assassins in the world, but my fame has made it impossible to sneak around like I used to." Natasha said with some frustration as she leaned into Harry. Harry studied her for a moment before he smiled and picked her up. She let out a happy noise before twisting her body around and wrapping her legs around Harry's waist.

"Well my dear widow, why don't you teach." Harry said as he started flying up the stairs carrying her.

"Teach?" Nat asked as she peppered kisses along his neck.

Harry hummed in acknowledgement. "When someone can no longer use their skill personally, they pass them on to new people." Harry explained as they finally reached his room. "We can talk about that later, right now I have something else in §mind§." Harry finished with a hiss on her neck causing Natasha to shiver.

/OO-HP•SoS-OO\

Later that day, Harry was studying some runes in his workshop when he got a call from Tony. "Harry, I need you. Happy was hit in some kind of terrorist attack and he isn't doing well."

"I'm on my way. Meet at the Miami house?" Harry asked and got a quick affirmative from Tony. Harry hung up as he put away his project and raced upstairs to change. When he was dressed he stepped through the Frame and found himself looking at Tony pacing in his house. Pepper was standing to the side and an unknown woman was sitting on Tony's couch. She seemed surprised to see him and slightly nervous. Narrowing his eyes Harry took a quick peek at her mind and found a name, Aldrich Killian. Stunning the woman he turned to Tony, "You know Aldrich Killian?"

Tony, who was gaping at Harry for stunning his guest, was shaken from his shock when Harry mentioned Killian, "Yes why?" Pepper also perked up to listen.

"Seems she's working for him on some project called Extremis. I don't know the details but she has an agenda being here." Harry said. Tony then proceeded to tell him about the Mandarin and what he did. Harry gave him a deadpan look and just shook his head.

Both were now looking at the ground thinking about how it's all connected. They were all pulled out of their thoughts when a chopper was heard directly outside the house. Seeing it fire a rocket Harry waved his hand, vanishing a window, before hitting the rocket with a stunner causing it to blow. He then waved his hand again to transfigure the helicopter into wood. It quickly fell out of the sky and hit the water with enough force to make the wooden construct explode, aided by the munitions on board. Tony came flying back into the room with his suit on and flew down to the waters quickly to find someone to question. Harry just looked at Pepper and nodded his head towards the Frame. She got the message and grabbed her bag before taking a portal to New York.

"Hey Steve, mind doing me a favor?" Harry asked as he called his teammate. "Well Tony got into a spot of trouble with some ass who calls himself the Mandarin. He got upset when Happy got hit in one of the bombings-""Yes I know, but I need you at the Tower to make sure Pepper doesn't get kidnapped or pulled into this. Also be wary of a guy named Killian, he's connected, we just don't know how connected.""Yeah I'll tell him. Thanks Steve." Harry then hung up his phone in time for Tony to come flying up with a dude glowing orange and regrowing a missing arm. "Don't see that every day."

Tony dropped him in the middle of the floor but was startled as the stone floor started to melt. Harry waved his hand and reinforced the floor making sure it wasn't damaged further. Slowly the glow receded and the man was left lying there in half destroyed clothes and a new arm. "That was interesting." Tony looked up at Harry, "Want to do the honors?" Harry nodded before he moved over to the man. First he hit him with a body bind before leaning down and opening his eye lids. Doing a quick scan he found out everything he needed to know. Sighing and rubbing his temples he stood up "Get anything?"

"Yeah and it's not good. Turns out that Killian twat is behind 'The Mandarin' and is using it to test Extremis, basically a super soldier serum with a healing factor. I don't know the motivations but he has plans for you and Rhodey." Harry explained as he stood back up. "This guy is pretty high up in Killian's group and his next task was to kidnap Rhodey and take his suit."

Tony paced back and forth as he looked at the guy on the ground. His eyes even darted over to Maya, "What's Maya's place in all of this?" Tony asked.

Harry looked confused for a moment before noticing Tony's look at the girl on the couch. "Oh she's a scientist that works with Killian. I think she developed Extremis but I haven't looked for information pertaining to it yet." Harry explained.

"Well first we need to warn Rhodey, then we can worry about Killian." Tony said and that's what they did. Tony called Rhodey and had him come in with his suit, Harry gave a heads up to Fury about Killian, The Mandarin, and AIM. When they had everything covered they left Rhodey to watch over the prisoners as Tony took Harry to the hospital that Happy was at.

Walking into the room Harry saw Happy covered in bandages, burns peeking from under them. Harry moved over quickly and summoned out some burn heal ointment before slowly covering the wounds on the side of his face and arm. Soon Happy was looking mostly healthy with the exception of the bruising around his ribs and back. Harry used a few healing spells to help make them better before he woke him up.

Tony watched as Happy went from part mummy to mostly healthy in minutes. He smiled as one of his oldest friends barely opened his eyes. "T-Tony. People bombs." Happy said with some effort as his throat was still raw from the heat of the explosion. Tony and Harry both gave Happy an incredulous look before Harry helped him sit up and gave him a glass of water.

"What did you say Happy? People bombs?" Tony came and stood beside the bed as he watched Happy gulp down the glass of water. Happy coughed a few times before he settled back down and looked at Tony and Harry.

"Yeah the bomb that I got caught up in was a person. Not like he was carrying one either. No, his skin started glowing orange before he exploded!" Happy explained before slouching back down, still tired. Harry patted his shoulder before giving Tony a look and stepping outside.

"Well you just rest here buddy. I'll take care of this." Tony said as he lowered the back back down and Happy fell back asleep. He stepped outside where Harry moved from along the wall to walk with him. "People who blow up." Tony hummed in thought. "He was also glowing orange like that guy we found attacking the house."

"Maybe Extremis isn't as stable as we thought." Harry said as they finally exited the building.

"What?"

"What if Extremis doesn't always work? What happens to the failures?" Harry asked.

"You don't mean…" Tony cut himself off as he started thinking over everything they knew so far. "What if super healing wasn't the goal? Maybe Killian wanted undetectable bio bombs instead." Tony explained with some dread, but Harry shook his head.

"From what I could tell Killian didn't make Extremis. I think he's just profiteering from the negative reactions." Tony hummed in though after listening to Harry. Soon they were back in the car and on their way to the house.

"Either way we need to track down Killian and stop whatever he plans on doing." Tony said and Harry agreed. Soon enough they were back at the house and standing before Maya and the soldier. "Let's question Maya. She'll have more answers about Extremis than the soldier anyway."

Maya woke up to find herself tied to a chair looking at Tony Stark, James Rhodes, and an Avenger, Summoner. "Tony what are you doing?" She asked nervously as Tony was giving her a glare.

"Maya, what's the real reason you came here?" Tony asked.

"What do you mean?"

"We know about Killian, AIM, and Extremis. We found out about the human bombs that have been going off. We even know you were working with Killian. Now tell me what you know of Extremis." Harry in his Summoner garb elaborated. Maya seemed to deflate in her seat and looked at the ground.

"I was working on a way to help people with all kinds of degenerative diseases. I found a type of serum using nano tech that can reprogram the DNA of the human body, allowing it to trigger regenerative abilities inherent in the human body." Her voice started off flat before getting more animated as she talked about her creation. "I could never get it to work though. You helped me create a more stable version when we met at that conference years ago Tony. From there it was just trying to increase the success factor. Aldrich came and found me. He used the resources of AIM to fund my research and we started human trials. Veterans with amputations of missing limbs were used and we found some success. Our first success showed massive amounts of regeneration, strength and stamina. There were some side effects we didn't anticipate. All successful subjects output a tremendous amount of heat. Their body was expelling heat in huge quantities due to the regenerations effects."

Harry had been listening to the side but when she mentioned the amount of heat being released as a byproduct of healing his head snapped up and he stared directly at her. "How much heat?" Tony and Rhodey both looked at Harry strangely when he interrupted. Maya gave him a confused look before answering.

"Well most subjects could melt metals with their bare hands. Some could even breathe fire." Maya explained. Harry started pacing and mumbling. Tony grew concerned and approached. He grabbed Harry's arm as he passed by causing him to look up. Tony almost let out a gasp when he saw Harry's eyes glowing a brilliant green.

"What's going on?" Tony asked. Harry shook himself loose.

"Sorry about that. We can talk about it later. First we need to figure out what Killian's plan is." Harry then jutted his chin back at Maya.

"I don't know what Killian has planned. I just wanted to finish my research." Maya started to frown as a few tears left her eyes. Tony sighed as he rubbed his face.

"Do you know where he is?" Tony asked.

"He has a mansion in Miami."

AN: Just to answer some review questions.

No Coulson is not running that team. Since he never died he is now a much bigger part of the leadership of SHIELD. Hand is still running the HUB in case you were wondering as well.

Also as of right now the only members of Harry's 'Harem' will be Natasha and Ororo. This could change, but is unlikely.
