Tony's mind whirred through all the different people he met who might enjoy a new arm before he zeroed in on a a professor from Columbia, "Yeah there is, a Dr. Curt Connors, lost his arm in an accident years ago. We can call him into a lab at SI in New York, the tower isn't finished yet but the labs are functional."

Harry chuckled, "Did you just casually drop that you're building a tower in New York City?"

Tony smiled smugly, "Of course I did. I'm going to put my name on the side of the building and everything."

"Tony Tower? Ridiculous, all good bits of alliteration have three words at least." Harry chuckled.

"Pfft, what, no, it's going to be named Stark Tower." Tony couldn't help but spit the water he just drank when he heard Harry call it Tony tower. Seeing the satisfied look on his face he would assume he did that on purpose, "Oh yes ha ha make fun of the guy with a tower. I was going to offer lab space in my tower."

Harry rolled his eyes, "Tony you saw my pile of gold and jewels, I can buy my own tower. Let's start packing this prototype up and clean up." Harry said moving around the workstation and putting away his books and inscription set, "Regardless I will take you up on that offer of lab space for a while. Though I technically own a business I have no employees or headquarters yet."

"Speaking of your business, when does it go public?" Tony asked as he led Harry out of the lab.

"Why would I want it to go public? To deal with a board of directors I don't like? No it's going to be privately owned. I don't need investors, but you are free to buy in because I want you to work with me." Harry explained as they walked upstairs.

Tony didn't know how to respond to that so as they got to the living he just asked, "You think Pepper would let me name the tower 'Tony's Tower of Tech'?" Harry's only response was to laugh.

It was only a few hours later that Harry and Tony walked into a lab at the future Stark Tower with a middle aged man with sandy blond hair and missing one arm at just above the elbow. "Well Dr. Connors this is technically a prototype but I have a good feeling about it."

Dr. Curtis Connors couldn't believe his ears when he got a call from Tony Stark of all people to test out a new prototype prosthetics. Yet here he stood in a Stark Industries lab with Stark and his associate telling him about how the prosthetic works and what it could do. "So you're telling me it will have a sense of touch?"

"Well that's the idea. Problem is we can't test it ourselves, for obvious reasons, and we would prefer someone who could give us a more intelligent answer about the sensations" Tony explained as he was measuring out the prosthetic to Connors arm.

Harry and Tony eventually got everything set up for a mediocre fit, nodes on the back and spine to give it the idea it uses finer muscle control to move and control. The arm itself was handing on his shoulder were his arm used to connect. "The fit isn't perfect but it should work for now. Now make a fist…"

Connors followed the instructions throughout and was flabbergasted when they starting testing out the sensations of the new arm. "It can feel? That's incredible."

"Yes but it doesn't pain or pleasure yet. Just the feeling something is there and temperature change." Harry explained as Tony was doing the final strength and dexterity tests. "So how does it feel?"

Connors had a look of happiness as he picked up a pencil and piece of chalk. "It's wonderful. I never thought that prosthetics would reach so far in my lifetime."

Harry nodded as Tony started inputting measurements into the computer. "Yes well we can only hope that it gets better from here. We'll get you set up with a custom one before you head out."

"I get to keep it?" Connors asked quite surprised.

"Well sure, we know it works the way we intended it to, if we upgrade it we can call you, but testing is done. So you can keep it." Tony said waving off Connors from declining it.

Connors didn't quite know what to do with himself until Harry walked up asking about his research, "Well, due to my circumstances, I started working on a line of research delving into cross-species genetics. I wanted to use animal DNA to help heal and prevent sicknesses."

Tony popped up at that point, "I remember you giving a lecture on it at a conference a while back. Using lizard DNA to regrow limbs and Zebra fish to heal Parkinson's patients."

"That is correct. Unfortunately there isn't much money in something as radical as my subject of research. I had hoped to make myself whole once again." Connors said as he flexed his temporary prosthetic.

Harry gave him a considering look. Cross-species genetics was trying to do things that potions from his old world did already. You could regrow limbs and heal most diseases with a few spells and potions, granted there aren't any curse scars in the way. He was tempted to hire the man but knew that he had a lot on his plate at the moment and upcoming events would make everything a bit crazy for a while. Harry's thoughts and Connors and Tony's conversation were both interrupted when Jarvis spoke up, "Sir, the parts for the new prosthesis are ready for assembly."

Tony turned to look at Connors, "Well this is it. We could leave it as a node based prosthetic but you would need help putting it on, or we could mount it on. It's up to you."

Connors gave tony and his temporary arm a look. He took several minutes debating about whether he would get a chance to finish his work in his lifetime and how much having two hands would help him. He closed his eyes and nodded, "I'll go for the mount, if you don't mind."

Tony and Harry exchanged a look, "Sure not a problem. Harry can do it all here with not invasive cuts." Harry pulled out a vial of water and turned it blue before handing it to Connors.

"Just take that and when you wake it'll be all done." Harry said as he placed a hand on Connors back, when he tipped back the colored water he stunned the man and let his head hit the back of the chair. "Well this isn't what I thought we would be doing today. Any cameras in here?"

Tony shook his head. "Nothing that other can see, just Jarvis." Harry nodded as he grabbed some sample metal of the same type as the prosthetic itself and sat next to the arm he was attaching it to.

Harry let magic flow from his hands into the metal and slowly shaped it to be a perfect fit for Connors shoulder joint, it molded to the shoulder back and chest as Harry created a slot to hook the arm into. Tony watched in amazement as Harry finished molding it and bonded it to Connors shoulder blade and skin. When he stepped back it look like he painted the shoulder with titanium. "That was incredible! How did you do that?"

Harry was looking over his work to make sure the new prosthetic would connect easily. "That is a special technique I picked up from my Alchemy teacher. It's called transmutation. It's a form of transfiguration, changing one object to another, and allows the caster to mold objects or materials with their magic. Since I don't use a wand, I get a more hands on experience." Dusting off his hands and stepping away from Connors, "Lets get the new prosthesis inscribed, built, and attached."

Opening his eyes Connors looked around the lab and spotted Tony and Harry eating over at a nearby table. Harry noticed him first, "Hey Connors, you hungry?"

Connors was at first confused before he realized what he was doing here. He looked over at his right arm and was baffled by the metal covering his shoulder that connected to his new prosthetic. He gently raised himself expecting pain and felt perfectly fine. There wasn't any pressure besides having something where there was nothing. He moved to stand and marveled at his new arm. It felt fluid and quick.

Harry and Tony watched as Connors moved his arm just watching it. Harry sent a smile and small wink before tossing a bottle of water, "Connors, catch!"

Connors eye moved over and he reactively sent his new arm up to catch it. "This is amazing. There isn't any lag and it feels like my other arm. I can feel the bottle in my grip." He said as he flexed his fingers around the bottle in his hand before it suddenly cracked spilling water on the ground.

Harry dusted his hands from the sandwich he was eating, "You'll need to be careful with anything delicate for a while so you can get used to gripping with a metal arm. It isn't all that strong comparatively speaking to normal arms, but it is metal."

Connors nodded as he stepped around the water, "I don't know how to thank you for this."

Tony waved him off like he had earlier, "Don't worry about it too much. Keep it on the hush hush for a little while so we can keep working on it before the public learns of our new prosthetic line. We can't mass produce them just yet."

Connors nodded, "If you two need anything be sure to let me know. I want to go show my son when I pick him up from school."

Tony and Harry gave him a spiel about upkeep and to let them know if anything goes wrong. They cleaned him up and watched him walk out of the tower with a pep in his step. "So… Want to make some magic armor?" Harry asked without looking at Tony.

Tony just laughed as they reentered the elevator, "First I want you to teach me how to use runes properly."

Harry just nodded with a smile, "Fine let's head to my place then. I got all the tools you'll need." When they got back to the lab Tony grabbed his stuff and followed Harry through a portal to the yard of what could be called a typical English manor. The yard was bereft of a driveway but had a walking path paved in stone that trailed between gardens and next to a pond with a small pier. The house it self was a nice two stories, large bay windows took up the ground floor and a set of double doors of wood with intricate designs of glass and metal. The second floor was dotted with shuttered windows and the building itself was made of pure stone with wood accents, it was capped with a typical triangle roof with the exception of a circular tower on the edge that had a roofed balcony that acted as a third story.

Tony whistled, "Nice place. A little rustic for me and I don't see a place for cars?" Tony asked towards the end.

Harry gave him an unimpressed look, "How did we get here? Do you even know where here is?"

Tony immediately got it, "So how far from the nearest road are we?"

"Naturally? About half a kilometer. With my enchantment up? About 6 kilometers." Tony gave him an expectant look. Harry rolled his eyes, "I used magic to ward off the land I bought, I then increased the area of the warded land so instead of being about a square kilometer it's 10 square kilometer. Either way come on, we can head to the workshop."

Tony walked through the front doors into a large entryway, the walls were all a light colored wood with dark wood accents. The foyer was well lite by a floating chandelier, the stairs going up wrapped the walls on both sides. Three doors led off from the hall while upstairs went into a singular hallway that he assumed spread from one end of the house to the other. Harry led him towards the door on the right where they entered a large and modern looking kitchen, it had a 6 person table set in the center with the appliances and cook utensils lining the far wall. To the right of where he entered were three doors. Two were opened leading to large dry storage areas and the final one was their destination. Harry opened the door and led him down a set of spiral stairs. Tony saw the empty doorway and walked out into a veritable wizarding tower. There were bits and bobs sitting on desks, lights floating to and fro with no reason in sight, books dominated every wall and desks with chairs were spaced throughout. The most impressive part to Tony was clearly Harry's work area, it took up a large area in the corner, the shelves were immaculate and held so many different materials Tony couldn't identify and the large table in the center was layered in runes from so many languages he couldn't imagine having the time to learn them all, above the table was a gathering of pinpricks of lights in loose forms.

"What do you think?" Harry asked as Tony subconsciously moved to his work area.

"This is really impressive…whatever it is." Tony said trailing a finger just over the layers of runes on his work table.

Harry laughed, "This is basically a holo-table using runes. It took some effort and I had to look over a few artifacts from my old world but it worked out pretty well." Harry drew up a quick set of runes and let the table display them, "It's more of a projector than an interactive table but it's useful when I need a 3-d image for something I'm working on."

Tony nodded as he continued to study the different languages, "So what language are you going to teach me next?"

Harry shook his head, "No I won't be teaching you like that. First off that would take forever, secondly, you're a genius Tony. I'm not trying to inflate your ego," Harry said when Tony started smirking, "but it would be a waste of your talents and mine for us to go about it like they did in my school. No I'm going to teach you the foundational knowledge and then let you loose in this library, it has copies of my more used books including a lot of runic languages."

Harry then sat down with Tony and started lecturing on how Inscriptions work, why they work the way they do, and how different languages can work together. First he covered the history of runes as a language of dimensional beings used to interact with energies present throughout the universe. Then he covered how Wizards and Witches started using runes for enchanting and rituals, "Runes were the sole way humans could do magic at first. Everything was a ritual or weapon that could be modified with runes."

Harry then went on to talk about the different languages, how they were modified over time and the true test of Runic Mastery, "So you see when a true master of runes comes about he's called a Rune-smith, because he can take runes and merge them together like a blacksmith to make something new. See here this rune is a rune word I created for a stasis charm. It combines the Time Rune from Sanskrit and the Life Rune from China, of course it required a bunch of enchanting and other inscriptions but that rune allowed life to be present in a stasis field. Either way the ultimate test is to create a new rune word using the languages we started with." Harry watched as Tony studied the rune he had created before he glanced at the clock, "Ugh we should go get something to eat, and you need to check your phone."

Tony barely looked up from what he was studying, "Why?"

Harry tapped Tony's watch, "It's nearly 8:30 PM Malibu time and we woke up early today."

Tony groaned as he stood up. He cracked his back and checked his phone sighing when he realized he didn't have service. "Fuck. Pepper is going to chew me out."

Harry gave him a glance when he cursed only to see his phone didn't have service. Harry grinned, "I knew I forgot something when bringing you here. I needed to add a signal booster to your phone."

Harry opened a portal back to the Malibu house and Tony's phone immediately blew up with waves of messages and missed calls. Harry patted him on the back as he moved to the kitchen, "Just call her and get it over with. In fact invite her to dinner, I cook a mean shepherd's pie"

Tony walked off to the side as he called Pepper and Harry headed to the kitchen to cook. He was surprised when he walked into the kitchen to find it had a visitor in by the name of Nick Fury, "You hungry too Fury? I knew you liked when I cooked last time." Harry then proceeded to act like Fury being there wasn't a big deal.

Fury waited to see if he would stop so they could talk and when he actually started cook the vein on the side of his head started pulsing faster and faster. "Look Potter I need to speak with you and Tony, so go grab him and get back here."

Harry gave him an unimpressed look, "Yeah no we can talk over dinner." Fury just sighed and slammed his head into his palms with the thought 'Why me?' echoing in his head.
