ATTENTION! IMPORTANT NOTE:

If you started reading Harry Potter: SHIELD and Sorcery before July 27th, 2024 then I would highly suggest you start over.

I have gone through and edited my previous chapters, and added new ones to expand on Harry's time in the Marvel Universe.

Some things will be very similar and others were deleted and rewritten from the ground up. I'm not saying there won't still be problems with grammar or misspellings, it is very hard to see your own mistakes when writing.

Also Sorry I've been MIA for a few days I was just finishing this up and will now be reposting and adding new and old chapters.

Thanks for reading

Harry whistled as they walked through the Expo. "This is nice Tony. Lots of up and coming inventors." Harry noticed a display that had a piece of equipment called a re-breather. Harry saw many more Stark Industries booths with new things they were working on, clean energy projects and projections, new line of phones and tablets, and something that looked like a floating car.

Tony nodded along, "A lot of the people not working for SI that show up will get brought in if the idea has merit. The SI booths are mainly just showing off what we will be releasing and focusing on over the next few years." Tony greeted a few people he knew as the continued to a staging area backstage. "We quit developing weapons, as you know, but I still needed somewhere to put my large research department, so I figured the advent of mobile phones could use some Stark innovation."

Harry gave a humor filled look at Tony, "Compensating for something with your large research department?" Tony gave him a withering look as Harry bust out in chuckles. "Well with what we're working on you'll still be at the forefront of the industry. With me of course."

Tony gave him a strange look, "With you? Are you saying you want to work with me officially?"

"No, I am saying I made my own company. You are looking at the new CEO and owner of Magic Innovations!" Harry finished with a flourish of his arms and a slight bow.

Tony was impressed, "I can buy in right?" As Harry nodded Tony kept considering it. "You know this is an excellent idea. Anything we develop that might be used improperly could be put under your company. Any idea where you'll make your headquarters?"

"One of two places at the moment, New York for obvious reasons and London because it's home." Harry answered easily as they came upon Pepper being badgered by a smarmy looking business man. "Looks like Justin Hammer is trying his charms on your girl Stark."

Tony smiled a bit, "Then he has no idea who he's dealing with."

"Back her up anyway? I always love being a smug prick to smug pricks." Tony laughed and agreed. They walked up to Pepper and Harry started it off by using his most aristocratic British lord's accent he could, "Miss Potts, so lovely to meet you again."

Pepper gave him an amused look when Justin Hammer poked his nose in, "Who are you?"

"Oh forgive me, Miss Potts can be so demanding of one's attention when she nears. I am Harry James Potter-Black, Lord of the Most Ancient and Noble Clan of Potter-Black, Duke of Gryffindor, and Earl of Blackmoor. Who, are you?" Harry said, full stiff upper lip and condescension dripping from his whole attitude. Tony noticed that Harry had somehow pulled out a couple of signet rings and placed them on his hands.

The entire group seemed surprised at this, "J-Justin Hammer" he said stuttering a little bit. Tony was just standing there hiding his laugh behind his typical smile. "Ah yes Mr. Hammer, terrible tragedy about that pilot in you experimental suit." Tony couldn't hold back the chuckle anymore and Harry was about to continue when he felt something appear in his pocket. "Excuse me something has come up." He walked a few feet away to pull out a note from his pocket, Harry, Mordo has disappeared tracking down a group of fear demons. I need you to retrieve him. His last known location was at an Aztec ruin in Central America. Harry quickly walked back over to Tony, "Sorry Tony but I must go I'll get in touch later." Before Tony could say anything he walked away before popping to the New York Sanctum to use the Rotunda Gateway.

Tony was left standing with Pepper and Justin Hammer, "Well that was abrupt. Anyway Hammeroid, we'll see you later." Tony led Pepper off before Hammer got another word out.

Harry's trip to central America was quick. He used as series of chants to eventually find the site of the dimensional tear. "Shit." He quickly summoned a patronus for a message, "I am going to cross the border. I'll be back soon, prepare a healer." and sent it to Yao to let her know that he was crossing over.

Harry donned his battle attire and quickly focused his powers and with a concentrated split of his palms, tore a hole into a minor fear dimension. His first step through was accompanied by an extreme level of fear. "Merlin this feels like Azkaban."

Surrounding him was what looked like waves of darkness. Craggy mountains and barren wastelands went as far as the eye could see, the air smelled of filth, like dust and rot mixed together. The sky was a nexus of dark silver strands being pulled into the ground far away. Legions of demons were making noises and feeding on trapped souls over the surrounding mountains. nearby a reddish glow radiated from a cave. Harry making his way over started to hear hissing noises from all around him. The fear that pervaded the realm was amplified up to eleven, from the walls of the cave came Fear Eaters shifting with an almost slurping from all around him. "Kkallakki, which means Kkallakku is near." Harry spat in disgust.

Harry wasted no time waving his hands unleashing waves of air blades that made mincemeat of the floating lesser demons. He started sprinting as the horde continued to pour after him, fear and nightmares edging at his mind protections, screams from people he could never save pervaded his mind. His anger started feeding his magic, his hands moved in arcing sweeps shooting out waves of his scarlet red flames, kicks punches launching earthen spikes, felling tens and hundreds by the minute. His hands and feet flew through the air, each movement blasting magic and elements at each of his enemies, he summoned creatures of earth and air, slicing and crushing the horde hounding him. Blasts of pure magic tearing demons apart, conjured weapons following his movements and slicing the endless hive of enemies into pieces. His sword a blur of motion as he sprinted towards his fellow Master.

He dashed down the tunnel taking turn after turn, killing fear eater after fear eater, the flames of his magic growing brighter and hotter with each suppressed memory unleashed. Suddenly he found himself in a large room, Mordo and two women suspended above a ritual circle wisps of energy being drained into crystals nearby.

"Oh so the Sorcerer Supreme sends me a another husk for the harvest." Kkallakku's hissed, his voice was scratchy and ethereal in a way that made it seem like it was spoken by multiple entities, but grated on the sense like nails on a chalkboard. "Come husk, let me feed on you!" he shot down from the elevated position he took to slowly steal the energy from the sacrifices.

§I will enjoy tearing you apart Demon§ Harry stomped his feet and jumped toward the the flying snake demon, who was surprised at hearing the serpent tongue from a human, with earthen spikes on his hands and red bands around his arms. He met the demon mid-air with force, he threw a powerful uppercut flinging the demons head up, followed by twin blades of wind that skirted off his hide with a horrible screech. Harry jumped back to start another attack when the tentacles sprouting out of Kkallakku's body started shooting beams of energy, each one feeling like pure fear. Harry swiftly moved around them throwing a shield charm off to the side and watched as it bounced off the shield. As the barrage continued he summoned shields on both hands and sent the attacks careening off to the sides. When he finally saw an opening he took one step forward and launched himself forward summoning his sword into his raised hands leaving a shallow gash along the bottom of the flying snake demon.

"Haha, puny mortal. Your hits do nothing." Kkallakku laughed as Harry focused more power his earthen spikes turning them into diamonds, his hits digging light scratches into the demon's hide.

Harry huffing back on the ground looked at the Fear Demon above him as score more of it's children surrounded the entire cavern. Memories of his own world, the fall of Hogwarts, the destruction of Britain, and the eventual death of all his friends. He summoned a horde of patronuses that quickly crashed into the horde of fear demons causing some damage but not enough to finish them off. Cursing under his breathe when he summoned a bag of crushed unicorn horn and his phoenix flames before he slammed them together creating a powerful wave of purification.

Kkallakku's mirth was quickly wiped away as he felt a primal level of revulsion to the Sorcerer's new attack, "What magic is thissss?!" His hiss becoming more pronounced with pain that shot from a small lash of the purifying flame.

Harry seeing his attack working covered his sword in the new liquid like flame that burned in his hands. He jumped and staring swinging hit after hit to the now screeching demon. His sword bit deep into the scales of the Greater Fear Demon causing black corrupted blood to spill from Kkallakku's body. The flames from his sword sticking to the wounds leaving smoking lines of burnt flesh after only moments, the waves they produced reducing the hive of creatures in the background into a hill of corpses and ash. He jumped from the ground up to the ceiling coiling his power before he launched himself downward, his body spinning like a top on it's side, his flame covered sword fell down with such force into the head of Kkallakku that it split right in two rattling the entire cave with the force of the attack. Kkallakku slammed into the ground, cauterized wounds littered it's body it's head split almost completely in half. Harry stood back as the wave of children his enemy summoned were sent running from the Sorcerer covered in the flames that could damage their parent. Knowing enough to know that he couldn't truly kill a Fear Lord in his own realm quickly moved to free Mordo and the two women, "Come on Mordo, let's get you home."

When Harry's hands neared Mordo he seemed to come to himself, "Potter…we" he stumbled in weakness, "We need to destroy the crystals and bring those two, he can't have the souls of two innocents, or we might never recover from the damage he could do." Harry nodded as he half carried his fellow sorcerer. He made a negligent wave and the crystals turned to dust and the two women turned into dolls and flew into his expanded pocket.

He heard the Fear Lord starting to stir behind them, "Mordo we need to leave now, I haven't defeated him for long and he may call his allies to help." Harry quickly tossed Mordo over his should before he popped away to his arrival site and used the lingering connection to make a portal home. It wasn't until he was once again standing under his own sky that he finally felt the strain holding back the pressure of the Fear Realm. He collapsed on the ground Mordo hitting the ground nearby. "You good over there grumpy?" Harry asked almost needlessly as Mordo was quite audible in his grumblings to being dropped.

Mordo landed on his back after struggling to flip over, "Seems I owe you a debt of gratitude Potter." His breath coming to him in big gulps no longer stained by the inherent vileness of a demon realm.

It was only a few hours later that Harry was relaxing with some tea and Yao, having told her about what had transpired. "So you're saying this 'patronus charm' helped damage a Fear Lord? Fascinating."

Harry nodded his head after setting down his cup. "Yes, not as much as I would have liked, but if we ever have them come to our realm it should od well enough to damage them here. Facing them in their own realm made it a lot less effective. I had to use some of my unicorn horn to defeat him."

Yao exclaimed, "Ah the so called 'battle alchemy' you've told me about."

Harry nodded, "Yes it's a resource intensive magic and considering I don't know of any local materials to replace it I hold back from using it too often. When I have the time though I'll see if I can throw together something similar to the patronus for the other Masters."

Yao nodded, "Yes I imagine they would be quite pleased." She took a short moment to give him a reassuring look, "It seems since your arrival in our world the demons have gained a foothold to make their invasions easier. The ritual you used might have tread their realms to make it here." Harry groaned and dropped his head to the table, "Do not worry Harry the trail you left behind should be inconsequential given time." He gave her a light glare to which she laughed, "Yes you might have cause it but your power bolsters our own. So technically you are paying for it anyway."

Harry sighed sitting back up, "Well be sure to let me know if any of my trailers come barging through." He was about to continue when his phone rang. He pulled it out giving Yao a near silent sorry. "Harry speaking."

"Harry? It's Pepper, things are going crazy over here, that guy with the whips showed up at the Expo and is now trying to kill Tony and my assistant was -" Harry shot to his feet when the called dropped after hearing a nearby explosion. "Sorry Yao I-"

"Must go yes. Do not worry about Mordo or those two women, we can take care of everything. Have a good day Master Potter." She said and sent him off with a smirk.

Harry nodded and popped away quickly. He reappeared near the flying car display when he saw a series of humanoid drones laid all over the grounds of the expo. Buildings on fire, cars flipped and destroyed, and the glass roof shattered everywhere. He swept the around looking for Pepper or Tony when he saw the obvious signs of battle he raced over. What he found was Tony and a gray and blue armor fighting against a much larger armor with huge electric whips. He wasn't too worried about Tony so he left to make sure Pepper was safe. When he found her she was directing other civilians in the directions away from the center of the Expo. "Hey Pepper you seem busy."

Pepper turned at his voice and visibly relaxed, "Thank you, would you mind going to help Tony? I'll continue to wave away civilians."

Harry gave her a big grin, "Nope!" He popped the 'p'. She gave him a questioning look, "Look Tony is a big boy, he's got back-up. I'm sure he is much more worried about you than he is his own fight."

Pepper gave a resigned nod while continuing to direct or wave off people fleeing the battle while Harry kept discreetly shooting down drones. It was only a minute or two later when the drones all over the ground started to beep in tandem and Pepper's phone rang. Harry wasted no time in grabbing her and popping away to a roof in his line of sight.

It was only a single minute after they got to the roof that all the drones blew up in spectacular fashion and Tony came flying down with his gray suited buddy came to land on the roof. "See I told you Pepper, Tony took care of the big bad."

Tony lifted his face mask and gave Pepper a big smile walking over to hug her, "I was worried I wouldn't find you in time." Both Tony and Pepper were just looking at each other.

Harry coughed off to the side standing with Rhodey, "You gonna kiss her or what Tony?" Him and Rhodes both grinned at the blushing pair before Tony took the encouragement and kissed her. Harry held out his hand to Rhodey who game in a low five. "So how was the suit?"

Rhodey just groaned, "Remind me to never use Hammertech again." Harry just laughed.
