Chapter 1

Tony Stark was a man of many secrets. He kept his secrets closer to him than anything else. No one knew his greatest secret, not Pepper, not Happy, not Rhodey and not even JARVIS and certainly none of the Avengers that were all living in the newly named Avengers Tower.

He knew the Avengers and his three closest friends were getting worried about him. For almost a year Tony had been acting more unusual than he normally did. There was less eating, less sleeping and he checked his phone every few minutes before he eventually stormed out of the room in frustration. Something was up and they didn't know what to do. Even Pepper couldn't get him out of his funk.

Well, that was until one day JARVIS announced there was an incoming call from an unknown number, Tony was out of his seat in the blink of an eye demanding that the AI answered it and put it on loudspeaker. The Avengers all crowded around as the call was connected, Happy and Pepper standing the closest to Tony when they noticed the truly stressed look on his face.

"Hello?" Tony spoke up, looking so damn hopeful and shaky that it shocked everyone in the room. It was silent for a few moments before a voice, an English one to everyone's surprise, spoke up.

"Hey dad." The teen's voice said on the other end, shocking everyone in the room, before Tony slumped to the floor, sitting on his knees as he started shaking out of relief.

"Harry? Where the hell have you been? It's been a year since I last heard from you! You are in so much trouble, 17 or not." Tony said, trying to keep his voice from trembling. There was a small sob on the other end of the phone that made Tony tense up even more.

"I'm so sorry dad. I… I don't have a lot of time left so this call needs to be quick. A lot has happened in the last year. Dumbledore died, I don't think I told you that, Snape killed him but he was good- he's dead too. Voldemort…" Tony tensed at the name before focusing as his son continued on, "The war's started dad. We've already lost Fred and Remus and Tonks. Oh god my little godson is alone." There was more sobbing and finally Tony let the tears fall.

Meanwhile everyone else was confused. War? Steve and Thor were the most confused. War was no place for children. Everyone stayed quiet as they listened to Stark's son continue.

"I love you so much dad and without you I would be lost in this world. Just remember that you are the most important person to me and I will never forget what you did for me." Harry said shakily and Tony was choking on his tears by now. Even Pepper was teary eyed and she had never even heard of Harry before this.

"S-Sounds like you're saying goodbye Hare-Bear. Why...?" Tony was helped off of the floor by Bruce and Clint as they realised he couldn't move but needed to be standing. "Harry turn on the camera." Tony demanded in a harsh voice, his answer was a simple sigh before there was a click and the image flickered to life on the screen. Everyone was, again, shocked and Tony had to be caught by Steve before he collapsed to the floor again. This time Pepper really was crying.

The teenager on the screen looked like he had infact been through a war. His face was covered in dirt and blood, he had bags under his empty looking green eyes. His hair was messy and hanging limp, he looked worryingly underweight and in the background they could see trees and a giant castle. Nevertheless, everyone could honestly say he looked like Tony. Harry had tears running down his face.

The boy brought the camera back slightly before bringing a golden ball to his lips.

"I open at the close…" Harry murmured as he read what the writing said on the ball. "I am going to die." He finally said in a strangely calm voice and the ball opened revealing a black rock.

Tony let out a strangled sound when he heard his son say that, his precious baby boy. His most precious secret and his reason for living.

Harry turned back to the camera and gave a watery smile as he focused on his father.

"I love you dad, you're an incredible man and don't let anyone else tell you different. Tell Sirius that I love him too and I know he can take good care of little Teddy." And with that the screen went black. Tony let out a wordless scream of pain as he pushed away from everyone and started typing away on a panel, focus entirely on the screen. Natasha spoke up.

"Stark what the fuck is going on?"

Tony answered without looking back, "My son. No one knows about him, too much danger. He's a Wizard and goes to a magical school. They're at war. His godfather almost died in his fifth year but he survived and he's been in the tower ever since, he's on his way up as we speak. I have secret droids stationed around Hogwarts that I sometimes use to keep an eye on him, I created some technology that doesn't get destroyed by magic. Ah hah!" Tony crowed as several images came on the screen.

Tony stepped back with a gasp as he saw the destruction all over Hogwarts and at the same time a tall, long haired man ran into the room looking worried.

"Tony, what happened? Where is my godson?!" he bellowed as he stood next to Stark, the man too looked shocked as he saw the state of everything. Everyone else stepped back to give the two the illusion of privacy but didn't move far.

"Voldemort's started the war. He's at Hogwarts." With a few move clicks on the panel the screen focused on a forest. There was a bald looking snake-man who was surrounded by people. A large man was in chains and looking nervous as the pale man paced. No one said anything as they listened to what was happening.

"Where is he? I thought he would show." The snake-man- Voldemort, Tony told them- said in a weird hissing voice. Suddenly Harry was there, a shimmering cloak dropped to his feet and everyone's attention focused on him. Sirius was now looking close to tears and Pepper was sobbing into her hands. Her weakness had always been children.

They all watched helpless as the giant man- Hagrid, Sirius told them- started telling Harry to run before he was silenced. Voldemort gave a nasty smile as the people- Death Eaters, they were again told by Sirius- around him started laughing maniacally.

"Harry Potter. The-Boy-Who-Lived, come to die." Voldemort said maliciously before he screamed 'Avada Kedavra!'. Sirius and Tony screamed out as they watched the green light hit the boy. Harry collapsed lifelessly to the ground and the Death Eaters in the forest all started cheering.

Natasha gripped Clint's arm, stopping herself from showing any grief even though all she wanted to do was slaughter every one of those bastards. That was a child. Clint couldn't help but think of his own children and what he would do in that situation whilst Bruce grit his teeth, his eyes flashing green, Steve bowed his head and Thor watched with a solemn expression. Pepper was still sobbing and Happy held her up, his own face showing intense grief as he watched the dead body of his best friend's secret son.

As Tony and Sirius could do nothing but cry and look at the lifeless body of their little boy, the Avengers noticed Voldemort become unsteady, having to be held up by a few of the Death Eaters.

Sirius and Tony soon paid attention- Sirius conjuring up a seat for everyone, all but Thor hesitating to sit at first, and the two grieving guardians practically collapsed into their seats as they watched as Sirius' cousin confirm that Harry was indeed dead.

"I can't watch this anymore." Tony muttered through his tears and changed cameras so they were now watching Hogwarts. Sirius made a choking noise as he saw the state of his old school. Tony was no longer crying, he just had a closed off expression whilst his eyes looked as empty as Harry's did. The only difference being the colour.

Tony turned to Sirius, "Harry said that he loves you and that he trusts you to take care of little Teddy. Remus and Tonks didn't make it." He said softly and Sirius finally started wailing, his whole body shaking as he curled in on himself. Pepper was wiping her eyes with a tissue as Happy had his arm around her. Steve and Thor were still looking solemn as they sat next to each other, Natasha having to close her eyes as she saw the bodies of children at the school and Clint tightening his grip on his best friend as he held her. Bruce's face just crumpled at the sight, obviously wanting nothing more than to smash everything but staying put as support for his best friend.

It was in that moment that Nick Fury and Phil Coulson walked in only to pause as they saw something clearly classified on Tony's screen.

"STARK-" Fury didn't even get to finish before he was on the ground, Natasha standing above him cracking her knuckles, pain radiating through his cheek and jaw. Tony stood up, crying again but ignoring it to frown at the two men.

"Either get out or sit down and shut up. I have just lost my son and I don't want to hear either of your bullshit." Tony said firmly and- after sharing a bewildered expression- Fury got off of the floor and they sat in two newly conjured seats thanks to Sirius. Fury obviously recognised the wanted criminal but kept his mouth shut, although his hand went to his belt where his gun was.

They finally settled down again, Tony nodding his thanks to Natasha who looked oh so pleased with herself, and focused on the screen again.

Fury and Coulson had no idea it was that bad in the Magical world. They had lost contact some time ago and they had no clue what was going on and none of their spy's could get any intel.

There was movement on the screen and they all watched with bated breath as children, teachers and families alike walked slowly out of the school entrance, all looking rather battered. Sirius recognised the Weasley's quickly and he was saddened to see only one twin- realising the other was either injured or dead. Neville had certainly grown into himself and Hermione and Ron were clinging to each other as they looked to the other side of the courtyard.

There, Voldemort and his army were approaching. As they got closer they all noticed Hagrid carrying something and Sirius let out a moan of pain as he realised it was Harry's body.

"Harry no…" Tony whispered as he gripped Sirius' arm to stop the man from running out of the room.

They watched as Ginny asked her father who Hagrid was carrying before trying to run to the boy she saw as a brother and best friend only to be pulled back by Arthur. They watched as Neville's expression grew hard, McGonagall scream and Hermione and Ron shout out in pain and disbelief.

"Harry Potter is dead!"

They watched as Voldemort gave his speech, as the Malfoy's tried to get Draco to walk over to them but he shook his head and raised his chin stubbornly- staying where he was. And they watched as a heartbroken Neville limped forward, clutching the sorting hat, and as he made his speech.

Tony and Sirius were barely stopping themselves from collapsing from grief. Everyone else just stayed quiet. Even Fury looked on in grief at what those children were going through.

When Neville finished his speech he yanked a sword out of the hat and ran forward. Two things happened at that moment. Hagrid dropped Harry and Neville was flung backwards.

Tony stood up suddenly, Sirius following him just a second behind as they watched Harry, who was very much alive. They sat back down, relief and happiness radiating from them as they all watched the battle start. Pepper was crying all over again and everyone looked a little less stressed.

It was an intense battle filled with more death and explosions that ended with Neville killing Nagini and Voldemort and Harry firing off green and red spells in the middle of it all.

And finally. They watched as Voldemort blew away in the wind like a pile of ashes.

The remainder of the Death Eater's fled, Harry and Neville ran at each other and met in a kiss- Neville physically lifting Harry's smaller body from the ground in order to hold him- as their friends surrounded them.

They'd won.
