"How in the bloody hell did we get to the other side of the planet?!" Sirius looked around stunned.

"All my Sanctums have a focal point and they all connect. Making travel between very easy."

"That is brilliant." Sirius was starting to like this magic. "Makes port-keys look like a bad prank."

Even Remus was in awe. Across an ocean in seconds. It was impressive.

"I'm glad you're entertained. I hope you can see the implications." Strange moved back into the Sanctum with the others following.

"You want Sirius and Harry to live in the States," Remus noted.

"Exactly. With my travel, you can come and go from England and the Ministry without anyone the wiser about your location."

"Promising but even here Harry's story is bound to be the talk of the magical community," Sirius said.

"That is true. Your magical group is prevalent here as well but the rules are stricter."

"Then the Ministry?"

"The Statue here is heavily enforced. They are very hard on anyone who risks its beaches. Be it Pureblood or Newblood."

"Newblood?"

"I find the term Muggle or Muggleborn unsavory."

"Lily had the same belief," Remus remembered.

"She sounds like someone I would have enjoyed conversing with." 

"She was the brightest witch of her year. And a force to be reckoned with in her own right. James spent years trying to win her over." Sirius smirked as he looked at Harry.

"Sirius. I have some friends here who can help you find a good place for you to live. Here no one will think to look for you. With my Sanctum access, you will be able to come and go from London with ease. Everyone will believe you still reside there."

"And Harry will grow up away for all the attention the bloody name will bring him." Sirius agreed. "I'll have to go back to the Goblins to move some gold here."

"I'll take care of all the legal issues for the non-magical side." Strange waved his hand and stacks of documents landed. "There."

"I'll never stop loving magic," Sirius smirked. "What able the MACUSA?"

"You and I will have words with the President. I'll stress the need to keep Harry's identity here quiet. Luckily he's in the city and my organization has had talks with him in the past. He'll comply."

"I would have bloody killed to have you in the war. The whole thing could have been over in a day."

"Unfortunately my priorities are normally for a bigger scale. Even now I know some are wondering why I got involved."

"Why did you?" Remus asked. "I'm grateful for helping Harry and Sirius but I can't help but wonder what's in this for you?"

"Why? I found a baby on a doorstep. I'm not as heartless as some to ignore that." Strange sat as a chair appeared. "Your world is slowly becoming more of a danger to the rest of the planet than your leaders wish to address. First Grindelwald. Now Voldermort. And still, nothing was learned from them. After the threat is over NOTHING changes. Frankly, I am over it. She had a higher tolerance for it than I do. She was adamant you be able to govern yourselves. I see that is not the best way."

"And Harry? What do you have planned for him?" Sirius looked at the sleeping toddler.

"That's for him to decide. I only want to make sure he has a chance to make the choice." He rubbed his face. "Mr. Black. Mr. Lupin. Let me show you Harry's life if I hadn't done what I did."

Suddenly the room changed. All around them are images and voices. 

Boy!!

Drunks who died in a car crash!

A large man threw the boy into a cupboard under the stairs.

The frying pan missing the boy's head.

A fat child unwrapping a large pile of gifts as a skinny Harry looked feeling hungry.

The show-stopped.

"Those are some of the best. There would be others far worse."

Sirius and Remus were stunned. Remus looked sick. Sirius looked murderous. He knew Petunia hated magic but this.

"I'm going to kill those monsters," Sirius said in a cold voice. 

"No, you're not. That was what could have been. Not what is. They haven't done anything wrong."

"The fact they would even do that is enough reason for me!" 

"Yes go kill an innocent family. Live up to your family's name." Strange hit him where it hurt.

Sirius went from angry to sick-looking. Being compared to his family always left a sick feeling in his stomach.

"Padfoot. That didn't happen. Harry's right here and safe." Remus reminded him in a calm voice. "How could Dumbledore allow that?"

"Because he never checked. He knew Harry would suffer but to him, the wards were worth any price. And he had a promise to keep. He said he would protect the Dursleys and used Harry to fulfill his oath. Harry 'may' have been safe from Voldemort in that house but it is frighteningly easy to find a way around that protection." 

"He didn't put much effort into keeping Harry safe did he?" Sirius asked.

"Underwhelming at best. Even without my magic, I could have easily gotten to Harry and so could anyone else. A Death Eater could easily pay a non-magical criminal to enter the house and take Harry. Dumbledore would have been none the wiser."

Remus felt sick. Was it that easy? Some members of the dark lords forced were very rich. I can't believe he made such a mistake.

"Harry has a future full of potential. He will need you to help him fulfill it."

"What future?"

"One tied to Voldemort."

"How? I know the bastard is still around but he's harmless for now."

"There's something I don't quite understand between the two but Voldemort is obsessed with Harry for more than his defeat. They will meet again. Harry will be ready if you are."

Sirius let that realization wash over him. Harry's life wasn't just in his hand. His future was too. "If it gets Harry to live a long happy life. I'll do anything you want."

"Good. Get some rest. We have a lot to do."


The next day after Remus and Sirus flipped over who would change Harry, the three were sitting at a table trying to feed the boy.

"Come on Harry eat up." Sirius.

"Mum." The toddler said looking around.

 Both men looked uneasy. They didn’t know how to tell a child that his parents weren't coming back.

"Daddy and Mommy are away." Sirius tried. "They love you very much and you'll see them again. One day."

"Pogs." The child said next.

"Prongs. Is with mommy." Remus carefully patted the boy's leg.

"Come on eating up." Sirius tried again.

The back and forth between the three as the adults failed to get Harry to eat.

"Trouble?" Wong smirked from the doorway.

"No. Just a picky Pronglet!" 

Wong came up and looked Harry in the eye. "Eat."

Harry opened his mouth and Sirius gave him the food.

"Brilliant trick." Remus was shocked.

"No trick." Wong shrugged.

"You will make a fabulous mother one day." Strange smirked as he came in.

"Very funny Strange." Wong glared at him. "What did you learn from the stone?"

"A lot. There is a busy day ahead. You will want to go to the Ministry, Mr. Black." He looked at Sirius.

"Just Sirius. What's happening there?"

"Today in a few hours Albus and the Minister will attempt to make the Potter cottage in Godric Hollows a monument."

"Like bloody hell they are! James and Lily are not a tourist attraction."

"I figured that would be your reaction. We'll take care of Harry while you're away."

"How did you know that they were planning that?" Remus asked.

"I put a spell in both the Headmaster's office and the Ministers. It allows me to listen in."

"You're spying on Albus?!"

"Yes. No, I won't apologize for it. That man loves his secrets and shares nothing unless forced."

Remus wanted to argue. It didn't seem right to do that to Dumbledore. 

"We both know Strange is right about Albus and secrets. Frankly, I couldn't care less if he wants to spy on everyone in the Ministry or Dumbledore. The more we know the better." Sirius said.

"So he can spy on us and Harry too?"

"I'm not." Strange answered. He had no reason to.

"Forgive me if someone who puts spells on high rankings officials has me on edge."

"I haven't lied to any of you. Nor will I. Lies and falsehoods don't build trust. And from what I saw we will all have to trust each other."

"What did you see Strange?" Wong asked.

"Something I need to check on before I'm 100% positive. I will explain tonight. I promise." He looked at Remus. "Mr. Lupin can I speak with you? There's a private matter I think you will benefit from."

Remus looked at him confused. "I don't see why not."

"I'll finish feeding Harry and go take care of this."

"Food for thought. They can't make a house a monument if there is no house." Wong said.

"I'll help you with moving your friend's remains if you wish." Strange offered. 

"Thank you but that is a personal matter. I might not be as well connected as some but I have people and ways to get things done." Being wealthy had its perks.

Sirius already had a plan forming. Wong's suggestion gave him a hilarious idea.


Once Harry was full and Remus was comfortable watching him. Sirius left the Sanctum to the Ministry. But first, he stopped at the necessary places to make his plan come into play.

Once he was finished and everything was set he marched through the Ministry with anger radiating off him.

"Who do you think you are?!" He burst down into the Minister's office.

Inside he shocked the assembly of Bagnold, Albus, and some other department officials.

"You will not be making any monument out of that house. I am in charge of all Harry's properties including that cottage. I will not let it become some symbol for ministry posterity.

"Mr. Black." Bagnold started.

'Don't. You didn't even bother to ask me about MY property before you attempted to steal it."

"It wasn't stealing. It was just a suggestion Albus was bringing forth." She was surprised at how fast Sirius heard about it. Albus had only been here for a few minutes before Sirius.

"Sirius you have to see that it would be a benefit to everyone. A symbol of how love can conquer over hate."

"No. That's my final word on this. If you want to have something for them then I suggest giving both James and Lily an Order of Merlins. First Class."

Some of the other officials looked like that wasn't a bad suggestion. One other looked disgusted at the idea.

Sirius saw her. Don't want a muggleborn to be rewarded? Bloody bigots!

"Unfortunately whether you are in charge of the property or not the Ministry can declare it a landmark without your consent." The woman said.

This made Sirius smirk. "Well, it's too bad I've already moved James and Lily's bodies. And I've just authorized the destruction of that house." Sirius looked at his watch. "Twenty minutes ago." He smiled. "By the price, I paid it will be destroyed before this meeting is done."

"You can't do that!"

"I just did." He looked at Bagnold. "You want to honor the Potters you know what to do." 

Albus had disappointment etched on his face at the fact his plan to give the people a symbol was gone but had to push forward.

"Sirius we still need to have a conversation."

"Not right now. This dragonshit you just tried to pull has me in a not-so-pleasant mood. Good day, Albus."

Sirius left the room without looking back.


Remus and Strange sat across from each other in his study.

"I notice you didn't add yourself to living in or around Harry." Strange just went straight to the point.

"I have a reason for not being too close to Harry. Sirius knows them." 

"Because you are a werewolf?" 

Remus was stunned. Both that Strange knew and how it didn't seem to bother him at all. "You knew?"

"Ever since you stepped into this building."

"You didn't cast me out."

"Why would I? You are no threat to anyone until the full moon. And you're a victim of a disease."

"I'm sorry to sound so shocked. I'm just used to a worse reception."

"People will always fear what they don't understand. Especially if they refuse to try to."

"Well, then you understand while I can't live close to them."

"And if I had a solution for your situation?"

"There isn't one. I have had to live with this for years."

"I've heard rumors of a potion in development that could allow a werewolf to maintain his human mind during transformation. It's years out but it would help. However, I have another idea."

Strange got up and opened a portal. "Follow me."

Remus did and found himself in a place very advanced. He wasn't as far behind as a regular wizard but this was technology he had no idea even existed.

A man came down the stairs. He had slightly graying curly hair.

"Stephen." The man said cheerfully. "This is a surprise."

"Dr. Banner." The doctors shook hands. "This is Remus Lupin. Mr. Lupin this is Dr. Bruce Banner."

"Nice to meet you." Bruce offered his hand.

"Same. Thank you." Remus shook.

"Mr. Lupin has a unique illness I was hoping you could assist with."

"Contagious?"

"Only if he bites you."

Bruce laughed but realized Strange wasn't. He was being serious.

"Oh. You mean that. Well, I'll need samples and testing."

"You always going to just break into my building so casually." A new voice said from the elevator.

"Here I was hoping to avoid this conversation." Stephen sighed. "Stark."

"Dr. Rabbit From Hat," Tony replied. He then noticed Remus. "Are you bringing random people off the street here?"

Remus knew he was addressing his torn faded clothing. But he was at a loss of words. Even living in the Wizarding world he still spent a fair amount of time outside it. And he heard of Tony Stark.

"This is Remus Lupin. He's a wizard." Strange said casually.

"You can't go around telling everyone that!"

"Your Statute has no authority over me. Besides these two have had experience with magic in the past." Not your magic but that's a technicality.

"Statute?" Bruce asked.

"Mr. Lupin is from a hidden part of the world. Where magic and normal individuals are separated by laws and secrets. They raring have interaction with my organization either but I'm changing that."

"Nothing surprises me with magic anymore. So removed from society? That explains the robe found in a dumpster. What year are you living in?"

"They are far behind compared to the rest of the world. I hear they even write with quills on parchment." Strange answered.

Tony went wide-eyed. "Centuries behind then. How do you even function?"

"It's not that bad. Besides our magic doesn't work with technology. It causes it to malfunction and sometimes explodes." Remus defended.

"That's another topic I need to discuss on a different day. But for now, the reason we are here today. Mr. Lupin is affected with a disease that forces him to change every full moon."

"A werewolf? A real-life werewolf?!" Tony was intrigued. "This I have to see."

"You don't want that. Trust me." Remus said. A little upset Strange just told two strangers about his personal life.

"I know you don't want to advertise what you are but if anyone can help you it's these two." Strange motioned to Bruce and Tony. "Bruce is one of the most brilliant minds on the planet and Stark is...annoyingly smart as well."

"Coming from the Ph.D. and MD holder who didn't know how to drive a car?" Tony said back. "Anyway, how does this transformation work?"

Remus sighed. "When the moon is full. I can't control it. I became a beast. A danger to everyone."

"Hey someone you can relate to Brucey," Tony smirked.

Bruce glared at him.

"Dr. Banner I believe you may be able to help Mr. Lupin. In more than one way."

"There's no cure. Certainly not one in the muggle world." Remus bowed his head.

"What did you call us Mr. Furry?" Tony eyed him.

"That's their term for non-magical." Strange explained.

"Oh well, that's moronic and insulting." Tony grabbed one of his hidden snacks and began eating.

Remus felt very uncomfortable in the situation right now.

"I can certainly take a look," Bruce spoke up.

"Perhaps science can prevail where magic failed." Strange hoped.

"I can't afford to pay you," Remus said quietly.

"Who said I would charge anything?"

"Why help me? Not to sound rude but I'm a stranger to you?"

"Bruce, because he's a good man with a big heart. Me I'm curious and love a challenge." Tony smirked. "And I have to see this transformation in person."

"I don't think you don't know what it's like to not have control over yourself. To hurt people and not being able to stop it." Remus argued.

Bruce smiled at him. "You might be surprised."


Dumbledore felt like he was banging his head against the wall. 

Nothing he said was able to get Petunia to allow Harry to stay. She refused to even hear him out after his third attempt to explain the power of the wards.

Even worse he couldn't even use any compulsion charms to, at least, make her consider it. No magic would hold on to her. It was like something he had never experienced before. 

Strange no doubt. Ensuring Harry would never go back. Blast that man. Why can't he understand I know best? If Petunia won't allow Harry to live there then the wards won't hold.

He had finally admitted defeat and returned to the castle in a very somber mood.

As he sat at his desk he pondered all that had happened in a matter of days. What should be a time for rebuilding was a time of uncertainty. 

Perhaps the idea of the house becoming a monument was poorly made. Now Sirius is even more upset at me. The Order of Merlin for both James and Lily was something I might have agreed with but that would cause some undesirable consequences.

Lily being a muggleborn would cause some discomfort with some of the traditional purebloods. I fully believe she deserves it but that was one situation that could have been avoided with the monument. 

Albus sighed at the headache forming. 


After his visit with the Ministry Sirius had one more detail to work out before his day was over. 

Strange had helped him with finding a realtor who said they had found a perfect place for them. Strange had already informed someone a few days ago, unknown to Sirius, and set up a meeting. Strange had already planned for them to move to the States not long after he took them into his Sanctum.

Normally Sirius wouldn't like someone planning out HIS life but this was a minor thing. Strange was very well prepared. Plus Harry would be safe and happy here.

"Man moves fast." Sirius was starting to like this doctor.

Since money wasn't an issue that made the search easier. Being the head of the house did have some perks. And having someone who could open portals anywhere was a big help.

All the properties listed were interesting but the one he was looking at next to a lake was the best. 

"It's perfect." Sirius looked over the cabin. "Harry will love it here."

A few long talks with the realtor and Sirius put the buy in motion. He had a house. They had a house.


Stephen was watching Harry play with his toys intently. This was what would decide his next course of action.

"Stephen. Fascinated with a child's playtime now?" Wong came up next to him.

"Only if what I saw comes to be."

"Don't try to be cryptic with me. You come off pompous." 

Strange smiled at that. "That boy has the potential to either be the best thing to happen to this backwater world or its downfall."

"You've seen that?"

"1,084,170 different outcomes. What happens next will decide what path I have to help him down." Guide not manipulate. I will not be Dumbledore.

Both kept their eyes on Harry. He giggled as he made a mess with some blocks. Then the blocks began rebuilding themselves.

Harry's hands were glowing with a red hue as he clapped them together.

Wong went wide-eyed and paled. "Strange what is that?!"

Stephen kept his eyes on Harry. "Chaos."
