Author's Note & Disclaimer:

This will be a Harry Potter and Ultimate Spider-Man X-over Fanfic. As this is my first fanfic, I would appreciate helpful advice. Not a fan of flames, if you post them, they will be ignored. For timeline purposes, this story begins at the end of Order of the Phoenix for HP and right after the Clone Saga for Spidey. This story will feature a number of other characters from the Marvel Universe.

Major themes: Power Swap, Castling, And Cross-genre romance. Pairings are HP/GS, PP/HG. A couple other ideas in the works for pairings, but haven't decided fully, so feel free to argue the merits of one or suggest one.

I of course own neither Harry Potter nor Spider-man and their associates. The plot changes are mine, but that's about it.

Deep in the bowels of the ministry of magic, below the streets of London, lies the veil of death.

It's origins are lost to the failed bureaucracy of the department of mysteries. All that is known is that once someone goes through the portal, they never return.

Sirius black, like all other citizens of magical Britain, expected his death as he fell through the veil.

What he did not expect was to be offered a cup of tea.

He found himself lying on his back on a very fine oriental rug, looking up at a tall goateed man offering him the aforementioned tea.

"Another exile from England. It's been quite awhile since we had the pleasure. Tea?"

Sirius sat up quickly and instantly regretted it as his head began pounding.

"Shouldn't have done that. You've had quite an ordeal."

Sirius slowly dragged himself against a nearby sofa.

"Am I dead?" He asked of his unknown host.

"Afraid not." The man replied. "You've been banished from England."

Confusion began to take a firm grip upon him. He frantically scanned the ornate room for anything familiar. His eyes settled on a series of runes on the wall.

"You're a wizard!" He gasped.

"Not quite. I am Doctor Stephen Strange, Sorcerer Supreme of planet Earth. And who might you be?"

Sirius's head had begun to clear, so he pulled himself up onto the couch.

"Sirius Black."

Doctor Strange smiled.

"Ah, the infamous Sirius Black. I am pleased to meet you. Are you ready for your tea now?"

"Yes, thank you." Sirius said as he gratefully took the cup.

Doctor Strange waited until Sirius had swallowed his tea before he continued.

Doctor Strange pulled a file off of his desk and began leafing through it.

"Now Mr. Black, onto business. Per the terms of the archway of exile, your title, property, and financial assets have been seized by the British ministry of magic. With the exception of 300 galleons which have been changed into $2,210 US dollars. That and the clothes you are wearing make up the entirety of your earthly possessions."

Sirius nearly dropped his tea as he stared at the Doctor dumbfounded. He unconsciously reached for his wand, only to find it absent from his pocket.

"Where is.."

The Doctor cut him off.

"I'm afraid that as part of your exile, your wand has been taken and snapped."

Sirius suddenly took on a very stern expression.

"Ok, stop right there. Stop processing me. I need you to stop and answer some questions for me."

Doctor Strange nodded and took a seat across from Sirius.

"Fire away. I shall answer to the best of my ability."

Sirius took a deep breath.

"Ok, firstly, where am I?"

"You are on the Island of Manhattan, in the city and state of New York, the country of the United States of America."

Sirius smirked.

"I've been exiled to the colonies?"

Doctor Strange returned his smirk.

"They haven't been called that in a long time, but yes. Before Europe colonized this land, it was a penal colony for bad wizards."

Sirius resisted the urge to roll his eyes.

"Thanks for the history lesson. Now what about my godson?"

"Who is your godson?"

"Harry Potter."

Doctor Strange experienced something he was not used to. The feeling of being dumbfounded. The Master of Magic was used to causing the feeling in others, not experiencing the feeling himself.

"Wait... Harry Potter, The Boy Who Lived, is your godson? The boy whose parents you killed?"

Sirius's expression became very stern.

"I did not kill James and Lily. Nor did I betray them."

Curiosity got the better of Stephen Strange. He reached over to his desk and retrieved a small crystal orb. He handed it over to Sirius.

"Say that again please."

"I did not kill or betray James and Lily Potter, my friends and parents of my godson Harry Potter. I also did not kill the thirteen muggles when I confronted their real betrayer, Peter Pettigrew."

Seriously nearly spat out the last name in his tirade.

Doctor Strange watched the crystal carefully as Sirius spoke.

"I believe you." He said taking the orb back from Sirius.

"Why?"

Strange smiled.

"You were holding an orb of truth. If you lied it would have turned black."

Sirius nodded.

"A useful tool. Wish we had one back home. Now what about Harry?"

Doctor Strange walked over to a stack of newspapers.

"I admit that I don't keep up with the British news, but I do have a subscription to the Daily Prophet. Read for yourself." He said passing the top paper over to Sirius.

HE WHO MUST NOT BE NAMED LIVES!

Exclusive story by Rita Skeeter

Sirius quickly scanned the page and let go a sigh of relief. Harry and his friends had survived. He was actually rather amused reading his obituary.

"Good news I hope." Remarked Doctor Strange.

Sirius nodded. "Yes, Harry is alive, and everyone thinks I'm dead."

He folded the newspaper and smiled softly.

"Thank you."

Doctor Strange returned the smile.

"You are welcome."

"So what happens next? Can I just go back to the fight?"

Doctor Strange shook his head.

"I'm afraid not. The Archway of Exile represents a powerful banishment curse. You cannot step foot on British soil again for the rest of your life."

"Well, can I atleast contact Harry and let him know I'm alright?"

Again, a shake of the head.

"No, the curse re-directs all communication away from the country. All phone calls would disconnect, all letters would return to sender, even E-mails fail to penetrate the seclusion."

Sirius stood up and began pacing the room.

"There's got to be something! Is there any way to get word to him about me?"

Doctor Strange thought for a minute.

"No, but it is possible to bring him here."

Sirius's eyes went wide.

"How?"

Doctor Strange walked back over to his desk and pulled out a notepad and a pencil.

"If Harry has relatives outside of England then they can contact him. Give me a moment to divine their name."

Doctor Strange's eyes glazed over as he began writing. His pencil whirled with activity for a moment then stopped abruptly.

Doctor Strange held his head for a moment and passed the paper to Sirius.

"Here."

Sirius read the page with more than a little confusion.

"Lily had a half sister?"

Doctor Strange nodded solemnly.

"Yes, although she apparently suffered a tragedy of her own. But her son lives, and I in fact know this boy."

Excitement rolled across Sirius as he embraced the Sorcerer Supreme.

"You know him? Is he like us?"

Strange shook his head.

"No, not like us, but quite unique in his own way."

"I've got to meet him!"

Strange finally nodded.

"Yes, I think that could be arranged. Both boys have lost so much. They could use the comfort of family."
