Chapter One "Harry and the Black Crow"

Ron Weasley, Hermione Granger and the rest of the Hogwarts student population awaited eagerly at the name that would represent them in the Triwizard Tournament. The flames of the impartial selector of the school representative lit up. Sparks began to fly. A tongue of flame shot into the air. A charred piece of parchment fluttered out of the goblet of fire. Dumbledore caught the piece of parchment and held it at arm's length, so that he could read it by the light of the flames, which had turned back to blue-white.

"The champion for Hogwarts," Dumbledore read in a strong and clear voice, "will be…" His eyes widened for a moment and regained his previous composure that was so quick that many didn't notice it. He paused for a moment to think, but the observing Hogwarts staff and students seemed to believe that Dumbledore was drumming up the attention. The Hogwarts Headmaster took a breath and made his decision. "…Goes to Harry Potter!"

"Harry Potter? Who is that? I don't remember any Potters currently attending our school. Do you recall anyone with that surname, Mione?" Ron asked his closest friend.

"Who knows? Hogwarts is a very big school. We don't know every student. There might be a Potter, likely amongst the new First years." Hermione replied as she searched excellent memories. "Wait, I think the surname seems familiar to me now. Isn't that the surname of Married Saviors, James and Lily Potter?"

"You mean the vanquishers of You-Know-Who?" Inquired Ron as he tried to recall specific details about the day that the dreaded Dark Lord was defeated.

Hermione nodded. "That's right." Her brow raised as she recalled a particular piece of fascinating information. "Weren't there rumors the Potters had a baby, and it had been a reason why they had fought so fiercely against the Dark Lord instead of running."

"What…" Ron's eyes brightened as the half-forgotten memory surfaced. "I think that particular aspect of the story regarding how James and Lily Potter fought to save their baby was just romanticized. To make the story more interesting, or maybe-"

"Propaganda," Hermione interrupted. "Yes, you do have a good point." She stared at Ron and asked, "Where did the naive and simpleminded hero that saved me during my First Years from a troll go?"

"Hahaha… funny, Mione." Ron chuckled. "Anyone would change after hanging out with one of the most brilliant and intelligent students in Hogwarts for several years."

Hermione had been about to respond when her eyes widened in shock at the sight of a portal appearing. There was one fairly tall and athletic man running from what seemed like a group of pursuers. The man seemed to be suffering all manner of injuries that one might see from a war. He stumbled into the great hall and the portal behind him closed.

Screams filled the hallway as the man dropped onto the floor, spilling an alarming amount of blood. It was so much that Hermione thought the man was likely dead.

"Students please vacate the premise immediately!" Dumbledore roared.

Some students seemed to be too shocked to even react while others were screaming or covering their eyes. The teachers were the first to respond properly as they started to coordinate an evacuation of the hall. Ron and Hermione soon joined the vast group of students that were escorted out.

"Hey, Mione? Was it just me or did that man from the portal share a strong resemblance to James and Lily Potter?" Ron asked as he frowned.

"I think that was a coincidence." Hermione replied.

"A coincidence?" Ron repeated incredulously. "Someone that might be the son of James and Lily Potter just so happens to appear after Dumbledore announces the name, Harry Potter?"

- O -

"How is the young man doing, Poppy?" Dumbledore asked as he entered the infirmary after dealing with the evacuation of the students and the teachers that had assailed him for answers about what had happened.

"The young man should be dead, Albus." Matron Poppy Pomfrey replied bluntly.

"Dead?" Dumbledore repeated. "Poppy, I see a breathing and sleeping young man before me."

"The young man suffered from wounds caused by weapons that were enchanted, contained or coated with substances that either prevented or greatly hindered healing magic. Even the most powerful healing magic I know and are capable of were only able to provide first aid. He is alive because of his body's own self-healing abilities and the medicines he carried." Pomfrey replied.

Dumbledore looked at the table beside the unconscious young man containing what liquid and solid matter that Pomfrey had likely extracted from her patient's body while she had been treating him. The elder wizard wondered what could have stopped such a skilled and experienced healer's magic but he frowned as he started to recognize the extracted liquid and solids.

"Please show me the medicine you used."

The matron produced a bag and handed it over to Dumbledore as she replied, "This bag belongs to the young man. Inside it contained potent medicine made out of ingredients that I cannot identify or shouldn't exist anymore as they no longer exist or have gone extinct on Earth. It was these medicines that I was able to treat the young man."

"Hphm." Dumbledore inspected the medicine in the bag with great care. "Could I see the medical report you wrote after treating the young man?"

After being handed the requested papers, Dumbledore quickly got to work comparing what he read with knowledge that few matched with his century-plus age. What he found at first seemed like one or two coincidences. The coincidences started to pile up until his discovery could be counted as coincidences anymore. Dumbledore didn't know how but the young man who had suddenly appeared in the great hall possessed medicine made with ingredients and skills that had been lost to time. The question about where the medicine, who made them and the source of the ingredients were filed away as Dumbledore could always ask the medicine owner after woke up.

What caught his eyes were the injuries inflicted upon the young man.

The skills of the medicine maker and ingredients had been lost in time due to a myriad of factors, but that was completely different from what had caused the young man's injuries. The knowledge, skills and material needed to create the various weapons that had wounded the young man had been destroyed thanks to the efforts of countless people and generations that wished to prevent the great destruction and death that magic had once been able to accomplish, which had later been spun into the muggle stories and myth of what they considered 'gods' and magic were capable of.

It was why Voldemort despite his very best wishes couldn't use a powerful magic spell or magical weapon on the scale of the Muggles' most powerful weapons such as a nuclear weapon against his enemies. Powerful magical weapons and spells of such magnitude no longer existed. The only things left were records of what magic was once able to do when used for war in the ancient past.

"Pomfrey, I will have to ask that you never reveal the contents of the medical report in my hands," said Dumbledore in a serious tone. "What you have witnessed are the effects of weapons and magic that should have been eradicated and no longer possible. If news of what had really caused the man's injuries were to leak then Voldemort and his Death Eaters are likely the very last thing to be worried about. Dark Art Practitioners from all around the world would love to grab their hands on your patient."

"Understood." Pomfrey nodded. "Albus, I wanted to know. Did James's and Lily's son really die as you officially proclaimed?" She asked while looking at her unconscious patient. "Because the young man looks like James did when he was young and has Lily's eyes."

"The body of Harry Potter was never found. One of my spies, who is amongst Voldemort's most trusted followers, told me the baby was never found." Dumbledore replied. "But I think we might have discovered our missing person."

"Just because my patient looks like James and Lily or that he just happened to appear after you called out Hogwarts' champion?"

"You might not know this but the Goblet of Fire is capable of summoning the selected candidate. This has been shown in the past Triwizard Tournaments, but it happens so rarely that people forget about it." Dumbledore explained and a quick glance at the nearby clock told him it was time for one of his scheduled meetings. "Please alert me as soon as the young man wakes up."

- O -

I groaned in pain as my eyes opened. I looked around and was surprised by what I found. The place I had been expecting was the afterlife and since I was never a believer of the countless gods in existence, my soul should have entered the cycle of reincarnation. Still, I sighed in relief. Whichever medical facility I was in meant that I was still alive.

"How are you feeling, young man?" A middle-aged woman asked as she slowly walked to my side.

"Banged up a bit," I replied honestly. "Still, I would prefer that over being dead. Thank you for saving my life."

"I am happy to help anyone that is hurt." The middle-aged woman smiled. "You seem to be under the wrong assumption that I healed all your injuries. I did provide emergency first-aid to stop you from dying from blood loss and keeping your organs functioning but it was your own self-healing and the medicines in your spatial bag that saved you."

If it was any other time that you had rampaged through my belongings then I would have given you a taste of my fist. I thought to myself as I smiled. "I still have to thank you as even without my own self-healing or medicine I would have no doubt died."

"You don't need to thank me. I was doing my job and pleased that I managed to save another life." She smiled back. "My name is Poppy Pomfrey. What is your name, young man?"

"Harry Potter," I replied and the newly introduced woman stumbled back as if she had been hit. "Is there something wrong, Madam Pomfrey?"

"Dear Merlin…" Pomfrey murmured in disbelief.

Merlin? So, this place worships Merlin. I noted happily. The believers of Merlin often were separated into two groups. Those that were druids and other nature-based mages believers and the regular mortal worshippers. If Pomfrey was from either group then I would be able to get along with them without much problem if past experience was anything to go by.

After recovering her composure, Pomfrey asked, "May I take a sample of your blood to confirm if you are related to someone I know?"

"Sure, no problem." I nodded and became curious at the possibility that I had met someone. It was the first time I had found anything about my birth parents since the Goddess Morrigan had intervened to save my life and drop me off at the orphanage that had raised me. "May I ask where I am?"

"You're currently in the infirmary at Hogwarts."

"Hogwarts," I repeated slowly. "You mean Hogwarts School of Wizardry and Witchcraft on Earth?"

"Yes, that is current." Pomfrey nodded. "Where are you asking if Hogwarts is on Earth? You make it sound like you're from another planet. There is no other planet besides Earth that is habitable by humans after all."

"Earth as in the planet that may be also known as Gaia or Terra, amongst various other names to name the planet." I continued to inquiry in disbelief as all contact with Earth had been lost centuries ago and only the gods were said to have any ability to communicate with the planet in any real manner.

While my mind was still processing the fact that I might be on Earth, my mind finally came to why I hadn't been able to find anything despite travelling many places to why I couldn't find any clues to my parents. How was I supposed to gain information about my parents in a place that even the gods have a difficult time reaching ever since the Earth's world barriers that influenced interplanar communication and travel had been activated.

Now I wondered why the Goddess Morrigan had been so interested in my baby self. Even for a god, it was said that reaching Earth was an exhausting task. Gods might be Transcendents with incredibly powerful abilities outside the imaginations of mortals, but they still had the same mindset of mortals. Only if someone that was incredibly important to the gods would warrant exhausting their powers to reach into the isolated Earth.

The only thing I could think of warranting the personal attention and intervention of a powerful goddess such as Morrigan would normally be: if I was one of her descendants, an incredible devout believer or a possible candidate to be given the honor of being an avatar of a god. I clearly didn't meet the first two options, and the last one also seemed unlikely as Morrigan had never chosen any interest afterwards in me after saving my life as a baby. So, it likely meant I had been one of the instances where a mortal caught a god's attention before being forgotten about as something else caught the god's focus.

Whatever the case, the goddess Morrigan had saved my life. I made a mental note to visit one of the Goddess Morrigan's shrines to offer a prayer of gratitude and make a generous donation to the shrine.

I was surprised by the appearance of a black crow, almost as if answering my thoughts. It looked at me with interest. I nearly gasped in shock and got out of the medical bed in great haste. Irish happened to be one of the many languages I had learned during my mercenary days on the CrossRoads so I tried to speak in the politest manner I could remember in the Irish tongue.

"Oh, great Morrigan, Goddess of War and Fate, I thank thee for saving my life as a baby." I prayed relevantly as I conjured up a simple dagger and made a shallow cut to my hand. "Please accept this blood as my oath to protect your followers and shrines."

The black crow flapped its wing and landed on my arm before tasting my blood. It cawed happily in response. I felt an ancient and wise voice echo in my mind.

"Harry James Potter, I saved you because of your role in a great prophecy that would affect the British Isles." It explained. "In return for saving your life, I would ask that you revive the withered faith that once flourished on these lands that are your homeland."

"I would be honored to help your faith spread again." I solemnly vowed.

The black crow looked at me with delight and cawed happily once more before it opened its wing and disappeared out of the window.

"What in Merlin's name was that!?" A shocked Pomfrey shouted as she pointed at the window the black crow had flown out of.

"Please don't use the name of a god so lightly. I doubt Merlin would approve of you using his name in such a manner." I advised as I recalled several horrible experiences of arrogant mortals not believing that invoking a god's name was a serious matter. "You seem to not know this but gods exist and are very prideful beings. Bringing the wrath of a god is not a trivial matter."

"Gods don't exist. They are fictional beings made up to explain things beyond the imaginations of muggles or to describe extremely powerful wizards and witches." Someone spoke up as they entered the room. "

He was tall, thin, and very old, judging by the silver of his hair and beard, which were both long enough to tuck into his belt. He was wearing long robes, a purple cloak that swept the ground, and high-heeled, buckled boots. His blue eyes were light, bright, and sparkling behind half-moon spectacles and his nose was very long and crooked, as though it had been broken at least twice.

I was about to warn the elder when I was beaten to the punch. The black crow quickly returned but so quickly that it might have been teleportation to most mortals, and I barely caught a blur register in my superhuman vision.

"Albus Percival Wulfric Brian Dumbledore," the ancient and powerful voice boomed, "gods do exist and we are not someone to insult lightly. Earth, Herself, might have banished us from this planet for our past mistakes, but our eyes and ears are still here. The mortals, or Muggles that you call them, can be forgiven thanks to the manipulation of wizards and witches to keep them ignorant of magic but the same cannot be said for your kind, Dumbledore. Someone knowledgeable as you shouldn't dismiss our existence. Continue to do so and I will make you regret it, even if I must pay the price for breaking Earth's rule restricting us, gods."

The powerful blast of raw mana sent me tumbling onto the ground. I had never experienced it for myself, but it seemed like the stories about angering a god, even if it was an extension of their presence such as the black crow before me, wasn't a laughing matter. The black crow likely contained the smallest fraction of Morrigan's might, but it was beyond even the most powerful creatures, which included legendary dragons I had seen in passing, to shame.

Poor Pomfrey had it the worst. She outright fainted and dropped onto the ground like a corpse. It was only the shallow breathing and movement of her chest I spotted with my superhuman senses or the mana fluctuations coming from her that I knew she was still alive.

Dumbledore seemed slightly rattled if his serious expression I saw was anything to go by, but the fact that he was still stubbornly standing and glaring at the black crow spoke of his courage, or arrogance. I shook my head. Gods might have their powers restricted on the mortal planes but the resources and influence under their disposal would make only the most powerful mortals likely those in the process of becoming Transcendent/god themselves did not fear for their lives. Dumbledore clearly was far from becoming a Transcendent even if I could gauge exactly how powerful he was.

"You may be the most powerful Animagus I know of, but you still shouldn't pretend to be a goddess when gods don't exist, if they had existed at all that is." Dumbledore refuted defiantly.

"You have balls of steel…" I muttered quietly before rushing to Dumbledore's side and bowed to the black crow. "Please forgive this man, oh great goddess. He is not worth the backlash in defying the rules regarding the gods, especially on this planet that has strong feelings regarding gods influencing mortal matters."

"You are certainly right about the backlash." The black crow grudgingly nodded. "I spare your life, Dumbledore, on account of Harry and his mother's devout beliefs in me." It cawed before flying out the window.

I sighed in relief and turned around to stare into Dumbledore's eyes. "Are you insane!? Denying the existence of a god after witnessing it for yourself. And then you proceeded to personally insult the goddess, Morrigan. If you have a death wish please do it to someone else that doesn't have hundreds of innocent bystanders nearby. If the goddess had been angered there likely would have been a mile wide crater where you once stood!"

Omake "Albert Einstein"

"So, you're telling me Albert Einstein was a legendary scientist that lived on Earth?" I asked in disbelief.

"Yep!" Hermione nodded.

I was starting to have a headache. The person I knew was not a mortal, but a god known as Einstein, the God of Nuclear Magic. In terms of the lifespans of gods that were immortals, Einstein was a newborn baby of less than a century old but that didn't mean Einstein was weak. The God Einstein's power and influence out-matched many gods that had existed for thousands of years. This had been a result of the new field of magic called Nuclear Magic. So strong were the powers available to properly trained Nuclear Mages that they were amongst the most dangerous beings beneath the gods. Afterall, few creatures could survive the explosion of miniature stars.

"Thank god the Einstein Accords or the mortal planes would cease to exist from the endless wars." I sighed in relief.

"What are the Einstein Accords?" Hermione asked as she started taking notes.

"A divine pact forced upon Einstein by the other gods in fear of the powers available to Nuclear Magic users. Only devoted believers of Einstein can use nuclear magic and made Einstein personally responsible for atrocities of nuclear magic users. Another part was that it forbade Nuclear Magic from being used in any conflicts save for power generation and scientific research." I explained what was considered as common knowledge outside of Earth.

"So basically, like the Treaty on the Non-Proliferation of Nuclear Weapons."

I nodded to Hermione. "In short summary, yes. But this is a magical contract of the highest caliber that can kill gods if they break the contract." I paused for a moment. "Is there any other human on Earth whose research can produce powerful weapons like Einstein?"

"Well, there is muggle physicist Paul Dirac, considered the father of antimatter."

I groaned and didn't feel well anymore. It was one thing to learn that Einstein had been a former Earth inhabitant that had reincarnated in another mortal plane who would eventually become a god, but another similar case was too much.

Why did I think Earth was a backwater and isolated plane that has nothing to offer to the CrossRoads!?

Was this good, bad or meh? Please tell me what you think. I accept all criticism as long as it is no flaming.
