Chapter 1 - The Empress and the Prince

Kadriorg Palace, Tallinn, Estonia

The year was 1993, and the month of August had just begun. This date was of great interest for the woman resting inside the palace, for she knew that soon enough, her grandson would be returned to her at last. For her, it was perhaps the most joyous moment of the last years, and only surpassed by the return of her long lost daughter. This woman was Maria Anna, the sovereign ruler of the Russian Empire and of the United Kingdom of Portugal, Africa and the Algarves, and the Queen Dowager of Nicaea.

Her husband Alexandros, the King of Nicaea, had died several years ago, and she had been left with the leadership of the Regency Council of the Roman Empire, a task that while seemingly difficult came with a rather agreeable set of privileges. It had been unfortunate that he had been unable to meet his daughter once more, having died before she had retuned.

When Maria Theresa, her daughter, had been kidnapped by those damned revolutionaries there had been nothing she could do, but to hope and pray for her survival and safety. Yet when she discovered that her daughter had been in Britain, and that she had discovered her true heritage on her own, she felt great joy and pride. But now, history seemingly repeated itself, and after the murder of her daughter and son-in-law, their son was also kept away from his true family, or at least what remained of it.

Maria Anna was inside the palace's small library, the old woman sitting on an armchair reading a book while warmed by a blanket. Despite being resilient, the woman's age had made her a bit sensitive to the temperature, and on this cold night it was the only way for her to feel any warmth inside the library. She was fully immersed in the book, old eyes reading and memorizing the words, ignoring the silent surroundings. At least until she heard the door of the library being opened and the footsteps of someone approaching her.

The newcomer went towards the armchair, and when he was close enough, the man knelt.

"Your Most Faithful Majesty, I bring news to you." He said, "From the council."

Maria turned towards the man, carefully placing the book on her lap.

"What do they want?"

"The council wishes to inform you that they have everything prepared for His Highness's recovery, and that if you so wish, they shall act as soon as possible," informed the man.

The old monarch kept her face clear of any expression, but inside she smiled.

"Inform the council that they are not to act rashly. Have them wait for the correct moment to act, and when the opportunity presents itself… Also, tell them that my grandson is to be brought to the Palace of Nicaea, as that is where he will be residing as of his arrival," she informed. "I will travel there tomorrow and I want them to make sure that all of his possessions are brought as well."

The man nodded.

"It shall be done, Your Majesty."

"You may go then."

The man rose and left the library, but not before bowing to the Empress-Queen, leaving the old witch with her books and the warm blanket. But with her was also a profound sense of joy, and she could not help but smile slightly.

Diagon Alley, London, England (U.K.)

It had been two days since Harry had ran away from the Dursleys and was rescued by the Knight Bus. The events following his arrival at the Leaky Cauldron had been rather strange, as Harry was not expecting to find the Minister for Magic inside the pub. The fact that the Minister seemingly thought that the escaped convict Sirius Black was after him was alarming to Harry, but the young teen was not stupid enough to go into the streets of muggle London after the warning. Since Black was one of Voldemort's followers, it was clear that he would possibly seek to avenge his fallen master. And if what Fudge had said was right, then the years in Azkaban had perhaps warped Black's mind even more, meaning he was possibly even more unstable than he had been before was captured.

Deciding that spending all the time walking around his room was a waste, Harry decided to visit Gringotts and withdraw a moderate amount of money, enough that he could buy a few things that would allow him to enjoy better his time in Diagon Alley before returning to Hogwarts. One of his stops was Flourish and Blotts, where he discovered a rather neglected section with books of foreign origin, but which had been translated into English. Amongst these books was a collection called the Encyclopædia Veneficia, apparently published in 1890 and written by a Prussian scholar called Ernst Dietrich.

Harry realized that there were three volumes, and upon looking at the price he noticed that they were rather cheap, especially for Flourish and Blotts standards. Could it be that the owner of the shop wanted to get rid of them? In any case, it was a deal that Harry could not simply ignore, and he would not help but feel as if he had to possess that collection. Collecting them from the shelf, Harry went towards the shopkeeper to pay for them went to pay them, noticing that the man looked at him strangely, almost as if he was buying a fairy tale book. Harry decided to ignore the man, and simply paid the books, before returning to the Leaky Cauldron.

Once inside his room, Harry sat on the bed, and began to read bits from the three books. The more he read, the more he realized how much information the books had, and despite being clearly outdated, having been written in the 19th century, the three volumes had a lot of information that was not just in text but in images as well, such as using rather detailed drawings to show the fashion used by certain wizard cultures across the centuries and even a section dedicated to heraldry, amongst other things.

'This must have been the work of a lifetime,' thought Harry as he continued to read.

Eventually, he began to notice that many of the topics mentioned and at least directed the reader to the Roman Empire section of the encyclopaedia. Realizing that he was learning more by reading these three books than by attending the History of Magic classes, Harry opened the third volume intent on finding why the Roman Empire was receiving so much attention. And as he reached the page where the topic was, Harry's eyes widened in surprise, for the article was at least six pages long. But still, Harry's curiosity got ahead of him, and so he began to read the article.

The Roman Empire

The successor of the Roman Republic, the entity known as the Roman Empire (Imperium Romanum in Latin, and Basileía Rhōmaíōn in Greek), was for all intents and purposes founded in the year of 27 AD, when the Senate of the Republic gave Gaius Octavius the title of Princeps Senatus with proconsular imperium, thus beginning the period of history known today as the Principate, characterized by a clear attempt at maintaining republican traditions and denying the monarchical situation that the Empire had fell into. It was followed by the period known as the Dominate, started by Emperor Diocletian who declined the use of Princeps and became the first emperor to use the title of Dominus (translated as either master or lord). With the passage of time, this political system would evolve into what may be identified as an Absolute monarchy in the eastern half of the Roman Empire, and would later engulf the entire community of wizards with the Treaty of Ravenna in 801, presided over by Empress Irene due to the machinations of Leo III, the muggle Pope, which led into the eventual sovereignty of the Roman Empire over the wizarding community of the known world.

The capital of the Empire changed places several times, from Rome to Ravenna in the Western Empire, and from Rome to Constantinople in the Eastern Empire. (…) While the Ottoman Turks captured the muggle Constantinople, the magical Constantinople was not affected by the conflict, due to its location inside the Bosphorus Cavern. (…)The Roman Empire was among the most powerful economic, cultural, political and military forces in the world of its time, and still is today. It was dissolved in the muggle world in 476 AD (Western Empire) and in 1453 AD (Eastern Empire).

Today, the authority of the Roman Empire is challenged by the International Confederation of Wizards, which was founded after the attempted coup by Pierre Bonaccord, at the time a member of the Regency Council of the Empire. His family connections led to him being assisted by the Ministry of Magic of Great Britain and Ireland and the government of the northern half of France. The public opinion of Bonaccord led to a civil war in France, which ended with the establishment of the Northern French Republic, which became a founding member of the International Confederation (at the time known only as the Franco-British Confederation), and the reestablishment of the Kingdom of Aquitaine, which remained under Roman rule. (…) Two of the main points of the conflict comes from the views on blood purity and religion, the former being regarded with great importance in the International Confederation and having little impact in the Empire, while the latter is an issue which affects the two factions in an almost equal way.

While in the Empire the known religion is the Perennial worship, assisted by many cults, some of which have existed before the advent of Christianity, the common religious practice in nations inside the Confederation is the revived cult of the Celtic tribes prior to the Roman conquests. It's far more famous in Britain than in the other territories of the Confederation, and it is known to be practices by the older families, which self-identify as "pure-bloods".


As of today, only the United Kingdom of Great Britain and Ireland, the Northern French Republic, the United States of America, and great part of Latin America, excluding Brazil, are part of the International Confederation, while every other magical state and nation is a member of the Roman Empire, and this includes the Goblin Conglomeration in Antarctica, a member since the Pact of Jeddah in 1796. (…) In all, the Roman Empire serves as the spiritual successor to the Atlantean Empire, which once reigned over a large part of the ancient world, reaching as far as Thailand in the East, and the entire American continent on the west.


Although while the magical empire still exists today, the Imperial Throne remains empty, which led to the creation of the Council for the Governance of the Institutions of the Empire of the Romans, known better as the Roman Regency Council, responsible for the executive, legislative and judicial branches of the Empire, having currently Romanos II, the King of Nicaea, who became a member of the council in 1864, before his ascension to the throne, as its leader. (…)The last Roman Emperor was Constantine XI Palaiologos, who died during the Fall of Constantinople, which occurred in the muggle world.


Harry's reactions as he read the topic were mixed, being shocked by the fact that the Roman Empire still existed, at least in the wizarding world, and that he had not heard of it before, especially in Hogwarts, or mentioned in any of his school books. It was rather surreal to think that it still existed, after all these years, and that Britain was in a conflict with it. Still, the books were from the 19th century, so perhaps the relations between the Empire and the Confederacy had been improved. Or perhaps not, considering the stubbornness of wizards.

Harry looked at the clock on the wall, and realized that it was already midday, and that he was getting somewhat hungry. He left the books inside his room, and went downstairs, only to find the pub somewhat empty. Tom was at the counter, seemingly waiting for someone to arrive, and he then noticed that Harry was approaching him.

"Ah, Mr. Potter, already down for lunch?" Asked the old innkeeper.

"Yeah." Replied Harry, "Are you serving lunch already Tom?"

"Quite so." Said the man, "What will you have, Mr. Potter?"

Harry glanced shortly at the menu, before deciding.

"I'll have the Pea soup." He said.

"Very well. Anything else?"

"For now no." Replied the young wizard, "I'll think about it."

Tom nodded and Harry moved to one of the tables, realizing that there was a discarded copy of the Daily Prophet on top of it. As he sat down, Harry grabbed the newspaper, and the first thing he saw was the screaming face of Sirius Black, a now common feature of the Daily Prophet. Deciding to ignore the main article, Harry moved on to other topics, focusing on the Sports section.

Soon enough, Tom came with his pea soup and warned him that it was possibly hot. Harry thanked the man and continued to read the Daily Prophet for a while. He only stopped when he felt a sharp pain on his hand, and immediately he discarded the newspaper, realizing what exactly had caused him said pain.

It was a pea.

"What the..?" He nearly shouted in surprise.

"It's the pea soup, Mr. Potter." Said Tom rather amused, "You have to eat it before it eats you."

Harry grabbed the pea which was biting him, eating it himself.

"Thanks Tom," said Harry, a bit amused as well.

He began to eat the soup and it soon became apparent that he was not going to be eaten by the peas. Eventually, more people came into the Leaky Cauldron and the pub soon became full. However, as Harry finished the soup, he noticed that a strange looking man was looking him. The man was clearly not English and was dressed in a way that resembled the Russian figures in the Encyclopædia Veneficia.

He was rather unnerved by the man and decided that it would be best if he left the pub. Harry went to the counter and gave the money to Tom, before heading out into the alley. As he walked through the near-empty alley, Harry was distracted by a poster of the Firebolt broom and stood there admiring it for a while. He was only distracted by his thoughts when he heard someone clearing his throat.

Turning around, Harry saw the same man who had been looking at him strangely inside the Leaky Cauldron.

"Are you Harry Potter?" Asked the man in a rather rough accent.

"Erm…yes…?" Said Harry, in a way that sounded more like a question.

"I am Boris Ivanovich." Spoke the man, "Forgive me for intrusion, but I would like to speak with you."

Ah, so this man was Russian. That still brought more questions to Harry's mind. Why exactly did a Russian man want to speak with him?

"What do you want with me?"

"Is important business." Said the man, "Not for public ears. There is café near the bank. We can speak there with privacy magic."

Despite being suspicious of the man, Harry still wanted to know what exactly he wanted with him. He nodded, and followed to man to the small café near Gringotts. Once the two had chosen a table, Boris cast the privacy spell.

"Now, what exactly do you want with me?" Asked the young wizard.

"As I said, I am Boris Ivanovich. I am agent of Russian government, and I am here under orders from Empress Maria."

"Empress Maria?" Asked Harry, confused.

"She is ruler of Russia and Portugal, and leader of Regency Council." Explained the man, "Powerful witch as well."

"Ok, but what does she want with me?"

"We are under orders from Empress to recover you."

Harry's eyes widened in shock.

"What!? Why!?" He nearly shouted before his tone turned into a hiss,

"What does your Empress want with me? And what do you mean with recover?"

"I do not know." Said the man, "The reasons were not given to me, only the orders."

Harry was not certain what he was feeling, but it had to be a mixture of nervousness and irritation.

"All I have been told, is that Empress wants to meet with you and she has been waiting a long time for such an opportunity." Said Boris, "I have the means here for you to meet with her, if you so wish. I assure that no harm will come to you."

The man removed a silver coin from his coat, and placed it on top of the table.

"What's this?" Asked Harry looking at the coin.

"I believe you here call it a portkey." Informed the man "It transports someone from one place to another, and this one will bring you to the Ministry of Internal Affairs in St. Petersburg, where your identity will be confirmed. After that, if you are indeed the one the Empress seeks, you shall be sent to her current location."

Harry looked at the coin with more suspicion than ever, but something inside him told him that he could trust the man. But still, part of him was still suspicious.

He crossed his arms, looking at the man with a blank expression. "Prove it," he said. "How do I know that you're not Sirius Black using a Polyjuice Potion?"

Boris turned around, looking at the interior of the café, noticing that it was mostly empty. "Come inside with me," said the apparently Russian man, getting up from his chair. "Do you know what Unbreakable Vow is?"

Harry got up from his chair as well, looking at the man with a confused expression. "Unbreakable Vow? Never heard of that."

"Is contract made between two wizards, but requires another one to seal it," explained the man. "If the terms of the vow are broken, the one who did so dies."

Harry stopped. "'re willing to do that?"

"Of course," was the simple reply.

Harry watched as Ivanovich went to speak with the man behind the counter, and after a while Boris returned with the shop's owner.

The man's eyes immediate fell onto the boy's forehead and a rather recognizable characteristic there. "Wait,'re Harry Potter!"

"Yes I am," said Harry, already used to having people know who he was. "The vow?"

"Oh, yes of course!" Said the man "Kneel and join your right hands, if you please."

The two did so, and so the shop's owner placed the tip of his wand on top of theirs.

"You have to say the terms, Mr. Potter." Stated the man. "And be careful with the wording."

Harry quickly looked at the man. "Oh, right. you, Boris Ivanovich, swear that you are not Sirius Black, or in any way a supporter of Voldemort?"

"I do," he replied as a small red flame erupted from the wand on top of their hands and began to encircle them.

"Do you swear that what you told me outside is nothing more than the truth, or at least what you believe to be true?"

"I do."

Another stream of fire came from the wand and just like the other it began to encircle the two hands.

"Are you done Mr. Potter?" Asked the shopkeeper, to which Harry nodded.

The man removed his wand, and the streams of fire began to contract until they were absorbed by their skin. Harry let go of Boris hand and looked at his own, seeing if the streams had left any marks. Apparently not.

The young wizard then got up and looked at the shopkeeper. "Thank you sir," he said.

"You're welcome Mr. Potter," replied the old man, who went back to the counter "Have a good day."

Harry left the café with Boris, and once outside he looked at the man. "Ok then," he declared. "I'll go and meet with your Empress."

Boris was certainly pleased with Harry's decision and took out the coin he had shown him before. He extended the coin to Harry, and told the young wizard to grab it. And a few moments later, neither Harry nor Boris were in England.

Author's Note:

Harry's eagerness to buy the books and their presence inside the bookshop, is a plot point that will be expanded upon later in the story.

Also, Boris's speech is intentionally broken in some parts.

The Encyclopaedia:

D. Maria III of Portugal – Born in 1924, she is the daughter of King D. Manuel II of Portugal and Empress Anastasia of Russia. As such, with their deaths, she became the Queen of Portugal in both the muggle and wizarding worlds, Empress of Russia only in the wizarding world, and with the death of her husband, the Queen Dowager and Regent of Nicaea. She is Harry's maternal grandmother, and is the widow of King Alexander of Nicaea. The Palace of Necessidades in Lisbon is her residence in Portugal. A member of the Roman Regency Council, Maria serves as its head and by consequence she is the non-imperial head of state of the Roman Empire.

D. Alexander I of Portugal and Nicaea – Born in 1920, Alexandros was the son of King Philip of Nicaea and Sophie Klementine von Habsburg. He had a profound admiration for his mother, and when he inherited the Kingdom of Nicaea from his father, he founded the Habsburg-Anemas dynasty, intent on honouring his mother's birth family. He married Maria of Braganza and had a single child with her. He became a co-ruler of Russia (only in the wizarding world) and Portugal alongside his wife, officially recognized as a regnant monarch of those two states. His reign as King of Portugal would only last a year, as he died in 1968, victim of a myocardial infarction. He served also as the head of the Regency Council before his death.

D. Maria Theresa – The sole daughter of Maria and Alexander, she was kidnapped by a group of wizard revolutionaries and brought to the United Kingdom, where she was adopted by a muggle family, and given the name of Lily Evans. She would later marry James Potter, and had a son with him, widely known as Harry. She was murdered by Voldemort, alongside her husband.

United Kingdom of Portugal, Africa and the Algarves – Proclaimed by King D. Manuel II before the Republican Revolution of 1910, the United Kingdom of Portugal, Africa and the Algarves was created with the intention of increasing Portugal's prestige after the British Ultimatum and to quell the outrage that still existed amongst the Portuguese people. The "Africa" in its name refers to the Kingdoms of Angola and Mozambique, two former colonies elevated to Kingdom status by the King as well. The United Kingdom was restored in 1967 by its President of the Council of Ministers (Prime Minister), Antonio de Oliveira Salazar, and Maria of Braganza would take the throne as Maria III.
