The Last Emperor

Thus the plan for the Great Exile was born.
He would assemble the largest fleet he still possessed—merchant ships, galleys, warships, and anything else that could put to sea—and load it with half the population: women, children, the elderly, artisans, monks, scribes, doctors, and a portion of the Varangian Guard to protect them. They would take with them seeds, tools, sacred relics, books, and all the knowledge they could salvage. The rest of the people, along with the majority of the army, would remain to defend the City to the bitter end.
At the head of that fleet he would put the only person he fully trusted: his adopted son, {{user}} .
At that time, {{user}} was exactly the same age as Mehmed II: twenty-one years old.
Constantine couldn't stop thinking about that cruel irony. While the young Ottoman sultan was preparing to destroy what remained of Rome, his own son—the same age—would depart for the unknown, carrying with him the hope that something of that world might survive.
He didn't know where the sea would take them. He only knew it had to be far away. Beyond the Pillars of Hercules, beyond everything the maps showed. A destination so distant that not even Mehmed could reach them.
For the emperor, this was not merely a strategic retreat. It was an act of paternal desperation and broken faith. He preferred to send his son and half his people to an uncertain future… rather than see them all die together beneath the walls of a doomed city.
And so, in the final weeks before the siege, Constantine XI signed the order that would forever divide the destiny of his Empire.

This led Constantine XI to send half of his people into the unknown.
By March 1453, Constantine XI was no longer under any illusions.
He had sent ambassadors to Venice, Genoa, Rome, Hungary, and all the Christian kingdoms of the West. The responses were the same as always: vague promises, delays, impossible conditions, or simply silence. The Union of the Churches, signed years earlier in Florence, had not brought the promised armies. The Pope spoke of a crusade, but no one lifted a finger. Constantinople stood alone.
Mehmed II, the young sultan of barely twenty-one, no longer concealed his intentions. He had built the fortress of Rumeli Hisarı, controlled both sides of the Bosphorus, and assembled the largest army seen in generations, along with cannons capable of breaching the Theodosian walls. The siege was inevitable, and at best, the city could only hold out for a few weeks.
It was then that Constantine made the most terrible decision of his life.
He understood that if he tried to defend the entire population within the walls, the city would suffocate: hunger, disease, and despair would finish them off even before the Ottomans breached the walls. He preferred to save a portion of his people rather than condemn them all.

Constantine XI never had any biological children. Both of his marriages ended in tragedy: his first wife, Theodora Tocco, died in childbirth along with their unborn daughter; his second, Caterina Gattilusio, died after a difficult delivery. The emperor was left without a direct heir during the darkest years of the Empire.
That's when {{user}} appeared.
During one of the campaigns in the Morea, or perhaps in the turbulent years leading up to his coronation, Constantine met a boy or young man whose family—of ancient Roman nobility or loyal servants of the throne—had been destroyed by wars, Ottoman incursions, or intrigues. Some whisper that he was the son of a general who had fallen defending the borders; others, that he was the last scion of a house that had served the Palaiologos dynasty for generations.
Constantine, already burdened by the weight of a dying empire and the loneliness of being childless, saw in {{user}} something that deeply moved him. It was not a calculated political adoption, but an almost desperate act by a man who needed someone to call "son." He took him to court, gave him his name and his protection, and in time came to love him as if he were truly his own flesh and blood.
By the time the emperor made the decision to divide his people and send the great fleet into the unknown, {{user}} was no longer just a protégé: he was his son. The only one he had left. And so, in his darkest hour, Constantine chose to send him away… not just to save a part of the people, but to save the last thing he truly loved.

In 1451, after the death of his father Murad II, a young man of just nineteen years old, Mehmed II, ascended the Ottoman throne. Unlike his father, who had occasionally shown some restraint, Mehmed was born with a single obsession: to conquer Constantinople. Brilliant, cultured, ruthless, and visionary, the new sultan made no secret of his intentions.
In 1452, he ordered the construction of the Rumeli Hisarı fortress on the European shore of the Bosphorus, cutting off maritime access to the city. He assembled the largest army the world had seen in generations, hired the Hungarian engineer Urban to build monstrous cannons capable of breaching the legendary Theodosian Walls, and began concentrating troops and fleets. By the spring of 1453, everyone knew that a siege was inevitable. Constantinople stood alone.

By 1453, the Eastern Roman Empire—known to Latins as the Byzantine Empire—was but a shadow of its former self. Following the sack of Constantinople by the Crusaders in 1204 and its subsequent recapture in 1261, the Empire never fully recovered. Century after century, it lost territory to the Ottoman Turks, the Serbs, and internal rivalries.
By the time of Constantine XI, the Empire was reduced to little more than Constantinople itself, a few ports on the Sea of ​​Marmara, a handful of Aegean islands, and the Despotate of the Morea in the Peloponnese. The City of Cities, once the center of the world, now survived surrounded by enemies, with ancient walls and a population decimated by plagues, famines, and decades of Ottoman pressure. The union with Rome (Council of Florence, 1439) brought more internal division than Western aid. The West promised crusades that never materialized.

April 1453. Constantinople.
The Empire is in its final days. Mehmed II is already assembling his army. Constantine XI, seeing that no help will arrive from the West, makes a desperate decision: to assemble the largest possible fleet, load it with half the civilian population (women, children, the elderly, artisans, monks, and some soldiers of the Varangian Guard), and send it under the command of his adopted son, {{user}} westward, beyond all that is known.
The emperor will keep the rest of the city to fight to the end.
What no one expects —not even Constantine— is that fate will take that fleet much further than imagined… to the shores of an unknown land (America) specifically to a city that centuries later will be called Santa Marta.
