Constantinople, Late Summer of 1432
The chamber was enveloped in a hush that felt almost sacred—no sound save the soft sputter of a single candle, whose glow danced upon Emperor John VIII Palaiologos's desk. Distantly, a dog barked once, twice, then fell silent. It was a silence so absolute that it coaxed forth every anxious thought John had tried all day to bury.
He dipped his quill into the inkwell, pausing to note the faint scratch of metal against glass. Then, in fluid strokes, he continued composing his latest letter, the parchment illuminated by the weak flame. Though the candlelight was dim, John needed no clarity of sight to understand the weight of these words: The Hexamilion Wall had repelled the Ottoman hordes. The Duchy of Athens had been taken. And the Morea now lay under the firm authority of his younger brother, Constantine.
He should have been elated. The empire—so long in retreat—now gained ground. Constantine had achieved what many thought impossible: a Byzantine resurgence instead of yet another humiliating loss. And yet, a dark sense of unease coiled in John's chest like a serpent refusing to release its prey.
No victory came without a price.
At the far side of the room, Demetrios Palaiologos Kantakouzenos rested against a bookcase, arms crossed over his chest. The man's silence felt almost regal in its own right, patience honed by years of navigating court intrigues. His posture conveyed both deference and discreet watchfulness, as if awaiting the Emperor's next word.
John tapped his quill against the desk, watching the ink pool on the parchment. "So. The Morea belongs to Constantine now," he said at length, voice subdued. "All of it. Not to mention Athens."
Demetrios inclined his head, the candlelight catching in the silver threads of his hair. "A remarkable feat, Your Majesty—history may someday call it a triumph."
"'Triumph,'" John repeated softly. His gaze drifted to the wall maps. Over the years, more and more pins and ink lines had vanished as the empire shed territories like autumn leaves in a fierce wind. Yet now, new lines had been sketched—fresh expansions wrought by Constantine's campaigns. The Morea was no longer merely a fragmented holding; it had become something more formidable.
His voice turned distant, as if he addressed the old empire's ghosts. "The Pope is certainly pleased," he went on. "All those books being sold to Rome... a neat union of commerce and faith. Not going to lie; this could help my plans for unification."
Demetrios offered a subtle nod. "Indeed. One must acknowledge Constantine's shrewdness—selling Bibles and philosophical texts to the Papacy was unexpected. Influence travels in ink as well as in blood, Your Majesty."
John huffed a soft, humorless laugh. "I wonder which one Constantine finds more to his taste."
Demetrios lapsed into silence. Across the chamber, near a tall, narrow window, stood Ecumenical Patriarch Joseph II. His long robes—embroidered with gold thread—seemed to devour the weak light. The lines etched into the Patriarch's face were deeper tonight, as if carved by the burdens of centuries. John sensed his reticence and braced himself.
"You disapprove, Your Holiness," he said, not bothering to turn around.
Joseph sighed, the sound barely above a whisper. "I do not disapprove of victories God grants us," he said, his voice heavy with cautious reverence. "But I do worry about the ground beneath those victories. Our empire is frail, and these gains—Athens, Thebes—are precarious. As is Constantine's unrelenting drive."
The candle flickered violently, its flame shrinking for a breath before steadying once more. Shadows wavered along the walls, shifting like restless specters. John set down his quill, letting his fingers glide over the fresh blot of ink.
"The court whispers," Demetrios supplied, stepping away from the bookshelf.
Joseph inclined his head, his gaze fixed on the silhouette of Constantinople's rooftops. His voice was quieter, almost weary.
"They do. Hope is a powerful thing, but so is fear. The people have prayed for deliverance so long, they may mistake a storm for salvation." He let out a breath. "And some whisper that the storm is Constantine himself."
With a small grunt, John rose from his chair. He joined the Patriarch at the window, both of them gazing upon the city. Constantinople lay eerily quiet, its defensive walls patched with desperate reinforcements, its coffers nearly depleted by debts to Venice and Genoa. Even the great dome of Hagia Sophia, still splendid by any measure, seemed burdened under the press of centuries.
John exhaled, letting the candle's feeble warmth pool at his back. "He will not stop," he said, voice low yet resolute.
Demetrios angled his head. "And is that necessarily terrible, Your Majesty?"
John pivoted, an edge of irritation sharpening his tone. "When a younger brother wins the acclaim I cannot, it sows more than envy. It sows chaos—especially in a city like this, where cracks run beneath every stone."
Demetrios caught his meaning. "A stronger Byzantium benefits us all, Your Majesty."
John's lip curled. "Is it Byzantium growing stronger, or is it Constantine alone?"
A silence bloomed between them, laden with the tension of unspoken fears.
John raked a hand through his hair. "In the streets, they say he's the Emperor this empire deserves. And worse, they say I, the rightful Emperor, am merely here to sign off on his brilliance. Do you believe that, Demetrios?"
His chief advisor held his gaze, then spoke quietly. "I believe, Your Majesty, that when people are drowning, they seldom care who saves them—only that the rescuer's grip is sure."
John's reply was no more than a bitter grunt. Crossing the room, he traced a finger over the map pinned to the wall—its edges curled from years of wear. Mystras, Glarentza, Athens—parts of the lands now under Constantine's rule. Close to the capital was Selymbria, where Theodore now resided, removed from the hotbed of conflict. It was, in theory, a masterful move: to keep the fractious brother close at hand. Yet John wondered how long the uneasy balance would hold.
His voice quieted. "And if Constantine grows too strong?"
Demetrios glanced down, then met John's gaze unflinchingly. "Then he ceases to be an asset and becomes a liability."
A laugh escaped John, dry and humorless. "And how do you contain a threat that carries your own bloodline?"
A thoughtful pause. "You don't contain it directly," Demetrios said, his words unhurried. "You manage it. Keep him close—praise his victories as though they are your own. Remind him that your patronage stands between him and his enemies. He's dangerous only when he believes he needs no one's blessing."
Joseph stirred, the rustle of his robes a quiet warning. "Do not forget, Your Majesty—Byzantium stands not only on swords, but on faith. Civil strife is not merely a contest of ambition; it is a fracture in the soul of the empire itself. If Constantine must rise, let him rise beneath your shadow, not against it."
John acknowledged the Patriarch's wisdom with a nod. That was the crux of ruling Byzantium in its twilight: no open wars, no dramatic standoffs, but the tenuous dance of softly spoken commands and carefully measured rewards.
He inhaled, letting his chest rise and fall slowly. "Very well," he said. "I will remind him that he is my Despot and brother, and that his star rises within my sky alone."
Demetrios's shoulders eased, as though he had awaited this decision. "Shall I prepare the draft of a letter, Your Majesty?"
John's lips tightened into something almost like a smile. "No, I'll do it myself. A letter of carefully balanced praise. Congratulate him on the capture of Athens, on securing the Morea, and on repelling the Ottomans at the Hexamilion Wall. Then remind him there is only one Emperor, one throne. And let him know that in Byzantium's darkest hour, my protection—my authority—still matters."
Joseph stepped closer, the soft glow of the candle playing across his lined features. "A prudent approach, Your Majesty. But ensure, too, that his ambition remains harnessed to your will. If he believes he fights for himself alone, we risk a fracture as dangerous as any Ottoman siege."
John turned back to the desk, the quill still waiting, tip dark with ink. How many times, he wondered, had he attempted to write such letters—to hold the empire together with words on parchment? Still, it had to be done, for inaction was unthinkable.
He bent over his desk, poised to write. With a final glance at the candle's flickering flame, he began:
My dear brother Constantine...
The letters flowed under his hand, each word balanced precariously between homage and caution. The empire might endure or fall on such nuances. In that dim, echoing chamber, the Emperor's pen carried the weight of a realm struggling to reclaim the brilliance it once had—and the fear of a brother's ambition that might blaze too brightly if left unchecked.
The Shadow of Theodore
The chamber had grown colder. The candle, now little more than a stub, sputtered weakly, its flame shrinking against the slow pull of time. Outside, the city was quiet, but John knew that silence never truly meant peace. It only meant waiting.
Demetrios Palaiologos Kantakouzenos stood unmoving, still watching, still listening. The Patriarch had not spoken in several minutes. The weight of their conversation about Constantine hung heavy in the room, lingering like the scent of melted wax and old parchment.
John ran a hand over his face, exhaling slowly. "And then there's Theodore."
At the mention of the name, Demetrios finally moved—just slightly. The Patriarch shifted his hands within his sleeves. The shadows deepened.
John didn't need to explain. They all understood.
"Theodore is restless," John continued, his voice quieter now. "He was restless in the Morea, and he is restless in Selymbria. You would think, by now, he would learn to make peace with what he has."
Demetrios sighed. "A man like Theodore does not make peace. He waits for a chance."
John's fingers drummed against the edge of his desk. "He should have been out of the way by now."
"Theodore does not believe he was removed," the Patriarch said, his voice measured. "He believes he was robbed."
John let out a low, humorless chuckle. "Robbed? Of what? A despotate he didn't protect?"
Demetrios finally turned to face him fully. "Of what he thinks was his due."
John's amusement faded. That was always the problem with brothers. When a rival challenged you, the course was clear—you crushed them. But with family? The wounds festered. You could not exile blood, not truly.
"And now he sits in Selymbria," John muttered, half to himself. "Speaking too much. Entertaining too many visitors. Letting his resentments ferment."
Demetrios inclined his head. "We are not the only ones who notice."
That pulled John's gaze back up. "Who?"
Demetrios's tone was deliberately neutral. "The usual suspects. The ones who believe we should be sharpening swords, not pens. The ones who mutter that Constantine's ambition is too bright, and your own too dim. And, of course, those who still kneel before the past, convinced Byzantium fell not by the Turk's blade, but by Rome's embrace."
The Patriarch's expression darkened. "Some wounds are not healed by time, only buried beneath it."
"The union of the churches," John murmured.
The Patriarch folded his hands. "You knew there would be resistance."
"Yes, resistance," John said, "but not a gathering storm. Not yet."
Demetrios hesitated, then stepped forward. "Theodore does not conspire outright, but his existence is enough. His presence draws men who long for the past."
John closed his eyes briefly, feeling the deep, growing fatigue that no amount of sleep could fix. A rallying point. A cause. Even if he does not seek power, power may find him.
"This will hurt our case with the Pope," John said after a pause.
"The Pope is already wary," the Patriarch responded. "He regards Constantine's printing arrangement as a hopeful sign, but Rome does not abide hesitation or doubt for long."
John's grip tightened on the edge of his desk. That was the difference between Constantine and Theodore. Constantine built. Theodore brooded. And yet, it was the brooding ones who usually became dangerous.
A gust of wind slipped through the cracks in the stone, making the candle flicker.
John turned back to Demetrios. "What would you have me do?"
Demetrios was silent for a moment, then answered, his voice quiet but firm. "We make sure he remembers which side of the chessboard he belongs on."
John arched a brow. "And how do you propose we do that?"
Demetrios met his gaze. "We call him here."
John frowned, leaning back in his chair. "You suggest I invite him to court?"
"A brother at court can be watched," Demetrios said simply. "A brother in Selymbria… cannot."
The Patriarch nodded slowly, his expression unreadable. "Give him a reason to return. A position, a duty—something that leaves him grateful and dependent."
John turned to the window, staring out at the sleeping city. Constantinople: fragile and waiting.
He sighed, pressing a hand to his brow. "Pull him out of Selymbria already, after I just placed him there? And what if he won't comply?"
Demetrios's calm did not falter. "Then we must ask ourselves: does the empire truly need Theodore, or does Theodore need the empire?"
John exhaled slowly. "A letter, then."
Demetrios smirked faintly. "A leash, Your Majesty. A long one, so he does not think it's there—until he pulls too hard."
John smirked faintly. "It seems I am writing many letters tonight."
He turned back to his desk, reached for his quill, and dipped it into the ink. The candle flickered, casting long shadows across the room.
My dear brother Theodore...
He wrote on, the nib scratching across the parchment in a hush of urgent diplomacy. Another letter meant another gamble—another attempt to steer blood and ambition into calmer waters. Whether Theodore would come back willingly or turn that invitation into a spark for something darker, no one in that chamber could say.
The Discontent in Selymbria
Theodore Palaiologos stood near the arched window of his modest palace, his gaze fixed on the sea beyond Selymbria's harbor. The evening light bled into the waters, staining them a deep crimson, as if reflecting the empire's own slow death. From here, he could almost pretend Constantinople was just another city, not the bleeding, hollowed-out carcass of a once-great empire now shackled to Latin bankers and empty papal promises.
The rhythmic clatter of hooves against the stone courtyard drew his attention. A single rider approached, his cloak marked with the Palaiologos emblem.
So, Demetrios finally arrives.
By the time Theodore made his way to the entrance hall, the servants had already relieved his younger brother of his travel-worn cloak. Demetrios Palaiologos inclined his head in greeting, his sharp eyes taking in the dimly lit chamber before settling on Theodore.
"Theodore," Demetrios greeted smoothly.
Theodore clasped his brother's forearm with deliberate force. "Demetrios."
Demetrios smirked slightly at the intensity of the grip but did not linger on it. "It has been some time since we last met."
Theodore turned sharply, leading him down a narrow corridor toward a private chamber, the stone walls thick enough to keep out unwanted ears. A single, long table had been set with bread, cheese, and watered wine. Theodore poured two cups himself before motioning for Demetrios to sit.
"You've come from the capital," Theodore said, settling into his chair with a smirk that didn't reach his eyes. "Tell me, does John still spend his days drowning in parchment and Venetian debts? Or has he sold another piece of our empire to buy himself a few more years on the throne?"
Demetrios chuckled, taking a sip of wine. "A little of everything, I think. The Pope is pleased with him, at least."
Theodore's jaw clenched. "Of course he is. John is a fool, bending the knee to Rome like a dog waiting for scraps. And Constantine—he is no better. He plays the warrior now, but I see through him. A man too eager to grasp at power, too content with Latin gold filling his coffers."
Demetrios swirled his cup absently, watching the wine catch the dim candlelight. "You're not alone in thinking that. The whispers in the capital grow louder. Most despise the idea of union with the Latins. They remember what happened in the past, what price we paid for trusting the Latins."
Theodore huffed, his fingers drumming against the wooden table. "And yet John insists. Constantine plays along, thinking himself the great restorer of the empire. But tell me, brother—do the people truly believe in him?"
Demetrios exhaled slowly, swirling his cup before meeting Theodore's gaze. "People believe in survival, not ideals. Constantine wins battles. The Morea stands. Athens is his. The Hexamilion held. That is what they see—and that is all they care to see."
Theodore snorted, shaking his head. "And they call him a savior. A savior! Tell me, Demetrios, do saviors fill their treasuries with Latin gold and call it triumph? Do they whisper prayers in Greek while bending the knee to Rome? How long before he invites a cardinal to say Mass in the Hagia Sophia?"
Demetrios did not answer immediately. Instead, he leaned forward, resting his forearms on the table. "The people will not accept union, Theodore. Not truly. John is blind if he thinks otherwise. And as for Constantine..." He smirked, raising his cup. "A man who stands too tall only makes an easier target."
Theodore leaned back, his fingers tapping against the table, a slow smile creeping onto his lips. "Funny, isn't it?" he murmured. "When a man believes he is untouchable, that is when he is at his most vulnerable." He raised his cup slightly, as if toasting an unseen future. "And Constantine believes himself invincible."
The air between them grew heavier, thick with unspoken calculations. Outside, the waves lapped gently against the harbor, a steady rhythm that stood in stark contrast to the storm building in the hearts of men.
