Chapter Text
The snow fell endlessly in Snezhnaya.
It always did. Pantalone had long stopped noticing the cold, had trained his body to ignore the bite of wind through the palace corridors, the frost that traced silver fingers across the windowpanes of his private quarters. He sat now at a desk carved from petrified wood imported from Sumeru—an extravagance, a reminder, a quiet cruelty to himself—and ran his gloved thumb along the grain.
Before him lay a ledger, its pages filled with numbers that would make nations tremble. Moratory columns and debt ratios and investment projections that he could calculate in his sleep. He had not slept in three days.
The dream was always the same. Zandik's red eyes—red, not the empty crimson of the Segments but the true vermilion of the man who had once held Pantalone's face between bloodstained hands and whispered, "You are the only variable I cannot solve for." Zandik had always spoken of love as if it were a mathematical error, a flaw in an otherwise elegant equation. Pantalone had found it impossibly endearing.
The Segments could not replicate it. They tried, of course—Omega most of all, with his precise mannerisms and carefully reconstructed memories. But they were copies, photocopies of photocopies, each generation losing fidelity until what remained was a hollow facsimile. Pantalone funded their research because Zandik would have wanted it, because the work mattered even if the workers were ghosts wearing his beloved's face. He attended their briefings, signed their requisitions, and felt nothing but the cold ache of a wound that would not close.
He closed the ledger and pressed two fingers to the bridge of his nose.
Where did you go? he asked the silence. If the Fulcrum scattered your soul, where did it land?
The snow continued to fall, and the silence gave no answer.
SIX THOUSAND KILOMETERS SOUTH
In the Grand Bazaar District, Sumeru City
The heat was suffocating, even at midnight.
Kaveh sat slumped in the corner booth of Lambad's tavern, his eighth—no, ninth—tenth?—cup of wine sweating a ring into the scarred wood before him. The tavern had emptied an hour ago. Lambad had long since abandoned his post behind the bar, leaving only a single lantern burning and a muttered instruction to "lock up when you're done, architect, and try not to drown yourself."
Kaveh had laughed at that. He was still laughing now, though the sound had grown thin and ragged, more wheeze than mirth.
Try not to drown yourself.
Too late. He had drowned four hundred years ago, in another body, in another life, and only now was the water filling his lungs.
His hands trembled as he reached for the cup. The wine sloshed over the rim, staining his fingers a deep burgundy that looked, in the flickering lantern-light, horribly like blood. Like the blood that had pooled beneath Zandik's body when the Fulcrum failed, when the coughing had finally stopped and those red, red eyes had gone glassy and still—
Kaveh slammed the cup down.
"Stop it," he hissed to himself. "Stop it, stop it, stop it—"
But the memories would not stop. They had begun two weeks ago, the night after the Palace of Alcazarzaray was completed, after Dori's final invoice had arrived with its impossibly long string of zeros, after Kaveh had realized that he would spend the rest of his life paying for a single building. He had collapsed onto the thin mattress in his rented room and closed his eyes—and woken up screaming in a language that no longer existed.
Pantalone.
The name had been the first thing to return. Then the faces: Pierro's stern countenance, Columbina's unsettling serenity, the Tsaritsa's frozen throne. Then the memories of ledgers and negotiations and the cold satisfaction of watching a rival's financial empire crumble beneath the weight of debt he had engineered. Then—and this was when Kaveh had truly begun to unravel—the memories of him.
Zandik.
The heretic scholar with the razor intellect and the quieter, hidden tenderness that he revealed only in the dark, only to Pantalone, only when his hands stopped shaking from whatever chemical he had been testing that day. Zandik, who had been expelled from the Akademiya for ideas that were not wrong but merely too early, too frightening for minds that could not conceive of progress. Zandik, who had built a machine to conquer time itself and died in the attempt, his body broken, his soul scattered across the ley lines like ashes on a winter wind.
And Pantalone—Kaveh—had watched him die. Had held his hand in that frozen laboratory, had felt the pulse slow beneath his fingers, had heard the final, rattling whisper:
"If time could be bent... I would find you again."
Kaveh pressed his forehead against the sticky table and let out a sound that was half-sob, half-laugh.
He would find him again. Zandik had promised. And what had the Fulcrum done? It had scattered Zandik's soul forward through time, and Pantalone's backward, and now Kaveh was here, in Sumeru, four centuries after his lover's death, sitting in a cheap tavern while his past self—the original Pantalone—was still alive, still breathing, still funding the damned Segments in Snezhnaya.
The cosmic absurdity of it made him giggle.
He was the reincarnation of a man who had not yet died.
He was the future of a past that was still happening.
He was, in every meaningful sense, a temporal paradox wrapped in debt and drowning in wine.
"I could ask him for money," Kaveh slurred to the empty tavern. "I could—I could just... write him a letter. Dear Pantalone, Regrator, Ninth Harbinger, my past self—I am you, but broker, and I need approximately seven hundred million Mora to pay off a palace I built for my ego. Please advise."
He burst into laughter, high and hysterical, because what else was there to do? What was the appropriate response to the discovery that your soul had been wrenched backward through the ley lines, that your previous incarnation was currently running the largest financial empire in Teyvat, that the love of your previous life had died in your arms and might—might—be alive somewhere in this very city, wearing a different face, breathing different air?
What was the appropriate response to any of it?
"There isn't one," Kaveh said aloud, philosophically, and reached for his wine again.
The cup was empty.
He stared at it as if it had personally betrayed him.
A sound at the tavern door.
Kaveh looked up, and the world tilted on its axis.
For a moment—just a moment—the lantern-light caught the figure's eyes and turned them red. Vermilion, blood-red, Zandik-red—and Kaveh's heart seized in his chest, a fist closing around the muscle, because this was it, this was the reunion, this was the moment the universe had been building toward for four hundred years—
Then the figure stepped forward into the light, and his eyes were turquoise.
Turquoise.
Not red. Not Zandik. Just...
"Alhaitham," Kaveh breathed, and the name came out cracked down the middle.
The Scribe of the Akademiya stood in the doorway of Lambad's tavern at midnight, his silver hair tousled by the humid Sumeru wind, his arms crossed over his chest, his expression radiating the particular brand of long-suffering exasperation that Kaveh seemed to inspire in him by existing. He was dressed down—no cape, no earpieces, just a simple dark tunic—which meant he had come from home, not from the Akademiya.
He had come looking for Kaveh.
That realization landed somewhere in Kaveh's wine-sodden brain like a stone dropped into still water, sending ripples through the chaos of his thoughts.
"You missed three client meetings today," Alhaitham said, his voice flat and unhurried. "Dori has been attempting to contact you regarding her repayment schedule. The Dendro Archon herself sent a missive requesting a consultation on the new library wing, and you were nowhere to be found. I have now located you."
He paused, surveying the disaster that was Kaveh: the wine cups, the ink-stained fingers, the tear tracks cutting through the dust on his cheeks, the wild, haunted look in his carmine eyes.
"You are drunk," Alhaitham concluded.
"Astute," Kaveh slurred, and a small, bitter laugh escaped him. "The Akademiya's finest mind, ladies and gentlemen. He can identify... intoxication. Give him a medal."
Alhaitham's jaw tightened almost imperceptibly. He walked across the tavern floor with the measured steps of a man who had never stumbled in his life, stopped at Kaveh's booth, and looked down at him.
"You cannot stay here."
"Watch me."
"Kaveh."
"What?"
The silence stretched. Alhaitham's turquoise eyes—not red, not red, why could they not be red—studied Kaveh's face with an intensity that made the architect want to crawl out of his own skin. He was being catalogued, he realized. Analyzed. Every detail of his dishevelment was being noted and filed away in that infuriatingly orderly mind.
"Your landlady evicted you," Alhaitham said. It was not a question.
"How did you—"
"You are living out of a single bag, which is currently stored beneath this table. Your hands are stained with ink and cheap wine, which suggests you have been writing and drinking simultaneously—the letters to Dori, I presume, attempting to negotiate an extension. You have been here for at least four hours, based on the number of cups and the rate at which Lambad pours. And you have been crying."
The clinical recitation of his misery should have been infuriating. Instead, Kaveh felt something crack open inside his chest—a fissure through which exhaustion and despair and the impossible weight of four hundred years of memory came flooding.
"I am fine," he said, and the lie was so transparent that even he could hear it.
"No," Alhaitham said quietly. "You are not."
The words hung in the air between them, and in the silence, a strange thing happened.
Alhaitham—cold, rational, emotionally constipated Alhaitham—sat down on the bench opposite Kaveh. Not gracefully. Not smoothly. He simply sat, as if the decision had bypassed his brain entirely and gone straight to his legs, and now his legs were committed to the course of action and the brain would simply have to catch up.
"I dislike seeing you like this," Alhaitham said, each word seeming to cost him something. "It is... inefficient."
For reasons Kaveh could not articulate, this made the laughter bubble up again. "Inefficient? My life is falling apart, I'm hundreds of millions of Mora in debt, I'm... I'm..." I'm remembering a past life. I'm watching my own history walk around in Snezhnaya. I loved a man with red eyes who died in my arms and I see his ghost in your face. "...and you're concerned about efficiency?"
Alhaitham's expression flickered—the briefest twitch at the corner of his mouth. "I am concerned about you. I am simply... poor at expressing it."
Kaveh stared at him.
Alhaitham stared back.
"This is the strangest conversation we have ever had," Kaveh said.
"You are not usually this drunk."
"And you are not usually this... this..."
"Decent?"
"I was going to say 'present.'"
Alhaitham made a soft sound—not quite a laugh, but the suggestion of one, a ghost of amusement that Kaveh had learned over the years to recognize. It was, impossibly, one of his favorite sounds in the world.
Was that a Kaveh thought? Or a Pantalone thought?
The lines were blurring. They had been blurring for days.
"Come home with me," Alhaitham said.
Kaveh's heart stopped.
The words were simple—practical, even. A rational solution to the problem of Kaveh's homelessness. Alhaitham had a house. Kaveh did not. Ergo, Kaveh should go to Alhaitham's house. It was the sort of logic that Alhaitham applied to everything, stripped of sentiment, clean as a mathematical proof.
But Kaveh's chest was full of Pantalone, and Pantalone had once heard similar words in a laboratory north of Snezhnaya, spoken by a man with red eyes and a ruined body, and the echo of it now nearly shattered him.
Stay with me tonight. Please. I do not wish to be alone.
"I can't," Kaveh whispered.
"Why not?"
Because you look like him. Because you don't look like him. Because your eyes are the wrong color and your hands are the wrong shape but the way you tilt your head when you're puzzled is exactly, precisely, terrifyingly the same—
"I would be a terrible housemate," Kaveh said. "I don't sleep regular hours. I leave blueprints everywhere. I talk to myself. I'm drowning in debt. I'm..." I'm haunted. "I'm a disaster."
"I am aware," Alhaitham said. "I have known you for years. The disaster is not new information."
Despite everything, Kaveh smiled. It was a small, fragile thing, but it was real—the first real smile he had managed in days.
"Come home," Alhaitham said again. "I have a spare room. You may stay as long as you need. I will not even charge you rent."
"Generous," Kaveh murmured. "What's the catch?"
"The catch is that I will continue to critique your architectural choices."
"My architectural choices are revolutionary."
"Your architectural choices prioritize aesthetics over structural integrity."
"Beauty is a form of structural integrity—"
Their bickering was automatic, a well-worn path their minds had traced a thousand times before. It was familiar. It was comforting. It was, Kaveh realized with a jolt of something that felt dangerously like hope, exactly what he needed.
Alhaitham extended a hand across the table. His fingers were long and steady, the hand of a scholar who had never done manual labor. Zandik's hands had been scarred, the knuckles perpetually bruised from experiments gone wrong, the nails stained with chemicals that never quite washed out.
Different hands, Kaveh thought. Different hands. Different eyes. Different man.
But the gesture—the silent offering of help without expectation, without condition—that was the same.
That was so achingly, devastatingly the same.
Kaveh took his hand, and Alhaitham pulled him to his feet.
The world spun. Kaveh staggered, and Alhaitham caught him—one arm around his waist, steady and strong, holding him upright. They were close now, close enough that Kaveh could see the individual strands of silver in Alhaitham's hair, could smell the faint scent of ink and parchment and Sumeru roses that always clung to him. Close enough that their breath mingled in the narrow space between their lips.
"The room," Alhaitham said, his voice slightly rougher than before, "is upstairs. At my house. Which is a walk from here."
"Right," Kaveh said.
"Can you walk?"
"Maybe."
"Then I will assist you."
Alhaitham did not release him. His arm remained around Kaveh's waist, their bodies pressed together from shoulder to hip, as he guided the architect toward the tavern door. Kaveh leaned into the warmth, too exhausted to fight it, too drunk to pretend he did not want it.
The touch was grounding. It was the first thing that had felt real since the memories began.
They stepped out into the Sumeru night. The air was thick with humidity and the scent of padisarahs, and the moon hung low and golden over the Akademiya's spires. Kaveh looked up at it and felt, for just a moment, the staggering loneliness of being a soul displaced in time. He was Pantalone. He was Kaveh. He was both and neither, a palimpsest of two lives written over each other, the old text bleeding through the new.
"Alhaitham," he murmured.
"Mm."
"Do you ever feel... like you've lived before? Like there's someone else inside your skin?"
Alhaitham was silent for a moment. "No," he said finally. "I am myself. Nothing more, nothing less."
Kaveh closed his eyes. "That must be nice."
"It is practical."
They walked on. The streets of Sumeru City were empty at this hour, the market stalls shuttered, the scholars tucked into their dormitories. Only the streetlamps witnessed their slow progress—two men, one supporting the other, moving through the dark.
And Kaveh, despite the wine and the exhaustion and the gravitational pull of despair, found himself cataloguing the man beside him the same way Alhaitham had catalogued him.
The precision of Alhaitham's stride, adjusted now to accommodate Kaveh's stumbling. The way his hand rested against Kaveh's waist with a gentleness that belied his clinical demeanor—not gripping, not controlling, just... present. The slight furrow between his brows, which Kaveh had learned long ago meant that Alhaitham was thinking about something he could not resolve.
Zandik had worn that same furrow.
The realization hit Kaveh like a physical blow. He stumbled, and Alhaitham tightened his grip.
"Careful."
"The third step," Kaveh mumbled.
"What?"
"There's a loose stone on the third step of the—the Akademiya's north entrance. I tripped on it three times before I learned to step around it."
Alhaitham looked at him strangely. "That stone was replaced last month. The repairs were completed while you were finishing the Palace."
"Oh." Kaveh's heart was beating too fast. The third step was a memory from Pantalone's life—the Akademiya had looked different four hundred years ago, but the north entrance had the same flaw in the stonework, the same loose flagstone that Zandik had always complained about in his letters. They cannot even maintain their own walkways, Pantalone. How can they presume to judge my research?
"I must be drunker than I thought," Kaveh whispered.
"Evidently."
But Alhaitham was still looking at him with that expression—the furrowed brow, the searching gaze—and Kaveh felt exposed, flayed open, as if Alhaitham could see right through his skin to the second soul lurking beneath.
Alhaitham's house was exactly as Kaveh remembered it from his last visit, years ago, when they had still been students collaborating on a project that was doomed from the start. The front room was lined with bookshelves, meticulously organized by subject and then by author and then by some arcane system that only Alhaitham understood. A single desk dominated the center of the space, covered in neat stacks of paper. There were no personal effects, no decorations, no sign that a human being lived here at all—except for the single potted sumeru rose on the windowsill, which Kaveh knew for a fact Alhaitham had been tending for six years.
"This way," Alhaitham said, guiding him toward a door at the back of the room. "The spare room has a bed and a desk. The washroom is across the hall. I will bring you water and something to eat."
"You cook?"
"I keep provisions. I did not say I cook."
"Of course not. That would be too human for you."
Alhaitham paused at the door. Without turning around, he said: "I am human, Kaveh. I simply do not advertise it."
He pushed the door open. The spare room was small and spare, like everything else in Alhaitham's life, but the bed was made with clean sheets and the window looked out onto a quiet courtyard filled with moonlight.
"The bathroom," Alhaitham said, "is—"
"Across the hall. Yes. You said." Kaveh pulled away from Alhaitham's supporting arm and swayed on his feet. "I can manage from here."
"You cannot."
"I've been managing my whole life."
"That is not the same as managing well."
The retort was so quintessentially Alhaitham that Kaveh laughed—a real laugh this time, surprised out of him like breath from a struck diaphragm. And that was when the world tilted again, not from the wine this time but from the sheer overwhelming reality of being here, in this house, with this man, whose turquoise eyes held the same sharp intelligence as the red eyes that had once looked at Kaveh (Pantalone, Pantalone) across a candlelit laboratory and said I think I love you, and I do not know what to do with that.
The memory hit him like a wave, and Kaveh reached out blindly, grabbing the doorframe for support.
"Easy," Alhaitham said, and he was there immediately, hands on Kaveh's shoulders, steadying him. "You need to lie down."
"I need—" Kaveh started, and then the words tangled in his throat, and what came out instead was: "Zandik."
Silence.
Alhaitham's hands stilled on Kaveh's shoulders.
"What did you call me?"
And Kaveh, drunk and reeling and drowning in two lives, heard the question through a fog of wine and grief. He realized what he had said. What name he had spoken. The one name that had no business on his lips in this century, in this city, with this man.
Oh, gods.
"Nothing," Kaveh said quickly. "I didn't—"
"You said something."
"I said... I said you're a dick." Kaveh forced a laugh, high and brittle. "For—for helping me. I called you a dick for helping me. Because you're so—you're so infuriatingly decent when no one's watching, and I hate it, and—"
Alhaitham stared at him for a long moment. His expression was unreadable, his turquoise eyes glinting in the candlelight like polished stones.
"It sounded like a name," he said.
"It wasn't."
"Kaveh."
"Alhaitham."
The standoff stretched. Kaveh's heart pounded against his ribs, rabbit-fast, rabbit-frightened. If Alhaitham pressed—if he asked again—Kaveh did not know what he would do. He could not explain. He could not say Zandik was a heretic scholar who died four hundred years ago and I loved him and you walk like him and talk like him and the shape of your intelligence is exactly the same, and I am losing my mind trying to figure out if you are him, or a Segment of him, or a child of his bloodline, or just a cruel cosmic coincidence—
Alhaitham exhaled slowly, and his hands dropped from Kaveh's shoulders.
"Go to bed, architect."
"Alhaitham—"
"We will discuss this in the morning. When you are sober."
Kaveh opened his mouth to argue, to deflect, to do something other than stand there shaking under the weight of four hundred years of secrets. But Alhaitham was already turning away, already walking back toward the front room, his silhouette sharp and precise against the candlelight.
At the threshold, he paused.
"You are not a burden, Kaveh," he said, without looking back. "Whatever debt you carry—whatever weight—you do not have to carry it alone."
He disappeared into the darkness.
Kaveh stood in the doorway of his new room, gripping the frame so hard his knuckles went white, and felt his heart crack along a fault line that had been forming for four centuries.
You do not have to carry it alone.
Zandik had never said that. Zandik had carried his burdens in silence, had hidden his pain behind equations and experiments, had refused to let Pantalone share the weight of his slow, inexorable decline. This is my failing, Zandik had said in those final weeks, when his hands trembled too badly to hold a pen. My miscalculation. I will solve it myself.
But Alhaitham—Alhaitham, who had been his rival, his opponent, the bane of his existence since their Akademiya days—had offered to share the load without even knowing what it was.
Kaveh closed the door and slid down it, his back against the wood, his knees drawn up to his chest.
He did not cry. He had no tears left. But he sat there for a long time, staring at the moonlight on the floorboards, listening to the distant sounds of Alhaitham moving about in the front room.
I see him in you, Kaveh thought. I see Zandik in every word you speak, every gesture you make, every carefully guarded emotion you refuse to name. And I cannot tell if I am hallucinating, or if the universe has a crueler sense of humor than I ever imagined.
Who are you, Alhaitham?
Who are you, really?
The question would haunt him for months to come. And the answer, when it arrived, would burn the world down around them both.
Three thousand kilometers north, in a palace of ice and shadow, Pantalone opened his eyes.
He had been dreaming—not of Zandik's death this time, but of something stranger. A tavern in Sumeru, warm and golden with lantern-light. A man with carmine eyes and wheat-gold hair, weeping into his wine. A voice that had felt, impossibly, like his own.
I could ask him for money, the voice had said. My past self... I am you, but broker.
Pantalone rose from his desk and crossed to the window. The snow was still falling, blanketing the world in white silence.
He pressed one gloved hand against the glass and stared out into the frozen dark.
Something is coming, he thought. Something that has waited four hundred years to arrive.
And somewhere, in the ley lines that hummed beneath Teyvat like the strings of a lyre, the Fulcrum's final echo began to stir.
