Chapter Text
Golden walls. Heat pressing against skin like a living thing, the air thick with the smell of baked clay and river water and something older — cedar resin, burnt offerings, the mineral tang of divinity spending itself against the world. Uruk. The name arrived not as word but as weight, a city's gravity pulling at him from across five thousand years.
He was walking through the gardens. He knew this because the light was green-gold, filtered through canopy, and the irrigation channels murmured beneath the pathway — sounds so familiar they had no names, only the shape of things that had always been there. His hands were at his sides. His body felt wrong; too heavy, too present, too here in a way that suggested he was remembering being here rather than being here, and the distinction mattered in a way his dreaming mind could not articulate.
Someone was ahead of him on the path.
Green hair catching the filtered light. Bare feet on the stone — no, clay; the paths in the garden were clay, baked and smooth. The figure moved with the particular grace of something not entirely human and not entirely not, a body that existed at the boundary between categories the way a river exists at the boundary between land and sky.
He tried to speak. The name was there — had always been there, had never left — but the air in his lungs was wrong. Thicker. The garden light was dimming, and the green-gold was becoming something else, a color that had no name in any language he spoke because it was the color of things ending. The figure ahead of him turned, and for one instant the face was clear: calm, sad, unsurprised by what was coming. The mouth moved. Words he could not hear over the sound of —
Mud.
It came from below and above simultaneously, black and viscous and carrying the weight of every grievance the world had ever swallowed and failed to digest. It tasted of bile and iron and something more fundamental — the raw substrate of suffering, unprocessed, indiscriminate, the hatred of a species turned inward and made liquid. It flooded the gardens. The irrigation channels reversed. The green-gold light drowned.
The figure ahead of him dissolved. Not violently — gently, the way a reflection dissolves when you touch the water. One moment present, one moment gone, and the mud where they had stood carried no trace.
He was drowning. He was being born. The distinction was academic.
Gilgamesh opened his eyes to Fuyuki.
The wind was the first thing — sharp, maritime, carrying the salt-rot of the harbor three kilometers south. He was on a rooftop. He had been on this rooftop, or one like it, for long enough that his body had settled into the concrete's temperature, his back cold against the ledge where he sat with his legs extended and his arms crossed over his chest. The posture of a man who had fallen asleep refusing to admit he was sleeping.
He sat up. The city spread below in its familiar grid: sodium streetlights casting pools of amber-orange along empty streets, the river a dark seam bisecting the districts, the harbor's industrial cranes standing like sentinels against a sky bruised with light pollution. Miyama to the west, residential, quiet. Shinto to the east, commercial, the neon of a pachinko parlor still burning at — he checked the angle of Orion against the roofline — past two in the morning.
The taste of mud was still in his throat.
He swallowed it down. Not metaphor — sensation. The Grail mud's residue lingered in his incarnated body the way radiation lingers in irradiated soil: not enough to harm, too much to forget. Ten years since the Fourth War had given him this body, pulled him from spirit to flesh through a baptism of concentrated evil, and the taste still surfaced in the hours when his conscious filters dropped. A reminder. The corrupted Grail that had birthed him was not done with this city.
Sha Naqba Imuru was already active.
The clairvoyance operated at the edge of perception: a low-frequency hum beneath thought, feeding data the way a general's scouts feed reports — continuous, layered, requiring attention to separate signal from noise. He had not activated it deliberately. It had been running while he slept, processing the War's opening movements with the systematic indifference of a machine counting casualties.
Seven Servant signatures. He sorted them by intensity and proximity, the way one sorts pieces on a board. The strongest — blinding, solar — was Saber, three kilometers west, her spiritual density radiating through the Emiya boy's bounded field like light through gauze. He catalogued her and moved on. Lancer's signature crouched near the commercial district — a predator straining against a leash, his combat readiness a physical thing even at this distance. Archer occupied a rooftop in the Shinto district; his signature carried an undertone that Sha Naqba Imuru flagged and could not classify, a wrongness beneath the wrongness, a signal inside the signal. Rider was near the harbor, her mana fluctuating in a pattern that suggested instability rather than combat readiness. Assassin was fixed to the mountain — Ryuudou Temple, anchored like a nail driven into the ley line convergence point. The remaining two were distant, partially occluded. One was the Einzbern's weapon; the other he could not place precisely.
Seven Servants. The War's standard complement. The architecture was correct. What filled it was not.
He extended Sha Naqba Imuru deeper — past the surface topology of Servant positions, past the mundane electromagnetic noise of a sleeping city, down into the spiritual substrate where the ley lines carried Fuyuki's mana like blood through capillaries. The ley lines were wrong. He had felt this for months, a growing wrongness that he had initially attributed to Angra Mainyu's corruption — the curse that had infected the Grail since the Third War. The corruption was there, yes: a dark film coating the mana channels, the spiritual equivalent of oil on water. He could taste it from here, faintly, beneath the harbor salt and the cold.
But there was something else.
Beneath the corruption, like a second signature hidden inside the first, a pattern he could not decode. Not Angra Mainyu — that was chaotic, nihilistic, the spiritual fingerprint of indiscriminate suffering. This was ordered. Deliberate. As though something intelligent had examined the corruption's structure and decided it could be used.
Sha Naqba Imuru tried to resolve the second pattern and returned static. Active static — something resisting his clairvoyance, or a signal his clairvoyance lacked the categories to process. Both possibilities were unprecedented. He had catalogued divine beings, cosmic principles, weapons forged before human language existed. His treasury held the prototypes of every noble phantasm in recorded history. Sha Naqba Imuru had never encountered data it could not at minimum categorize.
He withdrew the clairvoyance to its baseline range and sat with the gap in his intelligence like a commander sitting with a blank space on a map marked here be dragons. The blank space did not resolve. It would not resolve tonight.
Below him, a convenience store on the corner of Third and Riverside was still lit — fluorescent white spilling onto the sidewalk where a clerk was restocking shelves visible through the glass. Two streets over, a fishing boat's running light moved on the river, headed downstream toward the harbor, the quiet engine putting of a working vessel on a working schedule that had nothing to do with Servants or Grails or corrupted mana systems. Somewhere in the residential blocks of Miyama, a dog barked once and stopped, and a light came on in a second-floor window and went off again.
He had been watching this city for ten years. The catalogue of its ordinary details had grown without his permission — an inventory assembled by proximity rather than intention, the way dust accumulates on surfaces in a room you do not clean because you do not consider it yours. Shopkeepers. Students. The woman on Seventh Street whose roses bloomed every June despite the salt air and whose patience with the soil exceeded anything he had observed in any king of any era. Night-shift workers at the harbor whose hands moved with a competence that had nothing to do with heroism and everything to do with repetition. The shrine keeper at the Miyama district shrine who rang the bell at six every morning — he had heard it three thousand, six hundred and fifty times.
The catalogue was not affection. It was territory. A king's awareness of what occupied his domain, nothing more. He had told himself this for approximately six of the ten years and had not yet identified when the explanation had stopped being sufficient.
He looked away from the city and tried to focus on the tactical picture. Seven Servants. Corrupted ley lines. An unreadable second pattern. The War was beginning, and it was wrong in a way he could sense but not prove, and no one would believe a word of it from his mouth.
That was when the vision hit.
Not Sha Naqba Imuru's steady data feed — this was something else. A spike driven through the clairvoyance's filters, bypassing his sorting mechanisms, slamming into his awareness with the force of a physical blow. He gripped the ledge.
Fire.
Not the remembered fire of the Fourth War, not the Fuyuki blaze that had consumed five hundred people and given him this body. Future fire. Multiple futures, overlapping, their probability lines converging on a single point the way rivers converge on a delta — dozens of timelines collapsing into one outcome. The city in flames. The sky split open. The ley lines ruptured and bleeding raw mana into the atmosphere like arterial spray. And beneath it all, beneath the fire and the rupture and the collapsing timelines —
Something moved.
It registered not as motion but as awareness. The feeling of being in a dark room and realizing something in the dark was already looking at you. Vast. Not divine — he understood gods; he had defied them, killed them, carried their weapons in his treasury. He understood divine scale the way a mountain climber understands altitude. This was not altitude. This was geology. The mountain itself, aware. The earth beneath Fuyuki shifting its attention toward the surface, toward the damage accumulating above it, and the attention was not hostile or benevolent but something worse — indifferent in the way that gravity is indifferent, a force that operates without opinion.
The vision lasted two seconds. Perhaps three.
Then it broke. The fire collapsed. The convergence scattered. The vast presence withdrew — not retreated, withdrew, the way an eye closes because it has seen enough, not because it has been repelled.
Gilgamesh sat on the rooftop with his hands locked on the concrete ledge and his heart rate elevated by thirty beats per minute and the taste of mud so strong in his throat he nearly spat. His eyes were watering — optic nerves flooding from the vision's throughput, a body trying to process what a body was not designed to hold. He forced his breathing into a controlled rhythm. Four counts in. Four counts hold. Four counts out.
The city below him continued as though nothing had happened. The convenience store clerk finished restocking and leaned against the counter, looking at his phone. The fishing boat had rounded the bend toward the harbor. A car passed on the bridge road with its radio playing something he could not quite hear.
He ran the tactical assessment. Something existed beneath this city that predated the ley lines, the Grail system, the city itself. It was not divine. His clairvoyance could not classify it. The futures he had glimpsed converged on catastrophe, and the catastrophe was connected to the Grail's corruption, and the corruption was being directed by an intelligence he could not identify.
He knew more than anyone in this War. He knew enough to know it was not enough.
The wind cut across the rooftop. He unclenched his hands from the ledge, stood, and surveyed the city one more time. The grid of amber lights. The dark river. The sleeping districts and the quiet streets and the ten years of accumulated ordinary that sat in his memory like ballast in a ship's hold — weight he had not requested and could not now discharge.
A king's assessment: the walls were not thick enough.
He descended from the rooftop through a Gate of Babylon platform — a single golden disc that materialized beneath his feet and carried him to street level before dissolving. The street was empty. He turned north, toward the hill where Kotomine Church sat on its elevation above the city like a confession that no one had asked for. He had lived in that church for a decade. It had never been his.
The night was cold. The War had begun. And somewhere beneath the pavement, beneath the ley lines, beneath everything that mattered or didn't, something was waiting with the patience of stone.
He walked toward the church. He had one last thing to discard before the real work could begin.
