“Censer swinging on your third step, Cato. Don’t drag your hem.” Ilias murmured the instruction through motionless lips, his back straight as an iron rod. The Grand Nave smelled of frankincense and burning rendered fat. Three hundred voices swelled above them in a measured, monotone plainchant, echoing off ribbed vaults forty cubits high. Ahead, framed by twenty-four silver candelabras, sat the Great Tabernacle of Saint Vossen. Inside it rested the Heart. Cato swung the brass thurible with mechanical rhythm. Smoke billowed out, white and dense, scented with dried verbena. Underneath the hem of his tunic, his skin prickled where the lead-glass replica pressed against his ribs. He had spent eighteen hours engraving its facets with a miniature lattice of refraction runes, calibrated to bounce the ambient glow of the altar candles. If the geometry held, it would look like burning gold for roughly twenty minutes. “The celebrant turns at the third verse,” Cato whispered back, his eyes locked on the crimson silk robes gathered atop the marble dais. “You take the left dais steps. Keep the choristers’ angle blind.” “May the heavens forgive us,” Ilias muttered. “Because if we fail, the inquisitors will flay us before sunset.” “Faith won’t steady your hands, Ilias. Friction will. Grab it by the base.” The choir rose into the crest of the hymn. The presiding elder, an ancient man bowed under twenty pounds of gold embroidery, extended his palms toward the congregation and closed his eyes in ceremonial ecstasy. Now. Cato took two long, brisk strides past the brass railings. Ilias moved in tandem, sweeping his wide choir sleeves out as if adjusting a devotional cloth on the lectern. The broad silk created a four-second blind spot between the choir stalls and the tabernacle grill. Cato’s fingers slipped into the grill’s cold copper-latticed fretwork. His knuckles grazed the iron pin holding the grate shut. With a tiny, practiced twist of his thumb, he discharged a minuscule static charge directly into the locking cog. The metal expanded a fraction of a millimeter, slipping the catch without a click. His hand darted into the hollow. The real relic was warm. Not the warmth of consecrated blood or divine fire—it felt like a copper boiler running a low simmer. He pulled it free, slid it into his deep linen sling, and swapped in the lead-glass fake with one fluid motion. The grate swung shut. The pin settled. Ilias let his sleeves drop, his knuckles gray from tension. He stepped backward into line just as the choir reached its concluding chord. The elder lowered his arms, bowing low toward the altar. The replica behind the metal lattice gleamed with stolen candlelight, shimmering like an unblemished jewel. Cato turned, keeping his chin tilted toward his chest, and followed the slow procession out through the north cloisters. *** They didn't speak until they reached the disused sub-vault beneath the old distillery, two floors below the seminary cellars. Cato barred the heavy timber door with an ash plank, then collapsed onto a crate of rotting vellum. “We did it,” Ilias said. He slid down the wall until his knees hit the dirt floor. He pulled at his collar, choking down dry air. “By the saints, we actually did it. If anyone saw—” “No one saw,” Cato said. He pulled the relic from his robes and placed it on the battered workbench between two tallow lamps. “Bring the loupe.” Ilias scrambled up, bringing the brass magnifying lens over. His reverence had not faded; he reached toward the object with trembling fingertips, then stopped short, terrified of profaning it. “It is… the Heart. The very spark that founded the realm.” “Look closer,” Cato said. He rubbed the soot off the exterior with an oiled cloth. The outer casing was not beaten gold. It was a seamless gold-plated alloy, polished to an impossible tolerance. There were no hammer marks. No tool slips. No signs of human artisanal craft. Along the seam ran microscopic channels, thinner than horsehair, filled with a blue-gray ceramic compound. “What are these runes?” Ilias squinted through the loupe, his brow furrowing. “This isn't ancient liturgy. It isn't even high dialect. There are no invocations to the flame. Just… numbers? Parallel bars?” “They aren't runes,” Cato whispered. A cold realization washed away his academic pride. “They’re circuit traces.” “Circuit?” “It’s a capacitor. A solid-state energy storage unit.” Cato tapped the base. “Look at the junction here. That’s not a sacred seal. It’s an inductive charging port. The entire high altar… it isn't receiving prayers. It’s an induction pad. The church has been charging a battery for five hundred years and calling it divine favor.” “You are speaking madness,” Ilias said, his voice rising, cracked with sudden panic. “It is a miracle. It must be!” “Look at the serial stamp, Ilias!” Cato shoved the loupe directly into his hands, pointing at the base. “Read the glyphs. Don't interpret them as holy pictograms. Read them as phonetic sounds!” Ilias stared through the glass. His lips twitched as he sounded out the stamped Latin characters: “P… R… O… J… E… C… T…” Cato pressed his bare thumb against the recessed groove near the contact pins, searching for a discharge release to harvest the frequency they needed for the dying boy. The moment his skin completed the circuit, a high-frequency whine pierced his ears. The basement vanished. There was no transition, no spell-light, no chant. Reality tore open, throwing Cato into blinding fluorescent white. The smell hit him first: ozone, floor wax, sterile air conditioned to sixty-six degrees. He was standing in a high-ceilinged room filled with stainless steel consoles. People moved around him in cleanroom suits and white lab coats, speaking in calm, urgent voices over the steady hum of industrial cooling fans. A massive glass partition separated the control room from a vacuum chamber where an identical golden cylinder sat suspended inside a titanium ring. “Containment pressure is holding at zero-point-nine,” a woman’s voice crackled through an overhead intercom. “Core decay is arrested.” “Run the boot sequence,” an older man answered from a central terminal. His face was lined with exhaustion. He tapped a mechanical keyboard, the plastic clatter brutally familiar to Cato’s Earth-born soul. On the central monitor, green text scrolled rapidly down a black CRT display: `ATMOSPHERIC SEEDING: COMPLETE` `GENETIC PURGE STAGE 4: STABLE` `PROJECT VOSSEN: SYSTEM REBOOT INITIATED` `ARCHIVE MODE: MYTHOLOGICAL ENCODING ACTIVE` “Will they remember?” the woman asked softly. “No,” the man said without looking up. “If they remember how we burned the atmosphere, they’ll rebuild the engines and do it again. Give them priests. Give them prayers to maintain the filters. Ignorance is the only cage that holds.” The room flashed red. A terminal alarm shrieked. Cato gasped for air and tumbled backward onto the cellar floor, knocking over a flask of spirits. Glass shattered around him. “Cato!” Ilias grabbed his shoulders, hauling him upright. “Cato, speak to me! Your eyes went dead!” Cato sat on the cold earth, chest heaving, his fingers clawing at the dust. His breath came in ragged, desperate pulls. It wasn't a fantasy world. It was never a realm of gods and miracles waiting for a clever scholar to introduce natural law. It was a terrarium built out of the ashes of his own world, wrapped in superstitious chains by people who thought humanity was too dangerous to have real tools. “This isn't magic,” Cato whispered, staring at his palms in pure horror. “It’s a restart button. We’re living in a quarantine zone.” “What are you saying?” Ilias demanded, shaking him. “What did you see?” Before Cato could speak, a deafening blast tore through the upper levels of the seminary. The ground shook violently, raining stone dust and mortar onto their heads. Far above, the great bronze bells of the cathedral began to toll—not the slow, solemn ring of prayer, but the rapid, terrifying clangor of the iron ward-bells. A horn blared from the courtyard, followed by the roar of hundreds of voices. “The altar,” Ilias breathed, his face draining of color. He looked up at the trembling ceiling. “The false relic… the light lattice collapsed.” Heavy iron boots thundered down the stone corridor directly outside the cellar door. A voice like grinding stone echoed down the hall, amplified by an inquisitor’s throat-rune. “Seal every gate! The Heart has been violated! Bring the pyres to the courtyard—by decree of the High Prelate, nobody leaves the Luminarium alive!”
