The corridor was carved from a single, unbroken vein of obsidian so dense that light died against its surface. No torches. No crystal lamps. The only illumination came from the liquid mana circulating through the Vanguard guards’ armour, their crystalline veins pulsing a dim, rhythmic blue that cast warping shadows across the walls like veins seen through skin.
There were five of them ahead of Eshiren. Five behind. He walked in the very center of the formation, the guest position, the unfamiliar variable slotted into a machine that had been running with lethal precision for decades.
None of them spoke.
They didn’t need to.
The probing started thirty paces into the corridor. Eshiren registered it as a subtle pressure shift against the surface of his core, a featherlight brush of Dragon mana, almost polite in its precision, sliding across his external defenses like fingers testing the thickness of a wall. The guard two steps to his left. Domain-stage, at minimum. Testing whether the new blood’s core had the density to justify his placement here, or whether the decree from the Eighteenth Seat had elevated a fraud.
Eshiren gave the probe nothing. He kept his fused core locked tight, the two halves compressed against each other in a flat, unremarkable hum that mimicked the baseline output of a standard Dragon-born soldier. His Ohn-Thari half he buried so deep inside the marrow of his spine that it would take a surgical extraction to find it. His face he kept empty. Neither hostile nor submissive. Just a wall of absolute nothing, a blankness that made predators hesitate, because blankness in a combat zone usually meant one of two things: idiocy or lethality.
The probe withdrew. A second one followed, from behind. Heavier. Less courteous. This one didn’t slide—it pressed, a blunt fist of mana testing whether Eshiren’s core would crack under direct contact. He let the fist land, absorbed the impact into the Dragon half of his fused core without flinching, and let the attacker feel the sheer, dense mass of fire-mana packed behind his ribs.
The pressing stopped.
Twelve more paces. No further tests. The formation moved in silence, boots striking obsidian in perfect synchronization, a rhythm Eshiren matched within three strides, slotting himself into the cadence as if he had been born to it.
The corridor terminated in a set of doors.
They were not doors in any sense Eshiren had previously understood the word. Two slabs of adamantine alloy, each one thick enough to serve as a blast wall for a planetary defence battery, standing eight times the height of a man and carved with Vreth’kaan glyphs so deeply etched that Eshiren could have laid his arm inside the channels. The glyphs radiated a constant, low-frequency vibration that bypassed his eardrums and settled directly into his jaw, making his molars ache.
The lead guard placed his palm against the door’s surface. A pulse of mana. The adamantine groaned, split down the centre, and the two halves swung inward on hinges that must have been designed by siege engineers.
The cold hit Eshiren like a wall of knives.
He had prepared for intensity. For the mana density, for the gravity, for the political hostility. He had not prepared for the temperature of the Absolute Room to be cold enough to kill an unprotected man in minutes.
The air inside the throne room was a physical force. Each breath stabbed into his lungs like inhaling ground glass suspended in ice water. Frost crystallized on the fine hairs of his forearms within seconds, and his fingertips went numb before he had crossed the threshold. The moisture in his nostrils froze. His blood, sluggish and thick from the planet’s ambient mana density, began to slow.
The Vanguard guards walked through it without visible reaction. Their armour’s crystalline veins pulsed brighter here, the liquid mana circulation generating enough internal heat to keep their bodies functional. Standard kit. Standard protection.
Eshiren did not have Vanguard armour. He wore his Shadow Blade combat fatigues—engineered for Azarian desert warfare, insulated for heat rejection, not thermal preservation.
He was going to freeze to death on his first shift.
Unless.
The fused core kicked behind his sternum. He opened the Dragon half a fraction, a calculated, desperate fraction—and routed fire-mana through his own arterial walls, wrapping his organs in a thin layer of internal combustion that raised his core temperature just enough to keep his blood flowing. The Ohn-Thari half he kept compressed and silent, a cold star hidden behind a furnace. The balance was excruciating. Too much heat and the guards would sense the output differential. Too little and his extremities would blacken.
He walked. Did not shiver. Ground his teeth behind closed lips until the enamel protested.
The Absolute Room opened before him. It was vast, a cathedral hollowed from the interior of Earthgon’s megastructure, the ceiling so far above that it disappeared into darkness. The walls were raw obsidian polished to a mirror-finish that reflected nothing, as though light entered the stone and simply chose not to come back. The floor was a single slab of unbroken adamantine, inscribed with concentric rings of Vreth’kaan script that spiralled inward toward the room’s centre.
At the centre of the spirals sat the throne.
And on the throne sat the God.
Eshiren’s fused core lurched. Both halves. The Dragon mana surged toward the Emperor like iron filings dragged toward a lodestone, straining against Eshiren’s control with a desperate, animal need to submit. His Ohn-Thari half recoiled in the opposite direction, burrowing deeper into his marrow, retreating from the presence the way a candle flame retreats from a hurricane.
Kzar-Gorthennakk, the Eighteenth Dragon God, did not look up.
He sat motionless on a throne grown from the fused vertebrae of his seventeen predecessors—a column of ancient, calcified bone spiralling upward behind his shoulders like a twisted spinal cord reaching for heaven. His armour was not armour. It was his own body, the surface of his skin having long since calcified into dense, crystalline scales the colour of deep space. His eyes were open, fixed on a point somewhere beyond the walls, beyond the planet, beyond reality itself, processing calculations that operated on a scale Eshiren could not comprehend.
The God did not breathe.
The room breathed for him. A slow, rhythmic expansion and contraction of ambient mana, pulsing outward from the throne in waves that pressed against Eshiren’s chest like the tidal pull of a neutron star. In. Out. In. Out. Each pulse carried a weight that made Eshiren’s bones groan.
He took his position along the wall. Stood at attention. Counted the pulses. Twelve per minute. Consistent. Mechanical. The heartbeat of a world.
An hour passed. Then two. Krazmakor arrived for a scheduled briefing, flanked by his own attendants, and the Prince’s terror filled the frozen room like smoke.
His ice-blue eyes, locked forward, rigidly controlled, scanning the adamantine floor as if it contained the secret to survival. His spine was so straight it looked fused. He knelt before the throne and presented his post-expedition report in a voice that only someone listening for the fracture would have heard waver on the consonants.
The Emperor spoke once during the entire briefing.
"The Threnn-Kzari reserves on Voskarak are declining at four percent per cycle. Reduce the vassal population by thirty percent. Reallocate the surplus mana to the Seventh Carrier Fleet."
That was the sentence. Thirty percent of Voskarak’s population—hundreds of thousands of souls, converted into fuel for a war-galleon with one flat, measured statement. No anger. No cruelty. Just arithmetic.
Krazmakor’s left hand trembled.
Eshiren shifted his weight. One degree forward. A subtle lean—the predatory tilt of a handler reminding his charge that weakness was visible. Krazmakor caught it from the periphery. The tremor stopped. The Prince dipped his head and said, "It will be executed, Eighteenth Seat."
The guards along the wall registered the exchange. Instead of words, with the fractional tightening of their stances, the microscopic adjustment of their gazes. They had catalogued the dynamic: the new Shadow Blade controlled the First Heir like a leash controlled a war-beast.
Good. Fear of his authority would buy him time. Maybe enough.
The shift ended after six hours. The adamantine doors groaned open, and the Vanguard filed out in the same precise formation they had entered. Eshiren’s fire-mana reserves were at forty percent. Six hours of constant internal heating without Vanguard armour had cost him more stamina than a full day of combat.
He needed to reach his assigned quarters, recalibrate his core balance, and,
"Eshiren Vesh."
The Vanguard Commander’s voice came from behind him, flat and measured. Eshiren stopped. Turned.
The Commander stood in the antechamber with his arms clasped behind his back. His molten-iron eyes held no anger. No resentment. They held something worse—the cold, patient scrutiny of a man who processed threats the same way his master processed vassal populations.
"Your personnel file lists your biological origin as Gorrakh-born commoner, conscripted through the Academy devshirme and field-elevated by combat citation." The Commander recited it the way a surgeon recites a patient’s chart before cutting. "No pre-conscription core sample exists. No deep-tissue genealogy scan on record. Your entire biological history prior to induction is a bureaucratic void."
Eshiren kept his breathing steady. One count in. One count out. The Dragon half of his core held flat. The Ohn-Thari half pressed against the base of his skull, a cold knot of gold buried under layers of fire and silence.
"A void," the Commander continued, "is a statistical risk. A statistical risk in the proximity of the Eighteenth Seat carries a fourteen percent probability of catastrophic outcome within a standard operational cycle. I do not accept fourteen percent."
He stepped aside. Behind him, standing against the corridor wall with the quiet patience of a tradesman waiting to perform routine maintenance, was a medical operative. Female, Dragon-born, wearing the sterile white uniform of the Imperial Biological Corps. In her right hand she held a deep-core extraction needle, a three-inch spike of crystallized bone designed to pierce the sternum and withdraw a sample of raw, undiluted mana directly from the cultivator’s core.
One sample. That was all it would take. The Ohn-Thari signature threaded through his fused core would light up the extraction readout like a signal fire on a moonless night. Golden mana. Human mana. The blood of the conquered race, circulating inside the Emperor’s personal guard.
"Submit to the scan," the Commander said. "Standard protocol. Thirty seconds."
The needle caught the dim light of the corridor. Eshiren stared at it. His teeth pressed together until his jaw ached.
Thirty seconds to prove he was something he was not.
