The old tax cellars did not feel like a place built for people.

Arthur understood that the moment he descended the stone steps beneath the customs house. The ceiling pressed low. Damp gathered on the walls. The air smelled of mold, old wax, rusted metal, and something sour that had lived too long without sunlight. Shelves lined the room in uneven rows, some new, some old enough to lean like tired men. Lead tags hung from cords. Wax tablets lay beneath cloth. Broken amphorae stood in corners with faded marks scratched into their clay.

Rome kept everything.

Taxes. Debts. Names. Lies.

Men.

Marcus went first with his sword drawn. Arthur followed with the lamp. Milo came last, whispering prayers so quietly Arthur could not tell which god he was disappointing.

The black box was gone.

They had seen it carried through the side passage only minutes earlier. Lupo had followed it into the night, alone, because someone had to. Arthur hated that decision already. He hated most decisions that survived more than ten seconds.

But the cellars still mattered.

If the box held the newest records, the shelves might hold what was left behind. Old tags. Broken tablets. Forgotten scraps. Rome’s crimes were often preserved by Rome’s laziness.

Blue light flickered.

Emergency Mission Active.

Recover Source Evidence.

Time Remaining: 00:48:12.

Known Risk: Hostile presence nearby.

Recommended Action: Extract records. Avoid engagement.

Arthur almost laughed.

Avoid engagement.

As if engagement were something one scheduled politely.

Milo pointed with a trembling hand. "Source bundles were there."

Arthur lifted the lamp.

The shelf Milo indicated was half-empty. Cord marks remained in the dust. Someone had taken the newest bundles first and left the older ones scattered. A tablet lay cracked on the floor. Two lead tags had fallen beneath a shelf.

Too late.

The words formed in Arthur’s mind before he could stop them.

Marcus saw his face. "No."

Arthur looked at him.

Marcus nodded toward the floor. "When thieves hurry, they leave things."

That was true.

Arthur crouched. His injured fingers ached as he reached under the shelf and pulled out the first lead tag. It was stamped with a number, a category mark, and a faint crescent. The second tag had initials. The third, half-buried in dirt, carried a small dolphin.

The same symbol as the woman’s pin.

Arthur’s pulse quickened.

"Milo."

The runner crouched beside him.

"Read."

Milo wiped dirt from the tablet fragment and held it near the lamp. His eyes moved quickly, then stopped.

"What?" Arthur asked.

Milo swallowed. "Debt conversion. Twelve units. Blue warehouse code. Transfer pending."

"Receiving mark?"

Milo looked at the dolphin tag.

"Aemilius Celsus household."

Not Decimus Celsus.

Never directly.

But his household.

Clean hands. Dirty rooms.

Arthur wrapped the tags in cloth and pushed them into his pouch.

Blue light flickered again.

Source Evidence Fragment Recovered.

Buyer Network: Partially Exposed.

Evidence Chain: Incomplete.

Recommended Action: Continue search.

Arthur looked at the shelves.

Continue search.

The system made courage sound like administration.

He moved deeper into the cellar. Marcus stayed close, listening to the stairs. Milo found a narrow niche between stone and wood where runners had once hidden messages or bribes. Inside were two damp tablets, warped but readable enough to matter.

One listed names. Not full names, but more than the blue ledger had given them.

One listed categories.

Debt labor.

Temporary holding.

Private repair crew.

Granary work.

Arthur stopped.

"Granary?"

Milo looked over his shoulder. "Maybe. The word is storage. Grain storage, I think."

Arthur tucked the tablet into his tunic with the others.

A sound came from above.

Marcus raised one hand.

Everyone froze.

Footsteps.

More than one man.

Coming down.

The lamp at the top of the stairs brightened, casting long shadows over the stone. Arthur’s body went cold. There was no rear exit. No convenient second stair. No window. The cellar had one mouth, and men were coming through it.

Marcus moved to the base of the stairs.

"Stay behind me," he said.

Arthur did not argue.

The first guard came down with a lamp in one hand and a baton in the other. He saw Marcus too late. Marcus struck him with the hilt of his sword, hard enough to fold him against the wall. The lamp fell and shattered, oil spreading across the step.

The second man shouted.

Marcus kicked the fallen lamp upward. Flame licked across spilled oil. Not enough to burn the building. Enough to make the second man stumble.

A third voice shouted from above.

Milo grabbed Arthur’s sleeve. "We should go."

Arthur looked at the shelf beside him.

More tags.

More names.

More proof.

"One more."

Milo stared at him as if he had gone mad.

Arthur probably had.

He reached for the bundle.

The second guard came through the flame faster than Arthur expected. He carried a short knife instead of a baton. Marcus turned to meet him, but the first guard, not fully unconscious, grabbed Marcus by the ankle.

Everything happened at once.

Marcus kicked free.

The second guard slipped past him.

Arthur saw the knife.

He stepped back and hit the shelf behind him.

The shelf did not move.

The guard came forward. 𝚏𝗿𝗲𝐞𝚠𝕖𝐛𝗻𝗼𝐯𝕖𝚕.𝚌𝗼𝗺

Arthur lifted the lamp like an idiot. The guard struck it from his hand. It hit the floor and rolled, throwing mad light across the walls.

Milo shouted.

Marcus tried to turn, but the narrow stair held him between two men.

Arthur was alone.

The guard shoved him against the shelf. Pain cracked through Arthur’s shoulder. The knife rose.

For one second, Arthur saw it clearly.

Not as part of a plan.

Not as history.

Not as Rome.

Just metal, close enough to end him.

Then the system changed color.

Not blue.

Red.

HOST STATUS: CRITICAL.

Fatal Injury Probability: 94.8%.

Primary Directive Conflict Detected.

Host death will terminate active mission.

Emergency Override Initiated.

Arthur’s breath caught.

The knife came down.

Military Authority Access Requested.

Processing...

Processing...

Access Denied.

Arthur stared.

Even now?

"...seriously?"

Secondary Emergency Function Available.

Temporary Tactical Overlay.

Duration: 9 seconds.

Compatibility Strain: Severe.

Accept?

Arthur did not think.

Yes.

The cellar fractured into lines.

Not visions. Not magic fire. Not strength.

Angles.

Distances.

The guard’s wrist became a red line. The loose shelf peg behind Arthur glowed faintly. The broken lamp on the floor pulsed yellow. The knife’s path appeared a heartbeat before it moved.

Arthur’s body reacted late, but not too late.

He twisted. The blade missed his throat and cut across his upper arm instead. Pain flashed hot and bright. Arthur slammed his shoulder into the loose shelf peg. The old wood shifted. A row of lead tags and tablets crashed down between him and the guard.

The man stumbled.

Arthur kicked the broken lamp.

Oil splashed beneath the guard’s sandal.

The guard slipped.

Marcus arrived like a door being broken by a storm.

He caught the guard from behind and drove him into the shelf hard enough to make the whole row shudder. The knife fell. Marcus kicked it away.

Arthur slid down the wall, clutching his arm.

The red overlay vanished.

The world returned in damp stone, smoke, and pain.

Milo grabbed the fallen tags with both hands. "You are bleeding."

Arthur looked at his arm. The cut was ugly, but not deep enough to kill him.

"Not as much as I expected."

"That is not comforting."

Marcus stood over the guard, breathing hard. "Can you move?"

Arthur nodded.

Then the system broke.

The red text shattered into static.

For a moment, the cellar disappeared.

Arthur was not in Ostia.

He stood under a sky the color of blood and dust. Thousands of hooves shook the earth. Men screamed in a language he did not know. Black banners snapped in a hard wind. Far ahead, a fortress burned, and before the flames stood a single figure in dark armor, mounted on a horse with a mane like smoke.

The figure turned.

Not slowly.

Not by accident.

He looked directly at Arthur.

Across distance.

Across time.

Across something Arthur did not have a word for.

A voice cut through the roar, cold and startled.

"...Rome has awakened?"

The vision vanished.

Arthur hit the cellar floor on one knee.

Milo shouted his name.

Marcus grabbed his shoulder. "Arthur!"

Arthur gasped.

The cellar was back. Smoke. Stone. Blood. Footsteps above. Real danger. Immediate danger.

Blue light flickered, unstable and broken around the edges.

Unknown Civilization Core Contact Detected.

Synchronization Attempt: Failed.

Record Sealed.

Access Level: Insufficient.

Arthur stared at the words until Marcus shook him once.

"Move."

Arthur moved.

They ran.

Marcus took the stairs first, sword drawn. Milo followed with the recovered tags and tablets clutched against his chest. Arthur came last, one hand pressed to his bleeding arm. The men above had pulled back from the smoke but had not fled. Marcus hit one with his shoulder and sent him into the wall. Milo ducked under an arm and nearly dropped the evidence. Arthur grabbed him by the back of the tunic and pulled him through.

They burst into the service corridor and ran without dignity.

Someone shouted from the front room. Another voice called for the rear door. Milo led them through a storage room, under a hanging cloth, and out a low window into a yard stacked with amphorae. Arthur landed badly and nearly fell.

Marcus hauled him upright.

"Still alive?" Marcus asked.

"Against several recommendations."

"Good."

They ran again.

The streets blurred into darkness, walls, corners, breath, and the slap of sandals against stone. Once, Arthur thought he saw a gray cloak at the end of a lane. Marcus dragged him through a side gap before he could be sure.

By the time they reached Crispus’s storage room, Arthur’s lungs felt scraped raw.

Felix opened the door before they knocked.

His eyes went first to Arthur’s bleeding arm.

Then to Marcus.

Then to Milo.

"Where is Lupo?"

Arthur’s stomach dropped.

"He is not back?"

Felix’s face answered.

They entered. Crispus barred the door. Naso was standing now, Marilla awake and clinging to his tunic. Duro was there too, which meant the annex distraction had ended or failed or both.

Arthur put the cloth bundle on the table with shaking hands.

"Partial records," he said. "Aemilius household. Debt labor. Transfer marks. Maybe granary work."

Naso stared at the tags as if they were ghosts.

Crispus leaned over them. "Dolphin mark."

"Household," Arthur said. "Not Celsus directly."

"Of course not," Crispus muttered. "Clean men hire dirty hands and call it distance."

The door opened behind them.

Lupo stumbled in.

Blood ran down his left arm.

Felix caught him before he fell. Duro moved to the door, looking past him into the alley. Marcus stepped beside Duro, sword already half-drawn.

No one followed.

Felix lowered Lupo onto a crate. "Where?"

"Shoulder," Lupo gasped. "Knife. Small one. Bad aim."

Marcus checked the wound quickly. "Lives."

"Wonderful," Lupo said through clenched teeth. "I was worried."

Arthur crouched in front of him. "The box?"

Lupo closed his eyes for one breath. When he opened them, the grin was gone.

"They took it to a private house."

Crispus went very still. "Where?"

"Near the temple of Vulcan. Red door. Painted lintel. Two lamps outside. Men with clean sandals."

Crispus cursed softly.

Felix looked at him. "Rich?"

"Rich enough to hate noise," Crispus said.

Arthur looked down at the lead tags on the table.

They had not recovered the box.

They had not saved the full source records.

But they had fragments. Names. Marks. Proof that the movement led beyond the warehouse, beyond the registry, beyond men like Naso.

Toward households.

Toward wealth.

Toward people who never touched rope, knives, or chains.

Blue light flickered.

Source Evidence Partially Recovered.

Buyer Network: Partially Exposed.

Evidence Chain: Incomplete.

Ostia Influence Anchor: Threatened.

New Objective: Recover Black Box.

Arthur read the words in silence.

Then another line appeared.

System Log Updated.

Emergency Tactical Overlay: Expended.

Compatibility: 13%.

Military Authority: Locked.

Unknown Civilization Core: Classified.

Arthur stared at the last line.

Unknown Civilization Core.

Not host.

Not enemy.

Core.

Marcus was watching him.

"What did you see?" he asked quietly.

Arthur looked at the tags, the blood, the sleeping child, and the black door waiting somewhere near Vulcan’s temple.

He almost told him.

Then he heard the voice again.

Rome has awakened?

Arthur closed his hand over the broken tablet.

"Something bigger than Celsus," he said.

Marcus’s face did not change.

But his eyes did.

Outside, the port moved toward dawn, and Arthur understood for the first time that saving Rome might not mean fighting only Rome’s enemies.

It might mean fighting whatever had noticed Rome waking.
