A Hammer at the Door

The human had brought a hammer to a library older than his language.

Ivara watched him from beneath the broken arch, holding herself still with one hand against the stone. His lamp moved across the sealed doorway in ugly white rectangles. Each time he struck the chisel, pale fragments drifted down onto the anemones growing between the floor tiles.

The Ninth Archive had survived wars, earthquakes, and a century of royal neglect. Apparently it was going to meet its end beneath a man who could not recognize a hinge.

She uncoiled her current hook.

Above the human's helmet, a cable disappeared into darkness. Another ran from his belt to a drilling frame fixed against the archive wall. The frame was new. Its teeth were not.

Ivara knew those teeth. Three days ago, one had been lodged in the gill of a silver ray she had tried and failed to save.

She moved.

Her tail drove her across the courtyard before his lamp could turn. The hook caught his equipment tether, and she twisted it around a stone finial. He dropped the hammer. She seized his wrist and pressed it against the wall, keeping his hand clear of the valve at his throat.

People who threatened archives deserved arrest. They still needed to breathe.

He looked at her through the helmet glass.

He was younger than she expected. Dark hair floated against his forehead, badly cut, and an angry red mark crossed the bridge of his nose. His surprise lasted barely a second. Then he pointed past her shoulder.

She tightened her grip.

"No," she said in the traders' tongue. "We are finished with pointing at valuable things."

The speaking plate beneath his chin clicked. His voice emerged through water, stripped of its breath but not its urgency.

"The frame. Its cutter is still turning."

She glanced sideways.

The drill's central spindle rotated with terrible patience. Its teeth had reached the first ring of the tide sigil.

Ivara released his wrist and struck the frame's power cable with her hook. The woven armor resisted. Of course it did. Surface engineers protected equipment better than anything the equipment encountered.

The human pulled a knife from his boot.

She swung toward him.

He held the blade flat against his own palm, showing her its edge, then pointed at the cable.

"Ceramic," he said. "It will cut the braid."

"Give it to me."

He did. His fingers opened without hesitation, and for a beat she looked at his hand instead of the machine. Strong hands, scraped knuckles, no attempt to close around hers. She disliked noticing the distinction while an ancient door was being destroyed.

She severed the cable. Light flashed inside the frame. The spindle stopped with a tooth buried in the outermost line of the sigil, and the sea went briefly, unnaturally still.

No drifting silt. No pull against her fins. Even the loose end of the cable hung as though someone had drawn it on glass.

Then the courtyard lurched sideways.

The human slammed against his tether. Ivara caught the edge of the doorway as a current tore through the arch, carrying shattered coral and a cloud of bright startled fish. A crack opened across the sigil. From inside came a sound like a thousand people taking one breath.

She tasted iron.

Not blood. Old binding mineral, dissolving into the water.

"What did you do?" she demanded.

"I arrived after it started."

"Convenient."

"Not particularly. Six of my crew are on the other side."

He pointed at the doorway again. This time she looked closely enough to see the cut ends of another guide cable disappearing through a narrow gap. The drilling crew had entered an antechamber when the first plate lifted. The plate had come down again.

Ivara's anger did not lessen. It acquired an inconvenient additional task.

She swam to the lower inscription and brushed sediment from the characters. Her grandmother had taught her this script by tapping the syllables against her wrist during long journeys. Official lessons had come later, along with official advice about which passages were unsuitable for public study.

The instruction beneath her fingers was simple. Restore balance before opening.

"There should be a second machine," she said. "Somewhere above this one."

"On the shelf. Twenty fathoms up."

"Is it running?"

He looked at the cable she had cut. "Yes."

"Then signal them to stop."

He reached for a brass switch at his hip and tapped it three times. A tiny red light answered. He tapped again. No change.

"They've disconnected my command line."

She stared at him.

"I told the expedition director the permit didn't cover an occupied site," he said. "He disagreed with the word occupied."

There it was: a familiar small word used to make a large theft respectable.

"Someone has to stop the second machine," Ivara said. "I'll go."

"You'll need the knife."

She already had it. He seemed to notice at the same moment and gave a short, humorless nod.

She secured his tether to a higher rung, safely above the broken arch. "Stay."

"Where exactly did you think I would go?"

Ivara surged upward. The shelf emerged through a curtain of disturbed sediment. A second frame crouched on its edge, unattended, pouring stolen current into a cylindrical storage vessel. She cut its cable and opened the manual release before pressure could split the vessel.

The released water punched her backward.

For a moment she could see nothing. Stone scraped her shoulder. She found a handhold by touch and waited for the world to return in fragments: lamp glow below, a ribbon of bubbles, the human's pale face behind glass.

He was still on his tether. He had also fastened the loose archive plate to a second line, preventing it from crushing the guide cable beneath.

Useful did not mean innocent. She reminded herself of that while accepting the loose line he offered.

Together they hauled the plate clear.

Beyond it, six lamps flickered in a flooded vestibule. The trapped divers raised their hands. One lay motionless, held upright by two others.

"Etta," the human said into his speaking plate. The steadiness had left his voice. "Etta, look at me."

A woman's gloved hand lifted an inch.

Ivara guided the first diver through the opening. When the current tried to take him, she caught his harness and pushed him toward the ascent line. The others followed one at a time. The human went last, helping the injured woman until her companions could take her weight.

Then he turned back to Ivara.

"Thank you."

She fastened her arrest cord around his equipment belt.

"Your crew may leave. You may explain."

He looked at the cord, then at the damaged sigil. "Rowan Keir. Surveyor."

She knew the name.

Every map distributed by the expedition bore it in elegant black letters, immediately above the company crest.

"Ivara Sen," she said. "Keeper of what your map called an uninhabited ruin."

His face changed.

"Ivara," he repeated, placing the stress correctly. Most surface visitors never bothered. She wished he had got it wrong; an enemy with no redeeming details would have been much easier to escort home.

Behind them, letters began to shine across the cracked seal. Their light moved over the human's helmet, the fallen hammer, and the archive threshold where generations of her family had stood guard.

WITHDRAWAL FROM THE FIRST RESERVOIR CONFIRMED.

Below that, a second line appeared.

REMAINING CONTAINMENT: EIGHT.

Ivara had studied the seal for twenty years. Nobody had told her it was counting down.
