The opening was not a gentle thing. Her body had been built over a week of human meals, seven days of Kareem’s training, and one week of being a girl with a heartbeat to handle the volume of mana that Iron rank required.

The volume now arriving was the volume Bronze rank required. Pain bloomed at the base of her ribs. She accepted it.

The pain inside her was a small thing compared to the pain she had carried in the spider chamber the day the young master had cut her in half with a clean blade.

The pain was a small thing compared to the heat of the goddess pouring into her on the night she had been born.

The pain was a price. She had paid prices before. She paid this one without flinching.

The Apocalypse core descended. It moved with the patience of rotation. It did not rush. It crossed the distance between the air above her head and the crown of her skull, and when it touched her, it did not stop.

It passed through the bone of her skull as if the bone had been waiting to step aside for it. It traveled down through her, through the soft column of her throat, and through the cavity of her chest.

It came to rest, at last, at the base of her Iron core in the empty bed of channels her body had cleared for it.

The two cores met. For one second, the chamber went quiet. The violet-black column above the pedestal narrowed.

The runes on the walls dimmed by a fraction. The spectators in the second tier registered the change and held their breaths in the same beat.

Then the cores aligned. The Bronze core seated itself underneath the Iron core, and the Iron core lowered itself onto the Bronze core.

The two of them, which had been built to fit together in this exact way, slid into a single configuration with a sound that was not a sound but registered in the chamber as one anyway.

A long, low note. Half hum. Half bell.

The note traveled through the stone of the floor, through the walls, through the obsidian, and into the silver runes. The runes answered with a brightening that was not the brightening of absorption. It was the brightening of recognition.

The implantation was complete.

Ayla’s eyes opened. They were not gold. The gold of her irises had been replaced for the moment of the alignment by a deeper color that the chamber had not yet seen on a human face. The two pupils inside each iris had widened.

The Twin Lens of the Weaver, which had been folded behind her sight since the day in the Devourer’s brain, had opened in response to the change in her body’s mana.

She blinked once. The gold returned. The deeper color receded behind it. The two pupils shrank back to a size that, at the spectators’ distance, could be mistaken for the standard arrangement of a human eye.

The chamber exhaled.

Roric, at the edge of the safety zone, exhaled with it. His hand had been resting at the grip of his sidearm without his having noticed when it had moved there.

He let his hand fall to his side. The first stage was complete. The second stage was the one the witnesses had come for.

The Apocalypse core inside her began to spin in the opposite direction. The slow rotation reversed itself, and as it reversed, it pulled.

The pull was the call her grandfather had described. "

Make your trait call for the core."

Ayla felt the pull reach the catalogue at the back of her mind. The catalogue, which had grown over the last two weeks from a single shelf into a wall of shelves, presented itself to the call in the way a librarian presented a collection to a reader.

Each trait on each shelf stirred. Each one wanted to answer.

Pyromancy rose first. The trait had been with her the longest. The trait had carried her through the spider chamber, the tunnel, the goblin horde, Kareem’s training floor, and the registration platform.

The trait wanted to be chosen.

Bloodnet rose second. The threads had ended more fights for her than any other trait in her catalogue. They sat in her hand the way a tool sat in the hand of a person who had used the tool every day for years.

They wanted to be chosen.

Shadow Stride rose third. The trait that had saved her life. The trait that had let her appear behind a Warrior Hobgoblin and place her hand against the back of its skull without the Warrior ever knowing she had moved.

The trait that had carried her through the bat chamber.

The trait wanted to be chosen.

Acid Synthesis rose. Bone Density rose. Eight Wing Transformation rose. Iron Will rose. Wind Walker rose. Life Link rose. Earth Bind rose. Body Enhancement rose. Twelve of her fourteen traits stood on the wall of shelves, each one with its hand raised.

Two traits did not. Death Looper did not move. The trait had not been built for vessels. The trait was a clock that ran in the background of her existence, and the trait understood, in whatever way a trait could understand, that a clock above her head wherever she went was not the kind of attention she wanted to attract.

Death Looper held its place. Perfect Assimilation did not move either.

But Perfect Assimilation did something else. It listened.

The trait that had unfolded inside her on the night of the goddess, the trait that held all the other traits, the trait that was, in some deep sense she did not yet have words for, the trait that was her, listened to the call of the core and considered the twelve hands raised on the wall of shelves.

Then, slowly, it lowered all of them.

Ayla felt the lowering. She did not understand it. She had been expected by her grandfather and by Maren and by the chamber itself to choose.

The choice was the second stage. The choice was the moment the witnesses had come for. She had not chosen. The choice had been taken from her.

A small panic flickered at the edge of her chest. She reached for it and steadied it the way Kareem had taught her to steady her stance during the First Gate.

The panic settled. Her breath evened. If Perfect Assimilation had something to say, she would let it say it.

The Apocalypse core inside her finished its reverse rotation. The pull at the wall of shelves resolved. The trait that had answered the call did not present itself by name. It did not announce. It simply began to form.

Above the platform, in the column of violet-black light that had narrowed during the alignment, the column began to widen again.

Not into power. Into shape. The runes on the walls, which had been receding to their original glow, brightened a second time.

The brightening was not absorption. The brightening was attention.

A faint, slow rotation began in the air above the pedestal. The rotation was the same rotation the Apocalypse core had worn since it had appeared above the testing platform yesterday morning.

It was, Ayla understood with a small, calm clarity, the rotation of something that had been waiting to be seen.

The shape thickened. It pulled silver from the runes. It pulled violet from the column. It pulled gold from the air around her, the gold of her own irises, the gold of the goddess that had been folded into her on the night of her birth.

It became.

In the tiered seats, the older men and women in the civilian colors of the high houses leaned forward in their chairs.

The officers in dress uniforms set their hands on the railings. The heirs beside them stopped breathing in the same beat.

In the front row of the second tier, Austin Marsh, who had spent the implantation arranging his posture for maximum visibility, registered the shape of the thing forming above the platform and forgot for the first time in five years to maintain his profile.

His mouth opened.

In the safety zone at the edge of the platform, Roric Vale, Diamond rank, General of the Eastern Front, veteran of forty campaigns, raised his head and looked at the vessel his granddaughter had summoned, and the hand he had let fall to his side returned without his permission to the grip of his sidearm.

Beside him, Maren took one step backward. Kenji, at his anchor point, lifted his eyes and did not lower them. In every tier of the chamber, from the front row to the back, the witnesses rose from their seats.
