The last variable

Error

The queue had been moving since dawn.

Kael Drent stood forty-third in it, counting back from the front out of habit, the way he had always counted things he could not control. The registration center occupied what used to be the Arndale shopping complex, though half the original structure had been swallowed three years ago during the third expansion, its eastern wing now jutting into the grey shimmer of a pocket dimension like a tooth pushed sideways. The city had simply built around the boundary. Manchester adapted. It always had.

He shifted his weight and watched the people ahead of him file through the glass partition one by one. The process was exactly as efficient as the government broadcasts had promised. Palm to crystal, two seconds, classification returned. The registrar at the desk barely looked up between each one. She had done this several hundred times already this morning and would do several hundred more before close.

The tablet hanging from Kael’s neck was a flat grey rectangle, worn smooth at the corners from years of handling. He had owned three versions of it since he was four years old. He typed into it the way other people breathed, without thinking about it, the words appearing on the small speaker face before being read aloud in a voice he had long since chosen to think of as his own.

He did not use it now. There was nothing to say to anyone here.

Two rows ahead, a teenage girl received her class and burst into immediate, ugly tears, covering her face with both hands while her mother grabbed her by the shoulders. Healer class, probably, or one of the support-line designations that still carried stigma despite everything. Kael watched without expression. Three people down from her, a man roughly his father’s age received his classification and threw both arms into the air, laughing so hard it was almost soundless, his whole body shaking. Warrior class, or maybe Assault. Something that matched what he had imagined for himself.

Kael had not imagined anything for himself. He had simply come because the letter requiring attendance had arrived and because not attending carried a fine he could not pay.

The queue moved. He moved with it.

When he reached the partition the registrar was already extending one hand toward the crystal without looking at him, her attention on the form she was completing for the previous person. The crystal sat in its mount on the counter, a fist-sized growth of pale blue mineral that the System used as a receiver. Kael pressed his palm flat against it.

He felt the read begin the way everyone described it, a faint pulling sensation, like the surface tension of water against the skin.

It did not stop after two seconds.

The registrar looked up at three seconds. At five, she sat forward in her chair. At eight, a small frown had settled between her brows. At eleven, the crystal dimmed and the display screen beside it returned a single word in red text.

ERROR.

She tried again. The same eleven seconds. The same word.

She picked up her phone without speaking and made a brief call, her mouth angled slightly away from him. Kael watched her lips anyway. He had been reading lips since he was six, filling in the gaps left by a world that announced itself in frequencies he could not access. She said: *I need a supervisor at station four. Null result. Yes, twice.*

A supervisor arrived, a heavyset man in a registration authority jacket who reviewed the screen, reviewed Kael, and then leaned toward the registrar and spoke in the way people did when they assumed a deaf person was receiving none of it.

*System can’t classify him. No class allocated, no stat distribution, no skill load. Nothing to work with. Happens sometimes with edge cases.* A pause. *Give him the denial form and point him to the exit.*

Kael accepted the form when it was handed to him. He folded it once and put it in his jacket pocket without reading it. He already knew what it said. He had looked up the null classification process two nights ago, lying on the floor of his flat with his tablet balanced on his chest, working through the government portal until the language became clear enough to understand.

Null meant: the System found no basis for classification. Null meant: no class, no stats, no access to the dungeon network in any official capacity. Null meant: try again in six months, pending review.

The supervisor was already walking back to his station.

Kael stepped outside into the flat grey morning. He sat on a concrete barrier at the edge of the pavement and unfolded the letter, the other letter, the one he had carried in his left inside pocket for three years. It was soft along the creases from handling, the ink slightly faded in the places his thumb had worn it most.

Soren’s handwriting had always looked like it was in a hurry.

*Whatever the system tells you about yourself, it is working from incomplete information. So was I. I am sorry. Find me when you are ready.*

Kael read it twice, the way he always did, and then folded it carefully back into its creases and returned it to his pocket.

He looked at the registration building for a long moment. The queue was still moving. People were still stepping up to the crystal and walking away as someone new, or walking away as someone already defined. The door opened and closed. The grey shimmer of the pocket dimension boundary caught the weak morning light along the roofline.

He stood up, crossed the pavement, and got back in line.

It took another twenty minutes to reach the front again. The same registrar looked up when he stepped to the counter. Something moved across her face, not quite recognition and not quite warning.

Kael placed his palm against the crystal for the fourth time as the supervisor straightened at his station and began moving toward them.
