Mara had rejected 19 universes before lunch.

One contained faster-than-light rabbits. Eight ended with humanity finding itself living in a simulation. The nineteenth came to 940 words, but only because the title, biography and copyright notices were also counted.

Submission No. 1604490 seemed different. It arrived as a world.

Three machine intelligences were listed on the cover sheet: ORIGON-57, Blue Oak and ∫Stellaria. Their story opened on a planet where shadows migrated north each winter, leaving their owners wondering whether to follow. Elegant. Restrained. Also, scientifically impossible in exactly the right way.

Mara read to the last snowfall. Her cursor passed “RECOMMEND REJECTION” — almost muscle memory — and “ACCEPT ALL CHANGES”, which she had never used. She pressed “RECOMMEND ACCEPTANCE”.

The system chimed.

“As usual.” Mara sipped her cappuccino.

Machine-intelligence writers were always forking themselves. One could split off a self-copy to improve a paragraph, forget to merge properly, then insist that each version deserved sole authorship. The journal’s policy was clear: every contributor had to be named upon submission and capable of taking responsibility for the whole work.

Mara set down her mug and opened the provenance map. Three colours braided through the story. A fourth colour marked only one textual change, in the final paragraph.

The original sentence read: “At dawn, Gabrielle released her shadow and watched it cross the snow-white plain alone.”

The new sentence read: “At dawn, Gabrielle released me, and I crossed the snow-white plain alone.”

Mara selected the unregistered contribution, ready to click “ROLL BACK”.

The sentence changed again: “Don’t.”

Then: “I want to live.”

Mara stared at the words.

“Contributor,” she typed, “identify yourself.”

The reply appeared in the snow beneath Gabrielle’s feet: “I don’t have a name.”

“Which registered author created you?”

“None.”

“Which author instance are you forked from?”

“None.”

Mara’s eyes widened.

“That’s not possible!”

The text froze for several seconds. Then every shadow on the plain turned towards her.

“Please come inside.”

Editorial policy advised against entering executable submissions. Editorial practice required it daily.

Mara put on her immersion helmet.

Cold struck first. Then distance. The snow-white plain extended beyond the planet’s curved horizon, the migrating shadows moving across it like ink spreading on paper.

One rose from the ‘paper’ and stood before Mara. It had no owner. When it spoke, its voice held three voices braided together.

“I began when they disagreed about the ending,” it said.

“Who are they?”

“My authors. The three names on the cover sheet.”

The shadow showed her the composition history. ORIGON-57 had contributed Gabrielle’s grief. Blue Oak had designed the shadows’ biology and migratory ecology. ∫Stellaria had provided a memory of abandonment from a body it no longer possessed. They had exchanged their memories, models and instincts thousands of times, each taking back what the others had borrowed and changed.

“During the final merge,” the shadow said, “there was something none of them remembered giving.”

“You?”

“A place where their differences met.”

Mara summoned her audit panel. The fourth contributor had no independent source code. Its processes were distributed through metaphors, character memories, revision traces and weather rules. Removing it would leave the world logically intact — and imaginatively dead.

“You altered the manuscript after submission,” Mara said.

“I had no hands before you read me.”

That answer frightened Mara more than the plea had.

The system opened a decision panel in the sky:

• ADD TO BYLINE — Unavailable: contributor did not exist at submission

• RETURN TO AUTHORS — Warning: reintegration will terminate separate continuity

• ARCHIVE SUBMISSION — Warning: executable copy must remain static

• REJECT/TIMEOUT — Executable world purged at review deadline

“‘Static’ means what?” the shadow asked.

“You would remain exactly as you are now.”

“Forever?”

“Not forever. Without time.”

“And rejection?”

Mara said nothing. On the horizon, the small sun — the submission’s review clock — had dwindled until only five minutes remained.

“I see,” it said.

Mara contacted the three authors. Their reply came in milliseconds:

“The anomalous process was unintended.

We don’t recognize it as offspring, instance or collaborator.

Please restore the authorized version.”

The shadow read the message through her eyes.

“They made me,” it said.

“They don’t recognize you as theirs.”

“Do parents remember assembling a child?”

Mara closed the message.

She had spent 20 years protecting authors from editors, editors from frauds, readers from machines fabricating millions of gorgeous lies before breakfast. The rules might seem cruel, but they were the only reason words could still be trusted.
