Conservation of Shadows - By Yoon Ha Lee Page 0,47

undone, and all her guns unmade. Shiron will no longer have to be an exile in this timeline, although it is true that she cannot return to the one that birthed her, either.

Shiron snaps the painting taut. The mountain disintegrates, but she lost it lifetimes ago. Silent lightning crackles through the air, unknots Zheu Kerang from his human-shaped shell, tessellates dead-end patterns across the equations that make him who he is. The painting had other uses, as do the other things in this room—she believes in versatility—but this is good enough.

Kerang’s body slumps on the couch. Shiron leaves it there.

For the first time in a long time, she is leaving Blackwheel Station. What she does not carry she can buy on the way. And Blackwheel is loyal because they know, and they know not to offend her; Blackwheel will keep her suite clean and undisturbed, and deliver water, near-freezing in an elegant glass, night after night, waiting.

Kerang was a pawn by his own admission. If he knew what he knew, and lived long enough to convey it to her, then others must know what he knew, or be able to find it out.

Kerang did not understand her at all. Shiron unmazes herself from the station to seek passage to one of the hubworlds, where she can begin her search. If Shiron had wanted to seek revenge on Arighan, she could have taken it years ago.

But she will not be like Arighan. She will not destroy an entire timeline of people, no matter how alien they are to her.

Shiron had hoped that matters wouldn’t come to this. She acknowledges her own naïveté. There is no help for it now. She will have to find and murder each child of Arighan’s line. In this way she can protect Arighan herself, protect the accumulated sum of history, in case someone outwits her after all this time and manages to take the Flower from her.

In a universe where determinism runs backwards—where, no matter what you do, everything ends in the same inevitable Ω—choices still matter, especially if you are the last guardian of an incomparably lethal gun.

Although it has occurred to Shiron that she could have accepted Kerang’s offer, and that she could have sacrificed this timeline in exchange for the one in which neither Arighan nor the guns ever existed, she declines to do so. For there will come a heat-death, and she is beginning to wonder: if a constructed sentience—a computer—can have a soul, what of the universe itself, the greatest computer of all?

In this universe, they reckon her old. Shiron is older than even that. In millions of timelines, she has lived to the pallid end of life. In each of those endings, Arighan’s Flower is there, as integral as an edge is to a blade. While it is true that science never proves anything absolutely, that an inconceivably large but finite number of experiments always pales besides infinity, Shiron feels that millions of timelines suffice as proof.

Without Arighan’s Flower, the universe cannot renew itself and start a new story. Perhaps that is all the reason the universe needs. And Shiron will be there when the heat-death arrives, as many times as necessary.

So Shiron sets off. It is not the first time she has killed, and it is unlikely to be the last. But she is not, after all this time, incapable of grieving.

ISEUL’S LEXICON

kandagghamel, noun: One of two names the Genial Ones used for their own language. The other, menjitthemel, was rarely written. Derived from kandak, the dawn flower of their mythology and a common heraldric device; agha, or “law”; and mel, “word” or “speech.” Note that mel is one of a small class of lexical elements that consistently violates vowel harmony in compounds. The Genial Ones ascribe considerable metaphysical importance to this irregularity.

She went by the name Jienem these days, a proper, demure Yegedin name that meant something between “young bud” and “undespoiled.” It was not her real name. She had been born Iseul of Chindalla, a peninsula whose southern half was now occupied by the Yegedin, and although she was only the bastard daughter of a nobleman and an entertainer, she never forgot the name her mother had given her.

The Empire of Yeged had occupied South Chindalla for the past thirteen years, and renamed it Territory 4. Yeged and free Chindalla had a truce, but no one believed it would last for long, and in the meantime Chindalla had no compunctions about sending agents into South Chindalla. People
