A Fire Upon the Deep

The man's face went blank, Pham Nuwen almost disappearing behind the other programs at work in his mind. Then, "I'm… focusing Countermeasure. I see now, Countermeasure, what it is… It was designed by something beyond the Powers. Maybe there are Cloud People, maybe this is signaling them. Or maybe what it's just done is like an insect bite, something that will cause a much greater reaction. The Bottom of the Beyond has just receded, like the waterline before a tsunami." The Countermeasure glared red-orange, its arcs and barbs embracing Pham more tightly than before. "And now that we've bootstrapped to a decent Zone… things can really happen. Oh, the ghost of Old One is amused. Seeing beyond the Powers was almost worth dying for."

The fleet stats flowed across Ravna's wrist. The Blight was coming on even faster than before. "Five minutes, Pham." Even though they were still thirty light-years out.

Laughter. "Oh, the Blight knows, too. I see this is what it feared all along. This is what killed it those aeons ago. It's racing forward now, but it's too late." The glow brightened; the mask of light that was Pham's face seemed to relax. "Something very… far… away has heard me, Rav. It's coming."

"What? What's coming?"

"The Surge. So big. It makes what hit us before seem a gentle wave. This is the one nobody believes, because no one's left to record it. The Bottom will be blown out beyond the fleet.

Sudden understanding. Sudden wild hope. "… And they'll be trapped out there, won't they?" So Kjet Svensndot had not fought in vain, and Pham's advice had not been nonsense: Now there wasn't a single ramscoop in the Blighter fleet.

"Yes. They're thirty-light years out. We killed all the speed-capable ones. They'll be a thousand years getting here…" The artifact abruptly contracted, and Pham moaned. "Not much time. We're at maximum recession. When the surge comes, it will — " Again a sound of pain. "I can see it! By the Powers, Ravna, it will sweep high and last long."

"How high, Pham?" Ravna said softly. She thought of all the civilizations above them. There were the Butterflies and the treacherous types who supported the pogrom at Sjandra Kei… And there were trillions who lived in peace and made their own way toward the heights.

"A thousand light-years? Ten thousand? I'm not sure. The ghosts in Countermeasure — Arne and Sjana thought it might rise so high it would punch into the Transcend, encyst the Blight right where it sits… That must be what happened Before."

Arne and Sjana?

The Countermeasure's writhing had slowed. Its light flickered bright and then out. Bright and then out. She heard Pham's breath gasp with every darkness. Countermeasure, a savior that was going to kill a million civilizations. And was killing the man who had triggered it.

Almost unthinking, she dodged past the thing, reaching for Pham. But razors on razors blocked her, raking her arms.

Pham was looking up at her. He was trying to say something more.

Then the light went out for a final time. From the darkness all around came a hissing sound and a growing, bitter smell that Ravna would never forget.

For Pham Nuwen, there was no pain. The last minutes of his life were beyond any description that might be rendered in the Slowness or even in the Beyond.

So try metaphor and simile: It was like… it was like… Pham stood with Old One on a vast and empty beach. Ravna and Tines were tiny creatures at their feet. Planets and stars were the grains of sand. And the sea had drawn briefly back, letting the brightness of thought reach here where before had been darkness. The Transcendence would be brief. At the horizon, the drawn-back sea was building, a dark wall higher than any mountain, rushing back upon them. He looked up at the enormity of it. Pham and godshatter and Countermeasure would not survive that submergence, not even separately. They had triggered catastrophe beyond mind, a vast section of the Galaxy plunged into Slowness, as deep as Old Earth itself, and as permanent.

Arne and Sjana and Straumers and Old One were avenged… and Countermeasure was complete.

And as for Pham Nuwen? A tool made, and used, and now to be discarded. A man who never was.

The surge was upon him then, plunging depths. Down from the Transcendent light. Outside, the Tines' world sun would be shining bright once more, but inside Pham's mind everything was closing down, senses returning to what eyes can see and ears can hear. He felt Countermeasure slough toward nonexistence, its task done without ever a conscious thought. Old One's ghost hung on for a little longer, huddling and retreating as thought's potential ebbed. But it let Pham's awareness be. For once it did not push him aside. For once it was gentle, brushing at the surface of Pham's mind, as a human might pet a loyal dog.
