On two or three occasions, though, he saw more. The shells of cloud that enveloped the center of Virga sometimes parted, revealing the sun of suns, Candesce. Daylight would suddenly flash out to fill the entire volume of winter. Each time, Hayden had stood on the air, amazed at the brilliance of it—at the sheer size of an ancient, untended fusion engine that put all other suns in Virga to shame. Dozens of civilizations depended on that single central light, he'd heard. It was the greatest source of heat in the world; it drove the circulation cells in which Aerie and the other nations migrated slowly inward and outward.

The core components of his parents' sun had come from Candesce; the sun of suns was the wellspring for all of Virga's lesser lights.

"It was a year before Katcheran had enough fuel for us to fly back, and then he followed the beacons he knew, which brought us in a hundred miles away from Gavin Town. Of course, the town was a legend by then, but nobody knew much about it. Any pieces that were left after Slipstream attacked had been dismantled or drifted away. I didn't have anybody to go to… any way to get in touch with the Resistance, unless I came to Rush, and I didn't have any money to travel. I got a job in a kitchen in Port Freeley and saved until I could get passage here.

"But you know what I found out when I finally got back to Aerie? Nobody knew about our sun! Nobody knew. We'd built it in secret, and Slipstream attacked in secret, and nobody told the people what had happened. If they'd known… something might have been done." He shook his head. "Maybe the Resistance couldn't have kept Slipstream from finding the sun and destroying it. I don't know. But you could have told—you had the responsibility to tell the people of Aerie what had happened.

"How could I get involved with you again after that?"

Miles looked troubled, but Billy just raised an eyebrow. "So why are you working for the Fanning's? It took you a lot of effort to do it—you even forged your Slipstream citizenship yourself, by the looks of it."

Hayden stared at him. "Well, why do you think I came here? I came to kill Admiral Fanning."

There was a brief silence while the other three looked at one another. Then Billy cracked a slight smile. "Why in Virga would you want to do that?"

"Because he's the one." Hayden didn't care that the man in black was a killer. The indignity of having his motives suspected was just too much. "I saw the name on the side of the flagship that attacked us. The Arrogance. It was Fanning's ship when he was still commodore. He blew up our sun! He killed my mother! I care about that. Don't you care? What have you been doing here, all these years? What kind of a resistance is this? You're supposed to be an assassin, why haven't you killed him?" He stepped over to Shambles's table and tossed some of the papers in the air. "What, are you gonna plan them all to death? Is that the idea? Well, while you've been squatting on your asses in your little box, I've been doing something with my time. I was ten feet away from him today; tomorrow I'll be right there, and then he'll be dead."

He glared at them. "That's why I came here. That's what I'm doing. So what are you doing?"

Shambles adjusted his glasses and patted down the papers. "Well, Hayden my lad, we're trying to save our country. That would seem like a very different goal from yours, now wouldn't it?"

"Oh, please," said Hayden, crossing his arms. "What's to save? Slipstream annexed Aerie ages ago. I don't even remember how it was before that happened. It's ancient history."

"What you say is very true," said Shambles with a thoughtful nod. "However, it is also true that, since Slipstream is a migratory nation, it will someday migrate its way out of Aerie. Our concern is with what happens when that occurs."

Hayden looked at him blankly.

"Hmm." Shambles turned in his chair, crossing his legs. "It is a fact of youth that it has no concept of the future. Yet that is what we are here to discuss. The future of Aerie—and your future."

Hayden snorted.

"Tell me," said Shambles, "what is it, fundamentally, that keeps a nation together?"

Hayden decided to take the bait. "A sun."

Shambles shook his head. "No. It's formation flying. That is what keeps a nation together. If all your towns and farms and water balls are sailing off in different directions, it hardly matters if you've got a sun of your own, does it? What's essential is that you keep everybody flying on the same heading, maintaining the same altitude and position above the Sun of Suns. Aerie is still doing that—for now. The danger is that the presence of the Slipstream sun in our skies will cause parts of the nation to drift away, leave the formation, and join other countries. Hayden, that is a threat far greater than any police actions or propaganda by Slipstream could be."

"For ten years now we've been keeping Aerie in formation," said Miles. "That's what the Resistance does. What possible good would revenge do us? If you kill Fanning, he'll just be replaced."

"Yes," said Hayden, "but he'll also be dead."

Miles sighed. "I brought you here tonight because I hoped we could bring you back into the net. With your position in the Fanning household, you could be invaluable to us—especially now that Slipstream's finally moved close enough to our neighbors that it's been perceived as a threat. Mavery is moving against Slipstream. Slipstream will move into Mavery territory in a year or two and at that point they'll find themselves fighting a two-front war, against Mavery and us. Our job is to prepare for that, and to make sure that when the time comes, we either win or convince them to commit all their forces to Mavery, and leave us behind. If we had a spy in the very heart of the Admiralty…" His expression was greedy.

"Aerie is gone," Hayden said. "When Slipstream leaves they'll take their sun with them. Without a sun, Aerie will freeze in the dark. The people will leave. I've lived in winter. I know what it's like."

"We're working on that," said Shambles. "With the right components we could—"

Hayden shook his head. "I'm only here to do one thing. And after that… I don't care."

"But, Hayden my boy," purred Billy as he put an arm around Hayden's shoulder, "the problem is, we care. It's a worry, you know—the vision of you shooting Fanning and then being caught and tortured. You might talk about us, you see."

"Oh! No, I—"

"Now it would be supremely gauche of me to threaten your life at this point," Billy went on. "After all, as you say, you have your own path to take. That's fine. But if you're not going to join us, then we have one simple request."

"What's that?"

"If you're going to kill Fanning up close and personal like, say in the middle of the Admiralty itself… Just make sure you kill yourself too, hmm? As a favor to us, you see. So we don't have to."

Hayden bolted to the trapdoor and flung it up. "You know where to find us if you change your mind," Shambles called cheerfully.

"You won't hear from me," snapped Hayden as he lowered himself down to the invisible ladder. Slamming the trapdoor he began clumsily backing his way down to the city, fuming and muttering as he went.

He was just above the rooftops when a lurid orange flash lit up the sky. A distant grumble like thunder reached his ears. Hayden paused, clinging to the swaying planks, and listened.

The tearing sound of a jet could be heard fading in the distance. Then another one, growing closer. Funny; he knew all about bikes, but he couldn't identify the type from this one's sound.

Then something flashed by outside the iron stanchions. He poked his head out between the girders in time to see something bright shoot straight into the lit window of a mansion near the far end of the cylinder. To his amazement, the outer wall of the house seemed to dissolve in flame and the whole roof lifted off.
