"That last sounds most likely," Annah said. "It doesn't leave as much to chance; he could have been hiding the whole contraption right inside his body." She looked up at the bright blue planet in the sky. "By the way, I don't think that's the real Earth… and this isn't the real moon. There's no air on the moon, is there?"
"True. And there shouldn't be this much gravity either." I took a tentative jump. It felt like jumping on Earth — nowhere near the big bounce I'd have made under weak lunar gravity. "Both Jode and Dreamsinger talked as if those fancy rods sent you to an alternate dimension. I guess it amused the Sparks to make this prison look like the face of the moon: emphasizing the sense of banishment. But you're right, this isn't the real…"
A sizzling noise interrupted me. Annah and I whirled toward the sound.
Three paces away, Sebastian lay in the dust, still hugging himself into a fetal ball. One of the Lucifer blobs had pushed up against him during its mindless wanderings. Now, plumes of smoke billowed between it and the boy, as Sebastian's nanite protectors fought off the alien cellules; but the blob was too stupid to realize it had caught fire. It turned to one side, like a worm that has bumped against a wall and starts to inch along the wall itself — the worst thing the blob could do under the circumstances. It continued sliding along the length of Sebastian's body, burning all the way as the nanites continued to attack… but even before the blob reached Sebastian's toes and wobbled away smoldering, the nanite-generated flames had begun to dwindle. They just weren't as strong as when the blob had first stubbed up against the boy.
I wondered: was that because the nanites realized the blob wasn't bothered by fire? Or could there be another explanation?
Carefully, I stepped in and eased the bottom of my boot toward Sebastian's knee. I felt some resistance, like pushing through sand… but after a moment it yielded and my foot touched the boy's pant-leg.
"What are you doing?" Annah asked.
"Nanites," I said. She looked at me blankly; she hadn't been there when Myoko explained psionics to me. "It's too complicated to go into details," I told her, "but just as the Lucifer consists of little independent cellules, Sebastian's powers come from the same sort of thing: microscopic entities, sort of like bacteria. They're ubiquitous on Earth… but not here. The only nanites in this place are the ones we brought with us — in our bodies, in our clothes, and in Sebastian's protective shell."
Annah wrinkled her forehead. "So these nanites are cut off from the whole, just like the cellules?"
I nodded. "They're used to operating on Earth, where they're always surrounded by trillions of their kind. So think about them burning that blob just now — the nanites probably did it by incinerating themselves. On Earth that would be no problem, since there'd always be plenty of replacements for the ones that went up in flames; but here, where there are no replacements… every nanite that dies protecting Sebastian means the shell around the boy gets weaker."
"And I'll bet," said Annah, "the nanites left over aren't as smart. These things must be another collective intelligence, right? Just like the Lucifers. And when nanites burn up, it's like losing brain cells. The rest get more stupid."
She had a point. Under normal circumstances, nanites could draw on each other for brainpower — all the nanites in the air, the soil, everywhere. But here on this barren moon, with no fellow nano except themselves… it really was like the Lucifer cellules: once part of a huge brain, now fending for themselves. My ability to touch Sebastian proved his nanite protectors were no longer functioning normally.
I dabbed my foot once more against Sebastian's leg. This time there was no resistance at all; the protective shell had dissipated, the nanites too feeble-minded to stick to their programming. I crouched and hesitantly moved my gloved hand to the boy's arm. No nanites tried to stop me… so I gave him a light squeeze. "Sebastian. It's Dr. Dhubhai. Are you all right?"
He whined softly and tried to crunch himself into a tighter ball. Annah knelt beside me. "Give him time, Phil. There's no hurry, is there?"
I thought about the evil Lucifer, unrestrained now that the laser cage in Niagara had lost its power. Surely it would flee from the generating station as fast as possible, splitting itself into human-sized doppelgangers and blending into the local populace. If the creature didn't run, more Sparks would eventually show up, at which point…
At which point, the Lucifer could have disguised itself as a group of Keepers, wearing robes pulled off the corpses of real Keepers. The aliens might take the Sparks by surprise — might even kill a Lord or two by leading them into a trap. And if the trick didn't work, so what? Satan just lost a few million cellules. The overmind wouldn't care; it lost cellules all the time. Satan would gladly sacrifice a bit of itself for the chance of killing even one Spark.
The first Spark to die would be Dreamsinger. Even now, she lay unconscious before Satan's malice. The great black heap could simply press down on her until it had exhausted whatever batteries powered her force field; or maybe it could form an airtight dome over her, preventing the inflow of oxygen until Dreamsinger smothered. For that matter, maybe the same biological mechanisms that made lightbulbs and toasters could also manufacture neurotoxins: poisonous gases that the unconscious Sorcery-Lord would helplessly inhale.
All kinds of possibilities.
"I think we might be in a hurry after all," I told Annah. "We should wake Sebastian and get back to Niagara fast. Sebastian can use his powers to cage up the Lucifer… or destroy it outright, now that it's turned bad." I paused as another thought struck me. "Even if the Lucifer isn't raising havoc, we have to remove that dam across the river. By now, it's surely causing a flood — in the middle of a big city. People could die."
She met my eyes, then nodded. "Any ideas on how to break through the boy's trauma?"
"No. I tried and got nowhere."
Annah gave me a reproachful look. "You weren't working under the best conditions… but if you don't want to talk to him again, I'll see what I can do."
"He's all yours. He might respond better to a female voice."
She held my gaze a moment longer… then turned to Sebastian and called his name softly. I stood and walked away — as if my very presence could hamper Annah's progress. Ridiculous to feel self-pity at such a time; but as I stared at the Earth in the big black sky, the only thing on my mind was the leaden weight of failure.
The good Lucifer had believed that some force — the League of Peoples or someone else — recruited me to preserve the angel's soul. I'd been brought to Niagara Falls by the haunting and the prophecy because I supposedly had some strength, some skill, some gift which would let me save the day. Part of me had wanted to believe the myth: that I was special, a hero with hidden depths who could turn defeat into victory.
But I hadn't got through to Sebastian. The laser cage had flickered out. The good Lucifer was gone forever, its consciousness swallowed by evil. And if Sebastian eventually came to his senses, the credit would be Annah's — Annah, who'd rescued herself quite handily without any help from me.
I hadn't rescued a single person. Hadn't died in noble sacrifice. Hadn't used my scientific knowledge to conquer the foe. Hadn't used anything except my friends and my money-purse… as always.
A surge of disgust swept over me. I reached into my pocket, pulled out the purse, and cocked back my arm — intending to hurl the damned thing away from me, a symbol of my perennial uselessness. But before I completed the throw, I stopped. Something wasn't right. The purse: it was heavier than it should have been. Much heavier. And bulging tautly, like a rubbery black soccer ball inflated to maximum pressure.
