Annah, leading the way, peeked through the wall's ragged hole. She quickly pulled her head back again.

"What do you see?" Impervia whispered.

"Bodies." Annah took a breath to settle herself. "I think they were Keepers; they're wearing brown robes like monks. The Keepers had set up a reception party outside the elevators-plenty of guns, fancy ones, not ordinary firearms-and I suppose they intended to shoot as soon as the elevator doors opened. But the doors didn't open; the wall blew out on top of them like an avalanche. The Keepers didn't have a chance."

"Stupid of them," Impervia said. "They should have positioned themselves farther back. Given themselves plenty of safety range."

Annah shook her head. "They didn't have enough room. When the OldTechs built this place, they didn't think to put in a proper kill-zone."

Impervia tsked her tongue at such lack of foresight. I decided it was pointless to mention this plant had been a commercial installation, not a military one; Impervia wouldn't have understood the distinction.

Instead, I continued down the ladder until I could see the carnage for myself. The room in front of me was lit with electric lights, very bright after the darkness of the elevator shaft. The place looked like a formal reception area, a spot where visiting dignitaries might gather before a tour of the generating machinery: high-ceilinged, with an ample supply of plush chairs and sofas. At one time, the furniture must have been spaced around the room… but now it was all drawn up in a barricade near the far wall. The Keepers had hidden behind that line, waiting to open fire. Unfortunately for them, their defenses had been no match for exploding rubble-heavy chunks of masonry had blasted out of the wall, smashing through chairs and couches, crushing the people behind. Male and female Keepers lay bleeding beside the barrier, most with fragments of concrete piercing their skulls.

"Jode must have known they'd be waiting here," the Caryatid said.

"Either that," I said, "or Sebastian just looked through the wall and saw them." I thought about nanites filling the air-ready to transmit remote images into the boy's brain whenever he requested. "If Jode asked, 'What's ahead of us?' Sebastian could easily find out."

Annah frowned. "If Sebastian knew people were out here, would he really cause an explosion to kill them all?"

"Why not?" Impervia asked. "Jode has convinced the boy this building is headquarters for the Ring of Knives. Filled with vicious criminals, and commanded by Rosalind's evil mother who wants to interfere with true love. Then, what does Sebastian see when he gets here? People with guns, ready to shoot first and ask questions later."

"Don't forget," I added, "Myoko constantly warned Sebastian about groups like the Ring. She believed all such organizations enslaved psychics; she'd have told the boy he mustn't pull his punches if he ever fought them. Be ruthless, show no mercy-you know how Myoko talked. So even without Jode urging him on, Sebastian would be inclined to rip through anyone who stood in his way."

"He wouldn't listen to Pelinor," Impervia pointed out. "And he won't listen to us the next time we meet him. He thinks we're doppelgängers working for Rosalind's mother. Bags of skin filled with pus."

The Caryatid gave a soft sound that might have been a growl. "We'll show him it's Jode who fits that description. Let's get moving."

Annah went first, still on the lookout for traps. She stepped down to the roof of an elevator car and walked to the hole in the wall. Since the hole was more than two meters above the next room's floor, Annah seated herself on the edge of the broken concrete, then turned and lowered herself as far as she could, hanging on to the lip of the hole with her hands. She still had to drop the last half meter: landing without a sound, her black cloak billowing.

That's when the Keeper stirred and lifted his gun.

It was a young man, plump and bald, with blood smearing his face from where his left eye had been pulped by hurtling debris. He must have been knocked out by the initial blast, then left for dead by Jode and Sebastian. When he woke again, his first thought was to fire on the closest target: Annah. Maybe he was so dedicated to the Holy Lightning, he wanted to spend his last breath destroying what he believed was an intruder; maybe he just wanted to make someone pay for his ruined eye; maybe he was so dazed, he didn't know what he was doing. But he hadn't lost his weapon when the wall blew out on top of him. All he had to do was raise the muzzle.

I shouted to Annah, "Down, down, down!" The Keeper fired before I howled the second, "Down!" but I kept yelling, unable to stop myself.

Annah began to drop flat to the floor… then all hell broke loose.

The Keeper's weapon was an Element gun-a four-barreled monster of overkill invented by Spark Royal. The guns were rare, but my grandmother had received one as a gift the day she was anointed as governor. She'd let me examine it many years later: a big chunky rifle with four barrels arranged in a diamond, one for each of the classical Greek elements.

Earth: ordinary lead slugs, shot at high-velocity.

Fire: a gout of burning gas like a mini-flamethrower.

Air: a focused hypersonic barrage, causing no serious damage but able to knock out a charging rhino for hours.

Water: a stream of acid, corrosive enough to eat through steel.

Element guns were versatile weapons that could harmlessly subdue a single target or incinerate a mob. The guns had their limitations: they were brutally heavy, they couldn't be reloaded except by the Sparks, and you had only a few shots on any one setting. Still, if you liked a lot of options for wanton destruction, an Element gun fit the bill. You could fire each barrel separately, or mix and match to tailor your attack to your target.

The Keeper fired all four barrels at Annah. Simultaneously. The resulting blast was a pandemonium of light and sound, a blare of pure chaos that lasted only a fraction of a second; but in my mind's eye, it seemed to break into distinct pieces that each lasted forever.

I imagined the bullets reaching her first: an eruption of lead traveling faster than sound. Since she'd been diving forward, facing the shooter, the slugs would hit her in the head, the shoulders, and chest.

The hypersonics would arrive next. It was the same kind of attack Opal had talked about-the pistol she'd been carrying in the tobacco field. It hadn't affected the Lucifer, but I prayed it would work on Annah: frazzling her nervous system, hammering her into merciful unconsciousness so she couldn't feel the horrors to come.

Then fire. A flammable gas, something that blazed bright orange, pouring in a burning jet. Igniting her clothes, her hair, her beautiful skin.

Finally, the acid, its spray traveling slower than bullets, sound, and fire. Acid splashing onto the flames. I couldn't tell whether the acid would burn off harmlessly, or if the heat would make it work that much faster: disintegrating what was left of Annah's corpse.

Annah's corpse.

Then it was all over. The Keeper toppled forward across the furniture barricade, smoke pouring off his body. The gun clattered from his hands. Impervia leapt to the floor as if there was something she could do for Annah, but I remained frozen where I was.

The Caryatid slumped beside me. Her face was damp; not tears, but perspiration. "Ugh," she said. "Let's not do that again."

I stared at her, shocked at her lack of feeling for Annah. Before I could speak, something fluttered down in the room: Impervia had just kicked Annah's cloak and a few more pieces of clothing halfway across the floor. "Get down here, Phil!" Impervia snapped. "We need your first aid kit."

We?
