Then Chasm City was no longer beneath us, but the toothed edge of the crater wall; the behemoth slicing expertly through a notch in the rim which looked only just wide enough to accommodate it.
Ahead I could see a huddle of armoured structures near one edge of a butterscotch-coloured lake. The behemoth lowered itself towards the lake, the scream of its thrusters audible now as it fought to hold itself at this altitude against its natural tendency to float upwards.
‘Disembarkation time,’ Quirrenbach said. He got up from his seat, indicating a general flow of people across the lobby.
‘Where are they all going?’
‘To the drop capsules.’
I followed him across the lobby, where a dozen sets of spiral stairs led to the disembarkation level, a whole deck below. People were waiting by glass airlocks to board teardrop-shaped capsules, dozens of them which were slowly being pushed forward along guideways. At the front, the capsules slid down a short ramp which was jutting from the behemoth’s belly, before falling the rest of the distance — two or three hundred metres — and splashing into the lake.
‘You mean this thing doesn’t actually land?’
‘Good heavens, no.’ Quirrenbach smiled at me. ‘They wouldn’t risk landing. Not these days.’
Our drop capsule slid from the behemoth’s belly. There were four of us in it: Quirrenbach, myself and two other passengers. The other two were engaged in an animated conversation about a local celebrity called Voronoff, but they spoke Norte with such a strong local accent that I could only follow about one word in three. They were completely unfazed by the experience of dropping from the behemoth; even when we plunged deep into the lake and appeared in some danger of not bobbing to the surface. But then we did, and because the drop capsule’s skin was glassy, I could see other capsules bobbing around us.
Two giant machines strode across the lake to receive us. They were tripods, rising high above us on skeletal, pistonned mechanical legs. With cranelike appendages they began to collect the floating capsules and deposit each in a collecting net stowed beneath the body of each tripod. I could see a driver perched at the top of each machine, tiny inside a pressurised cabin, working levers furiously.
The machines walked to the lake’s edge and emptied their catches onto a moving belt which fed into one of the buildings I’d seen from the behemoth.
Inside, we were passed into a pressurised reception chamber where the pods were removed from the belt and opened by bored-looking workers. Empty pods were shuttling around to an embarkation area similar to the one aboard the behemoth, where passengers waited with luggage. I presumed they’d be carried out to the middle of the lake by the tripods, which would then loft each pod high enough up for the behemoth to grab it.
Quirrenbach and I left our pod and followed the flow of passengers from the reception chamber through a warren of cold, dim tunnels. The air tasted stale, as if each breath had already been through a few lungs before it reached my own. But it was breathable, and the gravity not noticeably heavier than in the Rust Belt habitat.
‘I don’t know quite what I was expecting,’ I said. ‘But this wasn’t it. No welcoming signs; no visible security; nothing. It makes me wonder what the immigration and customs section will be like.’
‘You don’t have to wonder,’ Quirrenbach said. ‘You’ve just left it.’
I thought about the diamond gun I’d given Amelia, secure in the knowledge that there was no way I would be able to take it with me to Chasm City.
‘That was it?’
‘Think about it. You’d find it exceedingly difficult to bring anything into Chasm City which wasn’t already there. There’s no point checking for weapons — they’ve got enough of them already, so what difference would one more make? They’d be far more likely to confiscate whatever you had and offer you part-exchange on an upgrade. And there’s no point screening for diseases. Too complicated, and you’re far more likely to catch something than bring something into the city. A few nice foreign germs might actually do us some good.’
‘Us?’
‘Them. Slip of the tongue.’
We passed into a well-lit area with wide windows overlooking the lake. The behemoth was being loaded with capsules, the dorsal surface of the manta-like machine still bright with the thrusters it had to burn to hold this position. Each pod was sterilised by being passed through a ring of purple flame before being accepted into the behemoth’s belly. Maybe the city didn’t care what came into it, but the outside universe certainly seemed to care what left it.
‘I suppose you have some idea how we get to the city from here?’
‘There’s really only one way, I gather, and that’s the Chasm City Zephyr.’
Quirrenbach and I brushed past a palanquin, moving slowly down the next connecting tunnel. The upright box was patterned in bas-relief black, showing scenes from the city’s vainglorious past. I risked a glance back as we overtook the slow-moving machine and my gaze met the fearful eyes of the hermetic sitting within: face pale behind thick green glass.
There were walking servitors carrying luggage, but there was something primitive about them. They were not sleek intelligence machines, but clunking, error-prone robots with about as much sentience as a dog. There were no genuinely clever machines left now, outside of the orbital enclaves where such things were still possible. But even the crude servitors that remained were obviously valued: signs of residual wealth.
And then there were the wealthy themselves, those travelling without the sanctuary of palanquins. I presumed none of these people had implants of any great complexity; certainly nothing that might be susceptible to plague spore. They moved nervously, in hurried packs, surrounding themselves with servitors.
Ahead the tunnel widened into an underground cavern, dimly lit by hundreds of flickering lamps burning in sconces. There was a steady warm breeze blowing through it, carrying a stench of machine oil.
And something enormous and bestial waited in the cavern.
It rode four sets of double rails arranged around it at intervals of ninety degrees: one set below the machine, one above and one on either side. The rails themselves were supported by a framework of skeletal braces, though at either end of the cavern they vanished into circular tunnels where they were anchored to the walls themselves. I couldn’t help but think of the trains in the Santiago which had featured in one of Sky’s dreams, braced within a similar set of rails — even though those rails had only been guidance ways for induction fields.
This wasn’t like that.
The train itself was constructed with a four-way symmetry. At the centre was a cylindrical core tipped with a bullet-shaped prow and a single Cyclopean headlight. Jutting from this core were four separate double rows of enormous iron wheels, each of which contained twelve axles and was locked onto one of the pairs of rail lines. Three pairs of huge cylinders were interspersed along each set of twelve main wheels, each connected to four sets of wheels by a bewildering arrangement of gleaming pistons and thigh-thick greased articulated cranks. A mass of pipe-runs snaked all around the machine; whatever symmetry or elegance of design it might have had was ruined by what appeared to be randomly placed exhaust outlets, all of which were belching steam up towards the cavern’s ceiling. The machine hissed like a dragon whose patience was wearing fatally thin. It seemed worryingly alive.
