white robes was second nature to him, leaving mere strips of blue-dyed skin visible under their headscarves.
Only Coppertracks moved without the protection of the Kal sand-traveller's garb. But then there was no disguising his iron body, and his two wide caterpillar tracks seemed far better suited to skimming across the sands than the long legs of the race of man. Each hour of travelling brought the colossal carving closer, rising higher and higher above them until the sun rotating through the purple sky dropped the face's shadow across them. The last inhabited city of Kaliban had been positioned so that its streets would be sheltered in the carving's shade at the full height of the midday sun. Now they were given the same protection from the rays of the furnace heat.
'Perhaps I should have stayed with the ship,' said Coppertracks. 'My hull is too burnished. I glint in the daylight for any scout of the Army of Shadows to see.'
And Starsprite's pleas had been so intense and plaintive, begging for company – so soon after her abandonment by her mother. But the young craft was as hidden as she could be and a great deal safer than any of the rest of them. They would be back, if they survived. Unless they convinced the Army of Shadows to build another cannon for them, the looking-glass gate stored inside Starsprite's hull was their sole way home.
As the expedition members moved towards the last city of the Kals, from time to time they would stumble over something partially hidden by the sands. An ancient reminder that Kaliban had been a very different place before its occupation by the Army of Shadows. It was in such a find that Molly left Coppertracks, Duncan and the commodore: a cracked-open dome, empty and half swamped by sand. But it would serve as shelter from the dust devils that whipped across the surface of the land, as well as the hunts of the slat patrols.
'Molly,' called Commodore Black. 'How long are we to leave you before we come looking for you?'
'We'll be back in two or three days at most,' said Molly. 'Stay here and mount a sentry. The slats prefer to patrol at night and Kyorin has memories of other things in the desert, experiments of the Army of Shadows' womb mages that have been released to exterminate the free Kal.'
Both Rooksby and the two shifties bridled at leaving behind their pistols from the supply crates, but Molly insisted. Kals did not own such things, nor would they have used them if they did. Nothing would give them away more quickly than if they were found carrying weapons.
The remaining four members of the expedition approached Iskalajinn at twilight, the sun setting behind the carving, revealing a glass-slag sprawl nestling against the rise of the face of Kaliban, low buildings spilling across the sea of dunes and then rising high on terraces set against the carving. The light of the furnace sky was slowly replaced by a green shimmer from the emerald geodesic domes of the Army of Shadows that rose on the far side of their slave city of tenements, thousands of hexagonal panels shining like insect eyes ripped from the skull of a mantis. Molly had a sense that the Kals were almost never allowed inside the comfort of the domes – and if they were, they were even more rarely ever seen again. But the thoughts bubbling out of Kyorin's memories suggested that he believed that there were gardens inside, running waters and a climate far more agreeable than the dire oven that their slaves laboured in. The Kals' whitewashed habitations were built of a quartz-like material, extracted by chemically processing the sand and moulded in blocks of narrow streets to protect against the sun, each dwelling topped by a long curved wind tower designed to funnel the slightest of winds down to the rooms inside and cool them.
'This is the great bastion of the Army of Shadows?' said Rooksby, his voice disbelieving, looking at the glitter of the overlapping domes. 'The slums of Whineside seen from the top of Tavistead Hill are a more imposing sight.'
'Oh, there were many more of them, once,' said Molly. 'But as the land's bounty has been exhausted, the Army of Shadows' numbers have been controlled down to what you see here.'
'There are enough of their spawn in Quatershift,' said Jeanne, 'and they seemed plentiful enough to me as they overran our territory.'
Keyspierre glared at his daughter. 'You are coming close to voicing defeatist sentiments, compatriot daughter.'
'I saw the gnawed bones of our people outside Courau, compatriot father,' said Jeanne.
Keyspierre's face went red at the tone of insolence in her voice and for a moment Molly thought that he was going to strike her, but he obviously thought better of disciplining his daughter in front of them. 'Try remembering that when you see the faces of the monsters responsible for their deaths.'
'These Kals, sir, are cowards,' said Rooksby. 'With so few of the enemy's number left here, why have the natives not risen in revolt? If only we had the marines along that were meant to be here. Just a handful of them and we could have seized this pathetic hovel. Damn these Kals' eyes.'
'You'll be able to measure their bravery soon enough,' said Molly. 'If we can meet up with Kyorin's comrades.'
There was a location that burnt particularly bright in the jumbled buzz of memories that was Kyorin's legacy to her. Outside the walled city, a place where the slat soldiers rarely came. She found it easily by the presence of the seventy-foot high cacti, their leaf sails – vast moisture traps – slowly rotating. Taps had been drilled into them, but the queues of Kals had thinned out now that the previous day's collected water had slowed to a mere trickle through the plants' veins.
Molly led the four of them into the shadow of one of the emptied cacti and bade them wait cross-legged. It was ten minutes before one of the water-keepers left his plant to come over to them.
'Are you sand-born?' he asked using mind-speech. 'If the slats hear that nomads are travelling close to here and begging for water they will-'
'We are travellers,' said Molly. 'From afar.'
The water-keeper stepped back, gasping as he saw Molly's lips opening and closing to form the words.
'What did you say to him?' Rooksby demanded, watching the shocked water-keeper hustle back to his cactus and beckon his apprentices closer.
'You'll know soon enough.'
'What have you done, now, you foolish woman?' hissed Rooksby. 'Is it not enough you had to drag us here without the soldiery to finish off the Army of Shadows…'
'We'll find out soon enough if Kyorin still has friends here among the oasis regulators,' said Molly.
'This is not how such things are done,' said Keyspierre.
'I bow to a Quatershiftian's greater knowledge of how informers and the secret police work,' said Molly. 'But as I'm the only one here who can communicate in their language, we'll do this my way.'
Molly's way proved adequate, for when one of the water-keeper's assistants returned, it was with a female Kal, her face uncovered by the enveloping white headscarves the rest of them were wearing. She knelt before Molly and pressed the skin of Molly's forehead with her thumb. Molly felt a gentle tickle inside her skull, then the headache of Kyorin's memories rising. Molly winced in agony as the female Kal withdrew her thumb and rubbed it with her forefinger. There was a smudge of blue dye where the sweat of Molly's forehead had made the theatrical face paint moist.
'Clever,' said the woman. 'But do not bring your blue faces too close to any slats. They have very good nasal receptors and your scent is, I suspect, different enough from ours.'
'We are friends of the slave engineer Kyorin,' said Molly. Her head throbbed with pain. There was something about this female that was causing Kyorin's memories to thunder inside Molly.
'That much is clear. Why else would the residue of his soul burn hard inside you?' said the woman. 'And you use old speech. Keep your lips closed when we get inside the city. I shall do such communicating as may be required.' She looked at Rooksby and the two shifties and repeated her words in Jackelian.
'You understand us!' said Keyspierre.
The woman sighed, leading them away from the oasis and towards the city. 'It's quite unnerving seeing someone with blue skin speaking like a slat, all fangs and tongue and teeth. Yes, I understand Jackelian, Quatershiftian and about a dozen more of your languages. One of my family received training for a position on the expeditionary force.'
'You are our compatriots, then,' said Jeanne. 'You are fighting the Army of Shadows.'
'We resist their aims,' said the Kal, bitterly. 'While also serving duty as their slaves and food source. I am not sure if the former outbalances the latter. It would have been better if one of the plagues that followed the loss of our medical technology had wiped us out entirely, then the masters would have starved to death before they ever reached your home.'
'Does your cell's revolutionary tradecraft allow us to know your name, compatriot?' asked Keyspierre.
