As he emerged from the shadows, everyone within sight fell to their knees. He peered at one of the black sacs. His ranga would not allow him to reach down to it. ‘Hold it up to me.’
As a keeper lifted it, Carnelian could smell its reek even through the nosepads of his mask. ‘Naphtha.’
He let the men resume their work and stood where he could watch them ferrying the sacs over to the tower base roped to the dragon’s back. After a while a reek of naphtha began wafting down from the tower base and he realized they must be filling its tanks.
The empty sacs were piled on the cothon floor away from the dragons. No doubt as a precaution against accidental fire. Near sunset the legionaries began clearing the cothon. Carnelian had been watching the mobilization for so long, his legs had begun to ache. A lone legionary dared approach to tell him that the gates would soon be locked. Carnelian followed the man across the cothon. The rest of his comrades were already beginning to huddle around fires they had lit upon the cobbles away from the dragons. As Carnelian passed through the gate it was locked behind him.
Alone in the marumaga barracks, Carnelian could hear the murmur of the Marula in the courtyard outside. How he longed to go and join them round their campfires. Twice now he had summoned someone to attend him but, when they had knelt before him, he had stood silent. What communication could there be between them? All they could see was a Master. He had had to be content with asking them to bring food and water.
He lay on the floor without a blanket, wanting the stone to spread its coldness up to numb his heart. What would he not have given for a glimpse of Fern or Poppy or Krow, or even just to hear their voices?
Beneath one of Heart-of-Thunder’s piers, Carnelian was waiting for the Quartermaster. Though, by waking, he had escaped his nightmares, his mind was still stained with dread. The cothon and its activity no longer held a promise of power, but only of destruction. This great mechanism, so nearly wound up to readiness, was a weapon he knew Osidian would not hesitate to use. His heart told him they were close to the point of no return if, indeed, they had not already passed it. The immediate consequences of the events they were about to set in motion he could barely see; the ultimate consequences he could not see at all; but, though he was blind to the future, his heart was populating it with vague, terrible shapes.
‘My Master, you summoned me?’
It was like being shocked awake. The Quartermaster was there, kneeling. Carnelian gestured him to rise. ‘What remains to be done?’
‘Some of the dragons have not yet recovered their strength, Master, and this is causing us delays. We dare not burden them until they’re ready.’
Instinctively, Carnelian reached out to reassure the man, but let his hand fall when he saw him flinch. ‘I’m not accusing you, but seek only your best estimate of when the legion will be ready.’
‘Before nightfall most of the tanks should be full, Master.’
‘And then?’
‘For those dragons strong enough, we can attempt to seal their towers.’
Carnelian glanced at Heart-of-Thunder. ‘Is he strong enough?’
‘He is, Master.’
‘What happens after his tower is sealed?’
‘We shall connect up the pipes.’
‘The flame-pipes?’
‘Just so, Master.’ The man raised a hand to point towards the centre of the cothon.
Carnelian gazed off to what he had thought a brass wall. The Quartermaster said something else, but Carnelian was not listening. He had not noticed before how much that wall resembled the bronze forest surrounding the Chamber of the Three Lands in Osrakum.
Mast and tower shadows were reaching across the cothon when the Quartermaster came to tell him Heart-of-Thunder’s tanks were full and that his tower would now be sealed. Carnelian followed him back and found a place near the dragon where he could watch everything. Slaves greased the piers, counterweights were released, the upper, pyramid-shaped part of the tower rose from its supporting beams. When these were slid away the pyramid was left swinging gently like some vast but silent bell, men clinging to its sides. Chanting to keep their rhythm, gangs pulled the pyramid down, even as the counterweights rose in their niches in the piers. As the two parts of the tower came together, the men on its sides began threading ropes through blocks and rings. When the pyramid and base were sewn together, one by one the counterweights were coaxed onto holding shelves. Heart-of-Thunder groaned as his shoulders bulged under the increasing burden of the completed tower. Men ran around him, gazing up anxiously, testing his sinews with poles. Slowly smiles lit faces, eyes brightened, as they grew confident he was strong enough. At the Quartermaster’s command they unhitched the cradle ropes. The tower was now completely free of the piers. It and Heart-of-Thunder were one.
Legionaries escorted two flame-pipes across the cothon: each a trumpet as massive as a fallen tree. Setting guards on the piers, one of the legionaries first sent his fellows clambering up, then gave a command to the beastmaster sitting astride one of Heart-of-Thunder’s lower horns. Carnelian took a step back as the tower rocked. Under instruction, the dragon was shuffling sideways towards the pier. Legionaries began crossing to his tower. Clambering around on its sides, they threw down ropes to be hitched to one of the flame-pipes. Slowly it was hoisted towards the tower.
A commotion across the cothon made Carnelian turn to see that riders were pouring in through the outer gate. Osidian and the Marula had returned.
Carnelian waited for Osidian by Heart-of-Thunder’s pier. He watched him consult the Quartermaster and then approach, accompanied by another Master. ‘It seems, my Lord,’ Osidian called out, ‘it will be at least another day before we can leave. Some of the huimur are not yet strong enough to bear their towers.’
Carnelian tried to deduce something of Osidian’s mood from his tone, from the set of his shoulders. He sensed Osidian was putting on a show for the other Master. They all turned to gaze up at Heart-of-Thunder. The first flame-pipe was already attached. Legionaries were working on the second. Osidian was nodding. ‘I shall command the first cohort from his tower.’
He turned to Carnelian. ‘I hope that you, my Lord Suth, shall condescend to command the second.’
Carnelian had not thought about it, but raised his hand in affirmation.
‘The third we shall leave in your hands, my Lord.’ Osidian indicated the other Master, who bowed.
‘As you command, Celestial.’
Something about this man disturbed Carnelian, but he could not work out what it was. Then it occurred to him. His voice was not that of the ex-Legate. As the most senior of the Lesser Chosen it should have been he who took next place after Osidian and himself.
Later, as he followed Osidian to where the other Lesser Chosen were waiting, Carnelian searched among them for one who might be behaving differently from the others, perhaps showing some resentment. It was then he noticed ammonites unloading a body from a saddle-chair. He glimpsed an arm that was wrapped in ritual bindings.
‘You murdered him, didn’t you?’ Carnelian asked, the moment they were alone and unmasked.
Osidian gazed at him. ‘He defied me.’
‘You needed to kill him as an object lesson to the other commanders.’
Osidian held Carnelian’s glare for a while before turning away as he divested himself of his military cloak. ‘We shadowed the road far to the west and saw no sign of Aurum.’
Carnelian was remembering how Osidian had killed Ranegale so as to take control of the Ochre raiding party. He focused his attention on what Osidian had said. ‘What if he does not come by road?’
