Five days after his return from the Green Gate, with Legions at his side, Carnelian watched another embassy of the Great approach. Shadowy they looked, deprived of most of their pomp by the ritual protection. The only signs of their wealth were the jewels that sparkled and gleamed on their hands and the unearthly serenity of their masks. Because of the rain, Carnelian had chosen to site the audience in one of the Gate’s chambers-of-returning. Pools spangled arches with wavering light. Man-shaped hollows stood round them in the brass walls. An odour of camphor almost occluded Legions’ aura of stale myrrh. They had agreed to confront the embassy together because they knew the Great were coming to complain. They knew also that whatever was said there would determine the mood that would prevail throughout the coombs. Carnelian feared panic spreading among the Masters at least as much as did the Wise.
Legions had informed him that the Clave had met the day before and had sent another embassy to the Labyrinth to beg an audience with the God Emperor, but had been turned away. To Carnelian’s surprise Legions had answered his questions about Osidian. It seemed that, on the day they had fled from the Green Gate, Osidian had woken from a period of tortured dreaming, too confused and disorientated to deal with the Great. Carnelian had revealed to Legions what he knew about the maggot infestation: that, probably, Osidian would be in this state for some time and might then fall into unconsciousness from which he would emerge only when the worms came out from his flesh.
The Great were upon them, several of them speaking at once. Carnelian was made wary by their lack of decorum. Making no attempt to portray unity, they were complaining of how little food was left. Seventeen days. Less. He could feel that their hauteur concealed uncertainty, fear even. He watched them as the Grand Sapient explained about the mustering of the legions. They seemed to grow taller as they contemplated the fiery brushing away of the sartlar blockade. Carnelian noted that no mention was made of the broken heliograph link to the outer world. When Legions declared that there was no prospect of any immediate relief, the Masters drew back like cobras.
He continued: ‘You should not expect the Canyon to be open again for at least a month.’
The Masters’ hands sketched angry gestures. Their ire ignited into bitter complaint, but, again, underlying this demonstration, Carnelian could sense their fear and that increased his dismay at how they might vent this upon their slaves.
‘There is another matter,’ said one. ‘The level of the Skymere rises.’
‘By three hand-breadths,’ said another.
‘Four!’
‘Many low-lying palaces will be flooded.’
‘I myself have had to evacuate a suite of halls.’
‘Are we now also to be washed from our coombs?’
Carnelian found their talk connecting to some core of unease inside him. The terrible, recurring forms of his nightmares seemed to rear at the edges of his vision.
‘Clearly, the Cloaca is not draining properly,’ sang Legions’ homunculus.
‘The corpses of the sartlar we cleared from before the Gate have dammed the flow,’ Carnelian said. Even as his voice was making promises to do something about it he was brooding over how it was that Osrakum was being threatened with a flood by the dead.
Carnelian pulled a fold of his military cloak over the nostrils of his mask, but it was not enough to dull the miasma. To his right rose a bronze grille, acid green mottled with black, streaked with the excrement of the anvil-headed sky-saurians that roosted above it in the shadows. The grille was a defence against any attackers making their way up the Cloaca. Above, a stair scaled the ravine wall, becoming a vague scratch lost in the blackness lurking beneath the bridge that linked the killing field to the outer Canyon. Up there was a door from which a passage joined the supply tunnel that ran from the Blood Gate to the Prow. It was along that route they had come to this stinking sewer.
Barring the opening between the grille and the Cloaca bed was a massive portcullis clogged with filth. In slots cut into the walls on either side, Ichorians were greasing the tracks in which ran the counterweights that controlled the portcullis. Eventually, it would have to be raised. Reluctantly, Carnelian looked upstream to where the Cloaca was choked by the immense corpse dam.
In the Cloaca, his feet squelched deep into a stinking putty. On the opposite wall, superimposed tidelines showed the levels where water had run. Through the portcullis, he could make out the Cloaca curving left, out of sight. He lingered, trying to resolve a feeling that he had seen this place before, then turned to face the dam. He began wading towards it through the filth, the fetor so thick it was almost a physical barrier.
The slope rising before him was like the midden mound beneath Qunoth, though immeasurably vaster. Of corpses, mouldering, mulching down to squeeze out their juices which were licking around his feet. He surveyed that mountain, judging the labour needed to release the waters it was damming. When he had stood upon the Blood Gate tower so far above, gazing down, it had seemed a simple thing to describe the opening they must make, as if with a single sword-cut. Sapients had described how, given a narrow channel through, the pent-up fury of the lake waters would quickly flush the whole mass away. Standing before it, Carnelian found it harder to believe their plan could work.
Around him, Ichorians, chins soiled with vomit, were trying not to see the limbs, the rotting faces in the mound they were going to have to dig through. Carnelian knew his impulse to work alongside them was inappropriate.
Climbing back up to the Blood Gate, he released more Ichorians and sent them down to the Cloaca. Thereafter, each day, standing among the mute heliographs, he watched them labouring far below in those sewers. Sometimes, when the breeze died, the charnel stench reached even his eyrie. Too slow the work, too slow for him so that, in desperation, he denuded the Gate of its garrison. Legions’ Thirds protested that he was compromising their defences, but he held his ground, stating that the Prow could break up any sartlar surge long enough for the Ichorians to return to their posts.
Judging progress still too slow, Carnelian sent a command that work in the northern branch was to be abandoned and all effort concentrated on the southern. The Cloaca haunted his dreams. He longed to see its disgusting blockage flushed away as much as if it were a clot in his own arteries.
Infrequently, messages were heliographed from the Labyrinth. One reported that the God Emperor had slipped into a sleep from which he could not be woken. Knowing Osidian would soon wake, Carnelian wondered how he would react to what had been happening while he slept. In darker moments Carnelian brooded as to who it was who would emerge from such terrible dreams wearing the face of a god. At last, one of the Thirds came to inform him the God Emperor had taken up residence in the Stone Dance of the Chameleon. The Sapient had no answers for Carnelian’s questions. He said only that Osrakum was now hungry. When Carnelian learned that Osidian had been deaf to the appeals of the Wise that the render in the Red Caves should be distributed to the coombs, he authorized it himself. That night, Fern and he stood on the summit of the South Tower in a world made frosty by a full moon. The only warmth came from the patch of gold that flickered in the Cloaca far below where the Ichorians had made their camp. Though both were starving, neither could stomach eating render.
One morning Carnelian woke feeling that a burden had lifted from his heart. He went to stand upon their balcony as had become his habit. Night still filled the Cloaca. He raised his eyes towards the open Canyon. His glance hardened to a stare of scrutiny. He called into the cell for Fern to join him. When he came, tousled, bleary-eyed, Fern confirmed what Carnelian already believed. Their spirits soared. The sartlar were gone.
Carnelian watched Ichorians scurrying along the Cloaca bed to clamber up into the counterweight slots. He could imagine how they were struggling to raise the portcullis. Filthy water was already gushing out of the channel they had delved in the corpse dam. As the stream widened, the edges of the channel crumbled into it like a sandbank into water escaping to the sea. The rush roared as it snagged more and more corpses and swirled them off along the channel. Carnelian felt it all as a physical release.
