Trull heard its squeal of pain.

Flickering magic swarmed the demon as it spun round and toppled, sliding down the blood-soaked slope, the mace tumbling away.

Other demons had appeared among the remnants of the Letherii soldiery, flailing bodies flying from their relentless path.

Another wave of sorcery, this time from somewhere to the southeast, a rolling column, crackling with lightning as it swept crossways on the killing field, plunging into the advancing ranks of wraiths. They melted in their hundreds as the magic tore through them.

Then the sorcery struck Hanradi Khalag’s warriors, scything a path through the press.

The Merude chief’s son counter-attacked, another surge of grey, tumbling bones. A rampart to the east vanished in a thunderous detonation, but hundreds of Edur lay dead or dying on the field.

Deafened, half-blinded by dust and smoke, Trull and his warriors reached the slope, scrambled upward and came to the first trench.

Before them stretched an elongated pit filled with unrecognizable flesh, split bones and spilled organs, strips of leather and pieces of armour. The air was thick with the stench of ruptured bowels and burnt meat. Gagging, Trull stumbled across, his moccasins plunging down into warm pockets, lifting clear sheathed in blood and bile.

Ahead, a raging battle. Wraiths swarming over soldiers, demons with mauls and maces crushing the Letherii closing on them from all sides, others with double-bladed axes cleaving wide spaces round themselves. But ballista quarrels were finding them one by one. Trull watched a demon stagger, twice impaled, then soldiers rushed in, swords hacking.

And then he and his company closed with the enemy.

Moroch Nevath stumbled through the dust, the screaming soldiers and the fallen bodies, bellowing his prince’s name. But Quillas was nowhere to be seen. Nor was Janall. Only one mage remained from the cadre, launching attack after attack on some distant enemy. A company of heavy infantry had moved up to encircle her, but they were fast dying beneath an onslaught of Tiste Edur.

The Finadd, blood draining from his ears after the concussion of the wave of bones, still held his sword, the Letherii steel obliterating the occasional wraith that ventured near. He saw one Edur warrior, the spear a blur in his hands, leading a dozen or so of his kin ever closer to the surviving mage.

But Moroch was too far away, too many heaving bodies between them, and he could only watch as the warrior broke through the last of the defenders and lunged at the mage, driving his spear into her chest, then lifting her entire, the spear-shaft bowing as he flung her spasming body to one side. The iron point of the spear broke free in a stream of blood.

Reeling away, Moroch Nevath began making his way to the south slope of the rampart. He needed a horse. He needed to bring the mounts closer. For the prince. The queen.

Somewhere to the east, a roar of sound, and the ground shook beneath him. He staggered, then his left leg swept out, skidding on slime, and something snapped in the Finadd’s groin. Pain lanced through him. Swearing, he watched himself fall, the ruptured ground rising in front of him, and landed heavily. Burning agony in his left leg, his pelvis, up the length of his spine. Still swearing, he began dragging himself forward, his sword lost somewhere in his wake.

Bones. Burning, plunging from the sky. Bodies exploding where they struck. Crushing pressure, the air roiling and screaming like a thing alive. The sudden muting of all noise, the outrageous cacophony of grunts as a thousand men died all at once. A sound that Moroch Nevath would never forget. What had the bastards unleashed?

The Letherii were broken, fleeing down the south slope of the rampart. Wraiths dragged them down. Tiste Edur hacked at their backs and heads as they pursued. Trull Sengar clambered onto a heap of corpses, seeking a vantage point. To the east, on the two berms that he could see, the enemy were shattered. Jheck, veered into silver-backed wolves, had poured up from the gully alongside a horde of wraiths to assault what had survived of the Letherii defences. Mage-fire had ceased.

In the opposite direction, B’nagga had led his own beasts south, skirting the foremost rampart, to attack the reserve positions on the west side of the city. There had been enemy cavalry there, and the horses had been driven to panic by the huge wolves rushing into their midst. A dozen demons had joined the Jheck, forcing the Letherii into a chaotic retreat that gathered up and carried with it the southernmost elements. Companies of Arapay Edur were following in B’nagga’s wake.

Trull swung to face north. And saw his brother standing alone above a body, on the far side of the killing field.

The K’risnan.

‘Trull.’

He turned. ‘Ahlrada Ahn. You are wounded.’
