WellA child's shrieking, echoing from up the passage, brought Trull Sengar to his feet. His spear leaned against a wall – snatching it in one hand he rushed towards the cries.

Aystar suddenly appeared, arms outflung, her face a blur of white – '

Steth's dead! He's been killed! He's dead-'

And then Minala was in the child's path, wrapping her in a fierce hug then twisting round. 'Panek! Gather the soldiers!'

The second line of defence, halfway between Onrack's position and the main encampment, was held by Ibra Gholan, and this T'lan Imass turned as Trull Sengar approached.

'Onrack battles,' Ibra Gholan said. 'To slow their advance. There are many Tiste Edur this time. And humans. A shaman is among them, an Edur, wielding chaotic power. This time, Trull Sengar, they mean to take the First Throne.'

He could hear sounds of fighting now. Onrack, alone against a mass of Trull's own kin. And a damned warlock. 'Get Monok Ochem up here, then!

If that warlock decides to unleash a wave of sorcery, we're finished.'

'Perhaps you are-'

'You don't understand, you sack of bones! Chaotic sorcery! We need to kill that bastard!' And Trull moved forward, leaving Ibra Gholan behind.

Ahlrada Ahn watched three of his warriors fall to the T'lan Imass's huge stone sword – the undead bastard had yet to take a step back from the narrow choke-point in the passage. Ahlrada Ahn turned to Sathbaro Rangar. 'We need to drive that thing back! It won't tire – it can hold that position for ever!'

Taralack Veed pushed into view. 'Send Icarium against it!'

'The Jhag is empty,' the warlock said dismissively. 'Withdraw your warriors, Ahlrada Ahn. And get those Letherii to cease with their arrows – I do not want an errant shaft in the back.' Sathbaro Rangar then moved forward.

And Ahlrada Ahn saw a figure coming up behind the T'lan Imass, a figure wielding a spear – tall, hidden in shadows, yet… a familiar silhouette, the fluid movement – he saw an arrow hiss past the undead' s shoulder, then saw that spear shaft flick it aside.

No. This cannot be. I am mistaken. 'Sathbaro!'

The T'lan Imass suddenly yielded its position, stepping back into darkness, and then it and the other figure moved away, up the passageSathbaro Rangar hobbled closer to the choke-point, power building round him, a silver-etched rising wave, flickering argent. The damp stone of the fissure's walls began snapping, a strange percussive sound as water burst into steam. A large sheet of rock near the narrowed portal suddenly exfoliated, crashing down to shatter on the floor.

The sorcery lifted higher, fuller, spreading out to the sides, then over Sathbaro's head, a standing wave of power that crackled and hissed like a thousand serpents.

Ahlrada Ahn moved forward. 'Sathbaro! Wait!'

But the warlock ignored him, and with a roar the seething wave of magic plunged into the choke-point, blistering a path up the channel-where it suddenly shattered.

The concussion pushed Ahlrada Ahn back three steps, a wave of heat striking him like a fist.

Sathbaro Rangar screamed.

As something huge appeared in the choke-point, humped shoulders pushing through the aperture. Gaunt with undeath, its skin a mottled map of grey and black, silver-tipped fur on the neck and reaching along the shoulders like hackles, the creature emerged from the chokepoint and rushed on its knuckles and hand-like hind feet – straight for Sathbaro Rangar.

Ahlrada Ahn shouted out a warning-too late, for the beast reached out and closed enormous hands on the warlock, lifted him into the air, tore off one arm, then the other, blood gouting as the apparition then twisted the shrieking Sathbaro round and bit into the back of the Edur's neck, huge canines sinking deep. As the jaws clenched, the undead demon's head snapped back – and ripped half the neck away – Sathbaro's spine racing out like an anchor-chain, whipping bloody in the airThe beast then flung the corpse aside, and advanced on Ahlrada Ahn.

Icarium stood over the corpse of a child, stared down at the fluids leaking from the broken skull, at the glazed eyes and half-open mouth.

The Jhag stood as if rooted, trembling.

Taralack Veed was before him. 'Now, Slayer. Now is the time!'

'No need,' Icarium muttered. 'No need for this.'

'Listen to me-'

'Be silent. I will not kill children. I will have none of this-'

A detonation of sorcery ahead, the concussion rolling back, rocking them both. Shouts, then screams. And a bestial snarl. Shrieks, cries of horror from the Letherii and Edur, then the sound of fear.
