He let out a slow breath, only now realizing he was lying on an ants' nest and its inhabitants were telling him to leave in no uncertain terms. I lie with the weight of a god on their world, and these ants don't like it. We're so much more alike than most would think.

Kalam edged back through the grasses. Not the first scene of horror I've witnessed, after all. A soldier learns to wear every kind of armour, and so long as he stays in the trade, it works well enough. Gods, I don't think my sanity would survive peace!

With that chilling thought seeping like weakness into his limbs, Kalam reached the back slope, out of the victims' line of sight. He scanned the area, seeking sign of Apt's presence, but the demon seemed to have vanished. After a moment he rose into a crouch and padded back to the aspen grove where the others waited.

Minala rose from cover as he approached the low brush encircling the silver-leafed trees, crossbow in her hands.

Kalam shook his head. In silence they both slipped between the spindly boles and rejoined the group.

Keneb had succumbed to yet another bout of fever. His wife, Selv, hovered over him in tight-lipped fear that seemed on the edge of panic, holding a water-soaked cloth to Keneb's forehead and murmuring in an effort to still his thrashing and twitching. The children, Vaneb and Kesen, stood nearby, studiously attending to their horses.

'How bad is it?' Minala asked, carefully uncocking the crossbow.

Kalam was preoccupied with plucking and brushing ants from his body for a moment, then he sighed. 'We'll not get around them. I saw standards from the west tribes – those camps are still growing, meaning the Odhan to the west won't be empty. Eastward we'd run into villages and towns, all liberated and occupied by garrisons. That whole horizon is nothing but smoke.'

'If it was just you you'd get through,' Minala said, reaching up to brush her black hair from her face. Her light-grey eyes held hard on him. 'Just another soldier of the Apocalypse, it would be a simple task to take picket duty on the south edge, then slip away one night.'

Kalam grunted. 'Not as easy as you think. There're mages in that encampment.' And I've held the Book in my hands – not likely I'd stay anonymous—

'What difference would that make?' Minala asked. 'Maybe you've got a reputation, but you're no Ascendant.'

The assassin shrugged. He straightened, retrieved his pack, set it down and began rummaging through its contents.

'You haven't answered me, Corporal,' Minala continued, watching him. 'Why all this self-importance? You're not the type to delude yourself, so you must be holding something back from us. Some other . .. significant detail about yourself.'

'Sorcery,' Kalam muttered, pulling free a small object from the pack. 'Not mine. Quick Ben's.' He held up the object and quirked a wry grin.

'A rock.'

'Aye. Granted, it'd be more dramatic if it was a faceted gem or a tore of gold. But there's not a mage in this world stupid enough to invest power in a valuable object. After all, who'd steal a rock?'

'I've heard legends otherwise—'

'Oh, you'll find magic embedded in jewels and such – sorcerers make up dozens of them, all cursed in some way or other. Most of them are a kind of magical spying device – the sorcerer can track them, sometimes even see through them. Claws use that intelligence-gathering method all the time.' He tossed the rock in the air, caught it, then suddenly sobered. 'This was intended to be used as a last resort...' In the palace at Unta, actually.

'What does it do?'

The assassin grimaced. I haven't a clue. Quick Ben's not the expansive type, the bastard. 'It's your shaved knuckle in the hole, Kalam. With this you can stride right into the throne room. I guarantee it.' He glanced around, saw a low, flat rock nearby. 'Get everyone ready to move.'

The assassin crouched down before the flat rock, set the stone on it, then found a fist-sized cobble. He hefted it thoughtfully before bringing it crashing down on the stone.

He was shocked as it splattered like wet clay.

Darkness swept over them. Kalam looked up, slowly straightened. Damn, I should've guessed.

'Where are we?' Selv demanded in a high, taut voice.

'Mother!'

The assassin turned to see Kesen and Vaneb stumbling in knee-deep ash. Ash that was filled with charred bones. The horses were shying, tossing their heads as grey dust rose like smoke.

Hood's breath, we're in the Imperial Warren.' Kalam found himself standing on a broad, raised disc of grey basalt. Sky merged with land in a formless, colourless haze. I could wring your neck, Quick Ben! The assassin had heard rumours that such a warren had been created and the description matched, but the tales he'd picked up on Genabackis suggested that it was barely nascent, extending no more than a few hundred leagues – if leagues mean much here – in a ring around Unta. Instead, it reaches all the way into Seven Cities. And Genabackis? Why not? Quick Ben, there could be a Claw riding your shoulder right now...
