Her breath caught. ‘The Beast Hold.’

He glanced at her. ‘What?’

‘The Bone Perch. Elder, Crone, Seer, Shaman, Hunter and Tracker. The Stealers of Fire. Stolen from the Eres’al.’

‘Eres’al. That’s the Nerek goddess. The false goddess, or so claimed our scholars and mages, as justification for conquering the Nerek. I am shocked to discover the lie. In any case, aren’t the images on the tiles those of beasts? For the Beast Hold, I mean.’

‘Only among the poorer versions. The skins of beasts, draped round dark, squat savages. That is what you will see on the oldest, purest tiles. Do not pretend at ignorance, Udinaas. You brought us here, after all.’

They were approaching the nearest barrows, and could see, studding the raw earth, countless objects. Broken pottery, jewellery, iron weapons, gold, silver, small wooden idols, scraps of cloth. The remnant possessions of the people buried beneath.

Feather Witch made a sound that might have been a laugh. ‘They left the treasure on the surfaces, instead of burying it with the bodies. What a strange thing to do.’

‘Maybe so looters won’t bother digging and disturbing the corpses.’

‘Oh, plenty of looters around here.’

‘I don’t know this realm well enough to say either way,’ Udinaas said, shrugging.

The look she cast him was uneasy.

Closer now, the destroyed city loomed before them. Crusted barnacles clinging to the bases of massive upright wooden pillars. Black, withered strips of seaweed. Above, the cross-sectioned profiles of framework and platforms supporting streets and buildings. And, in the massive chunks of grey, porous ice, swaths of rotting flesh – not human. Oversized limbs, clad in dull scales. A long, reptilian head, dangling from a twisted, torn neck. Entrails spilled from a split belly. Taloned, three-toed feet. Serrated tails. Misshapen armour and harnesses of leather, stretches of brightly coloured cloth, shiny as silk.

‘What are those things?’

Udinaas shook his head. ‘This city was struck by ice, even as it was torn from our world. Clearly, that ice held its own ancient secrets.’

‘Why did you bring us here?’

He rounded on her, struggled to contain his anger, and managed to release it in a long sigh. Then he said, ‘Feather Witch, what was the tile you held in your hand?’

‘One of the Fulcra. Fire.’ She faltered, then resumed. ‘When I saw you, that first time, I lied when I said I saw nothing else. No-one.’

‘You saw her, didn’t you?’

‘Sister Dawn… the flames-’

‘And you saw what she did to me.’

‘Yes.’ A whisper.

Udinaas turned away. ‘Not imagined, then,’ he muttered. ‘Not conjured by my imagination. Not… madness…’

‘It is not fair. You, you’re nothing. An Indebted. A slave. That Wyval was meant for me. Me, Udinaas!’

He flinched from her rage, even as understanding struck him. Forcing a bitter laugh. ‘You summoned it, didn’t you? The Wyval. You wanted its blood, and it had you, and so its poison should have infected you. But it didn’t. Instead, it chose me. If I could, Feather Witch, I’d give it to you. With pleasure – no, that is not true, much as I’d like it to be. Be thankful that blood does not flow in your veins. It is in truth the curse you said it was.’

‘Better to be cursed than-’ She stopped, looked away.

He studied her pale face, and around it the blonde, crinkled hair shivering in the vague, near-lifeless wind. ‘Than what, Feather Witch? A slave born of slaves. Doomed to listen to endless dreams of freedom – a word you do not understand, probably will never understand. The tiles were to be your way out, weren’t they? Not taken in service to your fellow Letherii. But for yourself. You caught a whisper of freedom, didn’t you, deep within those tiles? Or, something you thought was freedom. For what it is worth, Feather Witch, a curse is not freedom. Every path is a trap, a snare, to entangle you in the games of forces beyond all understanding. Those forces probably prefer slaves when they use mortals, since slaves understand intrinsically the nature of the relationship imposed.’

She glared at him. ‘Then why you?’

‘And not you?’ He looked away. ‘Because I wasn’t dreaming of freedom. Perhaps. Before I was a slave, I was Indebted – as you remind me at every opportunity. Debt fashions its own kind of slavery, Feather Witch, within a system designed to ensure few ever escape once those chains have closed round them.’
