Indeed, he could smell the grey-skinned Edur – they had passed this way, and recently, arriving from another warren. Of course, the word ‘smell’ had acquired new meaning for the T’lan Imass in the wake of the Ritual. Mundane senses had for the most part withered along with flesh. Through the shadowed orbits of his eyes, for example, the world was a complex collage of dull colours, heat and cold and often measured by an unerring sensitivity to motion. Spoken words swirled in mercurial clouds of breath – if the speaker lived, that is. If not, then it was the sound itself that was detectable, shivering its way through the air. Onrack sensed sound as much by sight as by hearing.

And so it was that he became aware of a warm-blooded shape lying a short distance ahead. The wall here was slowly failing. Water spouted in streams from fissures between the bulging stones. Before long, it would give way entirely.

The shape did not move. It had been chained in place.

Another fifty paces and Onrack reached it.

The stench of Kurald Emurlahn was overpowering, faintly visible like a pool enclosing the supine figure, its surface rippling as if beneath a steady but thin rain. A deep ragged scar marred the prisoner’s broad brow beneath a hairless pate, the wound glowing with sorcery. There had been a metal tongue to hold down the man’s tongue, but that had dislodged, as had the straps wound round the figure’s head.

Slate-grey eyes stared up, unblinking, at the T’lan Imass.

Onrack studied the Tiste Edur for a moment longer, then he stepped over the man and continued on.

A ragged, withered voice rose in his wake. ‘Wait.’

The undead warrior paused and glanced back.

‘I – I would bargain. For my freedom.’

‘I am not interested in bargains,’ Onrack replied in the Edur language.

‘Is there nothing you desire, warrior?’

‘Nothing you can give me.’

‘Do you challenge me, then?’

Tendons creaking, Onrack tilted his head. ‘This section of the wall is about to collapse. I have no wish to be here when it does.’

‘And you imagine that I do?’

‘Considering your sentiments on the matter is a pointless effort on my part, Edur. I have no interest in imagining myself in your place. Why would I? You are about to drown.’

‘Break my chains, and we can continue this discussion in a safer place.’

‘The quality of this discussion has not earned such an exercise,’ Onrack replied.

‘I would improve it, given the time.’

‘This seems unlikely.’ Onrack turned away.

‘Wait! I can tell you of your enemies!’

Slowly, the T’lan Imass swung round once more. ‘My enemies? I do not recall saying that I had any, Edur.’

‘Oh, but you do. I should know. I was once one of them, and indeed that is why you find me here, for I am your enemy no longer.’
