As for her, she found herself viewing her surroundings in terms of trees left unharvested, of lakes still rich with fish, of more efficient ways to gather the elongated, mud-coloured grains from the reed beds in the shallows – the so-called black grain that needed to be beaten free of the stalks, gathered in the hollow of the long, narrow-boats the Anibar used, beaten down with sticks amidst webs and spinning spiders and the buzz of tiger-flies. She could think only of resources and the best means of exploiting them. It felt less and less like a virtue with every passing day.

They continued along the trail, Boatfinder in the lead, followed by Karsa who led his horse by the reins, leaving Samar Dev with a view of the animal's rump and swishing tail. Her feet hurt, each step on the hard stone reverberating up into her spine – there had to be a way of padding such impacts, she told herself, perhaps some kind of multilayering technology for boot soles – she would have to think on that.

And these biting flies – Boatfinder had cut juniper branches, threading them through a headscarf so that the green stems dangled in front of his forehead and down the back of his neck. Presumably this worked, although the man looked ridiculous. She contemplated surrendering her vanity and following suit, but would hold out a while longer.

Karsa Orlong was undertaking this journey now as if it had become some kind of quest. Driven by the need to deliver judgement, upon whomsoever he chose, no matter what the circumstances. She had begun to understand just how frightening this savage could be, and how it fed her own growing fascination with him. She half-believed this man could cut a swath through an entire pantheon of gods.

A dip in the trail brought them onto mossy ground, through which broken branches thrust up jagged grey fingers. To the right was a thick, twisted scrub oak, centuries old and scarred by lightning strikes; all the lesser trees that had begun growth around it were dead, as if the battered sentinel exuded some belligerent poison. To the left was the earthen wall of a toppled pine tree's root-mat, vertical and as tall as Karsa, rising from a pool of black water.

Havok came to an abrupt halt and Samar Dev heard a grunt from Karsa Orlong. She worked her way round the Jhag horse until she could clearly see that wall of twisted roots. In which was snared a withered corpse, the flesh wrinkled and blackened, limbs stretched out, neck exposed but of the head only the lower jaw line visible. The chest area seemed to have imploded, the hollow space reaching up into the heart of the huge tree itself. Boatfinder stood opposite, his left hand inscribing gestures in the air.

'This toppled but recently,' Karsa Orlong said. 'Yet this body, it has been there a long time, see how the black water that once gathered about the roots has stained its skin. Samar Dev,' he said, facing her, 'there is a hole in its chest – how did such a thing come to be?'

She shook her head. 'I cannot even determine what manner of creature this is.'

'Jaghut,' the Toblakai replied. 'I have seen the like before. Flesh becomes wood, yet the spirit remains alive within-'

'You're saying this thing is still alive?'

'I do not know – the tree has fallen over, after all, and so it is dying-'

'Death is not sure,' Boatfinder cut in, his eyes wide with superstitious terror. 'Often, the tree reaches once more skyward. But this dweller, so terribly imprisoned, it cannot be alive. It has no heart. It has no head.'

Samar Dev stepped closer to examine the body's sunken chest. After a time she backed away, made uneasy by something she could not define. '

The bones beneath the flesh continued growing,' she said, 'but not as bone. Wood. The sorcery belongs to D'riss, I suspect. Boatfinder, how old would you judge this tree?'

'Frozen time, perhaps thirty generations. Since it fell, seven days, no more. And, it is pushed over.'

'I smell something,' Karsa Orlong said, passing the reins to Boatfinder.

Samar Dev watched the giant warrior walk ahead, up the opposite slope of the depression, halting on the summit of the basolith. He slowly unslung his stone sword.

And now she too caught a faint sourness in the air, the smell of death. She made her way to Karsa's side.

Beyond the dome of rock the trail wound quickly downward to debouch on the edge of a small boggy lake. To one side, on a slight shelf above the shoreline, was a clearing in which sat the remnants of a rough camp – three round structures, sapling-framed and hide-walled. Two were half-burnt, the third knocked down in a mass of shattered wood and torn buckskin. She counted six bodies lying motionless here and there, in and around the camp, one face-down, torso, shoulders and head in the water, long hair flowing like bleached seaweed. Three canoes formed a row on the other side of the trail, their bark hulls stove in.
