His memories remained sharp, and in his mind he once again strode across the plain. The ruins of the trader town where he'd been born were now visible. A month had passed since its destruction. The bodies of the fifteen thousand slain – those that had not burned in the raging fires – had long since been picked clean by the plain's scavengers. He was returning home to bleached bone, fragments of cloth and heat-shattered brick.

The ancient shoulder-women of his adopted clan had divined the tale from the flat bones they burned, as the Nameless Ones had predicted months earlier. While the Trell of the towns had become strangers to them all, they were kin. The task that remained was not, however, one of vengeance. This pronouncement silenced the many companions who, like Mappo, had been born in the destroyed town. No, all notions of vengeance must be purged in the one chosen for the task ahead. Thus were the words of the Nameless Ones, who foresaw this moment.

Mappo still did not understand why he had been chosen. He was no different from his fellow warriors, he believed. Vengeance was sustenance. More than meat and water, the very reason to eat and drink. The ritual that would purge him would destroy all that he was. You will be an unpainted hide, Mappo. The future will offer its own script, writing and shaping your history anew. What was done to the town of our kin must never happen again. You will ensure that. Do you understand?

Expressions of dreadful necessity. Yet, without the horrific destruction of the town of his birth Mappo would have defied them all. He'd walked the overgrown main street, with its riotous carpet of weeds and roots, and had seen the glimmer of sun-bleached bones at his feet.

Near the market round, he discovered a Nameless One awaiting him, standing in the clearing's centre, grey-faded robes flickering in the prairie wind, hood drawn back to reveal a stern woman's visage. Pale eyes met his as he approached. The staff she held in one hand seemed to writhe in her grip.

'We do not see in years,' she hissed.

'But in centuries,' Mappo replied.

'It is well. Now, warrior, you must learn to do the same. Your elders shall decree it so.'

The Trell slowly gazed around, squinting at the ruins. 'It has more the feel of a raider's army – it's said that such forces exist south of Nemil—'

Her sneer surprised him with its unveiled contempt. 'One day he shall return to his home, as you've done here and now. Until that time, you must attend—'

'Why me, damn you!'

Her answer was a faint shrug.

'And if I defy you?'

'Even that, warrior, will demand patience.' She raised the staff then, the gesture drawing his eye. The twisting, buckling wood seemed to reach hungrily for the Trell, growing, filling his world until he was lost in its tortured maze.

'Strange how a land untravelled can look so familiar.'

Mappo blinked, the memories scattered by the sound of that familiar soft voice. He glanced up at Icarium. 'Stranger still how the mind's eye can travel so far and so fast, yet return in an instant.'

The Jhag smiled. 'With that eye you might explore the entire world.'

'With that eye you might escape it.'

Icarium's gaze narrowed as he scanned the rubble-strewn sweep of desert below. They'd climbed a tel the better to see the way ahead. 'Your memories always, fascinate me, since I seem to have so few of my own, and more so since you have always been so reluctant to share them.'

'I was recalling my clan,' Mappo said, shrugging. 'It is astonishing the trivial things one comes to miss. Birthing season for the herds, the way we winnowed the weak in unspoken agreement with the plains' wolves.' He smiled. 'The glory I earned when I'd snuck into a raiding party's camp and broken the tips of every warrior's knife, then sneaked back out with no-one awakening.' He sighed. 'I carried those points in a bag for years, tied to my war belt.'

'What happened to them?'

'Stolen back by a cleverer raider.' Mappo's smile broadened. 'Imagine her glory!'

'Was that all she stole?'

'Ah, leave me some secrets, friend.' The Trell rose, brushing sand and dust from his leather leggings. 'If anything,' he said after a pause, 'that sandstorm has grown a third in size since we stopped.'

Hands on his hips, Icarium studied the dark wall bisecting the plain. 'I believe it has marched closer, as well,' he said. 'Born of sorcery, perhaps the very breath of a goddess, its strength still grows. I can feel it reaching out to us.'

'Aye.' Mappo nodded, repressing a shiver. 'Surprising, assuming that Sha'ik is indeed dead.'
