There seemed little point in trying to anticipate the Wickan Fist. The historian wheeled back to the spring and stiffly dismounted, wincing at the ache in his hips and thighs, the dull throb in his lower back. He could go no farther, nor could his horse. They needed to rest – and they needed the soupy water at the bottom of the lakebed.

He removed his bedroll from the saddle, tossing it onto the leaf-strewn sand. Unhitching the mare’s girth strap, he slid the ornate saddle from its sweat-covered back. Taking the reins, he led the animal down to the water.

The spring had been plugged with rocks, which explained its slowed trickle. Duiker removed his scarf and strained the water through the fabric into his helmet. He let the horse drink first, then repeated the filtering process before quenching his own thirst and refilling his canteen.

He fed the mare from the bag of grain strapped to the saddle, then rubbed the beast down before turning his attention to setting up his own makeshift camp. He wondered whether he would ever rejoin Coltaine and the army; whether, perhaps, he was trapped in some nightmarish pursuit of ghosts. Maybe they are demons, after all. His weariness was getting the better of him.

Duiker laid out the bedroll, then rigged over it a sunshade using his telaba. Without the trees the sun would scorch this oasis – it would be years in recovering, if it ever did. Before sleep took him, he thought long on the war to come. Cities meant less than did sources of water. Armies would have to occupy oases, which would become as important as islands in a vast sea. Coltaine would ever be at a disadvantage – his every destination known, his every approach prepared for ... provided Kamist Reloe can get to them first, and how can he fail in that? He doesn’t have thousands of refugees to escort. For all the Fist’s surprises, Coltaine was tactically constrained.

The question the historian asked himself before falling asleep held a blunt finality: how long could Coltaine delay the inevitable?

He awoke at dusk, and twenty minutes later was on the trail, a solitary rider beneath a vast cloak of capemoths so thick as to blot out the stars.

Breakers rolled over a reef a quarter of a mile out, a phosphorescent ribbon beneath a cloud-filled sky. The sun’s rise was an hour away. Felisin stood on a grassy shelf overlooking a vast beach of white sand, light-headed and weaving slightly as the minutes passed.

There was no boat in sight, no sign that anyone had ever set foot on this stretch of coast. Driftwood and heaps of dead seaweed marked the tide line. Sand crabs crawled everywhere she looked.

‘Well,’ Heboric said beside her, ‘at least we can eat. Assuming those are edible, that is, and there’s only one way to find out.’
