The river was a thin, narrow strip six hundred paces ahead, studded with boulders and lined in thorny brush on both sides. A trader track marked the traditional place of crossing, then wound westward to what had once been a gentle slope to the opposite ridge – but Reloe’s sappers had been busy: a ramp of sandy earth had been constructed, the natural slope to either side carved away to create a steep, high cliff. To the south of the lake bed was a knotted jumble of arroyos, basoliths, screes and jagged outcroppings; to the north rose a serrated ridge of hills bone white under the sun. Kamist Reloe had made sure there was only one point of exit westward, and at the summit waited his elite forces.

‘Hood’s breath!’ muttered Corporal List. ‘The bastard’s rebuilt Gelor Ridge, and look to the south, sir, that column of smoke – that was the garrison at Melm.’

Squinting that way, Duiker saw another feature closer at hand. Set atop a pinnacle looming over the southeast end of the lake bed was a fortress. ‘Who did that belong to?’ he wondered aloud.

‘A monastery,’ List said. ‘According to the only map that showed it.’

‘Which Ascendant?’

List shrugged. ‘Probably one of the Seven Holies.’

‘If there’s anyone still in there, they’ll get quite a view of what’s to come.’

Kamist Reloe had positioned forces down and to either side of his elite companies, blocking the north and south ends of the basin. Standards of the Sialk, Halafan, Debrahl and Tithansi contingents rose from the southern element; Ubari the northern. Each of the three forces outnumbered Coltaine’s by a large margin. A roar began building from the army of the Apocalypse, along with a rhythmic clash of weapons on shields.

The marines marched towards the crossing in silence. Voices and clangour rolled over them like a wave. The Seventh did not falter.

Gods below, what will come of this?

The River P’atha was an ankle-deep trickle of warm water, less than a dozen paces across. Algae covered the pebbles and stones of the bottom. The larger boulders were splashed white with guano. Insects buzzed and danced in the air. The river’s cool breath vanished as soon as Duiker stepped onto the opposite bank, the basin’s baked heat sweeping over him like a cloak.

Sweat soaked the quilted undergarment beneath his chain hauberk; it ran down in dirty runnels beneath gauntlets and into the historian’s palms. He tightened his grip on the shield strap, his other hand resting on the pommel of his short sword. His mouth was suddenly bone dry, though he resisted the urge to drink from his flask. The air stank of the soldiers he followed, a miasma of sweat and fear. There was a sense of something else, as well, a strange melancholy that seemed to accompany the relentless forward motion of the company.
