They were attacked soon after. Seventy or eighty assailants came howling out of a scrawny stand of trees. Not many of them had any armour, or even proper weapons. Fearless, they swept down on Taim’s column, brandishing sickles and axes, cudgels and long knives. Many stumbled and fell in the snowdrifts; many others fell as soon as they came within reach of the Lannis men. Enough closed up to turn a short stretch of the road into a brutal little battle. Taim kept his horse on a short rein. He worked methodically, hacking down one attacker after another. It was soon over.

The further up the coast road they went, the more uneasy Taim became. He heard bursts of battle from further inland, never close or clear enough to tempt him towards them. Aewult’s great army had been engulfed and dismembered by the snowstorm. A frightened band of Haig warriors came streaming down the road from the direction of Glasbridge. Many of them were wounded, others had cast aside their weapons. As they barged their way past, Taim leaned down and seized one of them by the collar.

“What’s happening?” he demanded of the man. “Where’s the Bloodheir?”

“Who knows?” the warrior cried, and tore himself free.

More figures were rushing down the buried road in the footsteps of the fleeing Haig company. These were different, though: matted hair, hide jackets adorned with fragments of bone and ivory, long spears with extravagantly barbed points. Tarbains. Taim had fought them once or twice in his youth, when he was scouting into and beyond the Vale of Stones from Tanwrye. He knew how best to meet them. He swung his sword above his head and charged the tribesmen, crying out as he went. His men followed. The Tarbains halted. Some of them launched spears that arced down into the mass of horsemen. Breaks and contortions in the rolling thunder of hoofs told Taim that more than one of the missiles found its mark, but the Tarbains were not inclined to test their skills against mounted men. The whole ragged band of them scattered from the line of the road, streaming inland over a flat, blank white field.

Taim reined in his mount at once, and a single shouted command was enough to call back his warriors. There was no point in wasting time and the horses’ strength trying to run down Tarbains in deep snow. They had a more important purpose here. Taim allowed himself to wonder only briefly how he was supposed to fulfil that purpose, if he could not even find Aewult nan Haig. There was nothing to do put press on down the gullet of this great wintry beast.

The air was now so thick with snow that sight failed beyond two score paces. Taim’s world had collapsed to this strange, enclosed white space, beyond which strange sounds – indistinct but terrible – rose and fell. He turned his head this way and that, trying to make some sense of what he heard, but the same blurred cacophony seemed to lie all around beyond the curtain of falling snow. He glimpsed figures and raised his sword; they were gone at once, as if they had been mere momentary darkenings in the air’s featureless expanse.

His men were clustered together behind him. Their silence betrayed their apprehension. Taim peered this way and that. Even the course of the road ahead was lost, hidden beneath a white blanket. Anger – a clenched ire born out of anxiety – knotted his stomach. It was impossible to fight like this, half blind and half deaf. He had not led the survivors of Gryvan’s war against Igryn oc Dargannan-Haig all the way here just to throw their lives away.

He was on the point of turning his company back when a surge of sound reached him, holding its shape in his ear long enough for him to fix its direction. There was battle somewhere close ahead. He urged his horse forwards, gesturing for the others to keep pace with him. And soon enough there was a trail they could follow: corpses; a broad field where the snow and earth and blood had been churned into a filthy, trampled mess; and voices, screaming and shouting above the ringing of blades and shields. There was a heaving mass of figures. It was a formless thing, a dark, turbulent thundercloud pressed down by the weight of tumbling snow. Amidst it, Taim glimpsed momentary flashes of armour, a torn banner swaying back and forth like the mast of a tempest-shaken ship. It was Aewult’s Palace Shield, beset. And where his Shield was, the Bloodheir must be.

“Here you are,” Taim cried over his shoulder to his men. He rattled his sword against the face of his shield. “Here’s battle for you! Here’s the Black Road, that killed your Thane and burned your homes!”

The charge was reckless and wild, across treacherous ground strewn with the dead, through the blizzard. There was no time to tell friend from foe, only to stab and slash as they crashed into the throng of warriors. Taim’s horse reared and stamped, lunged on into the fray. Men and women went down before it. Taim swung and his blade sent someone’s helmet spinning away. A spear lanced in across the front of his hips. He hacked down on the shaft and cracked it. His shield shook, and he saw a crossbow bolt fixed there. Another spear punched into his horse’s shoulder and stayed there for a moment, dragged from its wielder’s hands. It fell away as the horse staggered, sinking, before surging up and on again. Someone – a woman – was running past, fleeing perhaps. Taim cut at the back of her neck.

He could see the Palace Shield, surrounded by a thick press of Black Road warriors. He cut his way towards them, trusting his men to follow. His horse stumbled and its forequarters plunged down. It twisted onto its side, throwing Taim. The snow was deep and it smacked, wet and cold, into his face. It filled his mouth and clung to his face. His body acted without the need for thought. He kept hold of his sword, rolled, and then he was on his feet, spitting snow, in time to turn the first spear thrust aside with his shield. Another came in from his flank, but he was already stepping back and out of its path. A backhanded swordstroke hit the spearman on the shoulder and knocked him down. In the empty, still part of his mind that took over at such moments, Taim registered his own warriors surging past, saw the mounted figure of Aewult nan Haig up ahead. He heard his horse struggling to rise behind him, spun around and flung a leg across the saddle. It bore him up.

The Lannis-Haig men broke through to what remained of Aewult’s Palace Shield. Many of the shieldmen were already dead, crumpled in the snow, their breastplates smeared with dirt and blood. The survivors were fighting desperately to keep the teeming masses of the Black Road from their master.

At first Taim was not certain whether Aewult recognised him. The Bloodheir’s eyes were wild.

“Sire, come away,” Taim shouted. His horse was tossing its head, shaking. He could not tell how badly it was injured; how much longer he had before it fell again.

“We can’t keep you safe here,” Taim cried. “There’s already fighting far behind us. We must fall back to Kolglas.”

Taim saw such loathing, such visceral hatred, in Aewult’s face then that he feared the Bloodheir was about to attack him. Instead, Aewult wheeled his massive horse and made for safety. Most of his Palace Shield broke away and followed in his wake, barging through the ranks of Taim’s men. A few of the huge armour-clad warriors were too entangled in the fray to escape so easily. Even as Taim watched, one of them went down, a long-handled axe hooking his neck and hauling him backwards out of his saddle.

Aewult was instantly out of sight, vanished into the white void that surrounded them. Taim swept snowflakes from his brow with the back of his sword hand. There was nothing to be gained by fighting on here. The Black Road warriors were too numerous, and dozens of them were already spilling out over the snowfield in pursuit of the Bloodheir.

“With me, Lannis!” Taim cried, and drove his horse after Aewult.
