Closer now, the horse careering up to the outskirts of the village, he saw a woman clutching a child - Maeren and Rouari? - dash inside the church as Preacher Mallein was cut down by a flurry of lethal splinters fired from alien rifles. Whooping warriors in close-fitting armour of black and red somersaulted from the decks of their vehicles and sprinted through the township, firing long barrelled guns from the hip.

He shouted in horror as he saw the villagers gunned down where they stood, women and children running towards the church, their bodies jerking in the fusillade. Black smoke boiled skyward as more buildings burned and the screams of the dying cut Gedrik like a knife. Small arms fire blasted from a few windows, felling a number of the alien raiders and he knew the invaders would not take Morten's Reach without a fight.

His wild charge had carried him almost to the river, close enough to see old Gohbar ran screaming towards a group of the alien warriors, a flensing halberd raised above his head. The aliens turned and laughingly despatched the slaughterman with a volley from their deadly rifles before disappearing into the smoke of the village's death throes.

Gedrik willed his horse ever faster as he thundered across the river bridge, beside the generator mill he had helped build with his own hands, and passed the convulsing Gohbar. The man's face was purple and distended, his tongue protruding from his mouth like a swollen black snake. The entire town was in flames, the heat and smoke intolerable.

Gedrik emerged into the settlement's square, stopping his horse violently. Two of the attackers' craft hovered before the temple, the alien warriors dragging screaming townspeople towards them. Their faces were exquisitely cruel and pale: humanoid, yet wholly alien. Gedrik stood forward in the stirrups and aimed his rifle at one of the red armoured invaders, placing its angled helm squarely between his sights.

He squeezed the trigger, punching the warrior from its feet, sending blood jetting from its neck. The others scattered and Gedrik yelled out, hammering his spurs into his mount's flanks. The horse leapt forwards and Gedrik fired twice more, pitching another two aliens to the ground before the rifle jammed.

The aliens turned their weapons on him, but the Emperor was with him and their whickering ammunition flew wide of the mark. Then he was amongst them and swung his rifle in a brutal arc, smashing an enemy's skull to shards. He dropped the gun and drew his sword. He caught a flash of red, before a bolt of dark light blasted his horse from under him.

Kicking his feet free of the stirrups, Gedrik jumped from the dying beast and landed lightly before a knot of the alien warriors and lashed out with his shimmering, broad bladed sword.

The first fell with its guts looping around its ankles and the second died with Gedrik's sword lodged deep in its chest. Their alien armour was no protection against the preternatural sharpness of Gedrik's sword, which cut through it with ease. The third thrust with a smoking blade on the end of its rifle and Gedrik dodged backwards, losing his grip on the sword. The alien advanced slowly, emotionless behind its smooth-faced helm.

Gedrik snarled and dived towards his foe. He rolled beneath the alien's weapon, dragging his dagger from his boot and hammering it through the warrior's calf. The alien fell, shrieking horribly, and Gedrik wrenched the knife free, plunging it repeatedly through the alien's chest.

He saw Faergus following him, blasting two of the aliens to bloody rags with a thunderous blast of his shotgun. Faergus wheeled his horse as Gedrik retrieved his sword and shouted to his cousin.

'Get everyone you can inside the temple. We'll try to hold them from there!'

Faergus nodded, but before he could move, a flaring wash of violet fire blasted from one of the alien vehicles and engulfed him. Faergus screamed as the horrifying energies burned the flesh from his frame in moments. Slowly his charred skeleton toppled from the shrieking horse and Gedrik felt his stomach lurch at his cousin's terrible death. The horse toppled, a bloody gouge burned through the beast's flank where the alien weapon had struck.

Gedrik bounded up the steps of the temple, hammering on the door, shouting out Maeren's name. Splinters were blasted from the building as more aliens converged on the centre of the village, firing wildly towards him. He dived from the steps and rolled to his feet. He saw the surviving inhabitants driven before the aliens to their deaths and, watching it all, a slender, white haired figure in jade green armour atop the lead vehicle.

The figure slashed his huge axe impatiently through the air and Gedrik screamed as his people were shot down where they stood. He wanted to plant his dagger in the alien leader's chest, but knew he would be dead before he got close.

He ducked back, knowing that the people inside the temple could not risk opening the doors now and sprinted around the side, hoping that they had not yet barred the vestry.

Gedrik heard the bark of commands being issued and a deep bass rumble of a powerful weapon. He prayed that someone had managed to send a warning to the nearby communities.

The vestry door was just ahead and he cried in relief as he saw it was still ajar. He skidded to a halt before it and gripped the iron handle.

Before he could pull the door open, the temple exploded, roiling orange flames mushrooming skyward and blasting Gedrik from his feet. Pain like nothing he had ever known engulfed him as the blast smashed him into the hillside behind the building. He flopped like a boneless creature, shocked to his very bones by the impact. His skin burned, patches of his anatomy exposed to the elements by the unnatural flames.

He sensed cool snow upon his body, but could feel no pain.

He knew that was bad. Pain meant life.

He rolled his eyes towards the smoking wreckage of the temple, timber columns poking upwards like blackened ribs. He couldn't make out any bodies, but knew that no one could have survived the explosion and grief swamped him.

Maeren, Rouari, Faergus, Mallein, Gohbar… all gone. Everyone was dead. Even him soon.

His breath rattled in his throat as he heard the low humming of the alien vehicles approaching and he tried to push himself upright, but his limbs would not obey him. Dimly he heard the aliens' sing-song voices, elegant but threatening, and tried to spit a defiant curse. But the voices passed him, climbing the Hill of the Metal. He watched as the green-armoured warrior pointed at the hillside and directed his warriors to spread out. He heard their voices chatter excitedly, but could not understand what they said. Was this the reason his community had been slaughtered?

For the Metal?

He heard the whoosh of flames and the hillside lit up, hissing as the snow flashed to steam. The aliens continued to work the flames of their weapons across the hillside, only stopping when a hooded figure wearing shimmering red robes climbed down from the nearest alien vehicle and raised its hand. The figure stepped forward to examine what had been revealed beneath the snow and a low gasp went up from the aliens as the steam dissipated.

Swirling like quicksilver, the exposed strata sparkled in the sunlight, its entire flank shining with a metallic sheen. Beneath the snow, a whole swathe of the hillside was formed from a smooth, silver metal. It rippled and twisted like a liquid where it had run molten under the heat of the flames, undulating like a living thing. Slowly it began reshaping itself, flowing with swirling currents into a smooth, glass-flat surface until it resembled a gigantic mirror. Gedrik watched as the hooded figure dropped to its knees before the metallic hillside and began chanting in rapture, the words rasping and artificial.
