He reached out and, as the Ants continued fighting all around him, he put his back to the skewed machine and forced it up, working to free one of his brother artificers from under its weight.

Skrill was yelling again, and he glanced around in time to see the city wall by the gate begin to shift. He suddenly felt so very calm about it, because he was right in the wall’s shadow, and there was nothing he could do about it in time.

Stones began to bulge out of it, only one at first, and then in whole fistfuls. A man emerged: Totho could see his shape by the light of the fires, but it seemed impossible, for it was a man ten feet tall, armoured in great metal plates and wielding an eight-foot mattock. There were others behind him, and they lumbered out of the gap as still more Ants rushed in to engage them. Just before they clashed Totho was struck by the expression of hopeless misery on those giants’ faces.

The huge creature in the lead swept his spade-headed spear around him like a club, flinging three or four of the Ants aside with ruined shields, but then the soldiers were on him, and their attack-insects as well. Totho watched with numb amazement, seeing how easily the giants fell. There were Wasps following behind them though, armoured Sentinels pressing forward, their plate-mail easily turning the swords of the defenders. Some dozen of them plunged into the Ant line and shattered it, even as the last giant fell, and then there were savages bursting out along with them, shrieking and casting their spears. Behind them, in turn, came the armoured Wasp infantry, already lancing out with its stings.

Totho felt the fallen man he held stir in his arms and he forced the ruined engine an inch further off him. The man clutched at him as Totho pulled him free, now seeing the wreckage the fallen engine had made of his legs.

With conflict still all about him he dragged the dying man away, aware only that this was an artificer, and therefore a brother in craft.

‘My queen!’ the man cried. ‘I am done at last.’

Totho lowered him to the ground. He felt cold and getting colder, but his eyes found Totho’s. ‘You, Lowlander… I am sorry-’

Totho nodded, not knowing what to say. The man’s hands tugged at his coat, and perhaps there was some returning recognition there, on feeling the pockets lined with tools. ‘You must know… the air… airships! It is the end. I have… died for them, never to be home again. But the airships… you must guard…!’

There was nothing more said, just one more death amidst so many.

Salma dived through the sky like a mad thing, slashing at every Wasp that came near him, though missing most of them. The aerial forces of Tark were token only. They had their orthopters and their flying insects, but coming against them the entire sky was dense with Wasps.

He pulled out of his dive on coming level with a handful of the winged ants. Ahead of them a mass of the Wasp savages was gathering like a cloud, spiralling upwards. Salma looked over to the lead Ant rider, and for a moment there was a touch of mindlink with him, two soldiers in perfect accord, as if he saw the man’s thoughts and passed back his own.

You lead, we follow, was the man’s message, because Salma was vastly more at home in the air than they were.

Sword extended, Salma kicked out towards the circling Hornets, sword extended, and he got close, very close, before they even saw him. Then crossbow bolts from the insect-mounted weapons started punching into the flight of Wasps and they scattered wildly. Salma veered to the left, seeing spears and bolts of light dash past him. Briefly something caught his eye about their formation, then he was lancing through them, bloodying his sword on at least three before turning to dance back towards them. The insects were on them by now, thrumming heavily through the air, jaws clacking at their nimbler opponents. The crossbows were never silent, funnel-fed bolts from their hoppers cracking out every second into the mass of the enemy. Then two of the insects were down and in a moment Salma saw why.

The Ants were not the only airborne cavalry deployed above the field. Diving directly past his view came a giant wasp the size of a horse, with a soldier clinging gamely to its back. There was no crossbow, in fact no weapon at all, but the man’s hands yanked and tugged to get the monster to cooperate. It dodged and spun in the air and then fell on one of the ant-riders, lancing the insect he rode on with its sting, and crushing the rider’s shoulder with wedge-shaped jaws.

Another buzzed past, spinning Salma in its wake. Its rider tried to let loose his energy sting, but the beast began bucking the moment he took a hand from its harness. And then he was gone, and Salma was slicing through the air towards the scattered savages.

He saw what had snagged his attention before. There was a leader amongst them, a man in a spike-fronted helm bawling out orders that sent them hurtling across the city. Salma adjusted his angle, so as to come in from above and put his sword through their commander.

Colonel Edric continued sending his Hornet soldiers out to loot and burn, to create as much confusion as possible, when one of the men pointed over his shoulder and began shouting a warning. Edric turned in the air, wings dancing, to see a man – a Commonwealer! – almost upon him. He threw himself aside, losing his hold in the air and dropping ten feet before his Art caught him, and the Dragonfly flashed past him, slicing open the soldier who had warned him. Edric was after the Commonwealer in a moment, knowing that a score of Hornets would follow faithfully, and then had to hurl himself backwards as a great dark shadow roared down from above. It was one of the Empire’s own heliopters, and for a second Edric’s entire sky was obscured by its metal-plated hull. He heard a bitter shearing sound as several of his men met the rotors, and then the machine was trying sluggishly for height, spilling out grenades in a non-stop cascade.

He tried to locate the Dragonfly, saw the man again spearing towards him. Edric shot a blast of his sting, but his adversary flitted out of the way. The bulk of the heliopter was still clawing for height, and he dropped beneath it to give himself space to think and manoeuvre.

But the Dragonfly was veering off suddenly, and Edric looked about to see what he was avoiding.

It was a Tarkesh orthopter with red flames blazing from its cockpit. The heliopter shuddered in the air as it tried to correct its course, but the orthopter, even as its wing cables were snapping, shifted its aim lazily and struck against the bigger machine’s side, staving it in. A second later and one or the other had exploded, and then they both had, and Edric was hurled head over heels through the air and across the city.

Feeling a wave of hot air roll over him, Salma caught himself in the air, still seeking out his target. There he was, blown almost up against the wall by the force of the two dying machines. He was right at the gatehouse, amongst the wrecked artillery. Even as the colonel got to his feet on the stones of the wall, Salma was stooping down on him.

Barely in time, Edric saw him coming and dragged his sword from its scabbard. It was a Hornet piece, big and heavy-edged, and he slashed furiously at Salma as the Dragonfly fell on him, but Salma was a natural in the air, pitching aside to let the great blade pass him. His own lunge scored across the colonel’s side and then he had knocked the man down, and the two of them went tumbling end over end towards the broken edge of the wall. Edric was now on top and with one hand to his side he straightened up, raising his sword to split Salma’s skull. At the same time, Salma stabbed upwards, his blade punching through his opponent’s light armour and up to the hilt beneath the man’s ribs. The Wasp colonel’s sword fell from his hand, spinning through the air until it struck the ground far below. A moment later, Salma sent the man’s body heading in the same direction.
