The land before them dipped in a great shallow bowl leagues across. At its bottom was the sword-blade glitter of a large river, lightning-bright in the sun. All around were broken and rolling hills, green or gold with crops or dotted with grazing herds. They stretched to every horizon, gilded by the sunshine and ruffled to glimmering waves by the northern breeze.

As the expanse rose up to meet the blue shadows of the mountains in the north, so the watchers saw a wider hill there. It was a city, white-walled and towered, the smoke of its hearths rising to haze the cerulean arch of the cloudless sky. Everywhere amid the clotted disorder of its streets minarets and cupolas caught the sun, and at the height of the hill gleamed the massive dome of the Temple of Ahrimuz, the biggest in the world after its older rival in Nalbeni.

There were palaces there, in the shadow of the temple. The women could see parks amid the city, the ripple of water in tended gardens. And even at this distance they could hear the chanters in the towers calling the faithful to prayer. Their oddly harmonious wails drifted down the wind, and the Merduk escort bowed their heads for a moment in acknowledgement.

“Where are we? What is this place?” one of the women demanded in a panic-shrill whisper.

But one of the escort had heard her. He bent from his horse into the waggon and gripped the woman’s jaw with one brown hand.

“We are home,” he said distinctly. This is Orkhan, home for me and you. This is the city of Ostrabar. Hor-la Kadhar, Ahrimuzim-al kohla ab imuzir . . .” He trailed off into his own language as if he were reciting something, then turned to the women in the waggon again.

“You go to Sultan’s bed!” And he laughed uproariously before touching spurs to his horse’s belly and cantering off.

“Lord God in heaven!” someone murmured. Others began sobbing quietly. Heria bent her head until her filthy hair covered her face.

Can you remember him? How he was when he had that devil-may-care grin on his face, his eyes alight? Can you remember?

A long summer’s day, the sun hanging in a cobalt sky and the Thurians mere guesses of shadow at the edge of the world. They were in the hills above the city, watching the huge length of Aekir sprawl out along the shining length of the Ostian river. Far enough to view the whole of the city walls but near enough to hear the bells of Carcasson tolling the hour, the sound drifting up into the hills along with a faint rush of noise; the echo of a distant throng.

Wine they had had, and white bread from the city bakeries. Apples from last year’s crop, wrinkled but still sweet and moist. If they looked out to the south, beyond the city, they could see where the Ostian river widened in its estuary before opening out into the Kardian Sea. Sometimes when the wind was from the south, the gulls wheeled and cried in the very streets of the city itself and the salt tang was in the air so that Aekir might have been a harbour city on the rim of an ocean. Heria had always loved to come into the hills and see the Kardian glittering on the horizon. It was like seeing the promise of tomorrow, a doorway into a wider world. She had often wondered what it would be like to have a ship, to ply the sea routes of the wide world, sleep beneath a wooden deck and hear the waves lapping at her ear.

Corfe had laughed at her fantasies, but never tired of hearing them. He had been wearing his ensign’s uniform that day—Torunnan black edged with scarlet. Blood and bruises, they called it. His sabre had lain scabbarded at his side.

She could not remember what they had said, only that they had been content. It seemed to her now that they had never thought how lucky they might be to have each other, the sun flooding down on the grass-covered hillside, Aekir spread out on the earth below them like a brilliantly coloured cloak let slip upon the world and the sea glimmering at the limit of vision, full of possibilities. Everything had been possible; though even then, in that last, glorious summer, the Merduk host had already been on the move. Their fates had been fixed, and their snatched seconds were trickling away like sand in an hourglass.

The train of booty and prizes lurched and trundled downhill towards Orkhan, capital of the Northern Merduks, whilst in the waggons the women sat stark and silent and the Merduk horsemen sang their songs of victory all around.

T HE rain had held off and a weak sun was pouring down over the blasted expanse of the land. Corfe helped the old man up the muddy slope, using his sabre as a staff. Ribeiro came behind them, his face swathed in filthy rags, one eye invisible with the awful swelling.

They reached the top of the hill and stood panting. Macrobius leaned on Corfe with his head bent, his bony chest sucking in and out. Corfe looked down the western slope and suddenly went very still. Macrobius tensed at once, his liver-spotted fingers gripping Corfe’s arm.

“What is it? What do you see?”

“We’re there, old man, there at last. Ormann Dyke.”

The land levelled out west of where they stood. It dipped down into a broad valley in which the wide expanse of the Searil river foamed and churned, full after the recent rains. There was a bridge there, spanning the current. On the western bank it was constructed of weatherbeaten stone, but here on the eastern side the supports were of fresh timber.

On the eastern side of the Searil great works of earth and stone had been thrown up, revetments and trenches and stockades. The smoke of burning slow-match drifted down the breeze along with the cooking fires, and above the fortifications the black and scarlet Torunnan flag flapped. Corfe felt a strange ache in his breast at the sight of it.

The eastern fortifications extended maybe half a mile on either side of the bridge. Corfe could see culverins gleaming with brass behind gabion-strengthened emplacements, soldiers walking up and down, a knot of cavalry here and there. But the entire rear of the position seemed choked with people. There were thousands there in the spaces behind the battlements, some obviously cooking, others sleeping in the mud and more trudging purposefully towards the river.

The bridge was clogged with them. All along its length it was jammed with handcarts, animals, people on foot and in waggons. Torunnan troopers were trying to direct the traffic. There was nothing panicked about it. It was more like a sullen retreat, as though the crowds of refugees were too exhausted to feel fear.

Corfe peered further west, across the river. The land rose there in two ridges running parallel to the Searil. The ridges themselves were steep and rocky, and their summits were dotted with watchtowers and signal stations. But there was a gap close to where the bridge arched out from the western bank, and in this gap, maybe a league wide, the fortress of Ormann Dyke proper stood.

The walls were sixty feet high and wide enough for a waggon to drive along. Every cable or so their length was interrupted by a tower which jutted up to a hundred feet, guns glinting in the embrasures. There were odd kinks in the layout of the walls, and the sides of the towers met at strange angles. These were recent innovations, designed to concentrate the gunfire of the defenders so that anyone approaching the dyke would be caught in a deadly crossfire.

At the southern end of the Long Walls was the citadel. It was built on a steep-sided spur that jutted out from the main line of the ridges. Its guns would dominate the whole frontage of the dyke itself.

In front of the walls, and constructed at least six centuries before them, was a vast ditch, carved out of the very bones of the land. It was forty feet deep and at least two hundred wide, a work of unimaginable labour built by the Fimbrians when Ormann Dyke had marked the limits of their empire, before the first ships sailed up the Ostian river to found the trading post that would eventually become Aekir. This ditch extended for fully three miles in front of the walls, like a second river to mirror the brown flow of the Searil. It, too, was full of muddy water, and its sides were constructed of slick, close-joined brick. Corfe knew that under the water were entanglements, impaling caltrops, and all manner of devilry designed to rip out the bottoms of any boats foolish enough to try and cross. He knew also that once there had been charges of gunpowder placed in waterproof caches along the ditch, with underground fuse tunnels connecting them to the main fortress. These had fallen into disrepair within the past few years, but he did not doubt that the dyke’s defenders had remedied that by now.
