Troist questioned Nish in detail about his father. No one could be too careful, for the enemy had been surprisingly successful at recruiting spies and impostors. Finally he seemed satisfied, whereupon Yara began, for she had travelled to Tiksi a good few years ago. Nish must have answered to her satisfaction, for she made a sign to her husband, to which Troist nodded. He glanced across to where the twins were curled up together on the small bed asleep.

'Well, Cryl-Nish,' said Troist, 'your tale astounds me, and that doesn't happen often. It was a happy day when you ran into our daughters on the road, and I will never forget your service.'

'Thank you, surr. If I may, I will tell you the rest of it, for I'm deathly tired and my head still throbs from the blows I took.'

'Does it?' said Yara, coming up close with her candle. She checked his skull with long cool fingers, turned his head from side to side and looked into his eyes. 'I don't think there's any damage, apart from a minor concussion. I'll mix a potion for you.'

While she was busy, Nish told Troist about the amplimet, what he knew of Tiaan's geomantic abilities, and all she had done at Tirthrax.

'There has been rumour of an enormous fleet of craft, that resemble clankers, coming over the mountains from the west,' said Troist. 'No doubt our leaders have the scrutator's despatches, though no news has come down to me. But of course I am only a junior officer.'

'Though a brilliant one,' said Yara, handing Nish a mug. 'Drink this.'

Troist bowed in her direction. 'Yara is the genius of the family,' he said. 'She will be Advocate-General one day. I am merely diligent and hard-working.'

'Pfft!' said Yara, attending Nish's leg. 'You will be commander of all our forces before the children are grown.'

'I would like to be,' said Troist. 'I make no secret of that. But neither hard work nor good connections are enough. One must also have the good fortune to be where it matters, and the ability to seize the opportunity when it comes.'

'And win it!' said Yara.

'Perhaps we can help each other,' said Nish.

'Perhaps,' Troist said in a non-committal way. 'What is it you want, Cryl-Nish?'

'Since I lack the means to go home, I must do my best for the war, and for myself, here. As you know, I am an artificer by trade and have seen combat with the enemy. And with my knowledge of the Aachim constructs, I may be able to help plan to defeat them, should it come to war.' That was a faint hope, since he had seen them only at a distance, but it was the one advantage he had.

'Indeed,' said Troist, who seemed to be thinking fast. 'And what can I do for you?'

'Take me on as your adjutant.'

'Only the commander has an adjutant,' said Troist, looking to Yara as if seeking her advice. She was a cool, reserved woman except with her family. It would be hard to fool her. But Yara nodded, almost imperceptibly.

'Tactical a.s.sistant, then. Call it what you will. I would like to make my career in the army, by your side. Can this be done?'

'I don't see why not,' said Troist. 'You are well spoken, well connected, and you have valuable experience. I will see about it as soon as we rejoin my unit. That, unfortunately, could be more difficult than you might think.'

'Why is that, surr?' asked Nish.

'The defeated army has been scattered. I hope enough have survived to make a small fighting force, but first I must find them. I am leaving in the morning. You may come with me.'

They slipped out of town the following morning, heading east. Nish had expected it would just be himself and Troist, but the family accompanied him, along with five soldiers discovered among the refugees. They were all mounted. Nish had no idea where the horses came from but it spoke considerably of Troist that he had been able to obtain them in such chaos.

Troist was busy all day, despatching his troops one way or another, conferring with new soldiers who appeared out of the dust, some mounted, armed and ready for war, others footsore, worn out and weaponless. Nish tried to keep up but it was a long time since he had sat on a horse and his head still throbbed. Finally, catching him deathly pale and swaying in the saddle, Troist said curtly, 'Your place is back at the camp. I'll see you tonight.'

It was not a reprimand, though it felt like one. Nonetheless, Nish was glad to return. The camp was hidden in a scrubby gully scarcely visible from a distance. Three soldiers stood guard. Yara was working in an infirmary tent which already had half a dozen casualties in it, and more coming in all the time. Meriwen and Liliwen cleaned wounds and applied bandages. Clearly it was not the first time they had done it. Everything looked efficient and well-organised, though there was much worried talk about their lack of supplies and weapons. Nish lay in a corner, closed his eyes and fell asleep.

He was woken by someone roaring out orders like a drill sergeant. A soldier was directing the laying out of the camp, which now comprised almost a hundred troops.

As it grew dark a squad of a hundred and fifty marched in, followed by smaller groups and a mounted troop. There was no sign of Troist but as the mess tent began serving dinner Nish heard an unmistakable squeak and rattle.

His professional interest aroused, he limped to the edge of the firelight. Four clankers appeared, one after another, their eight mechanical legs moving in rhythmic pairs. They were a different design from the ones he was familiar with, lower and broader, with the overlapping armour plates shaped like leaves rather than oval shields. The shooter's platform on top contained seats for two shooters: one to load and fire the catapult, the other for the javelard that could fire its heavy spears right through the armoured body of a lyrinx.

Troist came galloping in, close to midnight. Sliding off his horse he gave it an affectionate pat, greeted his wife and daughters and immediately went to the command area, a patch of stony ground covered by a canvas slung on long ropes from tree branches. Nish was called in as well.

The tent was crowded. A small map was spread out on a folding table. 'We are here,' Troist said, indicating a spot on the map about six leagues south-east of Nilkerrand. 'We'll break camp at dawn and head south-east, across the plains of Almadin in the direction of the Worm Wood. That's an enormous forest,' he said to Nish, circling it on the map. 'Quite the largest in eastern Lauralin. Our next camp will be here,' he stabbed at a location with his forefinger, 'or failing that, here. I hope we can find more soldiers on the way. If General Boryl escaped '

'He did not, surr,' said a bald man with a bandage around his bare chest. 'I'm his adjutant. I saw him fall.'

'Slain?' asked Troist.

'The blood would have filled a bucket. His head was practically severed '

'Later!' Troist glanced at his wide-eyed children. 'What of the other officers?'

'Most are dead, surr. The enemy broke into the command tent and slew them in a minute. Had not I been outside they would have killed me too. You are the most senior officer alive, surr. If you can't rally the troops, I fear all Almadin will be lost.'

'I thought as much,' Troist said heavily. 'Well, there's not much I can do with a few hundred troops and a handful of clankers, but whatever can be done, I'll do it.'

He turned away, and Nish, standing at his elbow, caught a strange gleam in the man's eyes. Troist's chance had come. Should he be able to seize it, it would be the making of him. If he failed, none of them would survive.

Almadin was a largely treeless land, flat apart from residual mounds topped in black rock, the tells of towns abandoned in ages past. The soil was barren, salt-crusted, and supported only yellow gra.s.s. Here and there were round saltpans, quite bare of life. Carrion birds circled in the distance.

They wound back and forth across the arid land for days. Troist spent all the daylight hours in the saddle, combing the countryside for survivors of the battle and sending them back to the camp. All the troops he could spare were doing the same. The trickle of battered, dispirited soldiers became a flood.

More clankers began to come in. Many had been lost in the battle, for as soon as the officers had been slain the enemy turned the attack to the clankers' shooters, exposed on their platforms atop the machines. Once the shooter was dead a clanker operator could do nothing but flee. Some machines had only an operator, others as many soldiers as could fit inside and cling to the sides and top.

Troist greeted each one, no matter what time they arrived, and ensured they were fed, given a place to sleep and had their wounds attended. Nothing was too much trouble. He scarcely seemed to sleep at all.

On the fifth night he took a detachment out on a raid, on horseback and in half a dozen clankers fitted with the new sound-cloaker that reduced their rattling squeal to a whisper. Nish was not invited to go with them and knew nothing of their objective. Yara, who did but would not say, paced the whole night. Her worry infected Nish. If Troist and his bold team did not return the little army would fall apart.

Dawn came and there was no sign of them. Noon went by. Yara was still pacing, rigidly now. The sun went down, and finally a dust cloud appeared on the horizon.

'It's Troist!' cried Yara, her reserve failing for an instant. Tears glistened on her eyelids.

In they came, weary and brown with dust but grinning broadly. The clankers were packed with swords, crossbows, camp implements, tents, provisions and other gear abandoned by the defeated army. Hastily constructed wooden sleds, piled high, were towed behind.

'This should solve the supply problem for a while,' said Troist. 'You could not call it a victory, since we were unopposed. We're still running from the enemy but not as fast as before.'

'Where are the enemy?' Nish asked.

'We saw them in the air above Nilkerrand, and doubtless some still occupy what remains of the city, but most, I am told, went back across the sea to Meldorin.'

'So the attack on Nilkerrand was a raid, not an invasion?'

'A raid and forerunner to the invasion.'

'When will that occur?'

'If I knew that, Cryl-Nish, I wouldn't be wasting time listening to your inane questions.' He turned to his wife. 'Now that things are more secure, I'd like you and the children to go back to Kundizand.'

'No, Daddy!' cried Liliwen. 'Don't send us away again, please.'

Meriwen, normally conservative and responsible, supported her. 'We wouldn't feel safe without you, Daddy. And if you get hurt, you'll need us to look after you.'

'I'm not going to argue ' he began, but Yara laid a hand on his.

'Just a few more days,' she said. 'The enemy can fly across the sea to Kundizand in hours. We're safer here.'

'Oh, all right, but as soon as the chance comes ...'

'Of course,' she said.

The army slowly swelled as they travelled. Troist had begun to form it into fighting units, and as the news got around, soldiers appeared from everywhere. After ten days they had a force numbering three thousand, several hundred of them mounted, as well as a fleet of seventy-one clankers. Five more machines needed repairs before they could go into battle, and Nish worked long days helping the other artificers get them ready. He learned more about his trade in that short period than he had in his years at the manufactory. Many more clankers lay abandoned at the battlefield east of Nilkerrand, or in flight, but until operators could be found or trained, they were useless. Troist had done a wonderful job so far, though he was worried that the scrutators would not let him keep his command.

In the evenings Nish sat with Troist and another tactician, telling them all he knew, or had deduced, about constructs. Together they began to formulate tactics to attack the machines, tactics for defence, and plans for all kinds of contingencies. They worked until after midnight every night, each taking one side or the other and fighting imaginary battles in a variety of terrain.

This night, the twelfth since leaving the inn, Troist tossed his lead pieces aside before the midnight bell had struck. He rubbed red eyes, yawning.

'Games are all very well but they count for naught when the battle starts. Out there, we can't see what's going on after the first few minutes. Our messengers are slain, or the field simply changes so quickly that our orders are useless.'

'They don't make the kinds of mistakes we do in battle,' said the other officer, Lunny. 'It's as if the enemy can communicate with each other.'

'What if we were to send up an observer in a balloon?' said Nish. 'He could see the whole battle and signal us what was really going on.'

'Until the wind blew it away,' said Troist, 'or a flying lyrinx tore it open, which they would do at once.'

A messenger ran in, saluted and handed Troist a folded piece of paper. Troist read it, frowned and stood up.

'We will find out soon enough, gentlemen. A sizeable force of lyrinx are moving in our direction; many hundreds. We must prepare to do battle in the morning.'

He looked every inch a commander, though as his eyes rested on Yara, who sat up the back winding bandages, Troist stiffened. Tomorrow could see the brutal end of his family, but it was too late to send them to safety. Why hadn't he taken the chance while he had it?

PART THREE.

DIPLOMAT.

TWENTY-SEVEN.

Irisis woke with terrible roars and cries ringing in her ears. She felt her throbbing forehead, which sported a lump the size of a small potato. Lights, surrounded by haloes, danced along the corridor. They seemed to be moving closer. She rubbed her eyes, trying to see what they were, but they only separated into paired images.

She supported herself on the rock wall, struggling to recall what had happened. She had been on the eighth level of the mine. A lyrinx had come after her and Ullii had fled.

'Who ... are you?' Irisis said to the first pair of lights.

The scrutator chuckled. 'How quickly they forget.' Bending down, he whispered, 'It's your lover, Xervish Flydd, come to rescue you.'

'How did you know ?'

'Peate turned up with a story about you going off with Ullii into the forbidden section, so I came to find out why. We had just about given you up when Ullii hurtled out from a tunnel that isn't even on the map, crying for us to save you from the clawers. So here we are.'

'How did you manage it?'

'Mancer's secrets, crafter. Mancer's secrets.'

Taking her arm, he helped her to the lift, which was not far at all. Within the hour, Irisis was tucked up in bed with a cool compress across her forehead and a steaming bowl of willow-bark tea on the bedside table.

The scrutator took the map, which was still crumpled in her hand, and unfolded it. 'The seeker said something about good crystal. A big big crystal.' crystal.'

'I've marked it on the map, with a red circle.'

'Here?' He held the map out.

'That's where Ullii sensed it, but down at an angle. Like this!' She mimicked the gesture. 'The ninth or tenth level.'

He frowned. 'It had better not be lower than the ninth. We'll get started in the morning.'

That being miner's work, Irisis went back to her own, directing the twenty artisans and fifty prentices in the making of clanker controllers. Once a day Ullii was taken down to check that the miners were driving in the right direction. Irisis sometimes accompanied her. Working on the eighth level was perilous and slow. The miners were guarded by squads of soldiers with heavy crossbows, but they saw no further sign of the lyrinx.

They reached the ninth level, which was dry here, but found no crystal. Ullii still pointed in the same direction so they continued sinking the shaft towards the tenth. Water began to trickle into the workings and they had to bring in a pump, powered by two workers on a treadmill, to keep them dry. Below the tenth, the trickle would become an unstoppable flood.

A couple of weeks after Ullii's discovery of the crystal, Irisis woke to the familiar crash of a catapult ball against the wall of the manufactory. She was running to her station, up on the wall near the front gate, when the scrutator caught her by the arm.

'What is it?' she yelled, for already the racket was deafening.

'Take no risks!'

'I have to get to my post!' She tried to pull away but he did not let go.

'I mean it, Irisis. I can't replace you.'

'Plenty of women are prepared to warm the scrutator's bed!' she snapped, deliberately mistaking his meaning.

'Don't be a fool, crafter. I need you: to make controllers, to support Ullii and, most of all, to work with me on the node problem.' Nodding curtly, he let her go.

Irisis ran up the stairs, feeling guilty that she had not done better, but she could not make controllers without crystal. On the wall, crossbow in her hands, she soon forgot the scrutator's warning. In the light of the watch flares Irisis could see eight lyrinx, and from the clamour on the far walls, there must be just as many on that side.
