Nixx sat at the table, staring at his tally sheet. His broad fingers were stained with ink. He seemed not to know what to do. The other servants stood by the door, equally bewildered and fearful. Tiaan could read their faces. Without Gilhaelith, they had nothing. He had always been here some families had served him for five generations. Now he was gone and Nyriandiol was unprotected.

The crystal rod lay on the table. It was an elongated prism, translucent and heavy, capped at one end with shiny steel, a basket of which enclosed the striated sides. An ironstone rosette was fixed on the open end. Gilhaelith's teaching had barely touched on such devices, though she knew it could be a weapon in the right hands.

She slipped it into her pocket. 'What are you going to do, Nixx?'

'I can't do anything!' he wailed, still wringing his fleshy hands. 'Four lyrinx might have carried him halfway across the continent.'

Tiaan was back on the terrace, numbly watching the fog wreathe through the vines, when she heard raised voices at the front door.

'The master is lost,' said someone she did not know. 'We will never see him again. Let us take what we can carry and go.'

'He may come back.' Nixx's voice rose above the others. 'We must maintain Nyriandiol for his return '

'You old fool!' spat Gurteys. 'It's finished. This place will be plundered within days. We've lost everything.'

'We cannot betray our master.'

'We can't hold the place against lyrinx or anyone else. Come on!' she yelled.

'Don't,' he quavered. 'Let me go. Aaah!'

Tiaan knew what was going to happen. s.n.a.t.c.hing her water bottle, she crabbed sideways toward the path, watching the front door. Shadows moved inside. She sought for a strong part of the field; as powerful as she could bear.

'There she is.' The squat woman, Alie, wielded a kitchen cleaver over her head.

'Don't kill her,' shouted Gurteys. 'She's worth ten thousand gold ones. Knock the metal crab down and break it.'

She ran around the outside of the terrace and stood waiting for Tiaan, holding a wicked two-headed axe. Tiaan stopped. A host of servants were coming up behind, and Fley was running across to join his wife. There was no way past.

But Fley caught Gurteys by the arm, swinging her around. Run Run! he mimed, and as Gurteys swung the flat of the axe at his head, Tiaan slipped through. Fley went down and was trampled as a dozen women stampeded by, brandishing makeshift weapons.

Where were the guards? Perhaps they were already down below, looting. She hoped so, for her sake. Tiaan pulled power into the controller and fled into the fog, moving the four legs by instinct.

She looked back. Any competent archer could have shot her with a crossbow, but fortunately these were mere household servants. Or maybe those who wanted the reward had prevailed. A stick whirled through the air, just missing her. A rain of rocks followed, one whizzing over her shoulder, another striking her back brace so hard that it cracked. Pain jagged up her side.

Realising that she still had Gilhaelith's crystal rod, Tiaan fumbled it out. Just how did one use it? She recalled the lesson about using crystals as weapons, though she'd not had the chance to practise with one. She pointed the crystal at the ground, depressing a strip of metal anch.o.r.ed at one end. A yellow ray burst from the open face of the ironstone rosette. She swung it at the feet of her pursuers. Rocks exploded, flinging gravel everywhere. The servants threw themselves out of the way.

Skilled at operating the walker now, Tiaan fleeted along at running speed until she ran into a wall of fog. She dared another glance over her shoulder. The mob was out of sight, yet she could hear it coming. If she went slowly they might not hear her. The small rubber feet made little noise.

They followed for an hour, after which she heard no more. Perhaps the tireless walker had outdistanced them, or they had given up. That hardly seemed likely: they had much to gain and nothing to lose. She kept going. Later the fog thinned enough for her to see back for half a league. The rim of the crater was empty. She saw no one on the sides, either. Tiaan supposed that they had gone back to wait her out. They knew she couldn't get away.

The bare mountaintop was no place to spend the night. Big cats hunted up here, and other predators. Going carefully down the outer slope, she took refuge in one of the lava tubes that threaded the side of the mountain. From here she could see the rim. No one came after her. Her water bottle was empty and there was no water here. Below, the slope was too steep for the walker so she had no choice. Tiaan climbed back to the rim, clutching the rod. Nyriandiol was a dark shape against the horizon. Not a single light showed, which was strange.

She had to have water and the villa was the only place she could get any. It took hours, feeling her way forward in the dark, afraid she would go over the edge without realising it. Finally she was close enough to see the peaked roof. Still no lights. It had to be a trap.

Then she smelled the blood. Had the burst from her crystal killed someone? The stars gave too little light to see. She continued until one foot of the walker struck something yielding. It was the size and shape of a person.

'h.e.l.lo?' she whispered.

No reply.

She went around it. Near the paved yard she again smelled blood. Holding the crystal out at a shallow angle, she pressed the metal strip and swept the beam across and back, just for a second. Gurteys lay dead, her neck broken, a bag of gold and silverware clutched to her chest. Fley was nearby, his fingers crooked towards her in death as in life. By the front door, a lyrinx lay with its head severed from its body. Oddly, it smelled of tar.

Tiaan stood by the bodies, listening in case there were more lyrinx. She heard no sound. Creeping inside, she was going carefully down the hall when someone cried hoa.r.s.ely, 'Who's there?'

'Nixx?' she whispered. She could see more bodies further along.

'Tiaan?'

She turned into the dark salon. Nixx cowered under a desk. She helped him out. Blood streaked his forehead and left thigh. 'What's happened, Nixx?'

'A lyrinx came looking for you. We managed to kill it but it did a lot of us first. The rest took what they could carry and fled. I can't say I blame them.'

She lit the lamp by the door. 'And you?'

'I am loyal to my master, but what am I to do? I know I'll never see Gilhaelith again. I must run and try to find a new living. It won't be easy, at my age.'

She felt for him her situation was much the same. All she could do was try to complete the repairs and go ... where? Borgistry was nearest. She must give the thapter to Scrutator Klarm and throw herself on his mercy a commodity the scrutators had in short supply at the best of times. Little hope there, but she could not survive on her own.

'Please stay,' she said, 'just until I fix the thapter. It's nearly done.'

'I cannot stay.'

'I beg you Gilhaelith would expect it. I can't do it alone.'

He agreed, though with an ill grace, and she began.

Why had the lyrinx come back for her? When it did not return, others would follow. And the biggest unanswered question of all what had Gilhaelith discovered about broken backs? Was that why he had gone to that secret meeting?

If only she knew where they had taken him ...

Tiaan laboured night and day on the thapter. Four days later it was done, though she still had to test it. And even if it worked, what if the amplimet would not take her where she wanted to go?

She was working up behind the binnacle when a faintly bituminous odour reminded her of something. As Gilhaelith had been taken, and again near the dead lyrinx, she had smelled tar. Going to the front terrace, she checked the body of the beast. Its great feet were deeply stained with tar. She hurtled the walker inside. 'Nixx, Nixx?'

She found him in Gilhaelith's offices, packing coin into a leather bag. 'Nixx,' she cried. 'I've just thought of something.'

'What?' He did not look up.

She told him about the tar. He went out to examine the corpse for himself. 'Looks like it's been walking in tar for years the stuff is right into the pores of its skin.'

'Where could it have come from?' she asked.

'Only one location I can think of. Snizort.'

'Snizort?'

'A place south of here, famous for its tar pits. It's in the land of Taltid.' He indicated it on a map. 'I'll go through his ledgers and see what I can discover.'

He came down shortly afterwards, finger holding a ledger open. 'Gilhaelith purchased several kinds of bituminous spirits from Snizort. He's made some notes on the place.'

She read them, though they mainly had to do with geography. An arid land, spa.r.s.ely vegetated, with tar pits and seeps all over the place.

'Oh well,' she said, feigning disinterest. 'He's lost. I'd better keep going. Could you keep watch for me?'

'No. I've done more than my duty, and I can't stay a moment longer.'

'Just for an hour. I'm nearly finished. Please.'

'Oh, very well, for my master's sake. Half an hour only.'

Nixx came running in ten minutes later, his jaw working like a nutcracker. 'Constructs, marm. Lots of them.'

She dropped her wrench, which just missed a fragile gla.s.s mechanism. Tiaan reached over to pick it up. 'How many is lots?' she asked, trying to keep her voice steady.

'At least fifty.'

'Where are they?'

'Approaching the foot of the mountain.'

Fear tickled her throat. 'How long will they take to get here?'

'Couple of hours; no more.'

It was not enough; the tests weren't finished. 'You'll have to stall them, Nixx.'

'Can't do it, marm. They'll torture my family if I try. You can't ask that of me.'

'What are you going to do?'

'Run, as fast as I can.'

'Where to?'

'We have a hiding place.' He hesitated. 'An overgrown lava tunnel, way down in the forest.'

'How can I get the thapter out of here?' She should have asked that question a long time ago.

'You can't. We had to remove the window to bring it in.' He was looking increasingly jumpy.

'All right,' she said. 'Go. Save yourself. And thank you, Nixx.'

Offering her a sketchy salute, he ran up the steps. She skittered the walker across to the door and barred it, then raced back to the thapter. There was no time to replace the metal skin sections. She strapped them to the back and got on with the testing. If it did not work the first time, she was finished.

Tiaan was still doing the tests when she heard the echoing whine of constructs coming up the road. Only minutes left. She strapped her walker to the side of the thapter. Pulling herself into its seat, she pa.s.sed a strap around her, took hold of the trumpet-shaped lever, visualised the field and let the energy flow.

Nothing happened. She tried again with the same result. Had she forgotten something? Yes, the hedron was still in its socket in the walker, and the thapter needed it and the ampliment, to fly. As she climbed out to get it, the Aachim began to smash down the front door.

FORTY-NINE.

Nish felt an overwhelming urge to run, but there was nowhere to run to. The hors.e.m.e.n were already melting into the forest. There was just the clearing, Vithis and himself.

'Get down,' said Vithis. 'Send your stolen horse away. You will not be needing it again.'

Nish did so. The horse trotted off.

'Come here.' Vithis leapt to the ground.

Nish came to within an arm's reach of the intimidatingly tall Aachim, who held up his palm. He carried no cane now and the limp was gone. He seemed calmer than before.

'After your previous behaviour, you dared return to my lands?'

'These are not your lands. You're an invader.'

'Force makes them mine,' said Vithis, standing close and looking down on Nish. 'No one has dared oppose me.'

Nish was used to intimidation; his father had done that to him all his life. He had developed a technique to deal with it he imagined his father failing at what he most wanted. So, what did Vithis most desire, and fear he would never get? A homeland for his people? It gave Nish strength. 'We will will dare, should it be necessary! But we know Aachim to be human too.' dare, should it be necessary! But we know Aachim to be human too.'

'I would not have thought it from the way you behaved the other day, Marshal Hlar.'

'I am no marshal,' said Nish.

'Indeed! Your speech revealed you to be a most common common man.' man.'

'I merely reflected your own character back at you,' Nish said coldly. 'If you do not like what you hear, look into your own soul.' He was risking his life, but every word the man said was a wrongness and a goad.

Vithis seemed to grow even taller. 'I could tear you apart with my naked hands.' He held them out and the impossibly long, curving fingers could have spanned Nish's throat.

'It would only carve the bitterness deeper into your heart.'

Vithis whirled and stalked away. Why had he come? Nish had nothing of any use to him. Or was he just looking out for Minis? There were other Aachim in the thapter, and someone behind the javelard in the turret at the back, but it was pointed at the ground. This was between Vithis and him.

'Why do you seek to corrupt my foster-son?' said the Aachim from some distance.

How much did Vithis know? Maybe everything. Nish saw no point in lying, though he was not necessarily going to tell the whole truth either. 'Minis sought me out,' said Nish. 'We talked. I liked him and we both wanted the same thing.' sought me out,' said Nish. 'We talked. I liked him and we both wanted the same thing.'

'And that was?' Vithis said dangerously.

'To prevent a new war, and end this one that has been going on for generations.'

'We care nothing for your war.'
