Tetrarch

They made their way up the slope, Malien's weight heavy on Tiaan's shoulder. The flying lyrinx began to circle around them. Tiaan stopped abruptly.

'What is it?' Malien asked.

'I know her.' Tiaan was staring at the transparent-skinned creature. 'Her name is Liett. She was one of the lyrinx at Kalissin; a flesh-former.' That roused unpleasant memories.

'What will she do?'

'I have no idea,' Tiaan said. 'I spent three months as their prisoner, but I knew little more about them at the end. Though…'

'Yes?'

'They are deadly in battle, but when you get to know them… I found them to be honourable creatures.'

'That's encouraging,' said Malien, 'yet I can't say I want to get to know them.'

They watched the circling lyrinx, which now turned and flapped towards the two fallen ones. 'She's given up.'

'They know where we are. They can come back at any time, with an army.'

The lyrinx did not attack again, though as Tiaan and Malien made the weary climb up the mountain, Tiaan twice saw Liett circling high above. After they passed into Tirthrax, Liett flew east.

'What do we do now?' Tiaan asked as they rested in the entrance.

Malien unwrapped a food packet. 'Have some filuvior.'

Tiaan took a chunk of something that looked like green, crumbly cheese but dissolved smoothly in the mouth. It had a taste she could not put words to, a combination of aromatic, creamy and acrid. Her mouth tingled afterwards but she did feel better.

'What is this stuff, Malien?'

'A tonic for exhaustion, body or mind.'

She took another piece. Tiaan did too.

'This level of the city is undefendable,' Malien went on. 'And that's a pity, because there are things here I would sooner the enemy never saw, not least of them the wrecked constructs. Fortunately I can seal off the upper and lower entrances. We have greater treasures there. I wonder what brought the lyrinx here?' She looked questioningly at Tiaan.

'The amplimet, I expect. They can track such things.'

'How do you know that?' Malien said sharply.

'At the manufactory, when I was an artisan…' Memories of her lost life came rushing back and for a moment Tiaan could not speak. 'The enemy were locating our clankers from afar, and we could not tell how. I discovered that they could sense the aura given off by a working crystal.'

'How? I've never heard of such a thing.'

'I was never sure. They used something that resembled a large, leathery mushroom. I don't know whether they made it, grew it or -'

'Flesh-formed it,' Malien said, with an uncharacteristic shiver. 'Go on.'

'I developed a way of shielding crystals from them.'

'What did you do?'

'I wrapped the crystals in gold foil, sealed them tight and covered everything with pitch. That cut off the aura and prevented the crystals being sabotaged by heat, too.' She looked away. 'I miss my work.'

'What a remarkable young woman you are,' said Malien. 'I wish -'

'What?'

'No matter.'

Malien activated sentinels – squat black cones – at the entrances to the lower and upper levels. Tiaan's eyes lingered on the broken constructs as they went by. The design, and the workmanship, was magnificent. Were they powered by the field, as clankers were, or did they draw on an entirely different source? She wanted to get inside one and find out. Tiaan really missed her craft.

They went up. It was not far, now that Tiaan knew the way, but they had to climb eight long swirling flights of stairs, one after another. By the last, the old woman was shaking.

'This day has been rather too much for me. I'll see you in the morning.' Malien went into her room and closed the door.

Tiaan had a drink of water and sat down until her heart stopped hammering. She was overcome by a deep melancholy. Such a small decision to care about Minis, such mighty consequences. Was the world already at war with the Aachim? Were innocent people being slaughtered while she sat here in luxury?

Tiaan sprang out of the chair. She felt a mad urge to hurt herself, to make herself suffer as a way of connecting with Haani. Flinging the door open, she hurtled up the stairs to Malien's lookout, rejoicing in the ache in her side. She slapped the opener with her palm. The glass wall slid back and Tiaan pushed out into the gale.

The balcony was icy. Tiaan slipped, cracking her shin against the stone seat. Limping to the edge, she looked over. The air was perfectly clear, the distant peaks like etchings on glass. A low sun glinted bronze off the ice sheet.

The view was magical but Tiaan could not see it, any more than Malien did in the hours she spent here every day. Malien looked across the void to Aachan, the ancestral world her people had been cut off from thousands of years ago. Now they would never return. The small, cold globe that was Aachan was no longer habitable. They were forever exiles.

As was she. By the time the red sun plunged into a lake of mist, Tiaan was practically frozen to the seat. 'What the blazes do you think you're doing?'

Malien was shaking her. Tiaan could see nothing, and for an instant of horror thought her eyes must have frozen solid. The Aachim picked crusted snow off her eyelids, rubbed them with a warm palm and Tiaan's eyes cracked open.

Back down below, her fingers wrapped around a mug of a custardy-thick, sweet red drink, Tiaan began to feel rather foolish. The emotions that had taken her outside felt alien now.

'I suppose…' she said haltingly, 'I was punishing myself.'

'What a stupid thing to do! If you have done harm, do something to make up for it.'

Tiaan sipped her drink. Malien was right. She must do something, but what? Maybe she should try to get back to the manufactory and resume her artisan's work.

Malien was turning the pages of a small book bound in yellow calf, though not reading it.

'Is something the matter?' said Tiaan.

Malien laid the book to one side. 'I cannot tell you what a shock it was to hear of the gate, and see those constructs. Arrogance was ever an Aachim failing, and so many constructs, and such power, would breed hubris in the meekest of breasts. Vithis is a type I know well – a brilliant, blind fool. After the loss of world and clan, he will not compromise. He has suffered – why should others not suffer equally? We have had many such leaders in our Histories, but all looked backwards to a time when we were great, while knowing that such times were past.

'Vithis is different. Having lost everything that mattered, nothing can moderate him, and now he has the opportunity of a lifetime. With his mighty force, the most powerful ever assembled, he comes to a world ruined by war. What will he do?'

'Take it,' Tiaan said softly. 'But… we are all humankind. Maybe he will ally with us to defeat the lyrinx.'

'I would,' said Malien, 'but why would Vithis? Many Aachim think of you old humans as primitive, even sub-human, and from what you say of him Vithis holds to that view. He may prefer to let the lyrinx win, or even side with them to destroy humanity.'

Tiaan's blood congealed. 'He would not,' she whispered. 'He could not.'

'Look at your own Histories, Tiaan. The more advanced races, or the more powerful nations, have wiped out hundreds of the lesser.'

'But humanity has a great and ancient civilisation. How could anyone think…?'

'Look to your Histories, I say.'

Tiaan could not countenance it. That Vithis might destroy humanity, and all its culture and Histories, as carelessly as one might kill a cockroach, was incomprehensible.

'And nothing can be done about it?' she said in a daze.

'I wouldn't say nothing,' said Malien. 'Vithis must have weaknesses as well as strengths.'

'I saw none, apart from clan rivalry.'

'Which would disappear the instant the Aachim were threatened.'

'And perhaps your own people would join with them to make an even stronger force.'

'If pushed hard enough, they probably would.'

'But not you, Malien?'

'I will never betray my own kind, Tiaan. But I will do what I can for all humanity.'
