Nish looked across the foyer after them. ‘I think Tiaan has taken leave of her senses.’
Malien came around the side. ‘She’s been troubled for a long time, and Minis’s sacrifice shook her.’
‘She’s always been a little … obsessive.’
He went out, inspecting the defences with a professional eye. Nithmak Tower occupied the centre of the flat-topped peak, leaving a rim of bare rock all around. The top of the peak was only a few hundred spans across, and thousands of fliers stood in a ring around the edges, watching silently. Nish shivered. At least they’d keep the thapters away.
He did a rough calculation. At a pinch the top might accommodate a hundred thousand lyrinx, crammed close together, but four or five times that number had to pass through the gate, if they survived the journey.
Nithmak could not be attacked from below but was vulnerable to attack from air-floaters and thapters. ‘I wonder why Vithis chose this place?’ he said to Irisis. ‘There are dozens of larger peaks in this part of the sea.’
‘Something special about its node, you can be certain.’
‘We’d better prepare to defend.’ Nish scanned the salt with Irisis’s spyglass. ‘The lyrinx are awfully spread out.’
‘And the water is coming in quickly. The salt lakes below the Trihorn are already overflowing.’
‘It’ll take days to get to the other end of the sea,’ said Nish, ‘so it’ll be quite a while before the level starts to rise.’
‘The Dry Sea isn’t like a bathtub, Nish,’ said Malien, joining them. ‘The water’s coming in faster than it can flow away. For all we know, the level could rise to the top of this peak before it even reaches the far end of the Dry Sea, three hundred leagues away. The flow could wash Nithmak away, as it collapsed the Trihorn.’
Nish began to say something, but then shook his head and hunched down, staring at the ground. He was also starting to feel panicky. The ribs he’d cracked when Vithis had tried to drag him into the Well ached and he stood up again, rubbing his side.
Malien laid a hand on his shoulder. ‘But not, I think, in the next day and night. We have time yet.’
‘Will it be enough?’ Nish focussed his spyglass upon the straggling line of lyrinx, and the squadrons of clankers that continued to harry them, where the country permitted it. The fleetest of foot were not far from the base of Nithmak now.
‘For many, though not the stragglers. Let’s go up to Tiaan.’
It proved a long climb up steep and narrow stairs. ‘I don’t see how we’re going to get half a million lyrinx up here,’ panted Nish as he rested halfway up.
‘The gate doesn’t have to open here,’ said Malien.
Tiaan was sitting on a glass chair in a room near the top of the tower. Unlike the lower sections, its walls were spiralling strips of black metal, like the metal of which constructs were made, whose spaces had been filled in with glass. The floor was made of metal crescents cunningly locked together. A table of woven wire supported a black metal cube. Tiaan’s head rested on her hands and she was staring intently at the cube.
‘Is that it?’ said Nish. ‘Or is it a last joke by Vithis?’
Tiaan turned her head and stared right through him, as if she didn’t recognise him. Nish’s scalp prickled.
‘Vithis was not a joking man,’ said Malien.
‘There’s something inside,’ said Tiaan, clutching the amplimet in both hands. ‘I can see its aura, but I don’t know how to open the cube.’
‘There’s not much time,’ said Gilhaelith, peering out through the thick glass.
Nish went over beside him. The air was heavy with flying lyrinx. ‘Is that an air-floater, way up high?’
‘If it is, it’s bigger than the air-dreadnoughts that attacked Fiz Gorgo. I wonder what it’s up to? Orgestre could finish this by dropping boulders on us.’
‘Boulders,’ sniffed Nish.
Crash! The tower gave a gentle shudder.
‘Sometimes the simplest attacks are the most effective. That didn’t miss by much.’
‘Is there anything we can do?’
‘Go up in the thapter,’ said Tiaan. ‘Keep them away. I can’t think.’
‘Come on, Nish,’ said Malien. ‘We’ve got work to do.
‘The box doesn’t open,’ said Tiaan, as Nish and Malien clattered down the stairs. ‘Why?’
‘Perhaps it’s locked,’ said Irisis.
‘Of course it is. Vithis said so. And he gave Malien the key, that sapphire rod.’ Tiaan ran to the top of the stairs, shouting, ‘Malien. The key!’
Nish came running up with it. ‘Thank you,’ Tiaan said absently, already turning away. Then she swung back. ‘Nish?’
‘Yes?’
She put out her arms. ‘Good luck.’
SEVENTY-SIX
They stopped halfway for a breather and Nish looked down through a slit in the stone. Lyrinx now clustered on every surface, wings folded. Others clung to the sides of the pinnacle and thousands more wheeled in the air. Far below, the water was flooding towards the lyrinx stragglers, still fifteen leagues away on the salt. Other lake lobes pressed towards the middle of the line, forcing the fleeing lyrinx further out into the Dry Sea. Water was pooling there in places, too.
As Nish and Malien ran through the broken door, their way was blocked by half a dozen lyrinx, Liett at their head. Her claws were fully extended.
‘I knew it was a lie,’ she spat. ‘Well, you won’t live to enjoy your revenge.’
‘The flood is not our doing,’ said Malien, putting her hands up.
‘You’ll die for it just the same,’ said Liett.
She sprang and, before Malien could do anything to defend herself, the claws went around her throat. Nish went for his sword, knowing it was hopeless, but it was knocked out of his hand.
‘This serves you not at all, Liett,’ Malien managed to croak.
She looked up and Liett followed her gaze. Another rock fell, smashing into the edge of the peak and spraying splinters of stone everywhere.
‘Those air-dreadnoughts rise higher than you can fly, Liett. One such missile, perfectly aimed, can destroy the tower and the port-all that creates the gate. And then we’ll all drown. You, me and all of your kind. But we can save you.’
At the word drown, Liett’s crest, the only part of her skin that had colour, shimmered with emerald green. She shuddered, then let Malien go. ‘After all that’s been done to us, I can’t bear to put my trust in humankind.’
‘I’m not humankind, Liett, I’m Aachim. My people have never waged war on lyrinx, and my record is inscribed in the pages of the Histories for all to read. Besides, it’s not necessary to trust, merely to gamble. Lyrinx are not averse to a wager, I’m told.’
It seemed to hit the right chord. ‘Everything in life is a gamble,’ said Liett, letting her go. ‘All right – go up in your flier. Already the water laps around my people’s ankles – I can sense their cries from here.’
Three air-dreadnoughts now wheeled high above the tower. ‘They’re armed with javelards,’ said Nish.
‘So are we,’ said Malien. ‘Get to your post.’
As soon as he was in the shooter’s position, Malien took the thapter straight up, relying on the lyrinx to get out of her path. The air-dreadnoughts were large, Nish saw, but had only a small crew, sacrificing everything to carry the greatest weight of stones and still rise beyond range of the lyrinx, whose claws could destroy an airbag in seconds.
Further off, two thapters cruised in circles, guarding the air-dreadnoughts. They turned towards him. Five against one – odds even Malien would be hard pressed to even.
‘I’ll go directly behind that one,’ she shouted over the wind, pointing at the nearest air-dreadnought.
Nish raised a hand, not sure he understood her strategy, but she was looking forward, intent on her course. His eyes were already watering. He wished he’d thought to bring goggles.
