The door opened. Yggur was panting. ‘That’s the best I can do. Inouye, rise up over the wall, then head south for Ghorr’s craft. Take it slowly or you may pull out of my concealment.’

‘I can’t see Ghorr’s machine,’ she said.

‘The lookouts will tell you which way to go.’

Flangers went to the bow, while Nish and Irisis hung over the rail on either side, staring into the mist.

‘I can’t say I like this plan,’ Nish said quietly.

‘What plan?’ said Irisis.

‘Precisely.’

They rose slowly. Nish couldn’t see anything but mist, swirling and coiling at the lower levels, streaming across the deck as they rose into the stronger winds at altitude. A little way above the towers, the mist parted below them and he looked back to where the amphitheatre had been.

It had completely collapsed, apart from a triangle of canvas sticking up, like the fin of a shark, where it had draped over one of the towers. Two cables ran into the sky at an angle of thirty degrees, taut as wires. They were still attached to the two air-dreadnoughts, which had been driven out over the forest.

‘Run in the direction of that cable,’ said Yggur, pointing to the nearer. ‘But stay at this height.’

‘How come they didn’t cut those cables?’ said Nish.

‘I used the Art on them,’ said Yggur with a grim smile. ‘No blade can cut them, no fire burn them for as long as the spell holds. To untether themselves they’ll have to take apart the winch drums. It took quite a bit out of me, but it was worth it.’

The taut cable angled up into streaming mist. Yggur had a minute-glass in one hand and was watching the sands run as he estimated how far they’d gone. ‘We should be past Ghorr’s craft now,’ he said to Inouye. ‘Go up and turn to face the other way.’

She did so and he extended his arm, chanting under his breath. The mist spun into a narrow, dark funnel in front of him, like water swirling down a plughole. The funnel extended horizontally, stretching, thinning and wavering back and forth as if searching for something.

Yggur strained, and through the opening Nish caught a glimpse of a section of rigging, then part of an airbag.

‘Too high,’ grumbled Yggur, who seemed to be having trouble holding his arm up. He directed the funnel, whose opening wasn’t much bigger than Nish’s head, down and across and back, then tracked up the port side of the vessel. ‘Is it the right one?’

‘It’s Ghorr’s,’ said Nish. ‘I just saw the top of the thapter hanging below it.’

The funnel was directed up and towards the stern, and there Ghorr stood, issuing orders. A pair of soldiers were hacking fruitlessly at the cable holding his air-dreadnought to the collapsed amphitheatre. The craft was shaking in the wind.

A gust caught the air-floater, heeling it over. Inouye spun the rotor up to full power and slipped the craft expertly up into the lee of the airbags of Ghorr’s much bigger machine. The mist funnel closed over.

‘I can’t hold the concealment much longer,’ said Yggur, clinging to the door. ‘Nish, see if you can see what they’re doing.’

Nish got down on his belly on the deck and put his head over the side. Another wavering tube opened up through the mist below him, though his view was so restricted that it took a while to work out what he was looking at.

‘Ghorr has just whacked the mirror operator over the head. He’s shouting!’

‘He’s been doing a lot of that lately,’ said Irisis, hanging onto his legs as the air-floater lurched one way and then the other.

‘He’s dragged the big crystal-powered mirror around. That must be what they blasted the defences with at dawn.’

‘I dare say,’ said Yggur. ‘Has anyone seen us?’

‘They’re not looking this way,’ said Irisis.

‘He’s pointed the mirror at the cable winch,’ said Nish.

‘It won’t do him any good unless he gets some sun on it,’ said Irisis.

‘If I can make mist, he can break it. He’s getting ready to flee,’ said Yggur. ‘Inouye, take us down.’

‘What’s the plan?’ said Irisis.

‘We board the air-dreadnought from the bow and take it while they’re distracted down at the stern. Flangers, what’s the matter?’

‘He’s got at least ten soldiers against our five,’ said Flangers. ‘Plus a mancer or two. Not to mention the other air-dreadnoughts.’

‘Then we’ll just have to fight all the harder,’ said Yggur. ‘The other machines won’t trouble us. They won’t dare come close enough to board, in case the airbags tangle.’

‘They’re close enough to fire their javelards.’

Yggur waved his hand and the mist obscured everything. ‘Take us down, Inouye. Once Ghorr blasts that cable he’ll be off and this little craft won’t catch him. If we lose the thapter we’ve lost our only chance.’

TWELVE

‘Drop us down to the bow, Inouye,’ said Yggur. ‘Can you do that in the mist, or should I –?’

‘I can do it,’ she said.

‘Klarm and I will attack from behind,’ Yggur went on, ‘and then we rush them. Soldiers, follow me. Flangers, stay back with your crossbow and keep watch. Irisis, get into the cabin and free Malien and Tiaan. Once we’ve secured the air-dreadnought, escort them down into the thapter. Nish, go down the ropes, cut through the canvas and open the hatch of the thapter. Don’t fall off.’

‘Very funny,’ said Nish, who was beginning to sweat. The odds were too great, the plan foolhardy in the extreme. It relied too much on Yggur, who was already exhausted, while Klarm, despite what he’d done earlier, was an unknown quantity. When confronted by Ghorr, might Klarm decide that his oath to the scrutators still bound him? A turncoat might turn again.

‘What if Malien and Tiaan aren’t here?’ said Irisis. ‘We won’t have anyone to fly the thapter.’

‘I’m sure Ghorr would have kept them close by.’

The air-floater dropped so suddenly that Nish’s stomach was left behind. He clutched the rail with one hand and eased his short sword in its sheath. His palms were damp. All that had been saved with such agony could be lost even more quickly. How could Inouye tell where to go anyway? He couldn’t see a thing.

She brought her craft out of the mist and up against the bow with the barest bump. Yggur clambered through the rope rails, limping more than before. Klarm put his hand on one of the stanchions and leapt the ropes, landing lightly on the deck.

‘Let me go first,’ whispered Klarm. ‘He may wonder how I got here, but he won’t think of me as an enemy. It’ll get me a span or two closer. Stay back, around the curve of the deck out of sight. When you hear me use my Art, rush them down the other side.’

Yggur frowned, as if he too had his doubts, then nodded. ‘Go.’

Klarm headed down the port side, moving sure-footedly on the lurching deck despite his caliper. Yggur remained where he was, gnawing at his lower lip, before waving an arm at his soldiers. They followed him, hugging the curved canvas wall of the main cabin.

Irisis caught Nish’s eye and mouthed, ‘Good luck!’

He nodded stiffly. She put her head around the corner to look down the starboard deck. ‘It’s clear, Flangers.’ Weapons at the ready, they went forward into the mist, which had begun to thin just when they didn’t want it to.

Nish turned to his own task. The thapter hung in its nets some five or six spans below the central keel of the air-dreadnought. He could just make it out. It was a long way to go down a rope, though not far enough below the keel for the air-floater to approach it directly. He fingered the coil of rope over his shoulder. He’d already lashed it into a harness at his waist, so it was just a matter of tying it to the side rail and going down.

Once he had done that, Nish checked his knots carefully, slipped through and hung on with hands and feet while he judged his approach. It wasn’t going to be easy; the thapter wasn’t directly below him, but in under the vessel by several spans. He’d have to lower himself a bit further than that, then swing in, catch hold of the net ropes and go down them.
