‘They must be mighty falls,’ said Tiaan.
‘Indeed, for the Foshorn is like a dam holding back the weight of the Sea of Thurkad and the Western Ocean behind it. The bed of the Dry Sea lies two thousand spans below the Sea of Thurkad, which has a powerful urge to reclaim it. The water races down the Hornrace as fast as this thapter can fly, but compared to the vastness of the Dry Sea it’s no more than a dribble down a lunatic’s chin.’
‘Perhaps I’m seeing a node associated with the chasm,’ said Tiaan. ‘No wonder it’s so huge, and so different.’
‘No wonder,’ said Malien, though there was a wary look in her eye. ‘Let’s see.’
They kept to a slow pace in order to lessen the strain, so it was late in the afternoon before they finally came in sight of the Hornrace. The thapter crept along the coast, which was incredibly rugged here, the mountains rising directly from the sea. They passed by one black headland after another and Tiaan felt her nerves tighten, as if each headland represented another turn of a clock spring. She already felt overwound.
The swirling patterns were everywhere now; she could hardly think for them. Flydd came up with a mug of tea, which she drank in a single draught. It tasted of ginger and the bitterness of willow bark, and shortly her headache began to ease.
Malien rounded another jagged headland and the tension snapped so tight that Tiaan could hardly draw breath. Malien took her hand, and Flydd – the scrutator himself – put his arm around her and held her up. Another dark headland loomed ahead.
‘The next will be the last,’ said Malien, controlling the thapter expertly with one hand. ‘Brace yourself.’
They rounded the last headland and the field struck Tiaan in the face like a flail. She cried out. Flydd opened the platinum box, Tiaan reached in and touched the amplimet, just for a moment, and the tornado of light and colour eased enough for her to open her eyes.
Just below them, the sea swirled in a series of whirlpools between rocks that stuck out of the water like the teeth of sharks, only black. Beyond, the current raced towards a dark slot in the cliff.
‘Go up a little,’ said Flydd as air currents buffeted them violently. He closed the platinum box, to Tiaan’s regret.
The thapter rose a few spans and the eddies grew less. They crept forward, rocking in the air. Forward, forward, and suddenly the chasm of the Hornrace opened up in front of them. The black cliffs towered so high that Tiaan had to crane her neck to see their tops.
A wild gust – a gale of air – struck the thapter and sent it tumbling. Had not the hatch crashed down they might all have been thrown out.
‘Straps!’ yelled Malien, clinging grimly to the controller.
Flydd put his arm through one of the sets of straps hanging from the back wall, then whipped two others across Tiaan’s shoulders and buckled her in. He did the same for Malien, and lastly for himself.
Malien gained control of the thapter but a wilder gust immediately flipped them upside down. She righted the machine and it was tossed the other way.
‘Get out of here,’ roared Flydd. ‘The torrent is drawing a gale of air through the Hornrace and it’ll smash us on the Trihorn.’
Malien had gone pale. She tried to turn the thapter but it shook violently, swung towards the black cliffs, rotated one hundred and eighty degrees but kept going, hurtling backwards down the Hornrace. Below, Tiaan could hear compartments flying open and gear crashing everywhere.
‘The gale is too strong,’ said Malien, fighting the controls.
‘Give the thapter more power.’
‘I’m doing the best I can. It’s hard to take it from the node I’ve been using.’
‘What about the big node?’
‘I can’t sense it.’
‘Tiaan?’
Her skin crawled at the thought of trying to draw power from such a field. It would turn them all inside out.
‘I dare not,’ she whispered. ‘It’s beyond me.’
‘What do I do?’ cried Malien. ‘Flydd?’
‘Turn around,’ said Flydd through gritted teeth. ‘Don’t fight the wind. You’ll have to go with it.’
In turning, an eddy flipped the thapter over and a downdraught hurled them at the torrent of black water. Tiaan bit down hard on a scream. Malien pulled up on the flight knob, the thapter struck the water and skipped like a stone, the blast from its base sending steam corkscrewing up all around them like miniature tornadoes.
‘Go up! It’s deadly this low,’ he yelled.
‘I know it!’ she snapped. ‘It … doesn’t want to go up, Flydd. The downdraught is too strong.’
‘Try to get out into the middle.’
‘I’m doing all I can,’ Malien said, fighting the controller.
The thapter edged toward the middle of the Hornrace. The wild air eddies were fewer there but the gale was stronger, hurling them from side to side. They skated across to the southern side on a rising column of air. Tiaan closed her eyes, sure they were going to strike the basalt wall.
Malien took advantage of another eddy to carry them away, and managed to lift the machine a little. The dark cliffs of the Hornrace were rushing past. Tiaan had never gone so fast. How could Malien control the little craft?
Somehow she did. ‘We’re nearly halfway down the Hornrace,’ said Flydd. ‘Better try and get out.’
‘I know,’ Malien said crossly.
‘Sorry.’ Flydd explained to Tiaan. ‘At the other end, three pinnacles stand up in the middle of the stream, breaking it into four torrents. Beyond the pinnacles, the race plunges over the mightiest precipice in the world.’
‘The Trihorn Falls,’ said Malien. ‘Misnamed now, for the tip of the third peak collapsed when the earth moved and the Rainbow Bridge fell.’ She eased the thapter upwards. The buffeting grew less for a moment, until a gust plunged them down again. ‘Not as easy as it seems.’
The wild dance continued for another few minutes then, suddenly ceased as, in the distance, a pair of fanged peaks and a stump, almost as tall, rose out of the water. The craft hurtled towards them.
‘Now!’ cried Flydd.
Malien jerked the controller hard. The thapter shot up and with a momentary shudder broke free of the streaming gale above the water into slightly calmer air. She kept going up, though the pinnacles seemed to rise out of the water just as quickly. The thapter was going like a rocket and she couldn’t slow it.
Tiaan held her breath. One minute it looked as though they were going to make it, the next that they would smash straight into the left-hand peak.
‘Up!’ Flydd roared.
‘I’m doing my best,’ said Malien, tight-lipped.
She climbed, curving toward the gap where the third peak had been. An air whirlpool threw the thapter back toward the left peak. The controller was shuddering as if it lacked the power to lift the weight. It felt as though the whole machine was going to come apart. Malien tried again and again but the thapter wouldn’t turn. She just couldn’t reach the gap.
‘We’ll have to try and go over the top.’
Tiaan reached into the box, took out the amplimet and held it against her heart. They shot toward the tip of the peak; they were going to smash into the rock. At the last second Malien coaxed a little extra from the mechanism, the airflow over the pinnacle bumped them up and they soared over and out toward the Dry Sea. The buffeting ceased: they were sailing in clear air.
Malien slowed the machine, curving around so they could take in the majesty of the Trihorn Falls in their wild plunge, a whole sea full of water, down and down, fifteen hundred spans to the floor of the sea. It was magnificent, glorious, unsurpassed in the Three Worlds.
But Tiaan’s eyes were drawn beyond it, back along the top of the Hornrace, to where four black pillars stuck up, two on either side of the chasm. They were all that remained of the Rainbow Bridge.
Around each pillar were immense stacks of cut stone, the foundations for some monstrous structure that was even now being built. One of the piles on the Lauralin side of the Hornrace was already half as high as the bridge pillars, and five times as wide.
