The nylatl arched its back, pressing another spine into Ryll’s hand. He clung on grimly but Tiaan could see he was weakening as the venom took effect.
She ran around, looking for any kind of weapon. There was not much in the room – the lyrinx used few tools. Grabbing one of the glass and wire cages, she darted behind Ryll, planning to whack the nylatl off. It was the bravest thing she had ever done. If it went for her it would claw her face off.
Tiaan lunged, swinging the cage with all her strength. The nylatl’s head twisted around, the blue tongue aiming a squirt of venom at her eyes. She ducked and the cage smashed against Ryll’s head. He grunted; the nylatl squealed.
The venom splatted on the top of her head, burning straight through her hair. She ran for the water barrel, plunged her head in and scrubbed frantically. Strands of hair floated on the surface.
Brains!
She spun around, water pouring down her face. The nylatl was staring at her. Its claws lifted and dug in like a cat on an armchair.
There was only one thing left to do, and it might well be worse than doing nothing. She crammed the helm on, grabbed the globe, oriented the long side of the amplimet so that it faced Ryll’s head and strove with all her might for power.
Instantly the whispering in her mind grew to a mad shriek.
HUNGRY! BRAINS!
The nylatl’s thoughts crashed around inside her skull like a blind bat, full of incoherent rage. The forced integration must have broken its mind, but its was a deadly cunning insanity. The nylatl wanted to gouge its way into Ryll’s head and take over his body as its own had been invaded. It wanted to make her suffer too, as it had suffered in the integration. And it wanted to destroy and consume, as its own nature had been destroyed and consumed. It was full of malice.
The spire’s magnetic lines of force whirled about her, but even as Tiaan drew power from the field she knew it could not work. That power, the kind that had been used to create the nylatl and make it grow, only fed the creature. She had to have something different, stronger. So strong that the beast would be completely overwhelmed. No choice but to use her fledgling geomancy again. This nylatl could not be allowed to live. If it could overcome a lyrinx so easily, what would it be capable of when it was fully grown?
Down her senses went, to that hollow beneath the base of the iron spire of Kalissin, from whence the magma pool had retreated ten thousand years ago. The domed roof rock formed a series of concentric cracks under the weight of the spire, though the iron froth was still welded to the rock it had penetrated in its molten rise.
To make the roof fall was far beyond her powers, or anyone’s. It might remain in place for another hundred thousand years before gravity finally pulled it down. But just the fall of a fragment into that pool in the distant depths would provide enough energy for her purposes. It might release more than she could handle, and then she would die. Tiaan hesitated, but only for a second. If she did nothing they would both die.
Ryll groaned, breaking her concentration. He was on his back, kicking feebly. His head was covered in purple blood. The bent arm still strained but he was failing.
‘Help!’ she roared, but no one could hear.
Bat’s claws scored through her brain, the nylatl trying to stop her. The pain was excruciating. Tiaan could barely see though it, with her strange, three-dimensional artisan’s vision, to that source below the spire.
Her sight began to break up. Pinholes appeared in everything she looked at. They grew larger and through each she saw a nylatl’s staring eye. It was, despite her efforts, getting at her mind.
Her geomantic strange-sight passed through half a league of solid rock, scanning across the surface of the dome, seeking a piece so precariously held that the gentlest of nudges would release it. She tried one, then another, but the meagre skills the Aachim had taught her were not enough. Tiaan began to panic. She had no idea what she was doing. It could not work.
Ryll let out a ghastly, quivering shriek. She had to succeed. There – a small column of rock was jointed all around in a perfect hexagon, and it was almost cracked through at the top. She used what power she could gather from the fields but could not budge it. More! She drew more. Her head seemed to be boiling like a kettle. She felt the rock crack, but it did not fall.
Tiaan lost focus. With the mad shrieking in her head, and Ryll’s cries and thrashing before her, she could not visualise the source.
Her eyes sprang open. Ryll’s hand lost its grip on the nylatl and fell smack against the floor. The creature dug in its claws. One spine had pierced his scalp and was going up and down, trying to penetrate his skull. The nylatl’s skin was striped in brilliant reds, yellows and blacks, like a poisonous caterpillar. Ryll flashed in delirious, psychedelic colours.
She could not waste a second. Tiaan found that hexagonal column again and suddenly she knew how to use it. The Principle of Similarity, one of the vital principles used by artisans, was the perfect choice here, for the rock column had the same shape as the amplimet. Power cascaded from the field into the crystal and she hurled it at the crack.
It parted. Friction held the column for a moment, and then it fell. She drew power from its motion, just a trickle at first but increasing as it accelerated into the magma chamber.
The bead of light in her amplimet swelled. A focussed beam burst forth. She directed it onto the nylatl. It was not bright enough to hurt it. Not yet. The nylatl arched its back. Ryll kicked weakly. The beam slipped off the creature.
‘Don’t move, Ryll!’ She hoped his hearing had not closed down. Her head felt eaten away inside. The nylatl began to struggle desperately.
In her mind’s eye Tiaan could see the column falling as if she was watching it in slow motion. It accelerated toward that glowing pool of magma.
Her head felt as hot as that magma; white heat licked down her backbone; every nerve fibre in her body was ablaze. Her senses were shutting down one by one. She could no longer feel her feet on the floor. The hot carrion smell of the nylatl vanished. Ryll’s agonised wails cut off. The shrieking chuckle of the creature faded away.
Her sight began to break up at the edges; her eyes felt full of pinpricks. Tiaan clung grimly to sight; she must be able to see to aim. The last she saw, as her vision was going completely, was the nylatl arching up on Ryll’s head, preparing to hurl itself at the real enemy – her!
The black column plunged into the pool, giving up its energy in a burst that blacked Tiaan out. She did not see the brilliant purple light that burst, fan-like, from the amplimet. She tracked the creature’s leap through the field. Just the edge of the fan caught the nylatl, burning the ends off its spines and heating its skin to blister point. Its overheated muscles spasmed, hurling it against the wall so hard that it was knocked senseless.
She did not see the central pulse heat the wall to white-hot, until the metal ran down and puddled on the sloping floor. With an explosion of sparks the light burst through, carving a ragged hole to the outside. Tiaan saw and felt nothing. She lay senseless. The amplimet went out.
There were shouts outside, the lock was forced and Liett scrabbled through the entrance, bent low, followed by Coeland. They stared at the destruction. A red pool of iron, large enough to fill a number of wheelbarrows, was congealing on the floor. Ash and cinders lay everywhere. The room was as hot as a sauna. Ryll crouched in a groaning, lacerated heap.
‘What happened?’ Liett shouted.
One of Ryll’s arms twitched. Liett lifted his battered head onto her knee, wiping blood out of his eyes. She stroked his dull crest. He rolled his head and his eyes lit on the nylatl, lying against the wall. It was covered in pus-coloured blisters. Smoke curled up from several of the spines. Its skin was a bilious yellow. It looked dead.
