The phynadr was powered by the field and drew heat from the area around it. He had no idea how it worked but there was no doubt of its effectiveness. The tarry rock, now frigid, was brittle and easily broken. His crystals told him that the device took prodigious amounts of power from the field, which was weaker than before.
The tunnel went forward in cooling stages followed by excavation. By late that afternoon, the fourth day of tunnelling, they broke through the last of the rock into the pure tar of the Great Seep. Now the work became hazardous in the extreme. Liquid tar was all around them, kept out only by a thin, frozen layer that was, relatively speaking, as fragile as an eggshell. If the pressure found a weakness, or just one of the cooling rings failed, the tunnel would collapse and they would be entombed in hot tar. The floor on which they stood shuddered from time to time.
Gilhaelith was idle now, but never bored. He observed, noted and classified everything around him. The lyrinx were of particular interest, and he saw that they were not completely comfortable in their great bodies or, at least, their outer skin. The lyrinx were constantly scratching, shrugging their shoulders, working their limbs and easing the position of their armour plates. Perhaps there was a disadvantage to all the flesh-forming they had done to their unborn selves, in order to survive in the nightmare environment of the void. Gilhaelith was working in an embayment down the tunnel, well out of the way of the diggings. He had learned much about the node, another step toward his ultimate goal, but that was as far as he was going to get here. The war drew ever closer and it was time to get out before he was trapped. He felt sure he would be able to escape, despite how carefully the lyrinx watched him. They allowed him unfettered use of his tools, and that should be enough. But before he left he had to get the amplimet. He wished he could free Tiaan too, for he did care about her, but, no matter how much he might regret it, she had to be left behind. He could not carry her as well as his scrying globe, and he could not get out without it.
Adjusting it, and sensitising it with an appropriate crystal, he sought for the amplimet. Gilhaelith found it at once, so quickly that momentarily he wondered if it had found him.
His belly throbbed. The colic had been worse than usual since he'd come to Snizort, for which he blamed the bland food they gave him. None of the delicacies he was accustomed to were obtainable here.
The amplimet was around Tiaan's neck in the patterning chamber, and a patterning was going on. He sideslipped that process. Time was everything now and he could not be distracted by irrelevancies. The chamber was empty and there were no guards. Good. He worked out a route to it, and the way out, then scried back to check on the amplimet again.
It was flashing furiously. Was it communicating with the patterner, or the node? It was hard to tell – the patterns seemed deliberately blurred. Surely the node, which seemed more unstable than ever. And the patterner! That bothered him. Was it trying to alter the patterning? What for? And what to?
Hitherto Gilhaelith had paid no more attention to the patterning chamber than he had to the rooms where the lyrinx carried out flesh-forming and other dubious activities. Now he turned his attention to the growing torgnadr and realised that it was a node-drainer. And if the amplimet controlled such a device, it controlled all the power of the node.
A looming disaster for both lyrinx and humanity, but a fabulous opportunity for himself. It was the chance to learn much more about the amplimet, by seeing exactly what it did.
'No progress today, tetrarch?' snapped Gyrull.
Gilhaelith started and barely managed to control his face, but Gyrull had other things on her mind and kept going. The field was surging erratically and at present the freezing coils were too effective. The lyrinx had broken a number of matlocks, the metal going so brittle in the intense cold that the tools snapped on impact. It was retarding progress and had to be remedied quickly.
He went back to his work, keeping a wary eye out now. His scrying was a delicate business, for he knew not what the amplimet might be capable of, and did not want its attention to turn on him.
However, after several days of such work Gilhaelith grew bolder, for he was beginning to see the pattern. The amplimet seemed to be drawing filaments of force – almost invisible threads of gossamer – out of the field to itself, to the patterner and to many other parts of Snizort. Power did not flow along those threads, yet he could see faint pulses of light. Why this network?
'Come, tetrarch, you are needed at the front,' said Gyrull.
Reluctantly, he began to collect his gear.
'Leave it! There's no time. I'll have it packed for you.'
Packed? Gilhaelith had no choice but to follow. He was not yet ready to break out and could not do it without hours of preparation, but her use of that word alarmed him. The tunnel extended hour by hour, day by day. Cooling rings were spaced every ten paces along it, each with its mushroom-like phynadr maintaining the cold that kept them alive. The work was slower now; the broken tar had to be removed carefully in case they broke out of the frozen zone. Late on the tenth day of tunnelling, when they were nearly a hundred paces into the seep, Gilhaelith was called to try his scrying crystals again. His worries had proven fruitless; Gyrull still allowed him access to his tools, though only for a few minutes at a time.
In the middle of his reading, the pair of lyrinx at the face ceased their pounding and levered with a bar. A curving slab peeled away to reveal something lifelike embedded in the black material. Putting down his instruments, Gilhaelith went to see what it was.
It turned out to be the body of a wildcat, as long as Gilhaelith was tall, with a huge head and jaws that could have taken his leg off. It was so perfectly preserved that it might have been alive.
The following morning the diggers found another, smaller predator, more like a jackal, and that afternoon a wild bull with long curling horns. 'The beast must have been trapped in the seep,' said Gilhaelith, 'attracting the predators which died the same way.'
'Put two feet in wet tar,' said the lyrinx to his left, 'and you would not have the strength to pull them out.'
Gilhaelith finished his readings and this time did detect something. 'That way.' He pointed left of the tunnel centreline, down at a slight angle.
The lyrinx adjusted their cooling ring and continued. They encountered other dead animals as the tunnel slowly extended: once a pair of seagulls, another time a house cat, and then a pair of snakes the size of pythons, wrapped around each other. After that they continued in clean, glassy tar. By the fourteenth afternoon the tunnel was shuddering all the time.
As Gilhaelith walked back that night, a crack opened in the floor in front of him. A wedge of tar forced its way in, whereupon the lyrinx manning the nearest annulus worked her controls and extended the freezing zone. Another lyrinx broke off the solidified obstacle with a hammer. As Gilhaelith continued he saw other filled cracks. In some places there were more cracks than wall. The shell was barely surviving. The pangs in his belly grew worse.
Gilhaelith tried many times to get back to his own work, but Gyrull always needed him somewhere else, even if just to stand around and watch. At night he was escorted to his room to sleep, without his equipment, and a guard waited outside the door. She was taking no chances. Did she suspect what he was up to? Gilhaelith tried every argument to get his devices back but none availed him, and without them he was helpless. Most nights he lay awake, brooding and suffering pangs of colic. He could do nothing about that either. He had not seen Tiaan again, and did not expect that he would. Gilhaelith had been touched that she'd cared enough to follow him, whatever her true motivation. She certainly had courage, unfortunately marred by an appalling lack of judgment, but he wished she'd stayed away. He cared about her. Not as much as for the amplimet, of course, but more than he cared for anyone else.
