They headed down a long hall thick with dust and ash which long ago had been scalloped into ripples by the wind. There were no tracks apart from one set of boot marks going in and another back out, and the occasional trail made by a lizard’s tail. The boot marks were Gilhaelith’s. So he’d been back here after escaping from Alcifer.
‘The earth has been my science and my Art, for all my adult life,’ said Gilhaelith, his long strides puffing up ash at toe and heel. ‘If I am to leave here forever, there’s one small thing I have to take with me.’
They went down several floors. Nish was amazed at the wealth of the place, and the austere beauty. Both his father and mother had been wealthy but they’d possessed nothing like Nyriandiol. Even more amazing, it had not been looted. Perhaps Gilhaelith’s reputation was too uncanny.
Gilhaelith opened a door into a dark room, touched a quartz sphere above the door and soft light spread out. The room was empty except for a sphere, about half a span across, turning slowly in a metal bowl on a round wooden base set with brass graduated rings and pointers that could be slid around them.
‘This,’ said the mancer.
‘Not so small,’ said Nish. It appeared to be a model of Santhenar. The side facing them showed Lauralin and the ocean to the east, and part of another land, beyond the equator to the north. He walked around it, studying the islands and continents. ‘I’ve often wondered what was beyond those seas.’
‘So did I, Nish,’ said the mancer. ‘All my life I’ve wondered, and now I know.’
‘It must have taken you a long time,’ said Nish.
‘Half a lifetime. I completed it only recently, in Alcifer, with the aid of the lyrinx. They’d flown the entire world in their early days here, mapping it on charts made from tanned human skin.’
‘How did you get away?’
‘The globe can be used for more than I told them. At an early stage I tapped into their sentinels and discovered what they had planned for me – among other things.
‘I’d given up hope of escape when fate took a hand. You, Tiaan and Irisis attacked Alcifer with the fungus spores. A clever idea – I never would have thought of it, but nothing could have been more cunningly designed to panic them. On the night of your attack, their watch relaxed, I used the globe to conceal myself from their sentinels and walked out of Alcifer to the port. I’d left a boat there when I came from Fiz Gorgo, and I sailed it across the sea. Once in Taltid I signalled a passing air-floater and convinced them to bring me and the globe here. I left it here for safekeeping and they flew me down to Lybing in time for the conclave.’
The holes in his story gaped as wide as the front door, but Nish didn’t question Gilhaelith further. He took a closer look at the globe.
It was exquisite. The surface appeared to be a kind of glass, and although the mountains were raised in relief, they were below the surface, which was smooth and so cold that when Nish touched it with a finger, his skin stuck to the glass and had to be eased off.
‘Don’t touch,’ said Gilhaelith. ‘There could be … unexpected consequences.’ He drew on a pair of silken gloves and traced a fingertip across the surface, which had hardly any dust on it. ‘It’s my life’s work.’
‘Surely not?’ said Nish. A skilled artisan, such as Irisis, could have made it in a few months.
‘It’s more than it seems,’ Gilhaelith said mildly. ‘This is not just a globe, Nish. It’s a geomancer’s model of the world, meaning that each part of the model corresponds to a part of the world. Had I power enough, I could change the world, within limits, by changing the model.’
‘Is that why you want it?’ asked the pilot in a meek little voice.
‘No, Kimli. I’ve never sought to change the world, merely to understand it. But I have a different purpose today. That call Daesmie picked up was from Matriarch Gyrull, one of the six matriarchs, and pre-eminent among them on the rare occasions when a supreme leader is required, as at the moment. She must have escaped from the collapsed tunnels in Oellyll, but the infection has taken hold. She’ll soon be incapacitated, if she’s not already.’
‘That must be the bitterest of blows to them,’ said Nish.
‘Not in the sense that we value a leader. The moment Gyrull became matriarch, she would have begun training successors. It’s what she’s bearing that’s important.’
‘What are the Sacred Ones?’ said Nish. ‘Her children?’
‘The cultural relics of the lyrinx.’
‘I didn’t know they had any culture.’
‘They gave up their ancient culture in their struggle to exist in the void. That’s why the relics found in the Great Seep are so important. They’ll do anything to protect them. The matriarch must have been ferrying the relics to a safe place, far away, but was struck down by the disease. Perhaps her escort is similarly afflicted; they’re calling for help and we have the chance I never imagined would come.’
‘Where is she?’
‘I don’t know.’ He held up his hand as Nish began to speak. ‘But my geomantic globe may tell me.’
‘How?’
‘If you keep quiet, you’ll find out. Stay here.’
He was only gone a few minutes, returning carrying a small timber box which he set on the table. Inside were many lemon-yellow crystals, pyramidal on each end.
‘Brimstone, or sulphur,’ said Gilhaelith. ‘Don’t touch them.’
‘Why not?’
Irritated, Gilhaelith picked out the smallest and placed it in the palm of Nish’s hand. It lay there for a few seconds; then, with a crackling sound, shattered to pieces. ‘That’s why. Just the warmth of a human hand can fracture them. But if one is careful …’
With gloved fingers he stroked another crystal, faster and faster, then held it out between forefinger and thumb. He passed it back and forth over the surface of the globe, without ever touching it, sweeping a series of closely spaced lines from the Sea of Thurkad to the curve of the Great Mountains. Gilhaelith began in the south, at the shores of the Karama Malama, and continued north, every so often stopping to rub the crystal vigorously.
Nish didn’t question him. Gilhaelith’s attention was focussed on the surface of the globe. Nish did the same. Finally, as the lines swept across the drylands of the Tacnah Marches, between the City of the Bargemen and the Ramparts of Tacnah, a tiny lemon-yellow light winked through the surface.
Gilhaelith thrust the box of brimstone crystals in his pocket and gave him a triumphant look. ‘That’s where they are.’
‘How do you know. What was all that about?’
‘Like calls to like, Nish. Among the relics is a large crystal, and some smaller ones. The larger one is known as The Brimstone. My crystal called and The Brimstone answered.’ Gilhaelith gathered the geomantic globe up. ‘Bring that crate over, would you?’
Nish lugged the box across. Gilhaelith nestled the globe inside, carefully protected in folds of indigo velvet, packed the turned base, put down the top, took one of the rope handles and signed to Nish to take the other. They carried the crate out to the thapter.
‘I know one should never become sentimental about material things,’ said Gilhaelith, ‘but I spent the most contented years of my life here. If you would give me a moment. Please wait in the flier.’
Nish and Kimli handed the crate up into the thapter. Gilhaelith stood on the stone wall, staring into the crater. Fumes were now belching out of it; an explosion sent boulders arcing through the air.
Gilhaelith watched them rise and fall. One landed on the crater’s rim just a few hundred paces away. Another crashed through an outside walkway of Nyriandiol, tearing most of it away and sending it plunging into the bubbling lake.
He took something out of his pocket. It looked to be a smooth round rock with a hollow in the centre, though it was shiny, as if it had been polished. Gilhaelith weighed it in his hand, tossed it up and caught it, then drew back his arm and hurled it high, out towards the centre of the crater. As it fell he spoke five lines in a language Nish had never heard.
