Alchymist

'It's still stuck in the tar,' said Merryl. ' I don't think —’

'I'll try to work it free.'

He peered anxiously ahead. A billow of black mist was rolling towards them. Tiaan pulled down the hatch and fastened it. It became dark inside, except for the subtle glow from the plate in front of her. The front panel thinned to transparency. The outside was dimly lit by glowing globes that shone intermittently through the fog.

She wiggled the lever back and forth, ever so gently. The whine rose and fell. With a delicate shudder the construct pulled free and rose in the air until its base was at the level of the black fog. Tiaan edged it forwards.

'Straight ahead or to the left?' she said, after they'd been travelling a while.

'The way out into the main pit is straight ahead, but we may not be able to get through that way …' Merryl was looking at her expectantly. 'Is something the matter?'

She realised that she was frowning. I originally came here looking for Gilhaelith. He's a strange, unlikeable fellow, but he was good to me.' Even though he'd cared more for the amplimet than about her safety, Tiaan had to know that he was safe.

'He's an important man,' said Merryl. 'Surely the lyrinx will have taken him with them.'

'I was important to them, yet they panicked and left me behind. They may have abandoned him as well. Do you know where Gilhaelith was working?'

'In a tunnel excavated into the Great Seep.'

A tunnel in liquid tar? How can that be?'

'They froze it first.'

'How?' said Tiaan curiously.

'One of their Arts.'

'If he was left behind, can he possibly still be alive?' she said to herself.

'Not if he's still in the seep.' He looked through the front. 'But, perhaps, in the tunnels near it …We can go that way. It's not much further.’

Merryl was a man of the same heart as Tiaan. She thanked him, silently. 'He treated me kindly. I have to know.'

'Then go straight on.'

They came to a high point in the tunnel where the heavy black mist had not reached. Merryl cracked the hatch open to let in fresh air, but it stank so badly that he quickly closed it again. The construct went down sharply, plunging into fumes which the globes could not penetrate. Tiaan had to creep along, and even then was continually bumping into the sticky, gritty walls.

They turned a sharp bend, then another that formed the other half of an 'S', and the black fog thinned. Ahead, two tunnels diverged at a shallow angle.

'Which way?' said Tiaan.

Merryl was staring blankly through the screen. 'I'm . . , not sure. The fog has confused me. Have we missed an intersection?'

'We could have missed fifty for all I could see.'

'Take the left. I think:

After a few minutes, Tiaan felt the right-hand side scrape on the sandy wall. Shortly afterwards the other side did the same and the construct shuddered to a stop.

'It's the wrong way, said Merryl. 'Better go back.'

'I hope we can,' Tiaan muttered.

After much jerking and heaving the construct began to move backwards. They had been heading down the other tunnel for some minutes when Tiaan saw a red glow in a cross-tunnel to their left.

'We're running out of options,' said Merryl. 'Can you go faster?'

She increased speed as much as she dared, following a zigzag path away from the burning area until they hit a broad tunnel that ran straight. There were no fumes in it and they made good time. The walls and roof here were yellow sandstone, hardly tar stained at all. After ten minutes they came abruptly into blackened rock and then, where the tunnel opened out, into solid tar. The tunnel kept on.

'Is this where Gilhaelith was?' Tiaan did not like the feel of the place.

'He would have been some way ahead. We're close to the outer edge of the Great Seep — the solid edge. In a few spans it becomes soft and beyond that it's liquid tar for a league.’

'How did they tunnel it? And why?'

Merryl spoke to the huddled slaves in a language Tiaan did not know. A woman answered in the same tongue.

'They used devices powered by phynadrs,' said Merryl, 'to draw the heat out and freeze the tar hard. Why, I cannot say, only that it was mighty important to them. Matriarch Gyrull worked there every day, and a matriarch does not risk her life needlessly.'

They crept on. Objects were strewn here and there as if discarded in flight — rotting, tar-stained remnants of clothing, a small wooden chest. Further on was a distinctly human-looking body.

Tiaan caught her breath. Not Gilhaelith, surely? She drew the construct alongside, opened the hatch and looked down.

The body was small, female, and tar-impregnated. 'It has a .., withered look; Tiaan said. 'As if long dead.'

'Many people, and many animals, must have become stuck in the tar over the aeons, and been carried down into the depths. I saw a number of them over my time here, all perfectly preserved. You need shed no tear for her, Tiaan. She's been dead hundreds of years, at the very least.'

'I'll go on, just in case …' She edged the construct down the tunnel. I thought you said they tunnelled in a long way.'

About a hundred spans, I heard.'

'We're only in twenty and I can see the end,' said Tiaan.

She lifted herself up on the side, the better to see. The end of the tunnel was but spans away, a smooth, shining black bulge dotted with fragments of wood and cloth. 'It's moving!' Warm tar was creeping towards them like molasses squeezed through a hole. The tunnel had collapsed, 'If Gilhaelith was in there, he's dead.'

Five

Merryl gripped her shoulder. 'Was he special to you, Tiaan?' 'I wouldn't say that we were friends, for he had none. Gilhaelith was quite the strangest man I've ever met, and totally absorbed in himself. Yet he was good to me and I can't forget it. We'd better go, if we're to get out.'

Reversing the little construct, Tiaan turned it about and went back the way they had come. At the first intersection, Merryl said, 'Go left.'

She headed that way but was soon confronted by a baleful glow and another creeping fume.

'There's fire ahead, Tiaan. Try the other way.'

To the right they encountered a cave-in that completely blocked the tunnel. There was no hope of clearing it, for the fumes were knee high and rising. They turned back to the junction and took the middle path, their last hope.

'Fire,' Merryl said dully, after they had moved less than a hundred spans.

Tiaan kept going until it was certain there was no way past. 'What now?'

'Resign ourselves to death.'

It was hot here. Tiaan went back to the entrance to the tar tunnel. She could not resign herself to dying. Turning the construct again, she stared at the oozing face of the tar.

'Tell me about the Great Seep, Merryl.'

'It's a good league across, and hundreds of spans deep. Some say it's bottomless. Things, and creatures trapped in it, sink down and sometimes appear again, countless years later, with the wheeling of the slow currents in its depths.'

'If we remain here,' she said absently. 'We'll be dead within the hour.'

'I'd-say so.'

'How long would the air in the construct last with the hatch down, and all of us inside?'

'I don't know. Two hours? Three? Four, possibly.'

'Then let's live those extra hours. Let's risk it.' Tiaan slammed the hatch, took a deep breath and moved the construct gently forwards until it met the convex face of the tar.

Merryl's eyes met hers. Tiaan's eyes were alive for the first time since he'd met her. 'What have we got to lose?'

The construct met resistance and stalled. Tiaan moved the controls, just a tickle. The skinned tar broke and the machine surged into treacly material that smeared across the screen. Everything went black.
