Carnelian stared at the long mirror face, swallowed. 'Is there not a risk that my father will die unless you heal him now?'

'Do you presume to greater wisdom than the Wise?' the homunculus said severely.

Carnelian was unable to respond.

'Good, then we shall proceed to the Labyrinth.'

'I won't go with you,' said Carnelian, lapsing into Vulgate.

Aurum whisked round. 'Why will you not, my Lord?'

Carnelian closed his eyes to find composure. 'I wish to go to my own coomb, my Lord.'

'You would desert your father?'

Carnelian looked at the old Master. 'I would follow his command.'

'This command must have been given you some time ago. Much has changed since then, my Lord.' 'Nevertheless.'

This is outrageous. Immortality, you must stop this.'

The matter does not concern us,' said the homunculus.

Aurum's mask bore down on Carnelian but he refused even to flinch. The Master swung round on Jaspar. 'Since it seems Suth Carnelian's mind is made up perhaps my Lord would condescend to accompany him.'

Jaspar snorted. 'And why pray should one wish to do that?'

'Because you would find me grateful.'

Jaspar turned to Carnelian, saying loudly, The gratitude of House Aurum is a prize to be devoudy desired, neh? One's coomb is near your own, cousin, so there would be only a little inconvenience. Besides, we might even manage to amuse each other on the way.'

Carnelian was in no mood to be amused or to oblige either Master, but nor did he want to be left alone in this strange new world. He lifted his hand in agreement.

Jaspar held Carnelian back when he made to move towards his father. Carnelian shoved his arm away.

Jaspar flared his palms. 'You misunderstand, my Lord. Our way lies along a different road.'

'But I thought…' Carnelian's resolve crumbled. He had not expected to have to part from his father so soon.

Aurum turned towards Jaspar. 'My Lord, your father must come to the Labyrinth immediately to represent his faction.'

That will not be possible. The Lord Imago will take several days to prepare himself.' He waved a vague gesture. 'One will have to inform him of our… our mission, a household will have to be readied to accompany him.' He sighed. 'My Lord knows well what tedious arrangements one is required to make before planning even the briefest sojourn at court.'

'Make sure that he is there in three days,' said Aurum and turned away.

'My Lord Aurum?' said Carnelian.

The Master turned back.

'Will you send me word if my father improves, or if he were to.. .?'

Aurum's hand snapped agreement, and he strode away.

Carnelian knelt at his father's side. He glanced at the metal face and then found the hand and cursed his mask that stopped him kissing it. He stood back as the bier was lifted and mournfully watched it move away with the Grand Sapient, the Masters and the others.

'Alas,' said Jaspar beside him.

Carnelian turned to him, surprised. 'You share my pain to see them go?'

Jaspar laughed. 'On the contrary, it is a blessed relief. One was bemoaning the necessity of more walking. It is customary to send ahead to one's coomb for suitable transport and an escort of one's tyadra.' He pretended to look around him. 'As you can see, cousin, we shall have neither convenience.'

The Master's flippancy angered Carnelian. 'We will get nowhere unless we move on.'

Carnelian looked for his father and was dismayed to see him being carried into the silver house. A protest was on his tongue when the whole edifice lurched into movement and he noticed its skirting of wheels and realized it was a chariot. The thought of his father locked inside with the Sapient and the homunculus made him shudder.

'Will the Wise heal him, Jaspar?'

'Grand Sapient Immortality is guardian to all the lore of his Domain. Short of divine intervention there is no power in all the lands that can do more for the Ruling Lord Suth than he.'

Fearing hope would unman him, Carnelian said quickly, 'Which is our road?'

Jaspar pointed down an avenue running towards the lake.

Carnelian saw the silver chariot veering off to the right, disappearing into the forest of stone.

'Our road is the straighten' Jaspar sauntered off.

Carnelian watched the last silver panel of the chariot wink out and almost ran after it. He felt as trapped as the Quyans in their stone. Their dimple eyes saw through his flesh. They mobbed the road all the way down to the lake. He strode after the only companion he had left, his enemy, Jaspar.

'Curse the sun, it makes me sweat!' growled Jaspar.

Carnelian threw a fold of his robe over his head to stop his mask heating. A sun ray had split his head in two. He squinted past the ache. Ahead there was something like a burning barricade set across the road. He was sure that he could feel its waves of heat beating against him. Soon he saw that its flames were formed by a hillside of carved and gilded columns. The road divided to run round them and edging one fork there was a narrow rind of shadow.

They made for this shadow and stopped to rest, pressing their backs against the cool gilded stone. The air still burned Carnelian's lungs. His robe clung to him. He pinched some of the cloth to peel it off his skin and wafted it. Jaspar was panting.

Carnelian turned to the column he had been leaning against and saw that it was the shins of a narrow Lord. Hundreds more crowded up the slope. The carving was unlike the angels. It was sharp and fresh and the curving golden limbs seemed almost alive.

The Clave,' said Jaspar, looking at Carnelian. He drooped his head and flapped his hands at it like fans.

'Where the Great… meet?' said Carnelian.

They walked round rubbing against the cool legs of the golden crowd, keeping in their delicious shadow. They came to where a stair of snowy marble wound up between the giants.

'Is it cool up there?' Carnelian asked.

Jaspar shook his head. The Clave is a bowl in which we meet only when the sun is behind the Sacred Wall or sometimes at night. Now, it will be incandescent.'

They passed several more stairs before they reached the shadow's end. 'One longs to linger here, but alas we must go on… it should be cooler by the lake.'

Carnelian watched Jaspar stand there for some moments as if he were gathering up his courage, then the Master pushed forward and was burned up in the glare.

Jaspar swung the bronze clapper on its ropes. Then the heart-stone bell seemed the only stillness in a trembling world. Carnelian did not hear it peal. He had lost every sense but sight. The Pillar of Heaven was there, a filament from the Singing Turtle's heart, where it had been since the creation, a mountain holding up the immense weight of the sky. The Sacred Wall was set about its axle like the rim of a wheel. Around the Pillar spread the terraces and water meadows of the Yden, the Gods' own Forbidden Garden floating in the midst of the Skymere.

They come,' a voice said remotely in his ear, waking him.

Carnelian followed Jaspar's pointing finger and saw a needle detach itself from the Yden's rim and darn a white stitch into the perfect sapphire of the lake.

'We shall wait up here in the shade,' said Jaspar.

Carnelian looked down the flight of steps that fell precipitously to the water's edge. Carvings of stone flanked it all the way. He put his hand out to touch the nearest one, in whose shadow they sheltered. The flow of years had smoothed it but still he could see it was a turtle. He looked out across the lake, daring to be possessed again. He ran his eyes round the outer wall of the crater like a finger round a bowl. All along its purpling length it pleated like cloth and in the folds jewelled fragments lodged, the coombs of the Chosen.

Carnelian's eyes settled back to the mirrors of the Yden and the strip of earth that moored it to the cliff upon which he stood. There along that causeway a fleck of light caught in his eye. It glinted again like a signal. He lifted his hand out as if he would pluck it from the distance.
