They continued upward along the spiralling passageway with the muted roar of the waterfall in Ghwerig’s treasure-cave growing fainter and fainter. Then, just as they moved beyond the range of hearing, the sound seemed to change, fragmenting its one endless note into many, becoming a complex chord rather than a single tone – some trick perhaps of the shifting echoes in the cave. With the change of that sound, Sparhawk’s mood also changed. Before, there had been a kind of weary satisfaction at having finally achieved a long-sought goal coupled with the sense of awe at the revelation of the Child-Goddess. Now, however, the dark, musty cave seemed somehow ominous, threatening. Sparhawk felt something he had not felt since early childhood. He was suddenly afraid of the dark. Things seemed to lurk in the shadows beyond the circle of light from the glowing sword-tip, faceless things filled with a cruel malevolence. He nervously looked back over his shoulder. Far back, beyond the light, something seemed to move. It was brief, no more than a flicker of a deeper, more intense darkness. He discovered that when he tried to look directly at it, he could no longer see it, but when he looked off to one side, it was there – vague, unformed and hovering on the very edge of his vision. It filled him with an unnamed dread. ‘Foolishness,’ he muttered, and moved on, eager to reach the light above them.

It was mid-afternoon when they reached the surface, and the sun seemed very bright after the dark cave. Sparhawk drew in a deep breath and reached inside his tunic.

‘Not yet, Sparhawk,’ Sephrenia advised. ‘We want to collapse the ceiling of the cave, but we don’t want to bring that overhanging cliff down on our heads at the same time. We’ll go back down to where the horses are and do it from there.’

‘You’ll have to teach me the spell,’ he said as the three of them crossed the bramble-choked basin in front of the cave mouth.

‘There isn’t any spell. You have the jewel and the rings. All you have to do is give the command. I’ll show you how when we get down.’

They clambered down the rocky ravine to the grassy plateau and their previous night’s encampment. It was nearly sunset when they reached the pair of tents and the picketed horses. Faran laid his ears back and bared his teeth as Sparhawk approached him.

‘What’s your problem?’ Sparhawk asked his evil-tempered warhorse.

‘He senses Bhelliom,’ Sephrenia explained. ‘He doesn’t like it. Stay away from him for a while.’ She looked critically up the gap from which they had just emerged. ‘It’s safe enough here,’ she decided. ‘Take out Bhelliom and hold it in both hands so that the rings are touching it.’

‘Do I have to face the cave?’
