This was the long-dead army of Stone. Banouin stared at them. Their forms were translucent, and shimmered in the moonlight. When they reached the Barrows, instead of climbing them, they passed right through. There was no sound. The advancing line broke into a run. Banouin glanced to his right. There, pale and spectral, was another line, this time of brightly armoured horsemen. Silently they charged at the enemy, swords as pale as moonlight slashing into them. Banouin saw a man stagger back, his arm hacked from his body. Then a spear ripped through his guts and he fell, the spear snapping in two. Horses fell, pitching their riders, who were stabbed mercilessly as they struggled to rise. All the terrible sights of war unfolded in eerie silence before his eyes.

A black crow glided down to the grass close by and stood, its baleful glare fixed on Banouin. Then a voice sounded from behind, startling him. 'These are scenes men sing of, and brag of, and lust after.' Banouin spun round. An old woman stood there, her shoulders hunched beneath a threadbare shawl, her hands clasping a long, crooked staff. Her hair was thin and wispy white, like mist clinging to her skull. She was impossibly ancient. Banouin's heart began to beat wildly. He knew of this woman, this creature of the Seidh. This was the Morrigu, whose promises tasted of nectar and burned like poison. The young man said nothing, but his dark eyes flicked towards the sleeping Bane. 'He cannot hear me, and he will not wake,' said the Morrigu. 'Will you bid me welcome to your hearth?'

'You . . . are not welcome here,' he forced himself to say.

'How that cuts me,' she said with a sneer. 'You, who I delivered safe when nature had decreed your death.'

'I don't know what you are talking about,' he told her.

'Vorna did not speak of me, then? How disappointing. On the night you were born her life was in danger. The babe – the you that was to be – was breeched, and there were no midwives, no druids on hand to save her – or you. So I came. And you were delivered by these old hands.'

'I don't believe you.'

'Yes, you do, Banouin. It is part of the Gift. You always sense when people are lying.'

'Even if you did save me, I don't doubt you had your own reasons,' he said, his voice firmer.

'Indeed I did.' She paused. 'Well, if I am not welcome here, will you at least walk with me awhile?'

'Why would I wish to?'
