‘I thought, Lord,’ I began, then faltered, knowing I was about to be mocked.
‘Oh! You thought the girl came from the heavens!’ Merlin finished the sentence for me, then hooted with derision. ‘Did you hear that, Nimue? Our great warrior, Derfel Cadarn, believed our little Olwen was an apparition!’ He drew out the last word, giving it a portentous tone.
‘He was supposed to believe that,’ Nimue said drily.
‘I suppose he was, come to think of it,’ Merlin admitted. ‘It’s a good trick, isn’t it, Derfel?’
‘But just a trick, Lord,’ I said, unable to hide my disappointment.
Merlin sighed. ‘You are absurd, Derfel, entirely absurd. The existence of tricks does not imply the absence of magic, but magic is not always granted to us by the Gods. Do you understand nothing?’ This last question was asked angrily.
‘I know I was deceived, Lord.’
‘Deceived! Deceived! Don’t be so pathetic. You’re worse than Gawain! A Druid in his second day of training could deceive you! Our job is not to satisfy your infantile curiosity, but to do the work of the Gods, and those Gods, Derfel, have gone far from us. They have gone far! They’re vanishing, melting into the dark, going into the abyss of Annwn. They have to be summoned, and to summon them I needed labourers, and to attract labourers I needed to offer a little hope. Do you think Nimue and I could build the fires all on our own? We needed people! Hundreds of people! And smearing a girl with piddock juice brought them to us, but all you can do is bleat about being deceived. Who cares what you think? Why don’t you go and chew a piddock? Maybe that will enlighten you.’ He kicked at Excalibur’s hilt, which still protruded from the temple. ‘I suppose that fool Gawain showed you everything?’
‘He showed me the rings of fire, Lord.’
‘And now you want to know what they’re for, I suppose?’
‘Yes, Lord.’
‘Anyone of average intelligence could work it out for himself,’ Merlin said grandly. ‘The Gods are far away, that’s obvious, or otherwise they would not be ignoring us, but many years ago they gave us the means of summoning them: the Treasures. The Gods are now so far gone into Annwn’s chasm that the Treasures by themselves do not work. So we have to attract the Gods’ attention, and how do we do that? Simple! We send a signal into the abyss, and that signal is simply a great pattern of fire, and in the pattern we place the Treasures, and then we do one or two other things which don’t really matter very much, and after that I can die in peace instead of having to explain the most elementary matters to absurdly credulous halfwits. And no,’ he said before I had even spoken, let alone asked a question, ‘you cannot be up here on Samain Eve. I want only those I can trust. And if you come here again I shall order the guards to use your belly for spear practice.’
‘Why not just surround the hill with a ghost fence?’ I asked. A ghost fence was a line of skulls, charmed by a Druid, across which no one would dare trespass.
Merlin stared at me as though my wits were gone. ‘A ghost fence! On Samain Eve! It is the one night of the year, halfwit, on which ghost fences do not work! Do I have to explain everything to you? A ghost fence, fool, works because it harnesses the souls of the dead to frighten the living, but on Samain Eve the souls of the dead are freed to wander and so cannot be harnessed. On Samain Eve a ghost fence is about as much use to the world as your wits.’
I took his reproof calmly. ‘I just hope you don’t get clouds,’ I said instead, trying to placate him.
‘Clouds?’ Merlin challenged me. ‘Why should clouds worry me? Oh, I see! That dimwit Gawain talked to you and he gets everything wrong. If it is cloudy, Derfel, the Gods will still see our signal because their sight, unlike ours, is not constrained by clouds, but if it is too cloudy then it is likely to rain, he made his voice into that of a man explaining something very simple to a small child, ‘and heavy rain will put out all the big fires. There, that was really difficult for you to work out for yourself, wasn’t it?’ He glared angrily at me, then turned away to stare at the rings of firewood. He leaned on his black staff, brooding at the huge thing he had done on Mai Dun’s summit. He was silent for a long time, then suddenly shrugged. ‘Have you ever thought,’ he asked, ‘what might have happened if the Christians had succeeded in putting Lancelot on the throne?’ His anger had gone, to be replaced by a melancholy.
‘No, Lord,’ I said.
‘Their year 500 would have come and they would all have been waiting for that absurd nailed God of theirs to come in glory.’ Merlin had been gazing at the rings as he spoke, but now he turned to look at me. ‘What if he had never come?’ he asked in puzzlement. ‘Suppose the Christians were all ready, all in their best cloaks, all washed and scrubbed and praying, and then nothing happened?’
‘Then in the year 501,’ I said, ‘there would be no Christians.’
Merlin shook his head. ‘I doubt that. It’s the business of priests to explain the inexplicable. Men like Sansum would have invented a reason, and people would believe them because they want to believe so very badly. Folk don’t give up hope because of disappointment, Derfel, they just redouble their hope. What fools we all are.’
‘So you’re frightened,’ I said, feeling a sudden stab of pity for him, ‘that nothing will happen at Samain?’
‘Of course I’m frightened, you halfwit. Nimue isn’t.’ He glanced at Nimue, who was watching us both with a sullen look. ‘You’re full of certainty, my little one, aren’t you?’ Merlin mocked her, ‘but as for me, Derfel, I wish this had never been necessary. We don’t even know what’s supposed to happen when we light the fires. Maybe the Gods will come, but perhaps they’ll bide their time?’ He gave me a fierce look.
‘If nothing happens, Derfel, that doesn’t mean that nothing happened. Do you understand that?’
‘I think so, Lord.’
‘I doubt you do. I don’t even know why I bother wasting explanations on you! Might as well lecture an ox on the finer points of rhetoric! Absurd man that you are. You can go now. You’ve delivered Excalibur.’
‘Arthur wants it back,’ I said, remembering to deliver Arthur’s message.
‘I’m sure he does, and maybe he will get it back when Gawain’s finished with it. Or maybe not. What does it matter? Stop worrying me with trifles, Derfel. And goodbye.’ He stalked off, angry again, but stopped after a few paces to turn and summon Nimue. ‘Come, girl!’
‘I shall make sure Derfel leaves,’ Nimue said, and with those words she took my elbow and steered me towards the inner rampart.
‘Nimue!’ Merlin shouted.
She ignored him, dragging me up the grass slope to where the path led along the rampart. I stared at the complex rings of firewood. ‘It’s a lot of work you’ve done,’ I said lamely.
‘And all wasted if we don’t perform the proper rituals,’ Nimue said waspishly. Merlin had been angry with me, but his anger was mostly feigned and it had come and gone like lightning, but Nimue’s rage was deep and forceful and had drawn her white, wedge-shaped face tight. She had never been beautiful, and the loss of her eye had given her face a dreadful cast, but there was a savagery and intelligence in her looks that made her memorable, and now, on that high rampart in the west wind, she seemed more formidable than ever.
