I turned and asked sharply. 'If Charis is in Ynys Avallach, who rules in Dyfed?'

'Lord Tewdrig – a nephew of Maelwys.'

'And in the Summerlands?'

'A lord named Elyvar,' replied Pelleas, and added hesitantly, as if breaking bad news, 'but there is another over him – called Vortigern. Indeed, this… this man – he has set himself as king over all the lords of Britain.'

'A High King.' Oh, Vortigern, yes. I have seen your face in the fire; I have seen the shadow of your coming. Yes, and I have heard the thunder of your fall.

'What is it, my lord?'

'It is nothing, Pelleas. Vortigern rules in the Summerlands, you were saying?'

'In Gwynedd, Rheged, and Lloegres as well. He is a most ambitious man, lord, and most ruthless. He stops at nothing to win his way.'

'I know about him, Pelleas. But do not worry, his days are not long in the land.'

'Lord?'

'It is something I have seen, Pelleas.' I turned my eyes to look down into the valley where the dark folds of the trees gathered around the feet of the mountain. Four riders were making their way towards us along the banks of the stream.

I should have been surprised – especially after all these years alone – but part of me expected them, I think, for upon seeing them I knew who they were and why they had come. I knew also who had led them to me.

'The enemy has wasted no time,' I said, remembering my first visitor and his subtle guile. Well, I had not been tricked – sick in heart and mind as I was, by the Good God's grace I was not tricked. And now I was insane no longer. I was healed and whole again.

Ancient Enemy, do your worst! I, Myrddin Emrys, defy you!

Pelleas watched the riders approach for a moment. 'Perhaps we should leave now, master.'

'No,' I told him. 'You ask where we will go. I think these men have come to escort us on our way.'

'Where?'

'To see a wonder in the land – the man who has made himself a king higher than any other since kingship began in this island.'

'Vortigern's men! I was not followed, Lord Myrddin, I swear it!'

'No, you were not followed. They were sent by another.'

'We still have time – let us flee.'

'Why, Pelleas, we have nothing to fear from these men. Besides, I would like to meet this Vortigern face to face. I have never seen a High King before.'

Pelleas made a face. 'He is not much to look at, I am told. And those who value their lives and land stay as far away from him as possible.'

'Nevertheless, I will go and pay my respects to the man who has held the island in my stead.'

We waited while the riders toiled slowly up the steep slope, and it gave me time to observe them closely. They were three stout fighting men with bronze armbands and oxhide shields, and another, darker man who, judging by the oak staff behind his saddle, was a druid. Though it was early morning, all appeared worn and travel weary, their horses drooping with exhaustion. Their errand was an important one, I gathered; they had not lingered on the way, but had driven themselves hard to find me.

When they were close enough, I greeted them and called them to me. 'Hail, travellers, the Forest Lord welcomes you!'

They reined up at this and then sat looking at one another for a moment, muttering under their breath. 'Who are you?' the foremost rider, the druid, asked curtly.

"That you already know, for I have told you. I might well ask who you are, but I am not in the habit of asking questions when the answer is known to me.'

'You know who we are?' asked one of the others, coming a few cautious steps closer.

'I do,' I assured him.

'Then maybe you also know why we have come.' He cast a disapproving glance at Pelleas beside me, as if Pelleas had spoiled their secret.

'You have come to take me to meet your lord, one called Vortigern, who makes himself a king.' They did not like this answer, but it was true and they did not challenge my meaning for I spoke civilly enough.

'We have come,' replied the druid, 'to find one called Merlin Embries.'

'And you have found him,' I said. 'It is he that addresses you.'

The druid did not appear convinced. 'The man we seek was already old when I was a child. You cannot be Merlin.'

'Then indeed you do not know who it is you are searching for.'

He puzzled on that for a moment. 'They say Merlin is of the Fair Folk,' pointed out the rider beside him. 'That would explain it.'

'Your horses are tired, and you are nearly falling out of your saddles. Dismount; rest yourselves and your animals. Eat something and regain your strength for our journey back.'

This shocked them more than anything I had said so far. They had thought to take me by force; the notion that I might go willingly had never occurred to them.

'We mean to take you with us,' the second rider stubbornly warned me.

'Have I not already said that I will go? I desire to speak with your lord.'

The druid nodded and signalled the others to dismount. He swung himself down from the saddle and came to stand before me. 'Do not try to escape. I am a druid; I have power. Your tricks will not work on me.'

I laughed. 'I would speak lightly of power, friend, for I know whence your power comes. I tell you the truth, I have faced your lord and was not overcome. I will not be overcome by you. Darkness has no power over light, and no power on earth can move me if I do not wish to be moved. It is by my free choice alone that I go with you.'

He frowned and turned to the others, barking orders to unsaddle and water the beasts. 'We will rest here a while,' he said.

'Help them with the horses, Pelleas. I must say my farewells.' I turned and began walking back up the hill to my cave to find Wolf.

Well, Wolf was not to be left behind so easily. At first, I feared for the horses, but I need not have worried, for at the sight of her with me the animals took her for a dog and accepted her as they would any hunting hound. The men were not so easily persuaded.

'Get that killer away!' cried one of the riders, leaping to his feet, his dagger drawn and held out before him – although what protection that would have offered, I cannot imagine.

'Sit down,' I told him. 'Be silent. She will not harm you if you do not provoke her. And put that knife away; if she wanted your life, nothing would save you, least of all your sorry blade.'

The man stared at the golden eyes of the wolf, then at mine. He made the sign against evil with his left hand and muttered under his breath. I heard what he said, and told him, 'You have nothing to fear, Iddec.'

His fright did not leave him and he clutched the knife even tighter. 'How do you know me?' he rasped.

'I know a great many things,' I replied.

One of the other riders heard what I said and came closer, giving the wolf a wide respect. 'Then you know what we mean to do -' he began.

'Yes, Daned, I know.'

'Shut up!' shouted the druid. 'It is a trick! Tell him nothing!"

'He knows!,' shouted Daned. 'We cannot keep it from him.'

'He knows nothing unless you tell him!'

'He called me by name,' insisted Iddec. 'Both of us – he knew us both.'

The druid, Duach, flew at the warriors. 'He heard you talking among yourselves. You've probably named yourselves to him a hundred times since we first saw him.'

The two glanced at one another, unconvinced. Grumbling, they went back to unsaddling their horses. Duach turned on me. 'Leave them alone,' he said. 'They may be foolish enough to believe your lies; nevertheless, they will slit your throat right smart if I tell them to.'

Wolf beside me growled deep in her throat, and the druid stepped back. 'Get rid of that animal if you would save its life.'

'Do not raise your voice or hand against me again, Duach, if you would save yours.'

Pelleas had watched all this silently and now came close. 'I do not care for their manner, lord. Perhaps it is a mistake logo with them.'
