Even as Lewis said the magic word, the cold wind and the mountain disappeared and he felt a whirling, crushing feeling of blackness surround him. Just as he was beginning to wonder if it was ever going to stop, there was a sudden, warm surge of shimmering, comforting light. Tentatively, he opened his eyes, wondering where he had landed and what he might see. With magic, he thought worriedly, one just never knew. He hoped it wasn’t a goblin’s cave for a start. Of all the magic places he had visited in the past with Casimir, that had definitely been the worst.

The sight that met his eyes, however, was breathtaking in its beauty. He found himself staring in awe round the vast reaches of an elegant cavern whose lofty heights shone with a clear, blue-white light. A half circle of tall, silver thrones faced him and looking at the line-up of old, bearded figures that regarded him speculatively, he knew immediately where he was; for Prince Casimir had told him of the Court of the Lords of the North.

Feeling totally inadequate in old trainers, wet jeans and a scruffy anorak he walked towards the thrones and bowed so low that his head almost touched his knees.

“Welcome, Lewis,” a familiar voice said, kindly. “Welcome to the Court of the Lords of the North.”

Lewis straightened with a jerk, his eyes shining with relief and affection as Prince Casimir rose from one of the thrones and came towards him, resplendent in robes of dull red velvet.

“We are delighted to see you, Lewis,” Lady Ellan smiled as she came forward, followed by her husband. “You are most welcome.”

“Well, Lewis,” Lord Rothlan smiled understandingly. “Been getting up to mischief again, have you?”

Lewis almost blurted out the whole story there and then but experience had taught him to hold his tongue. He hadn’t yet been introduced to the Lords of the North and that must come first. Casimir was a real stickler for proper behaviour.

The Lords of the North were particularly affable to Lewis and treated him with great kindness. Firestar, in its own inimitable fashion, had communicated the result of its actions to them and they were still dizzy with relief that the attacking power had been destroyed. Indeed, they had just been marvelling at their escape when Lewis had landed so unexpectedly in their midst.

Lewis, mindful of the fact that Casimir missed nothing, bowed low as he was introduced to each of the lords and was ushered by Lord Alarid, himself, to a chair by the low table where a crystal ball rested on an ebony stand.

“Now, Lewis,” Prince Casimir said gravely as they took their seats round the table, “tell us your errand, for we know you wouldn’t have come here without good reason.”

Lewis, overawed despite himself, looked round the table at the expressions of polite enquiry on their faces. Lord Rothlan winked at him and, feeling heartened, he began his story. “Neil, Clara and I were in the next valley with Shona when … when there was a sort of explosion and the mountains all shook. You … you must have felt it …” he looked at them doubtfully. “This is Morven, isn’t it?”

Lord Rothlan nodded. “We did feel it, Lewis. And, yes, this is Morven. We’ll tell you what happened later. Go on with your story.”

“We saw a sort of bluish light shoot into the sky from Morven and as it fell back it seemed to spread over the whole area. I don’t know if it was because of the light but stone giants suddenly rose from all the slopes around us. They’re huge, twice as tall as houses, and we had to climb up the side of the mountain quickly to get out of their way. It was easy, though, for the magic dust seemed to have affected us as well — even Shona and she doesn’t have a firestone. We could take huge steps and jump over high boulders without any effort at all.”

The Lords of the North eyed one another anxiously. “The stone giants,” Lord Alarid looked guiltily at Casimir. “I didn’t know they had come so close to us.”

“Neil and the girls are stuck on the side of Ben Garchory,” Lewis added. “That’s why I came to you, Prince Casimir. The giants were all around us, knocking boulders and stuff from the sides of the mountains. We were trapped. And … well, that’s why I came; so that you could rescue them.”

Lord Alarid passed his hand over the glittering crystal and immediately the swirling mist cleared to show a huddled group of children crouched in a corrie near the top of the mountain. Then the view widened to reveal the length and breadth of Jennifer’s glen. Lady Ellan gave a gasp of astonishment and her husband sat up in alarm, for the glen was full of enormous giants.

Malfior felt their dismay but this time was unable to influence their minds for the giants were there, in front of them, on the edge of Glenmorven itself.

Lord Alarid looked at each of the old lords in turn and, as they nodded, chanted the words of a hex. “They will not be able to enter,” he said. “I have put a protective spell round the glen.”

“And the children?” queried Lady Ellan anxiously.

Again the lords looked at one another.

“We could bring Neil and Clara in right away,” Rothlan said, looking at Lewis enquiringly. “They are wearing their firestones, aren’t they?”

Lewis nodded. “Yes, but Shona isn’t.”

“Arthur, I think,” Casimir said thoughtfully. “The dragon will be able to stand up to the giants quite easily and the children can ride on his back.”

“Better leave Neil and Clara where they are then,” Lady Ellan said. “You’ll need someone there to reassure Shona, otherwise she’ll never go anywhere near Arthur.”

“It’s really urgent,” Lewis looked at Casimir anxiously, “and Edinburgh’s a long way away …”

Lord Alarid passed a hand over the crystal so that it once again glowed to life.

“It’s all right,” Casimir assured him as the MacArthur’s face appeared. “If Arthur uses a magic mirror, he can be here in seconds.”

Lewis nodded and tried not to look disbelieving. He knew exactly how big Arthur was and the thought of the dragon squeezing its huge bulk through a magic mirror was mind-boggling. That, however, was exactly what happened. Everyone turned as one of the magic mirrors started to ripple. Arthur’s head appeared followed by his neck, body, wings and tail, all of which expanded to their normal size in a burst of scarlet scales as he clawed his way through. The mirror rippled again as Archie and the MacArthur followed Arthur into the Great Hall and bowed low to the Lords of the North.
