“Eka elrun ono,” he murmured to her.

Also in the ancient language, she said, “Be careful, Eragon. I would not want to see you broken by Murtagh. I . . .” It seemed as if she were going to say more, but she hesitated, then removed her hand from his leg and retreated to stand by Blödhgarm.

“Fly well, Bjartskular!” the elves sang out as Saphira launched herself off the embankment.

As Saphira winged her way toward Thorn, Eragon joined his mind first with her and then with Arya and, through Arya, with Blödhgarm and the eleven other elves. By having Arya serve as the focal point for the elves, Eragon was able to concentrate on the thoughts of Arya and Saphira; he knew them so well that their reactions would not distract him in the middle of a fight.

Eragon grasped the shield with his left hand and unsheathed his falchion, holding it upraised so he would not accidentally stab Saphira’s wings as she flapped, nor slash her shoulders nor her neck, which were in constant motion. I’m glad I took the time last night to reinforce the falchion with magic, he said to Saphira and Arya.

Let us hope your spells hold, Saphira answered.

Remember, said Arya, remain as close to us as you can. The more distance you place between us, the harder it is for us to maintain this bond with you.

Thorn did not dive at Saphira or otherwise attack her as she neared him, but rather slid away on rigid wings, allowing her to rise to his level unmolested. The two dragons balanced upon the thermals, facing each other across a gap of fifty yards, the tips of their barbed tails twitching, both of their muzzles wrinkled with ferocious snarls.

He’s bigger, observed Saphira. It’s not been two weeks since we last fought and he has grown another four feet, if not more.

She was right. Thorn was longer from head to tail, and deeper in the chest, than he had been when they first clashed over the Burning Plains. He was barely older than a hatchling, but he was already nearly as large as Saphira.

Eragon reluctantly shifted his gaze from the dragon to the Rider.

Murtagh was bareheaded, and his long black hair billowed behind him like a sleek mane. His face was hard, harder than Eragon had ever seen before, and Eragon knew that this time Murtagh would not, could not, show him mercy. The volume of his voice substantially reduced, but still louder than normal, Murtagh said, “You and Saphira have caused us a great deal of pain, Eragon. Galbatorix was furious with us for letting you go. And after the two of you killed the Ra’zac, he was so angry, he slew five of his servants and then turned his wrath upon Thorn and me. We have both suffered horribly on account of you. We shall not do so again.” He drew back his arm, as if Thorn were about to lunge forward and Murtagh were preparing to slash at Eragon and Saphira.

“Wait!” cried Eragon. “I know of a way you can both free yourselves of your oaths to Galbatorix.”

An expression of desperate longing transformed Murtagh’s features, and he lowered Zar’roc a few inches. Then he scowled and spat toward the ground and shouted, “I don’t believe you! It’s not possible!”

“It is! Just let me explain.”

Murtagh seemed to be struggling with himself, and for a while Eragon thought he might refuse. Swinging his head around, Thorn looked back at Murtagh, and something passed between them. “Blast you, Eragon,” said Murtagh, and lay Zar’roc across the front of his saddle. “Blast you for baiting us with this. We had already made peace with our lot, and you have to tantalize us with the specter of a hope we had abandoned. If this proves to be a false hope, brother, I swear I’ll cut off your right hand before we present you to Galbatorix. . . . You won’t need it for what you will be doing in Urû’baen.”

A threat of his own occurred to Eragon, but he suppressed it. Lowering the falchion, he said, “Galbatorix would not have told you, but when I was among the elves—”

Eragon, do not reveal anything more about us! exclaimed Arya.

“—I learned that if your personality changes, so does your true name in the ancient language. Who you are isn’t cast in iron, Murtagh! If you and Thorn can change something about yourselves, your oaths will no longer bind you, and Galbatorix will lose his hold on you.”

Thorn drifted several yards closer to Saphira. “Why didn’t you mention this before?” Murtagh demanded.

“I was too confused at the time.”

A scant fifty feet separated Thorn and Saphira by then. The red dragon’s snarl had subsided to a faint warning curl of his upper lip, and in his sparkling crimson eyes appeared a vast, puzzled sadness, as if he hoped Saphira or Eragon might know why he had been brought into the world merely so Galbatorix could enslave him, abuse him, and force him to destroy other beings’ lives. The tip of Thorn’s nose twitched as he sniffed at Saphira. She sniffed him in return, and her tongue darted out of her mouth as she tasted his scent. Pity for Thorn welled up inside Eragon and Saphira together, and they wished they could speak with him directly, but they dared not open their minds to him.

With so little distance between them, Eragon noticed the bundles of cords that ridged Murtagh’s neck and the forked vein that pulsed in the middle of his forehead.

“I am not evil!” said Murtagh. “I’ve done the best I could under the circumstances. I doubt you would have survived as well as I did if our mother had seen fit to leave you in Urû’baen and hide me in Carvahall.”

“Perhaps not.”

Murtagh banged his breastplate with his fist. “Aha! Then how am I supposed to follow your advice? If I am already a good man, if I have already done as well as could be expected, how can I change? Must I become worse than I am? Must I embrace Galbatorix’s darkness in order to free myself of it? That hardly seems like a reasonable solution. If I succeeded in so altering my identity, you would not like who I had become, and you would curse me as strongly as you curse Galbatorix now.”
