His skin tingling, Eragon severed his link with the gem. Delighted by his discovery and his sudden sense of well-being, he laughed out loud, then told Arya what he had found. “Brom must have squirreled away every bit of energy he could spare the whole time he was hiding in Carvahall.” He laughed again, marveling. “All those years . . . With what’s in Aren, I could tear apart an entire castle with a single spell.”

“He knew he would need it to keep the new Rider safe when Saphira hatched,” observed Arya. “Also, I am sure Aren was a way for him to protect himself if he had to fight a Shade or some other similarly powerful opponent. It was not by accident that he managed to frustrate his enemies for the better part of a century. . . . If I were you, I would save the energy he left you for your hour of greatest need, and I would add to it whenever I could. It is an incredibly valuable resource. You should not squander it.”

No, thought Eragon, that I will not. He twirled the ring around his finger, admiring how it gleamed in the firelight. Since Murtagh stole Zar’roc, this, Saphira’s saddle, and Snowfire are the only things I have of Brom, and even though the dwarves brought Snowfire from Farthen Dûr, I rarely ride him nowadays. Aren is really all I have to remember him by. . . . My only legacy of him. My only inheritance. I wish he were still alive! I never had a chance to talk with him about Oromis, Murtagh, my father. . . . Oh, the list is endless. What would he have said about my feelings for Arya? Eragon snorted to himself. I know what he would have said: he would have berated me for being a love-struck fool and for wasting my energy on a hopeless cause. . . . And he would have been right too, I suppose, but, ah, how can I help it? She is the only woman I wish to be with.

The fire cracked. A flurry of sparks flew upward. Eragon watched with half-closed eyes, contemplating Arya’s revelations. Then his mind returned to a question that had been bothering him ever since the battle on the Burning Plains. “Arya, do male dragons grow any faster than female dragons?”

“No. Why do you ask?”

“Because of Thorn. He’s only a few months old, and yet he’s already nearly as big as Saphira. I don’t understand it.”

Picking a dry blade of grass, Arya began sketching in the loose soil, tracing the curved shapes of glyphs from the elves’ script, the Liduen Kvaedhí. “Most likely Galbatorix accelerated his growth so Thorn would be large enough to hold his own with Saphira.”

“Ah. . . . Isn’t that dangerous, though? Oromis told me that if he used magic to give me the strength, speed, endurance, and other skills I needed, I would not understand my new abilities as well as if I had gained them the ordinary way: by hard work. He was right too. Even now, the changes the dragons made to my body during the Agaetí Blödhren still sometimes catch me by surprise.”

Arya nodded and continued sketching glyphs in the dirt. “It is possible to reduce the undesirable side effects by certain spells, but it is a long and arduous process. If you wish to achieve true mastery of your body, it is still best to do so through normal means. The transformation Galbatorix has forced upon Thorn must be incredibly confusing for him. Thorn now has the body of a nearly grown dragon, and yet his mind is still that of a youngling.”

Eragon fingered the newly formed calluses on his knuckles. “Do you also know why Murtagh is so powerful . . . more powerful than I am?”

“If I did, no doubt I would also understand how Galbatorix has managed to increase his own strength to such unnatural heights, but alas, I do not.”

But Oromis does, Eragon thought. Or at least the elf had hinted as much. However, he had yet to share the information with Eragon and Saphira. As soon as they were able to return to Du Weldenvarden, Eragon intended to ask the elder Rider for the truth of the matter. He has to tell us now! Because of our ignorance, Murtagh defeated us, and he could have easily taken us to Galbatorix. Eragon almost mentioned Oromis’s comments to Arya but held his tongue, for he realized that Oromis would not have concealed such an important fact for over a hundred years unless secrecy was of the utmost importance.

Arya signed a stop to the sentence she had been writing on the ground. Bending over, Eragon read, Adrift upon the sea of time, the lonely god wanders from shore to distant shore, upholding the laws of the stars above.

“What does it mean?”

“I don’t know,” she said, and smoothed out the line with a sweep of her arm.

“Why is it,” he asked, speaking slowly as he organized his thoughts, “that no one ever refers to the dragons of the Forsworn by name? We say ‘Morzan’s dragon’ or ‘Kialandí’s dragon,’ but we never actually name the dragon. Surely they were as important as their Riders! I don’t even remember seeing their names in the scrolls Oromis gave me . . . although they must have been there. . . . Yes, I’m certain they were, but for some reason, they don’t stick in my head. Isn’t that strange?” Arya started to answer, but before she could do more than open her mouth, he said, “For once I’m glad Saphira’s not here. I’m ashamed I haven’t noticed this before. Even you, Arya, and Oromis and every other elf I’ve met refuse to call them by name, as if they were dumb animals, undeserving of the honor. Do you do it on purpose? Is it because they were your enemies?”

“Did none of your lessons speak of this?” asked Arya. She seemed genuinely surprised.

“I think,” he said, “Glaedr mentioned something about it to Saphira, but I’m not exactly sure. I was in the middle of a backbend during the Dance of Snake and Crane, so I wasn’t really paying attention to what Saphira was doing.” He laughed a little, embarrassed by his lapse and feeling as if he had to explain himself. “It got confusing at times. Oromis would be talking to me while I was listening to Saphira’s thoughts while she and Glaedr communicated with their minds. What’s worse, Glaedr rarely uses a recognizable language with Saphira; he tends to use images, smells, and feelings, rather than words. Instead of names, he sends impressions of the people and objects he means.”
