“By all the demons above and below, how many oaths have you and Saphira sworn?” demanded Nasuada. “You seem to bind yourself to everyone you meet.”

Feeling somewhat sheepish, Eragon shrugged and had opened his mouth to speak when Saphira said to Nasuada, We do not seek them out, but how can we avoid pledging ourselves when we cannot topple Galbatorix and the Empire without the support of every race in Alagaësia? Oaths are the price we pay for winning the aid of those in power.

“Mmh,” said Nasuada. “So I must ask Arya for the truth of the matter?”

“Aye, but I doubt she will tell you; the elves consider the identity of our teachers to be one of their most precious secrets. They will not risk sharing it unless absolutely necessary, to keep word of it from reaching Galbatorix.” Eragon stared at the royal-blue gemstone set in his ring, wondering how much more information his oath and his honor would allow him to divulge, then said, “Know this, though: we are not so alone as we once assumed.”

Nasuada’s expression sharpened. “I see. That is good to know, Eragon. . . . I only wish the elves were more forthcoming with me.” After pursing her lips for a brief moment, Nasuada continued. “Why must you travel all the way to Ellesméra? Have you no means to communicate with your tutors directly?”

Eragon spread his hands in a gesture of helplessness. “If only we could. Alas, the spell has yet to be invented that can broach the wards that encircle Du Weldenvarden.”

“The elves did not even leave an opening they themselves can exploit?”

“If they had, Arya would have contacted Queen Islanzadí as soon as she was revived in Farthen Dûr, rather than physically going to Du Weldenvarden.”

“I suppose you are right. But then how was it you were able to consult Islanzadí about Sloan’s fate? You implied that when you spoke with her, the elves’ army was still situated within Du Weldenvarden.”

“They were,” he said, “but only in the fringe, beyond the protective measures of the wards.”

The silence between them was palpable as Nasuada considered his request. Outside the tent, Eragon heard the Nighthawks arguing among themselves about whether a bill or a halberd was better suited for fighting large numbers of men on foot and, beyond them, the creak of a passing oxcart, the jangle of armor on men trotting in the opposite direction, and hundreds of other indistinct sounds that drifted through the camp.

When Nasuada spoke, she said, “What exactly do you hope to gain from such a visit?”

“I don’t know!” growled Eragon. He struck the pommel of the falchion with his fist. “And that’s the heart of the problem: we don’t know enough. It might accomplish nothing, but on the other hand, we might learn something that could help us vanquish Murtagh and Galbatorix once and for all. We barely won yesterday, Nasuada. Barely! And I fear that when we again face Thorn and Murtagh, Murtagh will be even stronger than before, and frost coats my bones when I consider the fact that Galbatorix’s abilities far exceed Murtagh’s, despite the vast amount of power he has already bestowed upon my brother. The elf who taught me, he . . .” Eragon hesitated, considering the wisdom of what he was about to say, then forged onward: “He hinted that he knows how it is Galbatorix’s strength has been increasing every year, but he refused to reveal more at the time because we were not advanced enough in our training. Now, after our encounters with Thorn and Murtagh, I think he will share his knowledge with us. Moreover, there are entire branches of magic we have yet to explore, and any one of them might provide the means to defeat Galbatorix. If we are going to gamble upon this trip, Nasuada, then let us not gamble to maintain our current position; let us gamble to increase our standing and so win this game of chance.”

Nasuada sat motionless for over a minute. “I cannot make this decision until after the dwarves hold their coronation. Whether you go to Du Weldenvarden will depend on the movements of the Empire then and on what our spies report about Murtagh and Thorn’s activities.”

Over the course of the next two hours, Nasuada instructed Eragon about the thirteen dwarf clans. She schooled him in their history and their politics; in the products upon which each clan based the majority of its trade; in the names, families, and personalities of the clan chiefs; in the list of important tunnels excavated and controlled by each clan; and in what she felt would be the best way to coax the dwarves to elect a king or queen friendly to the goals of the Varden.

“Ideally, Orik would be the one to take the throne,” she said. “King Hrothgar was highly regarded by most of his subjects, and Dûrgrimst Ingeitum remains one of the richest and most influential of clans, all of which is to Orik’s benefit. Orik is devoted to our cause. He has served as one of the Varden, you and I both count him as a friend, and he is your foster brother. I believe he has the skills to become an excellent king for the dwarves.” Amusement kindled in her expression. “Small matter, that. However, he is young by the standards of the dwarves, and his association with us may prove to be an insurmountable barrier for the other clan chiefs. Another obstacle is that the other great clans—Dûrgrimst Feldûnost and Dûrgrimst Knurlcarathn, to name but two—are eager, after over a hundred years of rule by the Ingeitum, to see the crown go to a different clan. By all means, support Orik if it can help him onto the throne, but if it becomes obvious that his attempt is doomed and your backing could guarantee the success of another clan chief who favors the Varden, then transfer your support, even if doing so will offend Orik. You cannot allow friendship to interfere with politics, not now.”
