“Eragon! Clear your mind!” He struggled in a futile attempt to break her grip. “Eyddr eyreya onr!” Empty your ears! Everything fell silent then, as if he had gone deaf. He stopped fighting and looked around, wondering what had just occurred. On the other side of the fire, Lifaen and Narí wrestled noiselessly with Orik.

Eragon watched Arya’s mouth move as she spoke, then sound returned to the world with apop, though he could no longer hear the music. “What . . . ?” he asked, dazed.

“Gerr’off me,” growled Orik. Lifaen and Narí lifted their hands and backed away.

“Your pardon, Orik-vodhr,” said Lifaen.

Arya gazed toward Sílthrim. “I miscounted the days; I didn’t want to be anywhere near a city during Dagshelgr. Our saturnalias, our celebrations, are perilous for mortals. We sing in the ancient language, and the lyrics weave spells of passion and longing that are difficult to resist, even for us.”

Narí stirred restlessly. “We should be at a grove.”

“We should,” agreed Arya, “but we will do our duty and wait.”

Shaken, Eragon sat closer to the fire, wishing for Saphira; he was sure she could have protected his mind from the music’s influence. “What is the point of Dagshelgr?” he asked.

Arya joined him on the ground, crossing her long legs. “It is to keep the forest healthy and fertile. Every spring we sing for the trees, we sing for the plants, and we sing for the animals. Without us, Du Weldenvarden would be half its size.” As if to emphasize her point, birds, deer, squirrels—red and gray—striped badgers, foxes, rabbits, wolves, frogs, toads, tortoises, and every other nearby animal forsook their hiding and began to rush madly about with a cacophony of yelps and cries. “They are searching for mates,” explained Arya. “All across Du Weldenvarden, in each of our cities, elves are singing this song. The more who participate, the stronger the spell, and the greater Du Weldenvarden will be this year.”

Eragon snatched back his hand as a trio of hedgehogs trundled past his thigh. The entire forest yammered with noise.I’ve stepped into fairyland, he thought, hugging himself.

Orik came around the fire and raised his voice above the clamor: “By my beard and my ax, I’ll not be controlled against my will by magic. If it happens again, Arya, I swear on Helzvog’s stone girdle that I’ll return to Farthen Dûr and you will have the wrath of Dûrgrimst Ingeitum to deal with.”

“It was not my intention for you to experience Dagshelgr,” said Arya. “I apologize for my mistake. However, though I am shielding you from this spell, you cannot escape magic in Du Weldenvarden; it permeates everything.”

“So long as it doesn’t befoul my mind.” Orik shook his head and fingered the haft of his ax while eyeing the shadowy beasts that lumbered in the gloom beyond the pool of firelight.

No one slept that night. Eragon and Orik remained awake because of the frightful din and the animals that kept crashing by their tents, the elves because they still listened to the song. Lifaen and Narí took to pacing in endless circles, while Arya stared toward Sílthrim with a hungry expression, her tawny skin drawn thin and taut over her cheekbones.

Four hours into the riot of sound and motion, Saphira dove out of the sky, her eyes sparkling with a queer aspect. She shivered and arched her neck, panting between her open jaws.The forest, she said,is alive. And I am alive. My blood burns like never before. It burns as yours burns when you think of Arya. I . . . understand!

Eragon put his hand on her shoulder, feeling the tremors that racked her frame; her sides vibrated as she hummed along with the music. She gripped the ground with her ivory claws, her muscles coiled and clenched in a supreme effort to remain motionless. The tip of her tail twitched like she was about to pounce.

Arya stood and joined Eragon on the opposite side of Saphira. The elf also put a hand on Saphira’s shoulder, and the three of them faced the darkness, united into a living chain.

When dawn broke, the first thing Eragon noticed was that all the trees now had buds of bright green needles at the ends of their branches. He bent and examined the snowberries at his feet and found that every plant, large or small, had acquired new growth during the night. The forest vibrated with the ripeness of its colors; everything was lush and fresh and clean. The air smelled like it had just rained.

Saphira shook herself beside Eragon and said,The fever has passed; I am myself again. Such things I felt. . . It was as if the world were being born anew and I was helping to create it with the fire in my limbs.

How are you? On the inside, I mean.

I will need some time to understand what I experienced.

Since the music had ceased, Arya removed her spell from Eragon and Orik. She said, “Lifaen. Narí. Go to Sílthrim and get horses for the five of us. We cannot walk all the way from here to Ellesméra. Also, alert Captain Damítha that Ceris requires reinforcements.”

Narí bowed. “And what shall we say when she asks why we have deserted our post?”

“Tell her that that which she once hoped for—and feared—has occurred; the wyrm has bitten its own tail. She will understand.”

The two elves departed for Sílthrim after the boats were emptied of supplies. Three hours later, Eragon heard a stick snap and looked up to see them returning through the forest on proud white stallions, leading four other identical horses. The magnificent beasts moved among the trees with uncanny stealth, their coats shimmering in the emerald twilight. None of them wore saddles or harnesses.
