Arya took Eragon’s hand then and drew him through the forest and toward the Menoa tree, where she said, “Look how the werelight dims. We have but a few hours left to us before dawn arrives and we must return to the world of cold reason.”

Around the tree, the host of elves gathered, their faces bright with eager anticipation. With great dignity, Islanzadí emerged from within their midst and walked along a root as wide as a pathway until it angled upward and doubled back on itself. She stood upon the gnarled shelf overlooking the slender, waiting elves. “As is our custom, and as was agreed upon at the end of The Dragon War by Queen Tarmunora, the first Eragon, and the white dragon who represented his race—he whose name cannot be uttered in this or any language—when they bound the fates of elves and dragons together, we have met to honor our blood-oath with song and dance and the fruits of our labor. Last this celebration occurred, many long years ago, our situation was desperate indeed. It has improved somewhat since, the result of our efforts, the dwarves’, and the Varden’s, though Alagaësia still lies under the black shadow of the Wyrdfell and we must still live with our shame of how we have failed the dragons.

“Of the Riders of eld, only Oromis and Glaedr remain. Brom and many others entered the void this past century. However, new hope has been granted to us in the form of Eragon and Saphira, and it is only right and proper that they should be here now, as we reaffirm the oath between our races three.”

At the queen’s signal, the elves cleared a wide expanse at the base of the Menoa tree. Around the perimeter, they staked a ring of lanterns mounted upon carved poles, while musicians with flutes, harps, and drums assembled along the ridge of one long root. Guided by Arya to the edge of the circle, Eragon found himself seated between her and Oromis, while Saphira and Glaedr crouched on either side of them like gem-studded bluffs.

To Eragon and Saphira, Oromis said, “Watch you carefully, for this is of great importance to your heritage as Riders.”

When all the elves were settled, two elf-maids walked to the center of the space in the host and stood with their backs to each other. They were exceedingly beautiful and identical in every respect, except for their hair: one had tresses as black as a forgotten pool, while the other’s hair gleamed like burnished silver wire.

“The Caretakers, Iduna and Nëya,” whispered Oromis.

From Islanzadí’s shoulder, Blagden shrieked,“Wyrda!”

Moving in unison, the two elves raised their hands to the brooches at their throats, unclasped them, and allowed their white robes to fall away. Though they wore no garments, the women were clad in an iridescent tattoo of a dragon. The tattoo began with the dragon’s tail wrapped around the left ankle of Iduna, continued up her leg and thigh, over her torso, and then across Nëya’s back, ending with the dragon’s head on Nëya’s chest. Every scale on the dragon was inked a different color; the vibrant hues gave the tattoo the appearance of a rainbow.

The elf-maids twined their hands and arms together so that the dragon appeared to be a continuous whole, rippling from one body to the next without interruption. Then they each lifted a bare foot and brought it down on the packed ground with a softthump.

And again:thump.

On the thirdthump, the musicians struck their drums in rhythm. Athump later, the harpists plucked the strings of their gilt instruments, and a moment after that, those elves with flutes joined the throbbing melody.

Slowly at first, but with gathering speed, Iduna and Nëya began to dance, marking time with the stamp of their feet on the dirt and undulating so that it was not they who seemed to move but the dragon upon them. Round and round they went, and the dragon flew endless circles across their skin.

Then the twins added their voices to the music, building upon the pounding beat with their fierce cries, their lyrics verses of a spell so complex that its meaning escaped Eragon. Like the rising wind that precedes a storm, the elves accompanied the incantation, singing with one tongue and one mind and one intent. Eragon did not know the words but found himself mouthing them along with the elves, swept along by the inexorable cadence. He heard Saphira and Glaedr hum in concordance, a deep pulse so strong that it vibrated within his bones and made his skin tingle and the air shimmer.

Faster and faster spun Iduna and Nëya until their feet were a dusty blur and their hair fanned about them and they glistened with a film of sweat. The elf-maids accelerated to an inhuman speed and the music climaxed in a frenzy of chanted phrases. Then a flare of light ran the length of the dragon tattoo, from head to tail, and the dragon stirred. At first Eragon thought his eyes had deceived him, until the creature blinked, raised his wings, and clenched his talons.

A burst of flame erupted from the dragon’s maw and he lunged forward and pulled himself free of the elves’ skin, climbing into the air, where he hovered, flapping his wings. The tip of his tail remained connected to the twins below, like a glowing umbilical cord. The giant beast strained toward the black moon and loosed an untamed roar of ages past, then turned and surveyed the assembled elves.

As the dragon’s baleful eye fell upon him, Eragon knew that the creature was no mere apparition but a conscious being bound and sustained by magic. Saphira and Glaedr’s humming grew ever louder until it blocked all other sound from Eragon’s ears. Above, the specter of their race looped down over the elves, brushing them with an insubstantial wing. It came to a stop before Eragon, engulfing him in an endless, whirling gaze. Bidden by some instinct, Eragon raised his right hand, his palm tingling.
