At last Eragon felt a hint of warm air rising toward them from farther down the tunnel, and he noticed a faint orange glow in the distance. “Letta,” he murmured, and extinguished the werelight.

The air continued to warm as they descended, and the glow before them waxed in brightness. Soon they were able to see an end to the tunnel: a huge black arch that was covered entirely with sculpted glyphs, which made the arch look as if it were wrapped in thorns. The smell of brimstone tainted the air, and Eragon felt his eyes begin to water.

They stopped before the archway; through it, all they could see was a flat gray floor.

Eragon glanced back the way they had come, then returned his gaze to the arch. The jagged structure made him nervous, and Saphira as well. He tried to read the glyphs, but they were too jumbled and too densely packed to make sense of, nor could he detect any energy stored within the black structure. Yet he had difficulty believing that it was not enchanted. Whoever built the tunnel had succeeded in hiding the latch spell for the doors to the outside, which meant they could have done the same with any spells they had placed upon the arch.

He exchanged a quick look with Saphira, and he wet his lips as he remembered what Glaedr had said: There are no more safe paths.

Saphira snorted, releasing a small jet of flame from the pit of each nostril, and then, as one, she and Eragon walked through the archway.

LACUNA, PART THE FIRST

ragon noticed several things at once.

First, that they were standing at one side of a circular chamber over two hundred feet across with a large pit in the center, from which radiated a dull orange glow. Second, that the air was stiflingly hot. Third, that around the outer part of the room were two concentric rings of benchlike tiers—the back one higher than the front—upon which rested numerous dark objects. Fourth, that the wall behind this tier sparkled in numerous places, as if decorated with colored crystal. But he had no opportunity to examine either the wall or the dark objects, for in the open area next to the glowing pit there stood a man with the head of a dragon.

The man was made of metal, and he gleamed like polished steel. He wore no clothes other than a segmented loincloth fashioned out of the same lustrous material as his body, and his chest and limbs rippled with muscles like those of a Kull. In his left hand, he held a metal shield, and in his right, an iridescent sword that Eragon recognized as the blade of a Rider.

Behind the man, set within the far side of the room, Eragon vaguely saw a throne with the outline of the creature’s body worn into its back and seat.

The dragon-headed man strode forward. His skin and joints moved as smoothly as flesh, but every step sounded as if a great weight was being dropped onto the floor. He stopped thirty feet from Eragon and Saphira and stared at them with eyes that flickered like a pair of crimson flames. Then, lifting his scaled head, he uttered a peculiar metallic roar that echoed until it seemed as if a dozen creatures were bellowing at them.

Even as Eragon was wondering whether they were supposed to fight the creature, he felt a strange, vast mind touch his. The consciousness was unlike any he had encountered before, and it seemed to contain a host of shouting voices, a great, disjointed chorus that reminded him of the wind inside a storm.

Before he could react, the mind stabbed through his defenses and seized control of his thoughts. For all the time he had spent practicing with Glaedr, Arya, and Saphira, he could not stop the attack; he could not even slow it. He might as well have tried to hold back the tide with his bare hands.

A blur of light and a roar of incoherent noise surrounded him as the yammering chorus forced itself into every nook and cranny of his being. Then it felt as if the invader tore his mind into a half-dozen pieces—each of which remained aware of the others, but none of which was free to do as it wished—and his vision fragmented, as if he were seeing the chamber through the facets of a jewel.

Six different memories began to race through his fractured consciousness. He had not chosen to recall them; they simply appeared, and they flew past faster than he could follow. At the same time, his body bent and flexed in various poses, and then his arm lifted Brisingr to where his eyes could see, and he beheld six identical versions of the sword. The invader even had him cast a spell, the purpose of which he did not and could not understand, for the only thoughts he had were those the other allowed. Nor did he feel any emotion but that of fading alarm.

For what seemed like hours, the alien mind examined every one of his memories, from the moment he had set out from his family’s farm to hunt deer in the Spine—three days before he had found Saphira’s egg—up until the present. In the back of his mind, Eragon could sense the same thing happening to Saphira, but the knowledge meant nothing to him.

At last, long after he would have given up hope of release if he still had command of his thoughts, the whirling chorus carefully rejoined the pieces of his mind and then withdrew.

Eragon staggered forward and dropped to one knee before he was able to regain his balance. Beside him, Saphira lurched and snapped at the air.

How? he thought. Who? To capture both of them at once, and Glaedr as well, he assumed, was something he did not believe even Galbatorix was capable of.

Again the consciousness pressed against Eragon’s mind, but this time it did not attack. This time it said, Our apologies, Saphira. Our apologies, Eragon, but we had to be certain of your intentions. Welcome to the Vault of Souls. Long have we waited for you. And welcome to you as well, cousin. We are glad that you are still alive. Take now your memories, and know that your task is at long last complete!
