A fan of golden light flared into existence as the top of the sun crested the horizon. In an instant, the full spectrum of colors enlivened the previously drab world: the mist glowed white, the water became a rich blue, the daubed-mud wall that encircled the center of Dras-Leona revealed its dingy yellow sides, the trees cloaked themselves in every shade of green, and the soil blushed red and orange. Helgrind, however, remained as it always was—black.

The mountain of stone rapidly grew larger as they approached. Even from the air, it was intimidating.

Diving toward the base of Helgrind, Saphira tilted so far to her left, Eragon and Roran would have fallen if they had not already strapped their legs to the saddle. Then she whipped around the apron of scree and over the altar where the priests of Helgrind observed their ceremonies. The lip of Eragon’s helm caught the wind from her passage and produced a howl that almost deafened him.

“Well?” shouted Roran. He could not see in front of them.

“The slaves are gone!”

A great weight seemed to press Eragon into his seat as Saphira pulled out of her dive and spiraled up around Helgrind, searching for an entrance to the Ra’zac’s hideout.

Not even a hole big enough for a woodrat, she declared. She slowed and hung in place before a ridge that connected the third lowest of the four peaks to the prominence above. The jagged buttress magnified the boom produced by each stroke of her wings until it was as loud as a thunderclap. Eragon’s eyes watered as the air pulsed against his skin.

A web of white veins adorned the backside of the crags and pillars, where hoarfrost had collected in the cracks that furrowed the rock. Nothing else disturbed the gloom of Helgrind’s inky, windswept ramparts. No trees grew among the slanting stones, nor shrubs, grass, or lichen, nor did eagles dare nest upon the tower’s broken ledges. True to its name, Helgrind was a place of death, and stood cloaked in the razor-sharp, sawtooth folds of its scarps and clefts like a bony specter risen to haunt the earth.

Casting his mind outward, Eragon confirmed the presence of the two people whom he had discovered imprisoned within Helgrind the previous day, but he felt nothing of the slaves, and to his concern, he still could not locate the Ra’zac or the Lethrblaka. If they aren’t here, then where? he wondered. Searching again, he noticed something that had eluded him before: a single flower, a gentian, blooming not fifty feet in front of them, where, by all rights, there ought to be solid rock. How does it get enough light to live?

Saphira answered his question by perching on a crumbling spur several feet to the right. As she did, she lost her balance for a moment and flared her wings to steady herself. Instead of brushing against the bulk of Helgrind, the tip of her right wing dipped into the rock and then back out again.

Saphira, did you see that!

I did.

Leaning forward, Saphira pushed the tip of her snout toward the sheer rock, paused an inch or two away—as if waiting for a trap to spring—then continued her advance. Scale by scale, Saphira’s head slid into Helgrind, until all that was visible of her to Eragon was a neck, torso, and wings.

It’s an illusion! exclaimed Saphira.

With a surge of her mighty thews, she abandoned the spur and flung the rest of her body after her head. It required every bit of Eragon’s self-control not to cover his face in a desperate bid to protect himself as the crag rushed toward him.

An instant later, he found himself looking at a broad, vaulted cave suffused with the warm glow of morning. Saphira’s scales refracted the light, casting thousands of shifting blue flecks across the rock. Twisting around, Eragon saw no wall behind them, only the mouth of the cave and a sweeping view of the landscape beyond.

Eragon grimaced. It had never occurred to him that Galbatorix might have hidden the Ra’zac’s lair with magic. Idiot! I have to do better, he thought. Underestimating the king was a sure way to get them all killed.

Roran swore and said, “Warn me before you do something like that again.”

Hunching forward, Eragon began to unbuckle his legs from the saddle as he studied their surroundings, alert for danger.

The opening to the cave was an irregular oval, perhaps fifty feet high and sixty feet wide. From there the chamber expanded to twice that size before ending a good bowshot away in a pile of thick stone slabs that leaned against each other in a confusion of uncertain angles. A mat of scratches defaced the floor, evidence of the many times the Lethrblaka had taken off from, landed on, and walked about its surface. Like mysterious keyholes, five low tunnels pierced the sides of the cave, as did a lancet passageway large enough to accommodate Saphira. Eragon examined the tunnels carefully, but they were pitch-black and appeared vacant, a fact he confirmed with quick thrusts of his mind. Strange, disjointed murmurs echoed from within Helgrind’s innards, suggesting unknown things scurrying about in the dark, and endlessly dripping water. Adding to the chorus of whispers was the steady rise and fall of Saphira’s breathing, which was overloud in the confines of the bare chamber.

The most distinctive feature of the cavern, however, was the mixture of odors that pervaded it. The smell of cold stone dominated, but underneath Eragon discerned whiffs of damp and mold and something far worse: the sickly sweet fetor of rotting meat.

Undoing the last few straps, Eragon swung his right leg over Saphira’s spine, so he was sitting sidesaddle, and prepared to jump off her back. Roran did the same on the opposite side.

Before he released his hold, Eragon heard, amid the many rustlings that teased his ear, a score of simultaneous clicks, as if someone had struck the rock with a collection of hammers. The sound repeated itself a half second later.
