A current of air tickled Eragon’s skin, then paused and reversed itself as pressure from the outside waxed and waned. The cycle repeated itself at inconsistent intervals, creating invisible eddies that brushed against him like fountains of roiling water.

His breathing, and Roran’s, was loud and ragged compared with the odd assortment of sounds that propagated through the tunnel. Above the gusts of their respiration, Eragon caught the tink, clink, clatter of a stone falling somewhere in the tangle of branching tubes and the steady doink . . . doink . . . doink of condensed droplets striking the drumlike surface of a subterranean pool. He also heard the grind of pea-sized gravel crushed underneath the soles of his boots. A long, eerie moan wavered somewhere far ahead of them.

Of smells, none were new: sweat, blood, damp, and mold.

Step by step, Eragon led the way as they burrowed farther into the bowels of Helgrind. The tunnel slanted downward and often split or turned, so that Eragon would have soon been lost if he had not been able to use Katrina’s mind as a reference point. The various knobby holes were low and cramped. Once, when Eragon bumped his head against the ceiling, a sudden flare of claustro -phobia unnerved him.

I’m back, Saphira announced just as Eragon put his foot on a rugged step hewn out of the rock below him. He paused. She had escaped additional injury, which relieved him.

And the Lethrblaka?

Floating belly-up in Leona Lake. I’m afraid that some fishermen saw our battle. They were rowing toward Dras-Leona when I last saw them.

Well, it can’t be helped. See what you can find in the tunnel the Lethrblaka came out of. And keep an eye out for the Ra’zac. They may try to slip past us and escape Helgrind through the entrance we used.

They probably have a bolt-hole at ground level.

Probably, but I don’t think they’ll run quite yet.

After what seemed like an hour trapped in the darkness—though Eragon knew it could not have been more than ten or fifteen minutes—and after descending more than a hundred feet through Helgrind, Eragon stopped on a level patch of stone. Transmitting his thoughts to Roran, he said, Katrina’s cell is about fifty feet in front of us, on the right.

We can’t risk letting her out until the Ra’zac are dead or gone.

What if they won’t reveal themselves until we do let her out? For some reason, I can’t sense them. They could hide from me until doomsday in here. So do we wait for who knows how long, or do we free Katrina while we still have the chance? I can place some wards around her that should protect her from most attacks.

Roran was quiet for a second. Let’s free her, then.

They began to move forward again, feeling their way along the squat corridor with its rough, unfinished floor. Eragon had to devote most of his attention to his footing in order to maintain his balance.

As a result, he almost missed the swish of cloth sliding over cloth and then the faint twang that emanated from off to his right.

He recoiled against the wall, shoving Roran back. At the same time, something augered past his face, carving a groove of flesh from his right cheek. The thin trench burned as if cauterized.

“Kveykva!” shouted Eragon.

Red light, bright as the midday sun, flared into existence. It had no source, and thus it illuminated every surface evenly and without shadows, giving things a curious flat appearance. The sudden blaze dazzled Eragon, but it did more than that to the lone Ra’zac in front of him; the creature dropped its bow, covered its hooded face, and screamed high and shrill. A similar screech told Eragon that the second Ra’zac was behind them.

Roran!

Eragon pivoted just in time to see Roran charge the other Ra’zac, hammer held high. The disoriented monster stumbled backward but was too slow. The hammer fell. “For my father!” shouted Roran. He struck again. “For our home!” The Ra’zac was already dead, but Roran lifted the hammer once more. “For Carvahall!” His final blow shattered the Ra’zac’s carapace like the rind of a dry gourd. In the merciless ruby glare, the spreading pool of blood appeared purple.

Spinning his staff in a circle to knock aside the arrow or sword that he was convinced was driving toward him, Eragon turned to confront the remaining Ra’zac. The tunnel before them was empty. He swore.

Eragon strode over to the twisted figure on the floor. He swung the staff over his head and brought it down across the chest of the dead Ra’zac with a resounding thud.

“I’ve waited a long time to do that,” said Eragon.

“As have I.”

He and Roran looked at each other.

“Ahh!” cried Eragon, and clutched his cheek as the pain intensified. “It’s bubbling!” exclaimed Roran. “Do something!”

The Ra’zac must have coated the arrowhead with Seithr oil, thought Eragon. Remembering his training, he cleansed the wound and surrounding tissue with an incantation and then repaired the damage to his face. He opened and closed his mouth several times to make sure the muscles were working properly. With a grim smile, he said, “Imagine the state we’d be in without magic.”

“Without magic, we wouldn’t have Galbatorix to worry about.”

Talk later, said Saphira. As soon as those fishermen reach Dras-Leona, the king may hear of our doings from one of his pet spellcasters in the city, and we do not want Galbatorix scrying Helgrind while we are still here.

Yes, yes, said Eragon. Extinguishing the omnipresent red glow, he said, “Brisingr raudhr,” and created a red werelight like that from the previous night, except that this one remained anchored six inches from the ceiling instead of accompanying Eragon wherever he went.
