What interested him most, however, was not the wall or the buildings, but the fact that much of the city lay shadowed underneath a huge stone shelf, which must have been over half a mile wide and five hundred feet thick at its narrowest. The overhang formed one end of a massive, sloping hill that stretched off to the northeast for several miles. Atop the craggy lip of the shelf stood another wall, like that which surrounded the city, and several thick watchtowers.

At the back of the cavelike recess underneath the shelf was an enormous citadel adorned with a profusion of towers and parapets. The citadel rose high above the rest of the city, high enough that it almost scraped the underside of the shelf. Most intimidating of all was the gate set within the front of the fortress: a great, gaping cavern that looked large enough for Saphira and Thorn to walk through side by side.

Roran’s gut tightened. If the gate was any indication, Shruikan was big enough to wipe out their whole army by himself. Eragon and Saphira had better hurry up, he thought. And the elves too. From what he had seen, the elves might be able to hold their own against the king’s black dragon, but even they would be hard-pressed to kill him.

All that and more Roran took in as he paused on the ridge. Then he tugged on Snowfire’s reins. Behind him, the white stallion snorted and followed as Roran resumed his weary march, following the winding road as it descended to the lowlands.

He could have ridden—was supposed to ride, actually, as captain of his battalion—but after his trip to Aroughs and back, he had come to loathe sitting in a saddle.

As he walked, he tried to figure out how best to attack the city. The pocket of stone Urû’baen sat nestled within would prevent assaults from the sides and the rear and would interfere with attacks from above, which was surely why the elves had chosen to settle in that location to begin with.

If we could somehow break off the overhang, we could crush the citadel and most of the city, he thought, but he deemed that unlikely, as the stone was too thick. Still, we might be able to take the wall at the top of the hill. Then we could drop stones and pour boiling oil onto those below. It wouldn’t be easy, though. Uphill fighting, and those walls … Maybe the elves could manage it. Or the Kull. They might enjoy it.

The Ramr River was several miles north of Urû’baen, too far to be of any help. Saphira could dig a ditch large enough to divert it, but even she would need weeks to complete such a project, and the Varden did not have weeks’ worth of food. They had only a few days left. After that, they would have to starve or disband.

Their only option was to attack before the Empire did. Not that Roran believed Galbatorix would attack. So far the king had seemed content to allow the Varden to come to him. Why should he risk his neck? The longer he waits, the weaker we grow.

Which meant a frontal assault—a brazen fool’s charge over open ground toward walls too thick to breach and too tall to climb while archers and war machines shot at them the whole time. Just imagining it made a sweat break out on his brow. They would die in droves. He cursed. We’ll dash ourselves to pieces, and all the while Galbatorix will sit laughing in his throne room.… If we can get close to the walls, the soldiers won’t be able to hit us with their foul contraptions, but then we’ll be vulnerable to pitch and oil and rocks being dropped on our heads.

Even if they managed to breach the walls, they would still have the whole of Galbatorix’s army to overcome. More important than the defenses of the city, then, would be the character and quality of the men the Varden would face. Would they fight to their last breath? Could they be frightened? Would they break and flee if pushed hard enough? What manner of oaths and spells bound them?

The Varden’s spies had reported that Galbatorix had placed an earl by the name of Lord Barst in command of the troops within Urû’baen. Roran had never heard of Barst before, but the information seemed to dismay Jörmundur, and the men in Roran’s battalion had shared enough stories to persuade him of Barst’s villainy. Supposedly, Barst had been lord of a rather large estate near Gil’ead, which the invasion of the elves had forced him to abandon. His vassals had lived in mortal fear of him, for Barst had a tendency to resolve disputes and punish criminals in the harshest manner possible, often choosing to simply execute those he believed were in the wrong. Of itself, that was hardly notable; many a lord throughout the Empire had a reputation for brutality. Barst, however, was not only ruthless but strong—impressively strong—and cunning to boot. In everything Roran had heard about Barst, the man’s intelligence had been clear. Barst might be a bastard, but he was a smart bastard, and Roran knew it would be a mistake to underestimate him. Galbatorix would not have chosen a weakling or a dullard to command his men.

And then there were Thorn and Murtagh. Galbatorix might not stir from his stronghold, but the red dragon and his Rider were sure to defend the city. Eragon and Saphira will have to lure them away. Otherwise, we’ll never make it over the walls. Roran frowned. That would be a problem. Murtagh was stronger than Eragon now. Eragon would need the help of the elves to kill him.

Once again, Roran felt bitter anger and resentment welling up inside him. He hated that he was at the mercy of those who could use magic. At least when it came to strength and cunning, a man might make up for a lack of one with a surfeit of the other. But there was no making up for the absence of magic.

Frustrated, he scooped up a pebble from the ground and, as Eragon had taught him, said, “Stenr rïsa.” The pebble remained motionless.
