The bends and turns gnawed through the earth by the Urkhan worms thus appeared to Tarn's eyes as though lit by bright moonlight. His companions were outlined in warm red, especially wherever their flesh was exposed to the open air. They wore iron-shod boots to hide their footprints from other creatures of the deep earth, who could track the residual heat left in stone by a person's tread. The Klar also painted their faces and caked their beards with white clay before battle, because white was the color of hiding among those with darkvision. To Tarn, their faces were blank masks in the dark, visible only by the heat of their open eyes; to their enemies, such faceless visages were terrifying.
Tarn guessed that they were nearing the city of Qualinost. He urged his guards to greater speed. They began to splash through muddy puddles where before there had been dry stone or moist earth.
"Are we near the tunnel entrance?" Tarn huffed as they jogged along.
"Not yet," Captain Mog answered from the front of the party. "This tunnel will slope down to join the main passage before entering the city. But we're close."
Tarn grunted in acknowledgment, hiding his anxiety under his customary gruff exterior of command. He feared the worst. The evacuation of the elves had been going as planned, with the last refugees escaping into the tunnels before Beryl's expected daylight attack. He and King Gilthas had been rounding up stragglers when a great blast of chill, wet air roared up behind them, from the direction of the city. The young elf king had wanted to return, but Tarn had urged him to lead the refugees to safety while he took his personal guard and investigated. Gilthas had reluctantly assented, marching off with his elves while Tarn turned back, the damp wind in his face speaking volumes that only a dwarf could read.
He dared not speculate as to the cause of the wind or the tunnel collapse that had dumped them into the Urkhan pen, but as he had said, he could feel the tension of the earth through his feet as he ran. The ground almost seemed to vibrate with the strain, the floor to hum like a harp string pulled to the breaking point.
They stopped at another partial collapse of the tunnel. Fallen beams crisscrossed the passage like the web of a spider, and sections of the roof had fallen, blocking the way. Captain Mog led the digging, clearing a path through the rubble for their king to follow. Tarn impatiently slapped the pommel of his sword while he watched them excavate. The Klar were not careful miners, but they were quick, strong-backed, and stubborn. They heaved beams aside or hacked through those too tightly wedged against the tunnel walls to budge. They clove through mounds of rubble with their hands, pushing, clawing, snarling, and cursing at the work. Earth, dust, and small pebbles sifted down from the unstable roof, threatening to bury them all, yet they pushed onward, needing little encouragement.
Soon, they cleared a path, but as they crawled through the last few feet of rubble, the beams around them groaned and cracked, pouring black soil, leaves, and twigs onto their heads. At the same time, something large and heavy struck the wall a tremendous blow. They clambered to their feet to find another section of tunnel collapsed not thirty feet ahead. Half-buried by tons of stone, an Urkhan worm was thrashing in pain and torment, its huge head hammering the walls, floor, and groaning roof. The monster was enormous, the largest and oldest in their stables. They had used it to burrow out the main passageways. Its tubular body was as thick as three dwarves standing on each other's shoulders. Its three jaws were large and powerful enough to shear through granite boulders. Two horns, each thicker than Tarn's wrist, sprouted from the creature's enormous head. With each blow, dirt and pebbles poured through ever-widening cracks in the ceiling.
"Kill that thing before it brings down the whole tunnel!" Tarn shouted.
Four of his Klar bodyguard rushed the monster, but their axes seemed to bounce off its rubbery reddish-brown skin. One dwarf dived beneath the creature's upraised body and stabbed with his dagger into the joint between two of its body sections. He disappeared with a sickening crunch beneath the monster as it flailed him to a pulp. Another dwarf managed to hack off one of the worm's horns, to which was still attached a length of broken harness rein. Writhing in agony, the huge worm spat a glob of clear viscous fluid. The glob splashed over the dwarfs upraised shield, coating his face and left hip. Immediately, his flesh began to hiss and smoke. Screaming in agony, he dropped shield and axe to claw at his dissolving face. Tarn jumped toward him and jerked him out of the way just as the worm's enormous head swept down, flattening his shield like the blow of an enormous hammer.
