hollowed out by a hole through the center.
'What is that?' asked Perry, puzzled.
'A climbing harness,' replied Bonn.
'And what are those things fastened to it?' Perry pointed to the metal objects.
'Rock-nails. Rings. Jams,' answered Bonn, unfastening one each of the three types of devices and handing them to the Warrow, who held them in the lantern light to examine them closely. Bonn spoke on: 'Heed: with the nail, you drive the spike into a thin crevice in the stone, then snap a ring through the eyelet; one of several leather straps is then clipped between the climbing harness and the ring. You haul yourself up and along as you go, suspended by strap on a trail of driven rock-nails and attached rings. When you come to a place where the crevices are wider, you wedge a proper-sized jam in place, slipping a snap-ring through the hole, using it instead of a nail.'
Borin turned to Lord Kian. 'I will make the climb, and once across I will let myself down; and then we will fix a rope over the Great Deop for the rest to use; or we will haul the bridge back up, and all can stride above the dark depths on its broad span.'
Perry examined the devices while Borin prepared himself for the climb, putting on the. tackle, buckling the cross straps of the harness and cinching tight the wide belt burdened with the rings, nails, and jams. The Dwarf also attached hanks of rope to the belt; and he tied a small hammer by a thong to his wrist.
'Here,' rasped Anval, fastening a thick leather pad to the hammer face, 'it will deaden the sound of each strike.' Borin nodded but said nought, for his gaze was sweeping up and across the roof.
'It is a long reach,' growled Borin to his brother as they
surveyed the intended route. 'Should I need more climbware, I will drop a line to you.' Anval merely grunted in reply.
The Ironfists selected a place to start, and Perry gave Bonn back the nail, jam, and ring. The Dwarf reached up high on die wall beside the stairs and with muffled blows drove the rock-nail into a thin crack; then began the perilous climb.
Quickly, Borin drove nail after nail into the stone, clipping and adjusting an appropriate harness anchor strap to each new nail as he went, unclipping the hindmost strap and retrieving the free snap-ring as he left each embedded nail behind; and up like a fly he clambered. At times there were handholds, and he did not use the rock-nails as he ascended. At other times, however, long still study was needed before he drove a nail or wedged a jam and moved onward. At last he topped the wall and started across the ceiling, the Dwarf now totally dependent upon the leather belting, rings, nails, jams, and harness. Perry was glad that it was not he who had to climb so high and dangle like a Yule decoration, and he was amazed by Borin's ability. 'How surely he goes,' breathed the Warrow, looking up, knowing that were their places exchanged he would be frozen with fear.
'Aye,' answered Delk. 'Borin is accounted a master stone climber-even among the CMkka.'
'You speak as if all Dwarves climb like that,' said Perry.
'Aye,' responded Delk, 'for the inside of a Mountain needs climbing more than its outside ever does. And the Chilkka have been climbing Mountains since we and they were created-yet we more often climb within the living stone than without. Even so, mayhap Borin is the best of us all.'
Once again Perry turned his sight toward the Dwarf above. Yet Borin's progress had slowed markedly, for he was now on the most difficult, the most hazardous reach.
Bit by bit, the Dwarf inched across the ceiling as precious time eked beyond recall into the past. And Perry fretted that the climb had already taken too long, and that more time would be spent ere the task came to an end; for the buccan knew that at any moment a Rucken band could swarm into the War Hall. These thoughts were on Lord Kian's mind too, for the young Man said to Shannon, 'It is now that Borin is most vulnerable to Yrm arrow; if Spaunen come, we must slay any archers first.' Perry's heart sank at these dismaying words, and his eyes once again turned to the exposed climber. And up above, the Dwarf crept onward as the sands of time ran swiftly down.
Hours later, it seemed, Borin, now well out over the chasm, called down to the companions below, pitching his voice so that it would not carry into the caverns to be heard by hostile ears: 'Ziggurt!'
'What did he say?' asked Perry.
'Ziggurt,' replied Delk. 'It is one of the many ChSk words describing the condition of rock. Borin says the roof stone where he is, is ziggurt. That means it is not completely sound; perhaps when the Great Deop first split upward, reaching into the Mountain from below, the stone was stressed so.';
'Does that mean it's going to fall?' asked the Warrow, yielding back.
'Nay,' Delk assured him. 'Ziggurt is not rotten stone, yet it may give way, but only if stressed more. Ziggurt means that the rock is crazed, that it has many small cracks and large, and fissures running widely through it. The rock is untrustworthy for bearing weight: small chunks may fall if pulled upon; large slabs can shatter down if stressed just so. No, ziggurt does not mean weak stone; it can be very strong and stand forever. But long careful study is necessary beforehand when working the stone, to prevent mishap. Yet ziggurt is more than I have just told you. Pah! The Common Tongue is not suited to any better description than that; it is not capable of shading the meanings of stone as is the Chak Speech.'
'Time, Delk?' asked Kian. 'There is the rub: you have said that time is needed to work ziggurt rock to prevent mishap; yet I deem that our time is nigh gone. Other Yrm patrols will come, and we must be away ere then with no trace of our passage remaining. If Gnar suspects that his enemies are within these caverns, he will turn out all of his forces to search for us. And we do not want a Spaunen Swarm hunting through the halls, seeking our party. No, our only hope to help Durek is to win through without alerting the entire Yrm army.' In a muted voice, Kian called up to Borin, 'Can you go on?'
'It is ziggurt for as far as the eye can see,' Borin called back down, waving a hand across the gulf and toward the Mustering Chamber. 'But I must try, though it will be a gamble, for the way is obscured by soot from the time the ancient bridge burned, and long study is needed, yet we have not the lime. I must chance a hasty crossing.'
'Wait!' softly called Shannon, cupping his hands about his mouth so that his voice would reach the Dwarf above. 'There is this: if you can lower a rope to me, I can swing across-if the stone and iron rock-nails will bear my weight.' The Elf looked at Lord Kian. 'Except for Perry, I am the least heavy, and you cannot risk him on this scheme.' Lord Kian nodded his assent.
Borin hammered in another rock-nail, and then like a swaying spider strand a thin, strong line came snaking and swinging down out of the overhead gloom. Borin had tied his hammer to the end to give the rope a pendulum weight, and he swung it as he payed it out. Shannon nimbly caught the line on one of the long arcs, and as soon as Borin called down that all was ready, the Elf gave the company a rakish grin and sprang off the edge of the Deep.
Shannon's first long swing was not far enough, and he rose to the end of his arc, seemed to pause, and then hurtled back across the yawning gulf. On the second swing he pumped hard over the bottomless pit and carried farther still, though it was not yet enough. On the third pass he almost gained the far lip of the chasm, but not quite.
Only Borin, clenched against the ceiling by the short anchor straps, did not see the Elf come closer and closer with each plunge; instead, the Dwarf kept his eye riveted to the rock-nail. The swings were placing heavy stress on the eyeletted spike, and Borin intensely watched the crevice the nail blade was driven into. On the third arc, a stone chip flaked from the crack: the nail was coming loose! Quickly, Borin jammed his right forearm up into a large ziggurt cleft and made a fist, wedging his clenched hand tightly in the rift; he wrapped the loose end of the pendulum rope around his left arm and forcefully gripped it. No sooner had the Dwarf caught hold than the nail tore loose, and the weight of the plummeting Elf jolted through Bonn's arms and shoulders.
Silverleaf was swinging back from the far lip when he felt the rope give then catch again, and the jar nearly shook his grip loose, the line slipping in his grasp ere he caught tight. His grip firm again, he continued his arc and pumped hard on the next plunge across.
Borin strained desperately to hold on, gritting his teeth and closing his eyes with the effort, his great arm and shoulder muscles cracking with the stress, for he was the anchoring link between the stone overhead and the taut rope to the Elf hurtling the abyss below. The greatest strain came when Shannon hurtled through the bottom of the arc, and Borin strove to hold on: his right fist, jammed in the crack, felt as if the bones in his hand were breaking, and the rope wrapped around his left arm seemed as if it were cutting through the elbow, and his
