Stutts scraped at the six-inch-wide band with his thumb nail. The color did not scratch off. "It's soft," he said. "Lead, perhaps?"
Sighter and Birdcall examined the mortar, too. Birdcall confirmed with a twitter that the metal was indeed lead.
"Pretty solid," said Wingover, slapping the wall.
"I have an idea," Kitiara announced. The gnomes looked at her as if she'd said she was growing another head. "Well, I do. Here it is: I've seen lots of castle waills fall to besieging armies, and they are often as thick, if not as hard, as these walls. The besiegers brought them down by tunneling under the foundations and undermining the wall."
Consternation spread on the faces in the Breaching Party.
"Why, that's bloody simple," Stutts declared.
"Why didn't we think of that?" asked Flash.
"All we have to do is dig away the sand!" said Wingover.
They fell on their knees and crimson dirt flew. Kitiara, shaking her head, went inside to the ship. Sturm was on his feet, leaning on a crutch that Cutwood had fashioned for him. He was keeping aloof from the preparations, but he asked what the gnomes had decided to do.
"We're digging now," Kitiara remarked. She appropriated a wrecking bar from the store of tools and returned to the frantic diggers. Sturm hobbled after her.
The gnomes carved out a crater deeper than their own height in a very short time. Below grade, the foundation of the obelisk showed no alteration from the structure above — more massive marble blocks joined with lead. Kitiara cleared them out of the hole and swung the iron bar at the stone.
"Wait," said Wingover, "that's solid — "
She drew the bar back in a deep arc and struck the foun dation with all her extra strength. There was a crack, like the breaking of a great tree branch, and a single chip of mar ble flew off. It landed at Sturm's feet, a lost petal from a stone rose. He stooped awkwardly to pick it up.
"Look at the bar!" said Flash.
Kitiara held up the inch-thick rod. The flat prying edge had mushroomed out from the blow, and the whole bar was bent in a graceful curve. Kitiara braced the bar against her knee and tried to straighten it, but only succeeded in bend ing it the opposite way. She tossed it aside in disgust.
"I tried to tell you," Wingover said as Kitiara climbed out of the hole. "The base of the tower rests on the roof of the cavern. It's solid stone."
"There are holes through it," said Sighter. "The Micones' holes. We went through them ourselves, to visit the egg chamber."
"Mining won't work," Stutts said sadly. "We're no more able to bore through the foundation than the upper walls."
Kitiara clambered out of the hole and dusted off her hands and leggings. Her breath showed white in the night air. "It's up to you gnomes now."
The little men faced each other for a few minutes and talked in their lightning patter. Finally, Stutts poked his face out and said, "We'll have to consult with our colleagues."
"Do you have a plan?" asked Sturm.
"The rudiments of one, but we need the wisdom of our fellows inside." The gnomes trooped off.
Sturm pushed the wrecking bar around with his toe.
"That much strength is hard to control, isn't it'!" When Kiti ara didn't answer, he went on. "Are you getting stronger all the time, Kit? Is that why you move as if the world were made of glass?"
She snatched up the iron bar and, holding it in one hand, steadily bent the rod into a right angle — using only her thumb! She dropped the bar and said, "Is that what you wanted to see?"
Cupelix and the humans sat attentively on one side of the obelisk — which is to say, Sturm and Kitiara sat on crates while the dragon sat on his ledge above them. The gnomes sat on a bench facing them. Cutwood had rigged up an easel, which was shrouded with a loose cloth. Stutts stood by the easel, a long, pointed stick in his hand.
"Lady, gentleman, and beast," he began. The dragon's gusty sigh sent Stutts's beard whipping over his shoulder.
"Lady, gentleman, and dragon," Stutts said smoothly, "may
I present the Obelisk Escape Auger, Mark I. He whisked the cloth away, revealing a large sheet of parchment tacked to the easel. A fantastic-looking device was drawn in brown ink. Supported by a massive timber frame was an enormous helical auger, a grossly enlarged version of the tool used by carpenters to bore holes. According to the figures on the parchment, the bit alone was fifteen feet wide, the optimum diameter, Stutts said, to allow Cupelix to pass through.
"Very ingenious," said the dragon, eyeing the peculiar cre ation with evident skepticism. "How is it operated?"
"By this eccentric crank, here." The pointer tapped the drawing. "All eleven of us will man the crank. According to our best estimates, the auger will bore through the wall in sixty-seven hours of work."
"That's almost three days!" Kitiara said.
"On Lunitari, only two days and nights," said Sighter.
"Never mind that," Sturm said. "Where will the steel come from to make the bit? Where will you get the timber to build the frame?"
"Ah," said Cutwood. "Except for the bit blades and a few points of stress, such as the bearings, all parts of the Obelisk
Escape Auger will be made of wood."
"What wood!"
"Why, the hull and frame of the Cloudmaster."
"Ai!" said Kitiara. She let her head fall forward into her hands. Sturm sighed.
"If you dismantle the flying ship, how will we get home?" he said with as much patience as he could muster.
The gnomes looked from one to another, surprised. Very faintly, Fitter said something about putting the ship back together once the dragon was out.
"No!" said Kitiara. "You'll never get the timbers back together as a ship. You fellows must do better!"
"Not to worry!" Stutts rejoined."He whipped the elabo rate drawing of the Obelisk Escape Auger off the easel.
Beneath it was another, equally detailed diagram.'"This, I am proud to say, is the Obelisk Arch Doorway Widener," said Stutts.
"Reasoning that the doorway represents a natural point of entry, we came up with this alternative scheme. These screw jacks — " Again the pointer flew to the diagram. " will be fitted in the doorway. By tightening them with these turnbuckles here, here, and here, the rams will be forced apart, cracking the door wide open."
It took exactly one minute for Sturm and Kitiara to demolish the Arch Doorway Widener, mostly for the same reasons as the Obelisk Escape Auger: lack of quality materi als. There was just no wood or metal to be had, except what the Cloudmaster and its crew had brought with them.
"It seems hopeless," said the dragon with a profound sigh.
"Never!" vowed Wingover. He pushed the bandages up from his face so that everyone could see his eyes. They had turned completely black. Wingover shielded them futilely with his hands.
"You see what has happened to me," he said, "I no longer can shut out anything. I have to sleep face down to the ground, where I count strata all the way down to the moon's core." He pointed with a thumb at Cutwood, next to him.
"My good colleague hears every grain of sand rubbing against another. Roperig's hands are almost sealed together, aren't they, Roperig? Rainspot's clothes are beginning to rot from the constant damp. All the rest of us have problems, too, but we won't leave until we solve this problem."
Sturm heard these words carefully. He said, "As long as we are discussing our gifts, let me show you this." He tore the cloth bandage from his leg. Where two nights and a day before there had been an ugly, gaping wound, there was now only smooth, unscarred skin.
"The same magic that makes trees walk and fight has healed my wound. I did not ask for it to be done, but it has convinced me of one thing. This is no place for mortals. I'll lend my aid, dragon, for that reason alone. The longer we remain on Lunitari, the more the magic will affect us. Since my companions have resolved to help you, my resistance only impedes their progress."
