"Come," said Ebbitt, seeing the question on his face. "The answer lies in the throne."

  CHAPTER EIGHTEEN

  The lonely structure in the center of the Audience Chamber was the Imperial Throne of the Chosen. Carved from a single rainbow crystal, it was an ornate and enormous chair wide enough to seat three people. The back of it rose ten stretches from the seat, and was finger-thin. Light shone through it as if it were a thick pane of beautiful, multicolored glass.

  A ring of Sunstones was set in the floor around the throne--large, violet Sunstones soldered in place with gold.

  "So what is the answer?" asked Tal as they all stood looking at the throne. He also cast a suspicious eye at the ring of Sunstones. They were too big and too purposefully placed to be decorative. They had some function, probably defensive. ,

  They might project heat or flame, or something equally dangerous.

  "The way to the Violet Tower," said Ebbitt, "lies on the throne. Though only the bearer of the Violet Keystone may use it."

  Tal looked at Milla. He felt ashamed--Milla would never have lost her half of the Keystone to Sushin, and she probably despised him for letting their enemy get such a vital thing.

  Milla met his gaze. Then she twisted the Sunstone ring off her finger and threw it to him.

  He caught it reflexively, more surprised than he ever had been in his life.

  "Milla!" exclaimed Malen. "What are you doing?"

  "Returning the Emperor of the Chosen's Keystone," said Milla calmly. "Though I would like your other Sunstone in return, Tal."

  Wordlessly, Tal threw her the Sunstone he had taken from Fashnek. Then he slipped on the half Keystone. It pulsed with sudden Violet, a light that was answered by the ring of stones in the floor.

  "Take it back," said Malen, her voice cool. Her eyes were cloudy, Tal saw. She was communing with the other Crones. "The stone is the Icecarls' now. Take it back, War-Chief."

  Jarek grunted and started toward Tal, but stopped as Milla raised her hand.

  "I do not know how to use it to its fullest strength," she said, speaking not to the Crone in front of her, but all the other Crones beyond. "Tal has the power, and the right. What is more important? Squabbles between Icecarls and Chosen, or saving the Veil?"

  Malen was silent. Tal could not know what was happening, but Milla did. The Crones were arguing among themselves and needed to vote.

  "How exactly does the throne tie in with the way to the Seventh Tower?" whispered Tal to Ebbitt as the silence dragged on.

  Ebbitt shrugged. Tal noticed the old man was keeping a wary eye on Jarek.

  "Sit on it and we'll both find out," whispered Ebbitt.

  Malen coughed. Everybody stood absolutely still. Jarek's chain slowly unfolded from his hand, link by clanking link.

  "Very well, War-Chief," Malen said in the strange combination voice of the massed Crones, her words echoing through the chamber. "Once more we follow your lead. We have chosen well."

  Trust the Crones to congratulate themselves for giving in, thought Milla.

  "Thank you," Tal said to Milla. "Ebbitt thinks I should sit on the throne."

  "We should all sit on it," said Ebbitt, who was peering down at the Sunstones in the floor, then back up at the dome high above them. "Tal, you go first."

  Tal looked at the Sunstones in the floor, too, and remembered his earlier thoughts. To be on the safe side, he summoned Violet from the Keystone once more, letting it wash all over him. Then he stepped across the ring.

  The stones in the floor glowed, but did nothing else, not even when Ebbitt and the others followed Tal.

  The throne was cold and hard. There was a dusty cushion on the seat, but it had long lost any comfort it once offered and was so dusty that Tal sneezed every time he moved even slightly.

  Ebbitt came and sat on his left, and Milla on his right. Crow crouched next to Ebbitt, and Malen squeezed in beside Milla. Jarek knelt down in front of Milla and Malen, watching Tal balefully. Ebbitt's maned cat flung itself down in front of the throne, under all their feet. Adras and Odris drifted up to hang on either side of the throne's back, like strange heraldic retainers.

  "Bit crowded," remarked Tal. "What do I do now?"

  No one answered.

  "Great-uncle Ebbitt? What do I do now?"

  "You're the Emperor," snapped Ebbitt. "How would I know? Do something imperial, you idiot."

  Tal bit back a hasty reply. If he was the Emperor, surely he deserved to be addressed as something more respectful than "you idiot." Not that there was much hope of that from Ebbitt.

  Still, perhaps the advice was good, however it was offered. Tal raised his hand and summoned forth more Violet, sending a beam of it straight at the circle of Sunstones on the floor.

  The stones answered immediately, flaring so brightly that everyone had to shield their eyes. At the same time, the Sunstones in the rim of the dome shone brighter, and rays of Violet struck down. Hundreds of distinct rays, from every part of the rim, connected with the circle around the throne.

  "Well done," said Ebbitt.

  "It looks pretty," said Tal dubiously, watching the dust rise through the Violet streams. "But it doesn't seem to be doing anything."

  "Apart from lifting us up, you mean?" asked Milla.

  Tal looked at her, then back down at the floor. As usual, she was right. The throne and the circle of floor around it were slowly rising toward the dome, suspended on the hundreds of beams of Violet from the rim. They were already a good twenty stretches up.

  "Yes," he said weakly. "Apart from that."

  "Well, the dome is opening at the top," added Crow. "I suppose that could be counted as something else. I guess that's how we get to the bottom of the Violet Tower."

  "Sure to be," said Tal, trying to sound confident. "But Sushin may have set some sort of trap there, or he might be there himself still. We'll have to be careful."

  Silently and steadily, the throne continued to rise. Tal tried not to think of what might happen if the magic failed part of the way up. Odris and Adras might be fast enough to save him and Milla, but the others would fall to their deaths. They were already a hundred… no, a hundred and fifty stretches up… with a hundred to go, and a very hard floor below.

  The magic did not fail. The throne passed through the circular gap in the dome and came to rest in another, much smaller room. It was also completely bare, and there were far fewer Sunstones set in the ceiling. A broad staircase made from a pale green, highly polished stone wound up in one corner.

  "Welcome to the Seventh Tower," said Tal as they stepped off the throne and walked toward the stairs.

  His voice sounded strange and doom-laden, even to him, and he wished he hadn't spoken.

  CHAPTER NINETEEN

  As soon as Tal left the circle of Sunstones, the throne began to sink again, back down to the Audience Chamber. Ebbitt, who had been lingering, had to jump out, assisted by his Spiritshadow, who lifted him by his collar much as it would carry a kitten.

  There was no sign of Sushin, or any visible trap. Even so, Milla gestured to Jarek to go ahead of them, up the green stone stairs. He was not only tough enough to withstand a light trap, but was also a very experienced hunter, likely to detect any ambush.

  The stair led up to another level, and another chamber that was empty and bare. But the stair did not continue farther, and there were four large doors to choose for further exploration. All the doors were made of the golden metal, Tal noticed, and the walls were also lined with a close mesh of golden metal against the stone. No Spiritshadows could pass through doors or walls here.

  "Dark take it!" swore Tal. They couldn't afford any delay by going the wrong way. "That's all we need. Which one do we take?"

  "Just follow Sushin," said Ebbitt. "Elementary tracking, my boy."

  Tal looked at the stone beneath his feet and stamped in exasperation. As he'd expected, even stamping left no mark on this floor. There wouldn't be any tracks to follow.

  Or so he t
hought, until he saw Jarek at one of the doors. The Wilder licked his finger and ran it along the joint between door and wall, before examining the result. Then he sniffed around the door handle, which was made of Violet crystal and golden metal. He did this at all four doors, running between them, before pointing at the door on the eastern side.

  "What?" asked Tal. "How can he tell?"

  "Dust," replied Milla. "Or the lack of it. And a hand leaves oil or sweat on metal. Come on!"

  "But he couldn't smell that," said Tal. "Could he?" Milla didn't answer. She ran toward the door and stood off to one side, the Talon ready. Odris glided over to the other side, Adras next to her.

  Jarek tried the door handle. It didn't turn, even when the huge Icecarl began to exert his full strength.

  "The Keystone!" snapped Ebbitt. "Use your head, Tal. We can't wait around for you to get on with it!"

  Tal flushed and raised the Keystone, directing a beam of Violet at the door handle. It was reflected back, and suddenly the handle turned under Jarek's hand, and he thrust it open.

  The Wilder sprang through, drawing his chain as he ran. Milla followed him, the Talon extending, followed by the Spiritshadows and Tal and Crow, with Ebbitt and Malen behind.

  All of them expected some sort of trap, or enemy left behind by Sushin. But they didn't expect to see a gigantic insect, an awful thin-bodied creature at least fifty stretches long, with hundreds of segmented legs, serrated mandibles longer than Jarek, and two huge multifaceted eyes.

  Light flared in Sunstones, the Talon extended into a whip of light, and Jarek whirled his chain above his head.

  Then everyone stopped. The light faded. Milla let her hand drop to her side and Jarek's chain slowed its terrifying whirl and came to what would be a bruising stop on anyone's side but his own.

  The giant insect was dead. Or had never been alive. As they moved forward, Tal saw that it was actually a machine of some kind. It was made of something like the golden metal, though this material had a greenish sheen on the gold. And the great multifaceted eyes were actually made up of hundreds of Sunstones. Dead Sunstones.

  It had a sort of saddle high on its back, behind the head with its terrifying mandibles, and the two closest legs had blunt bristles that could be used like rungs on a ladder, where all the other legs had razorlike protrusions.

  "A war beast," said Milla in awe. This would be a terrible foe. It was thin enough to slip through anywhere a human could stand upright, but those mandibles could cut a warrior in two, and the legs slice a hundred foes into pieces.

  "A Wormwalker," said Ebbitt. "Fascinating. I always thought they were made up."

  "They?" asked Crow. "There are more of them?" "According to the stories, at least a score," said

  Ebbitt happily. He produced a measuring tape from one of his ample pockets and stretched it between the Wormwalker's mandibles.

  "Not now, Great-uncle," said Tal firmly, taking the old man by the elbow. "We're in a hurry, remember?"

  They walked quickly past the Wormwalker, careful to keep away from its sharp legs. The insect machine was actually positioned along a curving corridor, and as they rounded the bend, they saw another war machine. Only this Wormwalker was posed differently, its head and part of the body behind reared up, as if it were about to strike down an enemy.

  It appeared as dead and frozen as the first one, but everyone slowed down again except Jarek, and even he circled the head warily and kept his chain at the ready.

  "I wonder how many Sunstones you'd need for each one of these," Tal wondered as they passed. There was a third Wormwalker ahead, like the last reared up in an aggressive attitude.

  Ebbitt looked at something under his breastplate and answered absently.

  "Seven hundred of at least strength-eighty stones in each eye for full operation. They have not been used since the time of Ramellan and the Shadow Wars."

  His Spiritshadow had to nudge him aside from the Wormwalker's legs as he spoke. It was finally clear that he was reading something, something he had stuffed down the front of his robe, against his chest. It wasn't just a weird new habit he'd chosen to annoy Tal.

  Tal had a good idea what Ebbitt had concealed there, though he couldn't work out how the old man was carrying it, when it weighed as much as he did.

  Ebbitt caught Tal's frown, looked down inside his robe again, and coughed.

  "I was going to tell you," he said. "But it slipped my mind."

  "I thought it couldn't change its weight," complained Tal. "It nearly dislocated my arm before!"

  "It can't do some alterations itself; you have to ask it the right way," said Ebbitt. "Fortunately I have researched some of the phrases for commanding its obedience. Though not all, by any means, and it is a tricky bit of… of whatever it is…"

  Tal called out, for he and Ebbitt had slipped a little way behind. "Ebbitt has the Codex!"

  Milla turned back to look but Jarek continued on past her. As the Wilder walked on toward the third Wormwalker, Tal saw a sudden glint appear in its eye--and multiply like fire across a pool of oil.

  CHAPTER TWENTY

  "Look out!" screamed Tal, but even as the words left his mouth the Wormwalker struck. Its mandibles snapped down at Jarek, gripping the Wilder around the waist. He dropped his chain, and his mighty arms pushed against the creature's jaws, trying to keep them apart. Anyone else's hands would have been sliced through, but Jarek's strange skin resisted the mechanical insect's serrated mandibles. Even so, strong as he was, it was clear the Icecarl would soon be crushed.

  Tal immediately raised his Sunstone and fired off a Red Ray of Destruction, only to see it absorbed by the Sunstones in the Wormwalker's eye. Adras and Odris flew forward, but as they tried to grip the creature's mandibles to help Jarek, they found themselves repelled by the green sheen on its surface, which was now sparking--another Sunstone-powered effect.

  Milla attacked, too, whipping a light rope around the Wormwalker's head. But just as the Spiritshadows could not touch the metal, the rope of light was repelled.

  Crow threw a knife at one eye, and was gratified and surprised to see a few Sunstones fall out, but not enough to make a difference.

  Jarek roared, the Spiritshadows boomed and shouted, Milla cried a war cry, and Ebbitt said something to Tal as he fired another Red Ray, this time aiming at the thing's front set of legs.

  "What?" shouted Tal. Ebbitt was bobbing around at his side and muttering while trying to read something from the Codex he had under his breastplate.

  "The top of its head!" shouted Ebbitt. "In front of… in front of the saddle. You have to pull its… er… brain out."

  Tal looked at the Wormwalker, which was shaking Jarek back and forth, its long body undulating wildly behind it all along the corridor. Milla was dancing about in front of it, whipping the light rope from her Talon across its eyes. With every third or fourth stroke, a Sunstone would fail to resist and explode, but there were too many for that tactic to work.

  "In front of the saddle?" asked Tal quickly. "Yes!"

  Tal sized up the Wormwalker's motion and started to run. As he ran, he shouted to Adras. "Adras! Adras! Throw me onto the thing's head!"

  Adras turned at his voice, but didn't seem to understand. Tal had a momentary vision of the Spiritshadow simply stepping aside to let him slide under the Wormwalker and into the forest of its razor-sharp legs.

  "Throw me!" he screamed. "Onto its head!"

  The Spiritshadow finally got it. He cupped his hands a second before Tal reached him. The Chosen boy leaped, had his feet caught for an instant, and was thrown through the air, over the mandibles and the still-struggling Jarek.

  He came down hard on the Wormwalker's head and started to slide off, the wrong side, down to the sharp legs. But the saddle was only a handsbreadth away, and he managed to stretch himself to what he was sure was much more than his usual height and grip on to it.

  A moment later he had spun around and was in the saddle, holding on desperately as the Wormwalker arc
hed, undulated, and shook in an effort to dislodge him.

  Tal held on to a ring just in front of the saddle with one hand and clawed at a round panel set in the thing's head, which was the only possible clue to where its brain might be. All his nails broke, but he managed to flip it open. Underneath there was a single Sunstone set in the top of what looked like a crystal cylinder or tube full of a pulsing green fluid.

  Tal forced his fingers into the receptacle and tried to pull the cylinder out. But he couldn't get a grip, and he was nearly thrown out of the saddle as the Wormwalker redoubled its efforts to shake him off. It was gyrating up and down from the floor and smacking itself against the ceiling, so that Tal had to fling himself right down on the saddle to avoid being crushed.

  "Do… thing imp…!" shouted Ebbitt, his voice only just audible above the din. Tal took a second to translate this in his head as "Do something imperial!"

  Tal grimaced, concentrated, and fired a pulse of pure Violet at the Sunstone atop the cylinder. It answered with a flash, and the cylinder popped half out of the receptacle. Tal grabbed it, pulled it the rest of the way out, and flung it over the side.

  He almost went over himself, as the Wormwalker froze in midundulation. His hand, already sore from the climb up the slopdown, was burning and bleeding again and he had the familiar feeling of a nearly dislocated shoulder.

  Climbing down, he found Ebbitt examining the long crystal tube. It was full of green lumps of something disgusting-looking, floating in what could be cooking oil but almost certainly wasn't.

  "Well done," said Ebbitt, sliding the tube through his belt. "Very considerate of you to get one of these for me."

  Tal shook his head. "I hope there aren't any more Wormwalkers ahead of us," he said. "Ebbitt, can you ask the Codex where Sushin is? It must have taken him quite a while to get this thing going again, so maybe he isn't too far ahead."

  Ebbitt nodded, which to Tal meant yes, as he ducked under the Wormwalker's head to where Milla, Crow, and Malen were standing solemnly looking up at the body of Jarek.

  One look told Tal that somewhere in those last few seconds of struggle, Jarek's strength had failed him, and the mandibles had closed.
