The forest was almost a black outline against the morning sun, and Nylan's eyes rose to Freyja, glittering mercilessly in the cool and the clear morning light.

After a moment, he urged the mare up the hill. Rather than dismount and risk revealing too much, just in case the Lornians' wizard could see what he did, he rode past each post of the lower line slowly, letting his senses range over what he had constructed. The weights and links seemed sound, and all the cords were in place. Then he repeated the effort with the upper line before easing the mare up to the crest of the ridge.

All he saw on the northeastern side was what he always saw. There were no massed bodies, no horse soldiers, just grasses and road and trees.

He squinted and studied the area to the west. Perhaps there was a low cloud of dust rising above the trees that bordered the wide meadows leading toward Westwind, but the trees shielded his vision.

After a time, he turned the mare and rode back down the road and across the meadow to the laser.

"See anything, ser?" asked Huldran as he rode past the front of the quickly bricked emplacement. "Some dust, I think, but it wasn't moving that fast."

"It never is," said Relyn, "unless it's on the field and moving right toward you.

Then the horses and dust rush at you. At the same time, you feel like they move so slowly."

Nylan reined up and tied the mare in back, beside Huldran's mount where she would be largely sheltered from stray arrows or crossbow bolts or whatever missiles the Lornians might employ. Then he checked the laser again.

For a while, as the sun climbed, and he began to sweat under the leathers, he walked back and forth. Then he wandered out into the grass. Except for the six of them, the entire Roof of the World appeared empty. The tower was barred and silent, and even the insects seemed quieter than normal. Or was that his imagination?

"Why are battles always fought on clear days?" asked Nylan to no one in particular as he sat down in the narrow slit entry, his boots resting on packed clay that had once been grass.

"They are not," answered Relyn from the left side of the emplacement. "I have fought in rain and mud. Not snow."

The smith-engineer nodded. Then he looked at the man in black. After a time, he got up and walked back and forth behind the silent and still unpowered laser.

He looked at Relyn a moment, then beckoned, and walked away from the emplacement, letting the one-armed man follow. He stopped a hundred cubits out into the meadow and turned.

Relyn frowned. "What is it?"

"After this is over, it's time for you to leave-as soon as you can." Nylan glanced uphill, but nothing had changed.

"The Angel?"

Nylan nodded. "One way or another, I won't be in very good shape after this.

Too much killing is hard on me." He met Relyn's eyes. "I promised. But don't lay a hand on anyone, or I'll chase you to the demon's depths."

Relyn shivered. "I would not, not after all this. Not after what I owe you." He shrugged, then smiled bitterly. "First, we must triumph."

"Don't prophets always win?" Nylan gave a wry grin and walked back toward the laser emplacement.

Relyn followed more slowly, fingering his chin with his left hand.

Huldran glanced from Nylan to Relyn, then just shook her head.

Shortly, a small group of riders appeared just over the crest of the hill, but turned their mounts to face the other way, presumably down on the advancing Lornians. Nylan thought he saw Ryba's latest roan, but he couldn't be quite sure.

Nylan was blotting his forehead, and even Relyn had opened his jacket by the time a single rider cantered down the road from the ridge. Nylan didn't know her name, though he had seen her in training, and she rode well.

"Ser! The enemy is about a third of the way up the ridge. The marshal said that she won't be able to send any more reports."

"Fine. Tell her to make sure the field is clear when the enemy comes down. Do you understand that?"

The guard's face crinkled. "The field must be clear when the enemy comes down?"

"The field must be clear of guards when the enemy comes down." Nylan corrected himself. "Do you have it?"

She repeated the words, and Nylan nodded. Then she turned her mount and started back up toward the ridge.

Relyn looked at Nylan's face. "You plan some terrible magic."

"It's not magic. Not mostly," Nylan added as his head throbbed as if to remind him not to lie, "but, if it works, it will be terrible." He muttered under his breath afterward, "And if it doesn't work, it's going to be terrible in a different way."

"What do you want us to do?" asked one of the new guards.

"When the engineer works his magic," answered Huldran, "his body will be here, but his thoughts will not. Our job is to protect him from anyone who would attack."

Nylan hoped no one got that near, but somehow nothing worked quite the way it was planned in any battle. Or in anything, he added mentally.

As the faint and distant sounds of the tumult mounted and purple-clad riders finally crested the ridge, Nylan powered up the firm cell assembly-seventy-seven point five percent. Could he smooth the flows for the fiery weapons head, the way he had for the industrial laser heads?

Another wave of purple riders reached the ridge top, and the Westwind guards began falling back, drawing back across the ridge top, sliding westward toward the road to the tower.

The Lornian forces slowed where the pikes should have triggered, but Nylan could not see what exactly had occurred, except for the unseen whiteness that signified death and more death.

Nylan sent out his perceptions, his eyes still on the hillside above. He could almost sense the Lornian commander, the arrows falling around him as the man gestured with the big blade. Idly, Nylan thought that he could have shot the man.

Then he nodded, and his stomach chilled into ice. Ryba had ordered her guards not to kill him. She was not aiming for the defeat of the Lornians. She wanted to keep the Lornian army whole and moving into the laser's range, and she was gambling on the laser and Nylan to destroy them totally.

"Damn you! Damn you ..." he muttered.

Suddenly, as the Lornian forces began to move again, to flow around the east end of the pike defenses, the remaining visible guards seemed to peel off the hillside behind the pike lines and ride westward toward the tower. The flow of arrows dropped to a few intermittent shafts.

Ryba reined up on the lower hillside, just above Nylan's bridge, and the remainder of the guards did also-not much more than half a score. Even if some guards remained in the rocks and in the ridge trees, casualties had been high-as usual.

Nylan hadn't seen Ayrlyn, not since breakfast. Why did he keep thinking about her-because she was one of the few that seemed to care about more than force?

Because he had come to care for her? He shook his head. The only thing he could do now was use the laser. His thoughts traced the power lines, and slowly smoothed out the fluxes and the swirls within the cells.

Slowly, slowly, the black and purple mass on the hillside continued to move, mostly westward, holding to the high part of the ridge slope, although a lobe offerees seemed to swing downhill.

Nylan let his senses settle into the laser, let himself feel the equipment again, as his eyes and senses also measured the hillside, and he took a deep breath. More than a third of the attackers remained shielded by the curve of the hill.

"Why is he waiting?" whispered a voice. "Leave him alone. He's got to get them all at once. Too many are hidden by the slope of the hill," hissed Huldran. As the sweat dripped from his forehead, and he absently brushed it away from his eyes, Nylan continued to watch, to sense. As the dark forces swelled and surged across the hillside toward the thin line of guards, he waited.

Finally, as he tasted salt and blood, he triggered the laser, and the beam flared, and spread into a cast of light that did nothing, just sprayed reddish light across the advancing Lornians.

"What's with the laser?" snapped Huldran. "We've got power."

"The wizards. They've got shields." Nylan extended his senses toward the focal point of the shields, stepping toward Huldran as he did. "Ease it right, more, more. Hold it there!"

White-faced, Huldran helped him ease the laser eastward.

The focal change failed to help, and another flare of light lit the hillside, even as the Lornian forces reached a point less than two hundred cubits from Ryba and the guards.

"Shit!" He could sense the interlocked shields of the two wizards on the hillside, and his mind and fingers tried to tighten the focus of the beam, to swing it right against those red-white shields.

The energy in the firin cells seemed to build, and Nylan could sense the surging power, surges with far more energy than those cells could have possibly contained, as well as the invisible hands of the white wizard, probing, jabbing.

The engineer concentrated, ignoring the nearing hoofbeats, ignoring the raging chaos in the power cells behind him, trying to focus his energy and order into the thinnest, sharpest needle of order and power.

The white shields pulsed, and the needle halted. Nylan concentrated harder, and the black needle probed at the reddish-white shields, narrowing, narrowing.

Nylan squeezed all the firin cell energy into that needle, driving it, hammering like a smith might hammer a needle-thin chisel against the joints in armor, relentlessly probing.

His eyes burned; his head felt like an anvil he was using, as though each thrust of the laser and the chaos somehow added by the white wizards rebounded back through him. His fingers were locked on the laser, as though held there by an electric current that flayed his nerves.

Still, Nylan hammered the needle against the white-red shields, forcing more and more power into that thrust, more and more chaos, more and more disruption, fighting the chaos backlash, and the lines of fire that felt as if they streamed from the white wizards and fell like lashes across his mind and body.

The shields of the white wizards wavered, and Nylan eased every erg of energy, chaotic and nonchaotic, smoothing it into an overwhelming tide of massed energy that cascaded against the pulsing white shields of the struggling Lornian wizards.

Something has to give... has to... has to, thought Nylan as he strained against the barriers that protected the Lornians.

CRRUMMMMMPTTT!.

Energy flared across the Roof of the World, and the sky shivered and the ground shook, and all three wizards were clothed in flame and chaos. At that moment, Tower Black, rearing mounts, guards, armsmen, and wizards were suspended in a timeless instant-bathed in fire, bathed in chaos, bathed in order.

CXXVI.

"LEAVE THE SIEGE engines at the bottom there," Sillek orders Viendros.

Viendros nods, as does Koric from beyond the Gallosian commander. If they can clear the field, then there will be time for the engines. If not, they will never get close enough to use them. The Gallosian rides back toward the lagging equipment.

' Arrows continue to fly from the trees on the left, and from the rocky jumble on the right. Sillek occasionally glimpses a slim figure retreating uphill as the Lornian force, under the two differently shaded purple banners, continues forward. The lancers advance almost in circles, keeping the horses moving at angles and turning abruptly to cut down on the ability of the angel archers to predict where the horsemen will be.

The foot keep their small shields raised, and many arrows either stick in the shields or bounce off. A fair number penetrate defenses and bodies, and several dozen bodies sprawl across the hillside behind the advance, as has been the case for kays.

"Keep moving!" Sillek orders. A flicker of something catches his eye, and he turns to see a squad of fast-moving angels riding toward the lead lancers. Almost before he can see what has happened, the angels have ridden farther uphill and into the dark cover of the high firs.

What Sillek can see are four or five riderless mounts and a slight slowing of the advance.

"Send a troop after them!" he orders Koric.

Koric looks puzzled.

"They'll do it again. After the next quick attack send twice that many riders after them."

"Ser..."

"I know. Most of them will get killed. But if we let them slow us down much more . . . we'll take even more losses from those damned arrows."

"We could turn back."

Sillek laughs. "I wouldn't last two days if I brought back an army and no victory."

"We could wait."

"Every day we'd lose another hundred troops. How long would they stand it?

How long before I had no army?" He raises the sabre for emphasis.

Koric nods reluctantly, then summons a messenger, who rides around the main body and to the vanguard.

Halfway up the long slope another squad of angels darts from the woods, slashing at the left flank of the lancers. Two squads of purple tunics race after them, catching one trailing rider, and slashing her from her mount.

The lancers slow, but do not stop as they near the trees, then vanish.

No one else attacks while the main force slogs another three hundred cubits uphill, while Viendros rejoins Sillek and Koric. Then a single mount staggers out of the trees, a purple figure sagging in the saddle. No other lancers return.

"Demons!" mutters Koric. 'They're worse than the Jeranyi."

"Far worse," agrees Viendros.

"Keep moving! Do the same thing if they attack from the flank again. One more attack, and we'll have the crest." Sillek turns to Terek. "Is the crest still clear, Ser Wizard? No pits in the ground?"

Terek bounces in the saddle, then answers. "No pits. I can sense that. The ground is solid, and clear except for some posts. They look like they started to build some fences. I saw them working on the fences days ago, but they're gone now. All that's left are the posts. Can your horsemen avoid them?"

"How big are they?"

"Like a tree trunk, shoulder-high. I would say ten cubits apart."

"That shouldn't be a problem." Sillek nods to Koric.

"We need to charge them, to cut them off," says Viendros.

Another squad of angel riders flashes down to less than a hundred cubits from the advancing lancers, reins up, where the riders draw short bows. The two dozen arrows almost wipe out the front row of horsemen, and the advance slows. A second angel squad appears on the right quarter, and also lets loose their arrows.

"Shit . . ." mutters someone. "No one shoots that hard from horseback."

Sillek wants to agree, but looks at Koric, then turns to Terek. "Are there any foot, any pikes, anything like that on the hill crest or beyond?

"Just the posts, ser."

"Koric," Sillek orders, "send all our lancers right after those riders. Clear the hill crest!"

"Yes, ser!" Koric nods, and beside him the trumpet sounds, and sounds again.

"Mine too, I think!" snaps Viendros, and he spurs his horse uphill.
