With a meaningful glance, Seth and Kendra communicated what they both realized. Nobody was coming to help them.

The six dark dryads approached at superhuman speed, low and swift like jungle cats. Beams of blackness rained down from the oncoming dark fairies. The shadowy streaks did not affect Kendra, but Seth yelped as they struck him, darkening his clothes and turning his flesh invisible wherever they struck. Some light fairies feebly rose to intercept the dark ones, but most were swiftly transformed.

"Run, Kendra," Seth urged, an invisible patch spreading across the side of his jaw.

"Not this time," Kendra said. The dark dryads were too quick for her to have any hope of escape.

The dark dryads closed in fast, reddened eyes glinting, thin lips parted to reveal hideous fangs. A dark dryad snatched Seth, hoisting him into the air with a single arm and plunging her teeth into his neck. He thrashed, but the gray dryad held him firmly, and a moment later he was invisible.

The six dryads formed a ring around Kendra, seeming somewhat hesitant to engage her. Kendra held up the pebble threateningly. Wincing, they fell back a couple of paces. Face scrunched into a mask of determination, one of the dark dryads sprang forward, grasping at Kendra. As soon as her gray fingers closed around Kendra's wrist, her entire aspect transformed. Pale, lank hair became curly and dark.

Gray flesh bloomed to full health. Looking startled, a tall, beautiful woman staggered away from Kendra, turning to face the dark dryads.

Kendra lunged at another dark dryad, swatting her surprised target on the arm as the dryad stumbled uncertainly backward. Instantly the dryad had fiery red hair, a creamy countenance, and flowing robes. The gorgeous dryad Kendra had first restored tackled a dark dryad, pinning her to the ground. Kendra raced over and patted the dark dryad on the cheek. Suddenly the dark dryad became a tall Asian woman.

Invisible fingers closed around Kendra's wrist, and Seth reappeared. "I could have done that faster if you would hold still," he panted, looking unsteady.

"No time," Kendra said, charging after a fourth dark dryad, feeling almost like she was on a playground. She was It, and this was a high-stakes game of tag. The other three dark dryads were now in full retreat. Seth staggered along behind Kendra.

The dryad Kendra was chasing kept stretching her lead, so Kendra paused to consider a better move. All around the cart, shadowy fairies were turning huge quantities of fairies dark. Kendra turned her attention elsewhere-fairies were too small and quick for her to lose time trying to touch them. The good dwarfs had caught up to the skirmish and were using their hammers to drop minotaurs. The dark side had reinforcements as well-goblins and dark dwarfs.

Increasingly, dark fairies were joining the battle to transform satyrs and hamadryads.

Seth grabbed Kendra's arm. "Trouble."

She saw the problem a moment after he said it. The fog giant who had been knocked unconscious had reawakened and was drowsily crawling toward them. Kendra had no idea how her light talisman would affect him since he was not in a darkened state-as with a goblin or a minotaur, darkness was simply part of his nature.

As Kendra started backing away, the giant sprang, diving at her with unavoidable quickness, his huge hand closing around her waist. Blinding light flared for an instant, and the giant flopped away from her, convulsing, unconscious once more, his smoking palm seared and blistered.

The flash of light left the surrounding dark creatures temporarily dazzled. Kendra dashed to where the darkened version of Broadhoof was trying to sink his teeth into Cloudwing. With a valiant effort, Cloudwing wrenched Broadhoof toward Kendra, and she slapped him on the flank. Instantly Broadhoof was restored.

Cloudwing showed Kendra a rapidly spreading maroon wound on his arm, and she healed it with a touch. "Remarkable," he approved.

The fighting continued, but the dark creatures were now doing their best to remain far from Kendra as they relentlessly transformed satyrs, dwarfs, and dryads. Hugo had the giant he had been brawling in a chokehold, and the tremendous brute finally collapsed. The three dryads Kendra had transformed were helping Patton, Lena, Coulter, and Lizette fight off a group of dark hamadryads. Half of Patton's face was invisible, along with one hand.

Kendra and Seth raced to help, and the dark hamadryads withdrew, shifting their attention to easier prey.

Patton embraced Kendra, instantaneously becoming fully visible. "You're doing well, my dear, but the dark creatures are changing too many of our allies too quickly. We have to get to the tree before no allies remain."

"I know the way," offered the first dark dryad Kendra had transformed. "My name is Rhea."

"Hugo, Broadhoof, Cloudwing!" Patton called. The golem and the centaurs hurried to them. "Take us to the tree. We'll be following Rhea."

The two other dryads Kendra had transformed resolved to stay behind and help with the battle. Lizette, her autumnal robes torn, opted to accompany Rhea.

Broadhoof swung Kendra and Seth onto his back. Cloudwing bore Patton. Hugo picked up Coulter and Lena.

"Lead on," Cloudwing proposed.

Rhea and Lizette ran in front, with Broadhoof behind them, Hugo on one side, and Cloudwing on the other. Broadhoof cantered so smoothly that Kendra had no fear of falling. She held her pebble high, and dark creatures lunged out of the way to let them pass. Glancing back, Kendra saw the two dark centaurs and several dark dryads following them at a distance.

Moving with astonishing speed, Rhea dashed into the woods from which the dark creatures had emerged. The trees were dense, but there was little undergrowth. Kendra held tightly to the pebble as tall trunks sped by on either side.

Before long, they halted abruptly at the rim of a bowl-shaped valley. To Kendra, it looked like they were peering into a crater. A pool of sludge simmered in the middle of the deep depression, the steaming black surface occasionally disturbed by slow bubbles. The only plant in the rocky valley was a gnarled tree beside the lake of tar. Leafless and contorted, the tortured tree was even darker than the seething sludge.

The dryads jumped down the steep side of the valley, and the centaurs followed. Kendra leaned back, squeezing with her legs, her stomach in her throat, as Broadhoof plunged down the sheer slope, his hooves guiding their fall more than propelling them forward. The slope leveled out, and miraculously she and Seth remained astride the centaur, whose hooves now clopped noisily over the rocky ground.

From hiding places among boulders and cavities in the ground emerged three dark centaurs, four dark dryads, several armor-clad hobgoblins, and an obese cyclops wielding a poleax. The black tree was not far ahead-maybe fifty yards. But many dark creatures barred the way.

"Huddle close to Kendra!" Patton urged.

Cloudwing, Broadhoof, Rhea, Lizette, and Hugo skidded to a stop.

Hoofbeats sounded behind them as two dark centaurs plunged down the valley wall, accompanied by more dark dryads. "Her touch will undo your darkness," Stormbrow warned the others. "Not mine," the fat cyclops bellowed.

"She'll burn you," Stormbrow cautioned. "Her touch overcame a giant."

The dark creatures stirred uncomfortably. The Cyclops appeared uncertain.

"Have no fear," a cold, penetrating voice rang across the valley.

All eyes turned to the lip of the valley beyond the tormented tree, where a spectral woman bundled in shadow floated down from the rim, her robes flowing strangely, as if underwater.

"Oh, no," Seth breathed behind Kendra.

"The girl can do no lasting harm here," Ephira continued. "This is our domain. My darkness will quench her spark."

"Come no closer, Ephira," Patton shouted. "Do not interfere. We bring release from the bleak prison to which you have been confined."

Ephira gave a chilling, joyless laugh. "You should not have meddled here, Patton Burgess. I am not in need of rescue."

"That will not stop us," he replied in a softer voice.

"You cannot possibly imagine the depth of my power," she purred, gliding ever closer.

"Too much darkness can be blinding," Patton cautioned.

"As can too much light," she replied. She now floated protectively in front of the black tree.

"A fact you will soon appreciate as never before." Patton nudged Cloudwing with his heels. "Onward! Hugo, flatten our opponents!"

Hugo set down Lena and Coulter and rushed the blubbery cyclops. The oaf embedded his poleax in Hugo's side before the golem seized him and hurled him into the lake of tar. Rhea and Lizette began battling dark dryads, driving them away from the centaurs. Hooves hammering the stony ground, Cloudwing and Broadhoof galloped forward, ramming enemies aside. Patton motioned for Broadhoof to loop around while he charged Ephira.

In order to impede both centaurs, the spectral woman glided sideways, dark tendrils of fabric flowing out in either direction. As soon as the fabric reached Cloudwing, his legs buckled and he crashed to the rocky ground, snapping his right foreleg and his right arm. Patton sprang free, rolling deftly to his feet. An instant later, limping awkwardly, Cloudwing arose, taller, thicker, his flesh maroon.

Another grasping fabric tentacle tangled around one of Broadhoof's front legs. Grunting, the centaur clattered to an abrupt stop. Sweating and groaning, Broadhoof swayed, but remained standing. He began to transform as Cloudwing had, but then the effect faded. Kendra felt the pebble warming her palm. Beneath her, Broadhoof felt warmer as well. Her hand glowed red. Brilliant beams of light escaped between her fingers. The creatures of darkness fell back. Broadhoof quivered beneath her, temporarily darkening and then returning to normal.

"Ephira can't change him," Seth whispered.

More tendrils of dark fabric snaked forward to entangle the centaur. The stone was becoming uncomfortably hot.

Ephira looked grimly focused. Broadhoof's breathing became increasingly rapid. He trembled, muscles clenched in anguish. Dimly Kendra was aware of Hugo wrestling with the dark creature Cloudwing had become.

Aware of the brightening pebble, Kendra opened her hand, flooding the area with harsh white luminance. The dark creatures retreated further, yowling, hands raised to their eyes. Ephira hissed, grasping Broadhoof with even more shadowy tentacles.

Hands balled into fists, tendons standing out on his thick neck, Broadhoof released a full-throated cry of agony.

The centaur folded his legs and collapsed, slumping lifelessly to the earth. The stone no longer glowed. Broadhoof no longer breathed.

Ephira's flowing fabric slithered free from Broadhoof and reached for Kendra. Pushing away from the dead centaur, Kendra tried to avoid the fabric, but one serpentine ribbon brushed against her. The instant the fabric touched her, the stone flared brightly, and the length of fabric vanished in a blaze of white flame.

Ephira shrieked and reeled as if she had been physically struck. The other tendrils of fabric retreated from Kendra and Seth.

"Kendra!" Patton called adamantly. "The stone!"

Patton stood not far from Ephira, considerably closer to the black tree than Kendra. Trusting his judgment, she tossed the stone to him and he caught it with both hands. Coulter and Lena were rushing to catch up to Patton. Hugo heaved the crippled, darkened Cloudwing into the lake of tar.

Scowling, Ephira raised a hand palm outward. Kendra felt a wave of fear wash over her, and noticed that both her skin and the stone that Patton held began to glow. She could feel the fear trying to take hold, but the emotion kept burning away before it could really penetrate. Lena and Coulter were no longer running. They stood immobilized, trembling. Coulter dropped to his knees.

Patton was also trembling. He took a few stiff steps. Flowing lengths of fabric reached out for him. Seth ran to him. Arriving an instant before the fabric, Seth seized Patton's hand.

Pinching the pebble between his thumb and forefinger, Patton touched the stone to the nearest fabric tentacle. With a fiery flash, the fabric disappeared.

Ephira screeched, once again retracting the other long strips of fabric. Coulter arose and Lena once again dashed forward toward Patton. Holding the pebble up menacingly, and keeping hold of Seth, Patton raced around Ephira. The shadowy woman glared at Patton with impotent rage, pivoting to follow him with her eyes.

Patton released Seth and gestured for him to return to Kendra. Seth hesitantly retreated. Ephira closed her eyes and raised both palms. Lena came to a stop again, and Kendra glowed brightly. Patton advanced as if weighed down. Paralysis seemed to be setting in, but he kept his legs plodding toward the tree. When he was within ten feet of the black tree he raised the hand with the pebble as if aiming a dart.

That was the first time Kendra noticed the nail near the base of the trunk. Ephira opened her eyes and howled. With a gentle motion, Patton tossed the pebble. It spun through the air on a perfect trajectory to ping against the nail. As the glowing pebble drew near, it abruptly changed course, soaring away sideways and bouncing over the rocky ground toward the lake of tar.

"What happened?" Seth yelled in disbelief.

"They repelled each other," Kendra moaned.

Dark fabric stretched from Ephira toward where Patton knelt hunched near the dark tree. Arms moving jerkily, Patton removed a small box from a pocket and opened it. Three fairies zipped out. A moment later the tendrils of fabric twined around Patton and he vanished.

Dark dryads and hobgoblins mobbed Hugo, hacking at him with swords and beating at him with cudgels, attempting to drive him into the tar. Hugo resisted them staunchly, occasionally landing a blow of his own.

The dark centaur Stormbrow galloped along the edge of the asphalt lake, clearly heading for the pebble. Shiara reached the stone first. When she touched it, her natural glow increased a hundredfold. Gleaming blindingly, she fell to the ground, apparently having fainted. The other two fairies attempted to lift the pebble and also passed out, shining with eye-watering brilliance.
