Without warning, the raft ran aground, squishing against the muddy, reedy bank. "Here we are," Nero whispered. "Move away from the water. Keep to the shade. Go swiftly. The hour grows late."
"Thanks for the ride," Seth whispered back. "See you soon."
Seth sprang from the boat, reeds rustling as he landed. He froze, crouched, listening. When no furious centaurs descended on him, he crept forward, staying low and stepping with care. Up ahead, through the trees, Seth began to discern the wavering glow of firelight. He advanced toward the light.
The foliage at the edge of the swamp soon gave way to evergreens. There was little undergrowth, so Seth scurried from tree to tree until he obtained a view of a large hill. The monstrous silhouette of a colossal stone dominated the foreground. Cressets and torches burned on the hill, shedding warm auras of radiance and backlighting the megalith.
Seth took out his compass. He could barely read it by the wavering light of the distant flames. He found north and promptly determined which of the megaliths was the southernmost. It was the second monolith to the right.
By no means did the torches brighten the entire hill. The jittery flames merely provided periodic illumination. At first the area appeared deserted. Then Seth began to spot centaurs spaced around the base of the hill, lurking in pockets of darkness away from the flaming cressets. He counted three, and assumed there would be more on the far side of the entrance, Rather than cluster around the southernmost stone, the centaurs had opted to spread out, as if simply guarding the hill. Their positions showed no preference to any particular megalith.
Clearly the centaurs didn't want the placement of their sentries to give away the position of the entrance. The deployment could work to his advantage. It gave him some room to work with. The level area between the evergreens at the base of the hill lacked cover. But it was dim. If his ability worked as Nero had described, he should be able to slink forward, then sneak along the bottom of the hill to the southernmost megalith. If not, he would be apprehended the instant he crawled out from behind the trees.
Dropping to his hands and knees, Seth inched forward, eyes on the nearest centaur. The guard stood perhaps a hundred feet away, brawny arms folded. The cover of the trees was soon well behind Seth. At times, the centaur seemed to stare right at him; then the brooding face would turn away. So far, so good.
Seth had no idea how much movement might destroy his dimness and attract attention, so he advanced very slowly. He crawled toward the nearest megalith, stomach tight with worry. Once he was close enough to the huge stone, it would interrupt all lines of sight from the hill. Too bad the southernmost stone was still over a hundred yards away.
When he reached the megalith, Seth stood up, sweaty despite the cold. He started working his way around the gigantic stone to peek at the hill again. Just as part of the hill was coming into view, the ground began to vibrate.
Seth froze. The vibration grew into a trembling, the trembling into a quaking, and the megalith beside him began to rise. Seth fell flat and crawled on his belly toward the hill. He squirmed to the nearest bush and then held still, ready for a centaur to shout an alarm.
Abruptly the quaking stopped.
Glancing over his shoulder, Seth saw that the bottom of the stone was hovering about five feet in the air. The megalith appeared to have risen about fifteen feet, the lowest ten feet of the stone having been underground. A dark pit yawned where the colossal stone had rested. Slowly, the megalith began to drift sideways.
The clock was ticking.
Seth had one hour to get through the entrance, navigate the maze, befriend the troll, claim the horn, return through the maze, and exit unnoticed.
Rising to his knees, Seth surveyed the vicinity, making certain the centaurs had retained their previous positions and scanning for any sentries he may have missed. He saw no surprises. The nearest centaur was up the slope about thirty feet. From this angle, a torch farther up the hill made his outline obvious.
Seth began crawling along the base of the hill, trying to keep bushes and hedges between himself and the guards. Several times he had to creep across open spaces. He proceeded slowly, and no alarm was raised.
His most nerve-racking moment came as he crept across empty ground not fifteen feet in front of a sentry. He was halfway across the shadowy gap when his knee came down on a dry twig, snapping it clean. Seth halted, head down, muscles locked in panic.
From the corner of his eye he saw the centaur plodding forward to investigate. His only chance was to remain still as a statue and hope he appeared much less visible than he felt. The centaur halted immediately beside him. Had Seth stretched out a hand, he could have touched his hoof. Seth concentrated on breathing softly. Might the centaur smell him? His arms began to feel wobbly from holding the same position.
The centaur finally backed away, returning to his station in the gloom below a tall hedge. Seth slunk forward, careful to move in silence.
At last, heart pounding, Seth came even with the pit belonging to the southernmost megalith. The huge stone had now floated completely out of the way. To reach the pit, once again he would have to traverse an expanse of unshielded ground.
Clenching his tongue gently between his teeth, Seth crawled forward, resisting the temptation to hurry across the bare area. He was well away from any cover when he heard approaching hoofbeats. He slowly turned his head. Several centaurs were approaching from his left, bearing torches and pushing enormous wheelbarrows heaped with food.
Behind him, a centaur whom Seth had failed to notice emerged from hiding. The centaur called out in a series of grunts, gargles, and whinnies. The centaur language sounded more like horse noises than human speech.
The oncoming centaurs responded to the greeting by trumpeting strange replies of their own. They were heading toward the entrance to the maze.
As the centaur behind Seth cantered over to greet his comrades, their eyes were on each other. Seth decided it might be the only decent distraction he would have before they reached him, so he rose, sprinted to the pit in a low crouch, and dove blindly into it.
Fortunately the walls of the pit were not sheer. Seth rolled to the bottom. Relieved once again to hear no cries of alarm, he regained his feet. A rounded entryway dominated one side of the pit. It had no door, so Seth dashed inside.
Below his feet the ground became firm and smooth. The long tunnel sloped steadily downward, plunging into and under the hill. Not wanting to accidentally brush against a wall, Seth switched on his flashlight, cupping a hand over the end to reduce the glare. Before long, he noticed a bluish radiance up ahead and switched off the flashlight.
