Seth sprinted along the tunnel until he emerged in a vast cavern. Heavy iron chandeliers hung from the high, vaulted ceiling, casting a diffuse glow across the room. Tall barriers of dark iron reached halfway to the ceiling, barring the way except for five gaps. There was no way to confirm that the iron walls were invisible to others. They sure looked solid to him.
Hooves clattered in the tunnel, and Seth slipped through one of the gaps into the labyrinth, putting a barrier between himself and the entrance to the cavern. He did not proceed far. If he was careful, the presence of the centaurs might work to his advantage. By following them at a distance, he could take the guesswork out of wandering the maze. He bounced on his toes, flexing his fingers, ready to run in case he had accidentally chosen the correct gap and the centaurs came his way.
Glancing at the ground, he noticed that the iron walls cast no shadows. The mellow light from the chandeliers dispersed evenly, with no interference. And in that moment he realized his problem.
If the walls of the maze were invisible to the centaurs, the iron barriers would do nothing to conceal him from their sight!
From the sound of the approaching hoofbeats, the centaurs were almost through the tunnel. Seth raced out of the maze and hurried to one side of the tunnel mouth, standing as close to the wall as he dared. The light from the chandeliers was mild. Was it dim enough for his shade-walking ability to function? Probably not. His mind scrambled. He had gotten only a quick glimpse of the oncoming centaurs. Their wheelbarrows were big, almost the size of wagons. They were piled high with food. What if he tried to hitch a ride as the first one emerged? If he stayed low and kept in the front of the wheelbarrow, the centaur pushing it might not see him.
The first centaur had almost reached him. He could hear the creak of the first wheelbarrow's wheel and the unhurried clop of hoofbeats. As the wheelbarrow nosed out from the tunnel into the cavern, Seth hopped in front of it, sprang inside, and burrowed down as low as he could. He found his cheek nestled against something soft and covered with coarse hair. It took a moment to realize that it was the ear of a pig. In fact, the entire wheelbarrow was stacked with freshly slaughtered hogs, many of them almost Seth's size!
The dead pigs were piled high enough that Seth could not see the centaur pushing the wheelbarrow. He wriggled down as far as he could. Who knew if this wheelbarrow would remain in the lead, or what might happen after they negotiated the maze? He had to try to bury himself. The pigs were heavy and did not leave much wiggle room, but Seth managed to partially conceal his body.
The wheelbarrow entered the maze, moving ahead smoothly, turning right, then left, then veering slightly back to the right. Seth tried hard to pay attention to each turn. If he managed to avoid discovery, he would have to return through the labyrinth on his own. He wondered how the centaurs moved so surely if they could not see the walls. Either they had memorized the route with startling precision, or they were somehow navigating by secret markers, perhaps on the ground or ceiling. Focusing on the iron walls from his position in the wheelbarrow, Seth soon became disoriented by the many turns. He found that if he contented himself with watching the walls peripherally and studied the ceiling instead, he retained a better sense of where they were in the room.
They followed a serpentine route through the maze for longer than Seth liked. He tried to keep count of how many times they doubled back, approximating their position by the stationary chandeliers. At length they arrived at an open area toward the middle of the cavern. In the center of the broad space stood a stone about the size of a refrigerator. The mountain troll sat near the stone, a huge, hunched creature bristling with spikes. His back was to the centaurs, but Seth could see his thick limbs and tough hide. Seated, the troll was at least three times taller than Seth. A chain with links as thick as Seth's waist connected the creature to a huge metal ring in the ground.
Suddenly the wheelbarrow was upended, and Seth found himself participating in an avalanche of dead pigs. Lying beneath a heavy pile of swine, he heard other wheelbarrows dumping their contents. The downside of his position was that the pigs were crushing him. The upside was he could still somewhat breathe and he was utterly hidden from view.
He heard the centaurs retreating. No words were exchanged with the titanic troll.
As the hoofbeats faded, heavier footsteps drew near. The chain clanked weightily. Seth had a vivid image of the troll cramming dead pigs into his mouth, and a human boy along with them. Seth tried to squirm, but the weight of the hogs was too great. He was pinned.
"Hello?" Seth called, not raising his voice too much. The troll stopped moving. "Hello?" Seth tried again.
Seth heard a couple of nearby footfalls, and the porcine press began to lessen. A moment later, Seth had been uncovered. This was his chance. He had to act friendly. Show no uncertainty. He rose to his knees.
The troll towered over him, yellow eyes glaring down. His flesh was thick and folded like the hide of a rhinoceros. The cruel spikes protruding from his shoulders, forearms, thighs, and shins ranged from the length of a knife to the length of a sword. The brute smelled like a monkey house.
"Hi," Seth said brightly, waving and smiling. "I'm Navarog. How are you?"
The troll snorted and grunted at the same time. The exhalation intensified the funky odor.
Seth stood up shakily. "I'm a shadow charmer. An ally of the night. Trolls are my favorite. You sure are big. Look at those spikes! You must be the strongest troll ever!"
The troll smiled. Four of his bottom teeth jutted up almost to his nose.
"I figured we'd become friends," Seth continued, stepping away from the dead swine. "How do you like it here?"
The troll shrugged. "Why you in food?" The words came out like a controlled belch.
"I'm working on a trick. I'm going to play a joke on the centaurs."
The troll sat down, picked up a hog, and stuffed the entire animal in his mouth. Bones crunched sickeningly as he chewed. "Me like jokes."
"I have a really funny one planned. I missed your name."
The troll swallowed noisily and wiped his lips. "Udnar." He picked up another hog by the rear legs, dangled it above his upturned mouth, then dropped it in. "Pigs good."
"I like pigs too."
Udnar grabbed a third pig and held it out to Seth. "Take."
"I can't," Seth apologized. "I ate one on the way in, so now I'm full. I'm not big like you."
"You take no ask?" the troll accused, voice rising.
"No, um, not one of yours. I brought one from home. A little one. My size."
