“Come.” Pewter-skin used sounds, touch, and gesture to convey his meaning. “You speak words that poison. The others turn away from you. We look away from the thing that offends us. But I think I first will show you. I think you are ignorant.” The skrolin unrolled and waddled away.
Walking made pain lance through his temple with every footfall, but he followed as the chamber narrowed on all sides. He walked in a crouch until the ceiling opened up and the walls fell away to a larger chamber. Pewter-skin led him to a low opening, where he crawled on hands and knees over coarse rock then cautiously down a steep incline to a larger chamber ribbed with veins of a mineral he could not identify. A well-worn path took them along a branching tube, past two shafts that plunged into darkness, three stone pillars with rubble heaped to one side, and four branches forking off the main corridor whose ceilings curved so low he could never have hoped to squeeze through them. The ceiling in the main tunnel remained high enough that he did not hit his head, and finally, where the floor ramped up, Pewter-skin scuttled through an opening and he scrambled up behind him, scraping his knees and palms although the soles of his feet were so callused that not even the rough rock edges could cut them. The ceiling and walls opened up with startling speed to a much larger cavern, and he sucked in a breath in surprise, inhaling a smell as thick as bubbling yeast in a closed, warm room filled with rising bread.
White growths, like huge mushrooms, grew in tidy rows and discrete clumps across the floor of the cavern. That powerful smell pervaded the air. He coughed, blinking back the stinging aftertaste of putrefaction that made his eyes water and his tongue turn dry. Life cannot grow from dead rock.
Corpses lay in stages of decay. The freshest bloomed heavily with a funguslike mass; elsewhere, a few last sprigs decorated bones as the spongy fungus devoured the last shreds of the living.
Pewter-skin plucked a handful of the white stuff and ate it.
“We live in a trap. Clavas keeps us alive. The empty ones give nourishment to the clavas. So we trade silapu for the empty ones. We cannot eat the silapu, though some say we could in the time of the city. In that time, we were a strong and clever people, handsome and crusted with growths. Now we are sick and dying, even the free ones.”
“Where are the free ones? Why are you in a trap?”
“Come.” Pewter-skin beckoned.
He followed through the garden of corpses and bones and into a tunnel streaked with discolorations that glittered as he passed. By the glow of his armband he picked out veins and crystals grown into the rock. Sparkling grains slipped under his feet. Tunnels branched out to either side and crossed over and under where shafts pierced down or up until their path bewildered him and he knew himself lost. Pewter-skin led the way unerringly, and after an interminable time that might have lasted the length of a hymn or a hundred years they squeezed between twin pillars and he stared up in wonder. The ceiling and walls of this wide cavern shone where the light reflected off it, although the walls faded to darkness not so many steps away. The floor was unusually level. Here the skrolin had used scoured bones to build a strange architecture: a pyramid of skulls; an archway woven of thighbones cunningly trimmed and threaded together; a wharf constructed of linked rib cages; shoulder blades and pelvic bones arranged in a crude miniature temple or governor’s palace.
“This is the tale of the city,” said Pewter-skin. “We try to remember.”
“Why can’t you remember?” he asked.
“The tale is told from one to another through many lives, but we forget if it is true, or if it is false.”
“The trap you speak of? Is that a true tale, or a false one?”
“Ah!” The sound cut, edged with rage, resignation, and sorrow. “Come. Come.”
A trail bifurcated the bone city, leading them past the eerie structures to the far side where ceiling met floor. There, at the joining, a narrow passage ramped down.
“This is the trap.”
He smelled water. He got down on hands and knees and crawled forward into a tunnel far too low for him to stand upright. He hadn’t gone more than a body’s length when his hands met moisture. He touched liquid to tongue, spat it out, and wormed back out.
“It tastes like sea water.”
“Such water is poison to us. Through that tunnel many watches ago we come, thirty of us, seeking luiadh. The earth shivers. The feet of the wise ones far to the north shift and tremble. The waters rush in to trap us here where the tunnels run in a circle. We cannot get out.”
He had to sort through this speech. “These tunnels you live in now are a dead end. The tunnel you came in through filled with water because of an earthquake. Now you are all trapped here.”
