The platform rode the bars of metal. He followed them with his eye as they crossed the large cavern and vanished into the smaller tunnel ahead. Perhaps he would not have to go back to face any more of the killing things.

“Get up,” he ordered the girl, dragging her to her feet when she did not respond at once. “Where does this tunnel go to?” She looked first, in horror, at the wounded men dumped on the floor, then followed his pointing finger. “I don’t know,” she finally stammered. “Maintenance is not my work. Perhaps it is a maintenance tunnel.”

He made her explain what maintenance was before he pushed her to the platform. “What is the name of this?” he asked.

“It is a car.”

“Can you make it move? Answer without lying.”

Violence and death had drained her of hope. “Yes, yes I can,” she answered, almost in a whisper.

“Show me then.”

The car was very simple to operate. He put a new killing thing into it and sat beside her while she showed him. One lever made it go forward and back, and the further it was pushed the faster the car went. When it was released it returned to its middle position while a second lever did something that slowed and stopped the car. Chimal started them forward slowly, bending over when they entered the tunnel until he saw that there was a good deal of space between his head and the rock above. The lights, he had learned that word too, moved by faster and faster as he pushed on the lever. Finally, he had it jammed forward as far as it would go and the car raced at a tremendous speed down the tunnel. The walls tore by on each side and the air screamed around the transparent front. Watchman Steel crouched beside him, terrified, and he laughed, then slowed the speed. Ahead of them the row of lights began to curve off to the right and Chimal slowed even more. The curve continued, until they had turned a full right angle, then it straightened out once again. Immediately after this it began to start downward. The slope was gradual, but it continued endlessly. After some minutes of this Chimal stopped the car and ordered Steel out to stand against the wall.

“You’re going to leave me here,” she wailed.

“Not if you behave, I won’t. I just want to see about this tunnel — stand up straight, will you, as straight as you can. Yes, many Chimalman bless me, we’re still going down — to where? Nothing lies inside the Earth except the hell where Mixtec, the god of death lives. Are we going there?”

“I…I don’t know,” she said, weakly.

“Or you won’t tell me, it is the same thing. Well, if it is to hell, then you are joining me. Get back into the car. I have seen more wonders and strange things these last few days than I have ever dreamed, awake or asleep. Hell can be no stranger than them.”

After a period of time the slope flattened out and the tunnel went on, straight and level. Finally, far ahead, light filled the width of the opening and Chimal slowed and approached at a crawling pace. A much larger cavern gradually appeared, well lit and apparently empty. He stopped the ear short of it and approached on foot, pushing Watchman Steel before him. They halted at the entrance, peering in.

It was gigantic. A great room as big as the pyramid, carved from the solid rock. The tracks from their tunnel ran across the floor of the chamber and disappeared into another tunnel on the other side. There were lights along the sides and set into the ceiling, but most of the illumination poured in from a great hole in the roof at the far end of the chamber. The light looked like sunlight and the color was very much like the blue of the sky.

“’That just cannot be,” Chimal said. “We turned away from the valley when we left the place of the vultures, I’ll swear to that. Turned away into the living rock and went down — for a long time. That cannot be sunlight — or can it?” A sudden hope swept through him. “If we went down we could have gone through one of the mountains and come out in another valley that is lower than our valley. Your people do know a way out of the valley, and this is it.”

The light was growing brighter, he realized suddenly, pouring in through the hole above and shining down the long ramp that led up to it. Two tracks, very much like the ones that carried their car, only much larger, ran down the ramp and across the floor, to finally descend through an opening in the floor that was just as large as the one at the far end.

“What is happening?” Chimal asked as the light grew stronger, so brilliant that he could not look in the direction of the opening.

“Come away,” Steel said, pulling at his arm. “We must move back.”

He did not ask why — he knew why. The light blazed in and then the heat came, blasting and searing his face. They turned and ran, while behind them the light and heat, impossibly, intensified. It was scorching, a living flame playing about them as they threw themselves into the shelter of the car, arms over their eyes. It grew, light as hot as fire splashed about them — and then lessened.

After its passing the air felt chill, and when Chimal opened his eyes they had been so dazzled by the light that at first he could only see darkness and whirling spots of color.

“What was that?” he asked,

“The sun,” she said.

When he could finally see again it was nighttime. They went forward once more into the large chamber, now illuminated by the lights above and in the walls. The night sky of stars was visible through the opening, and Chimal and the girl walked slowly up the ramp toward it, until the ramp leveled off at ground level. The star? above came closer and closer, swooping down brighter and brighter until, when they emerged from the tunnel, they found themselves standing among them. Chimal looked down, with a fear that went beyond understanding, as a glowing star, a disk as big as a tortilla, crawled down his leg and across his foot and vanished. With a slow dignity, born of fear and the effort needed to control it, he turned and led the girl slowly back down the ramp into the welcoming shelter of the cavern.

“Do you understand what has happened?” he asked.

“I don’t know, I have heard about these things but I have never seen them before. Dealing with these matters is not my work.”

“I know. You’re a watchman and that is all you know, and you won’t tell me about that either.”

She shook her head no, her lips clamped shut in a tight line. He sat, pulling her down next to him, with his back to that opening and the inexplicable mystery of the stars.

“I am thirsty,” she said. “There is supposed to be emergency rations at these places so far distant. Those must be cupboards, over there.”

“We’ll look together.”

Behind a thick metal door were packages of rations and transparent containers of water. She showed him how to open a container and he drank his fill before handing it to her. The food was just as tasteless, and just as filling, as before. While he ate he was conscious of a great and overwhelming tiredness. In his mind as well as his body, because the thought of the sun passing close to him and the stars crawling at his feet was so inconceivable that it did not bear thinking about. He wanted to ask the girl more questions but now, for the first time, he was afraid to hear the answers.

“I am going to sleep,” he told her, “and I want to find you and the car here when I wake up.” He thought for a moment and then, ignoring her feeble bleatings and resistance, he took the box, on its chain of metal beads from around her neck, and weighed it in his hand. “What do you call this?” he asked.

“It is my deus. Please give it back to me.”

“I don’t want the thing, but I do want you here. Give me your hand.” He wrapped the chain around her wrist, and then about his own hand with the deus held inside against his palm. The stone looked hard but he did not care: almost as soon as he closed his eyes he was asleep.
