He went to the seat in the rear, stretched out on it with his face to the cushions, and appeared to fall instantly asleep, Mark sat in the driver's chair, careful to touch nothing, both fascinated and repelled by the world outside. The car continued unerringly down the center of the road at a high speed, slowing only when it had to burn away obstructions. It must have utilized radar or other sensing devices, for a_ sudden heavy rainstorm did not reduce its speed in the slightest. Visibility was only a few feet in the intense tropical downpour, yet the car moved on, speed unabated. It did slow, but only to burn away obstructions, and smoke and steam obscured all vision. Then the storm stopped, as quickly as it began. Mark watched until he began to yawn, so then, like Arinix, he tried to rest. At first he thought he could not possibly sleep, then realized he had. Darkness had fallen outside, and the car still hurried silently through the night.
It was just before dawn when they reached their destination.
The building was as big as a fortress, which it resembled in more ways than one. Its walls- were high and dark, featureless, streaked with rain. Harsh lights on all sides lit the ground, which was nothing more than sodden ash. Apparently all plant life was burned before it could reach the building and undermine it. The road led directly to a high door that slid open automatically as they approached. Arinix stopped the vehicle a few hundred yards short of the entrance and rose from the controls.
"Come with me. This machine will enter by itself, but we shall walk. There is no solar radiation now, so you may, see my world and know what is in store for all the others."
They stepped out into the damp airlessness of the night. The car pulled away from them, and they were alone. Rivulets of wet ash streaked the road, disappearing in runnels at either side where the waiting plant life leaned close. The air was hot, muggy, hard to breathe, seemingly giving no substance to the lungs. Mark gasped and breathed deeply over and over again,
"Remember," Arinix said, turning away and starting for the entrance, "this is night, midwinter, before dawn, the coolest it will ever be here. Do not come in the summer."
Mark went after him, aware that he was already soaked with sweat, feeling the strength of the enemy in the sky above, which was already touching fire to the eastern horizon. Though he panted with the effort, he ran and staggered into the building and watched as the door ground shut behind him.
"Your work now begins;" Arinix said, leading the way into a now familiar brown room. Mark got his breath back and wiped his streaming face while they made their swift journey to the world line named Iroquois,
"I will leave you here and will return in twenty-four hours-for your report on the situation. We will then decide what must
"Just a minute-I don't know anything that is happening here. You will have to brief me."
"I know nothing of this operation, other than what I have told you. The Sixim there should have complete records and will tell you what you need to know. Now, leave. I have my own work to do."
There was no point in arguing, Arinix gestured again impatiently, and Mark went through the door, which closed with a ponderous thud behind him. He was in darkness, cold darkness, and he shivered uncontrollably after the heat of the world he had just left.
"Sixim, are you there? Can you turn on some lights?"
There was the sudden flare of a match in answer, and in its light he could see an Indian lighting an ordinary kerosene lamp. He wore thong-wrapped fur leggings and a fringed deerskin jacket. Though his skin was dark, his features were Indo-European; once the lamp was lit, he stood by it, un-moving,
"You are the Sixim," Mark said.
"I am."
"What are you doing here?"
"Awaiting instructions."
These creatures were as literal-minded as computers- which is probably what their brains were. Mark realized he had to be more specific with his questions, but his teeth were chattering with cold, and he was shivering hard, which made it difficult to think.
"How long have you-been waiting?"
"Twelve days, fourteen hours, and-"
"That's precise enough. You have just been sitting here in the dark without heat all that time! Do you have a way of heating this place?"
"Yes."
"Then do it, and quickly… and let me have something to wrap around me before I freeze."
The buffalo-skin robe made a big difference, and while the Sixim lit a fire in a large stone fireplace, Mark looked around at the large room. The walls were of logs, with the bark still on, and the floor bare wide boards. Crates were piled at one end of the room, and a small mound of skins was at the other. Around the fire, it was more domestic, with a table and chairs, cooking pots, and cabinets. Mark pulled a wooden chair close and raised his hands to the crackling blaze. Once the fire was started, the Sixim waited stolidly again for more orders.
