Maya talked it over with Michel and Kasei, never even glancing at Spencer. Michel and Kasei were agreeable, and finally she nodded. “All right. We’re off south. Come down as quickly as you can.”

They drove by night and slept by day, in their old pattern, and in two nights made their way across Echus Chasma to Tharsis Tholus, a volcanic cone on the northern edge of the Tharsis bulge.

There a Nicosia-class tent town called Tharsis Tholus was located on the black flank of its namesake. The town was part of the demimonde: most of its citizens were living ordinary lives in the surface net, but many of them were Bogdanovists, who helped support Bogdanovist refuges in the area, as well as Red sanctuaries in Mareotis and on the Great Escarpment; and they helped other people in the town who had left the net, or been off it since birth. The biggest med clinic in town was Bogdanovist, and served many of the underground.

So they drove right up to the tent, and plugged into its garage, and got out. And soon a little ambulance car came and rushed Sax to the clinic, near the center of town. The rest of them walked down the grassy main street after him, feeling the roominess after all those days in the cars. Art goggled at their open behavior, and Nirgal briefly explained the demimonde to him as they walked to a café with some safe rooms upstairs, across from the clinic.

At the clinic itself they were already at work on Sax. A few hours after their arrival, Nirgal was allowed to clean up and change into sterile clothes, and then to go in to sit with him.

They had him on a ventilator, which was circulating a liquid through his lungs. One could see it in the clear tubes and the mask covering his face, looking like clouded water. It was an awful thing to see, as if they were drowning him. But the liquid was a perfluorocarbon-based mixture, and it transferred to Sax three times as much oxygen as air would have, and flushed out the gunk that had been accumulating in his lungs, and reinflated collapsed airways, and was spiked with a variety of drugs and medicines. The med tech working on Sax explained all this to Nirgal as she worked. “He had a bit of edema, so it’s kind of a paradoxical treatment, but it works.”

And so Nirgal sat, his hand on Sax’s arm, watching the fluid inside the mask that was taped to Sax’s lower face, swirling in and out of him. “It’s like he’s back in an ectogene tank,” Nirgal said.

“Or,” the med tech said, looking at him curiously, “in the womb.”

“Yes. Being reborn. He doesn’t even look the same.”
