But red Mars was gone, and gone for good. Soletta or not, ice age or not, the biosphere would grow and spread until it covered everything, with an ocean in the north, and lakes in the south, and streams, forests, prairies, cities and roads, oh she saw it all; white clouds raining mud on the ancient highlands while the uncaring masses built their cities as fast as they could, the long run-out of civilization burying her world.

Part Two

Areophany

To Sax it looked like that least rational of conflicts, civil war. Two parts of a group shared many more interests than disagreements, but fought anyway. Unfortunately it was not possible to force people to study cost-benefit analysis. Nothing to be done. Or— possibly one could identify a crux issue causing one or both sides to resort to violence. After that, try to defuse that issue.

Clearly in this case a crux issue was terraforming. A matter with which Sax was closely identified. This could be viewed as a disadvantage, as a mediator ought ideally to be neutral. On the other hand, his actions might speak symbolically for the terraforming effort itself. He might accomplish more with a symbolic gesture than anyone else. What was needed was a concession to the Reds, a real concession, the reality of which would increase its symbolic value by some hidden exponential factor. Symbolic value: it was a concept Sax was trying very hard to understand. Words of all kinds gave him trouble now, so much so that he had taken to etymology to try to understand them better. A glance at the wrist: symbol, “something that stands for something else,” from the Latin symbolum, adopted from a Greek word meaning “throw together.” Exactly. It was alien to his understanding, this throwing together, a thing emotional and even unreal, and yet vitally important.

The afternoon of the battle for Sheffield, he called Ann on the wrist and got her briefly, and tried to talk to her, and failed. So he drove to the edge of the city’s wreckage, not knowing what else to do, looking for her. It was very disturbing to see how much damage a few hours’ fighting could do. Many years of work lay in smoking shambles, the smoke not fire ash particulates for the most part but merely disturbed fines, old volcanic ash blown up and then torn east on the jet stream. The cable stuck out of the ruins like a black line of carbon nanotube fibers.

There was no sign of any further Red resistance. Thus no way of locating Ann. She was not answering her phone. So Sax returned to the warehouse complex in east Pavonis, feeling balked. He went back inside.

And then there she was, in the vast warehouse walking through the others toward him as if about to plunge a knife in his heart. He sank in his seat unhappily, remembering an overlong sequence of unpleasant interviews between them. Most recently they had argued on the train ride out of Libya Station. He recalled her saying something about removing the soletta and the annular mirror; which would be a very powerful symbolic statement indeed. And he had never been comfortable with such a major element of the terraforming’s heat input being so fragile.
