And that was it. On Mars there would be no equivalent of the South Pacific or the South Atlantic, or the Indian Ocean, or the Antarctic Ocean. In its south there was only desert, except for the Hellas Sea, a circular body of water about the size of the Caribbean. So while ocean covered seventy percent of the Earth, it covered about twenty-five percent of Mars.

In the year 2130, most of Oceanus Borealis was covered by ice. There were large pods of liquid water under the surface, however, and in the summer, melt lakes scattered on top of the surface; there were also many polynyaps, leads and cracks. Because most of the water had been pumped or otherwise driven out of the permafrost, it had deep groundwater’s purity, meaning it was nearly distilled: the Borealis was a freshwater ocean. It was expected to become salty fairly soon, however, as rivers ran through the very salty regolith and carried their loads into the sea, then evaporated, precipitated, and repeated the process — moving salts from the regolith into the water until a balance was reached — a process which had the oceanographers transfixed with interest, for the saltiness of Earth’s oceans, stable for many millions of years, was not well understood.

The coastlines were wild. The polar island, formally nameless, was called variously the polar peninsula, or the polar island, or the Seahorse, for its shape on maps. In actuality its coastline was still overrun in many places by the ice of the old polar cap, and everywhere it was blanketed by snow, blown into patterns of giant sastrugi. This corrugated white surface extended out over the sea for many kilometers, until underwater currents fractured it and one came on a “coastline” of leads and pressure ridges and the chaotic edges of big tabular bergs, as well as larger and larger stretches of open water. Several large volcanic or meteoric islands rose up out of the shatter of this ice coast, including a few pedestal craters, sticking up out of the whiteness like great black tabular bergs.

The southern shores of the Borealis were much more exposed and various. Where the ice lapped against the foot of the Great Escarpment there were several mensae and colles regions that had become offshore archipelagoes, and these, as well as the mainland coastline proper, sported many beetling sea cliffs, bluffs, crater bays, fossa fjords, and long stretches of low smooth strand. The water in the two big southern gulfs was extensively melted below the surface, and, in the summers, on the surface as well. Chryse Gulf had perhaps the most dramatic coastline of all: eight big outbreak channels dropping into Chryse had partly filled with ice, and as it melted they were becoming steep-sided fjords. At the southern end of the gulf four of these fjords braided, weaving together several big cliff-walled islands to make the most spectacular seascapes of all.

Over all this water great flocks of birds flew daily. Clouds bloomed in the air and rushed off on the wind, dappling the white and red with their shadows. Icebergs floated across the melted seas, and crashed against the shore. Storms dropped off the Great Escarpment with terrifying force, dashing hail and lightning onto the rock. There were now approximately forty thousand kilometers of coastline on Mars. And in the rapid freeze and thaw of the days and the seasons, under the brush of the constant wind every part of it was coming alive.

When the congress endedNadia made plans to get off Pavonis Mons immediately. She was sick of the bickering in the warehouse, of arguments, of politics; sick of violence and the threat of violence; sick of revolution, sabotage, the constitution, the elevator, Earth, and the threat of war. Earth and death, that was Pavonis Mons — Peacock Mountain, with all the peacocks preening and strutting and crying Me Me Me. It was the last place on Mars Nadia wanted to be.

She wanted to get off the mountain and breathe the open air. She wanted to work on tangible things; she wanted to build, with her nine fingers and her back and her mind, build anything and everything, not just structures, although those would be wonderful of course, but also things like air or dirt, parts of a construction project new to her, which was simply terraforming itself. Ever since her first walk in the open air down at DuMartheray Crater, free of everything but a little CO₂ filter mask, Sax’s obsession had finally made sense to her. She was ready to join him and the rest of them in that project, and more than ever now, as the removal of the orbiting mirrors had kicked off a long winter and threatened a full ice age. Build air, build dirt, move water, introduce plants and animals: all that kind of work sounded fascinating to her now. And of course the more conventional construction projects beckoned as well.

When the new North Sea melted and its shoreline stabilized, there would be harbor towns to be inlaid everywhere, scores of them no doubt, each with jetties and seafronts, channels, wharves and docks, and the towns behind them rising into the hills. At the higher altitudes there would be more tent towns to be erected, and covered canyons. There was even talk of covering some of the big calderas, and of running cable cars between the three prince volcanoes, or bridging the narrows south of Elysium; there was talk of inhabiting the polar island continent; there were new concepts in biohousing, plans to grow homes and buildings directly out of engineered trees, as Hiroko has used bamboo, but on a bigger scale. Yes, a builder ready to learn some of the latest techniques had a thousand years of lovely projects ahead of her. It was a dream come true.

Then a small group came to her and said they were exploring possibilities for the first executive council of the new global government.

Nadia stared at them. She could see their import like a big slow-moving trap, and she tried her best to run out of it before it snapped shut. “There are lots of possibilities,” she said. “About ten times more good people than council positions.”

Yes, they said, looking thoughtful. But we were wondering if you had ever thought about it.

“No,” she said.

Art was grinning, and seeing that she began to get worried. “I plan to build things,” she said firmly.

“You could do that too,” Art said. “The council is a part-time job.”

“The hell it is.”

“No, really.”

It was true that the concept of citizen government was written everywhere into the new constitution, from the global legislature to the courts to the tents. People would presumably do a good deal of this work part-time. Nadia was quite sure, however, that the executive council was not going to be in that category. “Don’t executive council members have to be elected out of the legislature?” she asked.

Elected by the legislature, they told her happily. Usually fellow legislators would be elected, but not necessarily.

“Well there’s a mistake in the constitution for you!” Nadia said. “Good thing that you caught it so soon. Restrict it to elected legislators and you’ll cut your pool way down — ” Way down —

“And still have lots of good people,” she backpedaled.

But they were persistent. They kept coming back, in different combinations, and Nadia kept running toward that narrowing gap between the teeth of the trap. In the end they begged. A whole little delegation of them. This was the crucial time for the new government, they needed an executive council trusted by all, it would be the one to get things started, etc. etc. The senate had been elected, the duma had been drafted. Now the two houses were electing the seven executive council members. People mentioned as candidates included Mikhail, Zeyk, Peter, Marina, Etsu, Na-nao, Ariadne, Marion, Irishka, Antar, Rashid, Jackie, Charlotte, the four ambassadors to Earth, and several others Nadia had first met in the warehouse. “Lots of good people,” Nadia reminded them. This was the polycephalous revolution.
