easily. The actinic rays aided mutation, and the virgin surface of the planet permitted adaptive
radiation on a scale never imaginable on Earth.
Asteroids strewed eggs; at first invertebrates, then those of backboned life forms, though none
so advanced that the young required parental care.
The colony ships arrived.
In a degree, the planners who seeded Venus with life had been too successful. Land and sea
both teemed with a savage parody of "Nature red in fang and claw."
The seas proved easier to colonize—"at first," the planners said, though the temporary
expedient quickly hardened to permanence. Domed cities sprang up on continental shelves a few
thousand feet down—beneath the sunlight and the light-driven violence of the surface layers, but
well above the scarcely less fierce competition in the deep trenches where all organic matter at
last settled.
Seven days, four hours, and thirty-four minutes after the last colony ship landed on Venus,
Earth's final war triggered a fusion reaction in her oceans. By astronomical standards, the
resulting star was both small and short-lived; but it would smolder for thousands of years, and its
first milliseconds had been enough to cleanse the planet of life.
Mankind survived in the domes of Venus.
Only in the domes of Venus.
The individual cities were independent and fiercely competitive, though the causes of their
conflicts had no more logic to those not involved than did the causes of men's wars through the
previous ages. Earth's blazing death throes imposed order of a kind on the wars of Venus, but not
even that warning trauma could bring peace.
Nuclear power and weapons were banned, as guns had been banned in Japan during the
Shogunate. The ban was enforced with absolute ruthlessness. Domed cities were vulnerable to
conventional weapons of the simplest sort. A dome which was believed to harbor nuclear
experiments was cracked so that water pressure crushed its inhabitants into the ooze before they
could drown.
Apart from that, war on Venus was fought on the surface, and by warriors.
Independent contractors, like the condottieri of Renaissance Italy, built bases and fleets with
private funding and staffed them with volunteers. They fought one another for hire, and in the
interim they fought the jungles for their very lives.
Domes went to war according to set rules. When battle and mercenaries' blood had decided
the point at issue, the losing city ransomed itself to penury. The winning dome recouped the cost
of the fleet it hired, and the winning military entrepreneurs collected a comfortable victory bonus.
The losing mercenaries had the amount of their original hire and whatever they had managed
to save from the wrack of defeat. That might be enough for them to go on to lesser contracts,
desperately trying to rebuild their fortunes; or they might be forced to merge with another
company on unfavorable terms.
Sometimes they merged with the fleet which had just defeated them. Business was business.
The fleets seemed a romantic alternative to life in the climate-controlled safety of the domed
cities. Civilians aped the dress and manners of the mercenaries or scorned them, but no one in the
domes could ignore fleet personnel in their uniforms and their dark-tanned skins.
There was no shortage of volunteers to take up the reality of the romantic challenge. . . .
