It is surely possible to be born on a red planet. The Infanza of Hap lived all her life in the ruby jungles of her homeworld. She was the greatest actress of her age; her tails could convey the colors of a hundred complex emotions in a shimmering fall of shades. So deft were her illusions that the wicked old Rey thought her loyal and gentle beyond words even as she sunk her bladed fingers into his belly. But we must assume that if you require our guidance, you did not have the luck of a two-tailed Infanza, and were born on some other, meaner world, with black soil, or blue storms, or sweet rain falling like ambition denied.
Should you be so unfortunate as to originate upon a planet without copious travel options, due to economic crisis, ideological roadblocks, or simply occupying a lamentably primitive place on the technological timeline—have no fear. You are not alone in this. We suggest cryonics—the severed head of Plasticene Bligh ruled successfully over the equine haemovores of A-O-M for a century. He gambled, and gambled hard—he had his brain preserved at the age of twenty, hoping against hope that the ice might deliver him into a world more ready for his rarified soul. Should you visit A-O-M, the great wall of statues bearing her face (the sculptors kindly gave her a horse-body) will speak to what may be grasped when the house pays out.
If cryonics is for some reason unpopular on your world, longevity research will be your bosom friend. Invest in it, nurture it: Only you can be the steward of your own immortality. Even on Earth, Sarai Northe, Third Emira of Valles Marineris, managed to outlive her great-grandchildren by funding six separate think tanks and an Australian diamond mine until one underpaid intern presented her upon her birthday with a cascade of injections sparkling like champagne.
But on some worlds, in some terrible, dark hours, there is no road to Mars, no matter how much the traveling soul might desire it. In patchwork shoes, staring up at a starry night and one gleaming red star among the thousands—sometimes want is not enough. Not enough for Maximillian Bauxbaum, a Jewish baker in Provence, who in his most secret evenings wrote poetry describing such strange blood-colored deserts, such dry canals, a sky like green silk. Down to his children, and to theirs and theirs again, he passed a single ruby, the size of an egg, the size of a world. The baker had been given it as a bribe by a Christian lord, to take his leave of a certain maiden whom he loved, with hair the color of oxide-rich dust, and eyes like the space between moons. Never think on her again, never whisper her name to the walls. Though he kept his promise to an old and bitter death, such a treasure can never be spent, for it is as good as admitting your heart can be bought.
Sarai Northe inherited that jewel, and brought it with her to bury beneath the foundations of the Cathedral of Olympus Mons.
In the end, you must choose a universe that contains yourself and Mars, together and perfect. Helix Fo chose a world built by viruses as tame as songbirds. Oorm Nineteen chose a world gone soft and violet with unrhyming songs. Make no mistake: every moment is a choice, a choice between this world and that one, between heavens teeming with life and a lonely machine grinding across red stone, between staying at home with tea and raspberry cookies and ruling Mars with a hand like grace.
Maximillian Bauxbaum chose to keep his promise. Who is to say it is not that promise, instead of microbial soup, which determined that Mars would be teeming with blue inhuman cities, with seventeen native faiths, by the time his child opened her veins to those terrible champagne-elixirs, and turned her eyes to the night?
Step Two: Become an Overlord
Now we come to the central question at the core of planetary domination: just how is it done? The answer is a riddle. Of course, it would be.
You must already be an overlord in order to become one.
Ask yourself: What is an overlord? Is he a villain? Is she a hero? A cowboy, a priestess, an industrialist? Is he cruel, is he kind, does she rule like air, invisible, indispensable? Is she the first human on Mars, walking on a plain so incomprehensible and barren that she feels her heart empty? Does she scratch away the thin red dust and see the black rock beneath? Does he land in his sleek piscine capsule on Uppskil, so crammed with libraries and granaries that he lives each night in an orgy of books and bread? What does she lord over? The land alone, the people, the belligerent patron gods with their null-bronze greaves ablaze?
Is it true, as Oorm Nineteen wrote, that the core of each red world is a gem of blood compressed like carbon, a hideous war-diamond that yearns toward the strength of a king or a queen as a compass yearns toward north? Or is this only a metaphor, a way in which you can anthropomorphize something so vast as a planet, think of it as something capable of loving you back?
