The First Shaping of the Land

Shortly after the world was created, there was land and nothing else, and flat land to boot. There was nothing of interest. Animals roamed without purpose.
By miraculous chance, First Horse and First Bee. Bored, they exchanged a few boasts.
"Behold how I fly," First Bee proclaimed. "What do your legs do?"
First Horse snorted and kicked the ground, crumpling it up into valleys and hills. "So much for not having strong legs. What can you do?" He showed his contempt further by spitting. The salive dribbled into the valleys and started up the rivers.
"Lord! Master! Great one! I admire what you did. I'll make a new home for you to rest half the day after you perform your feats." First Bee flew up and made the first beehive for First Horse. We call it the sun.
That was how the work of creation began. As for everything else, the oceans, the mountains, the lakes, plateaus, forests, clouds, corn, all else there is, First Pig was busy inventing it at the same time but he never got much honor for it. Things usually go similarly today.

Observed Creation Dynamics

A certain philosopher, curious as to whether snow is a special case of rain or rain a special case of snow, decided on this experiment, that he would create a new world and wait to see which weather phenomenon would occur first, reasoning that inherent decay causes later instances to sway from the original at an increasing frequency. After creating that world, he built on it a cabin with an accessible roof where he waited.
Long before his commendable patience met a test, two figures descended from the sky. One was a man, or one might say the man, for he was huge and perfect in all his parts so that the philosopher operating by established ideas concluded him to be the original. The other was a monster similarly perfect, but in horror, so that he wondered whether its eight wings and twelve horns and its twin stinging tails were of skin, scale, or the force which corrodes.
The two fell instantly to battle. Resting his judgment on similitude, the philosopher cheered for the original man, who after mighty blows did conquer his foe. The fiend screamed with such vigor that doubtless evil would never thereafter be expunged from the world and melted into a column which stretched above the sky for a few seconds before dissipating. The perfect man planted his sword then and spoke.
"I have won another planet for humans who will people it so soon as the rain or snow or ice or water come, which are all arrangements of other things I see no reason to describe or name." He too became first a column and then nothing.
The philosopher returned to record the experiment's outcome. When he published the account, he was greatly puzzled at the widespread interest in what he considered to be the less important aspects.

The Three Ages of Man

"I will make men of gold," the first god declared, "beautiful and immune to corruption."
"I will make men of iron," the second god declared, "strong and hard, impervious to the attacks of beasts."
"I will make men of a bunch of stuff I grabbed," the third god declared.
"What's the advantage of that?" the others asked.
"I've got a hundred out already while you two are working on your first. Watch out there, pal! Can't have the eyes be different sizes! My people have already overrun the world, but keep working on it."
Therefore we await the advent of the men of gold and the men of iron, because they will probably be helpful to us, the rulers of everything beneath heaven, when finally they come.

Pioneer Concerns

Another historic day! Every day seemed historic, or rather, was historic. How could it not be in New Jericho, humanity's first city on another planet? The governor did a few stretches. He needed to be historically serious to deal with the momentous, era-defining task he had the unique opportunity to complete.
On his desk waited the first, no, the inaugural New Jericho survey. The colonists, chosen from a vast population by not only the examination board set up at the sponsors' request but also by their own daring personalities, had all been consulted as to the state of the city in every important facet. Beyond that, they were encouraged to write in the empty portion any items they believed to be essential for the city's prosperity that had been neglected to that point.
Governor Erle Drake sat himself down and read through the surveys, ebullient at first, then disconcerted, and at last positively discombobulated. "But . . . but . . ." His composure abandoned him just as he had left Earth. Dashing to the balcony, he yelled, "Who is it? Who thinks the most pressing business is . . . is . . . remaking astrological charts?"
"Me," a structural engineer passing below said.
"Same," concurred a nearby psychiatrist. "The stars are all different here, so, you know."
"I suppose!" Governor Drake clenched the railing and tried to expel the scorn from his words. "I suppose that next you would like us to establish a commission, for the purpose, of inventing, a creation myth for this planet! And its people!" The scorn was still there. "Oh, can we do that?" A crowd gathered below the capitol building.
"That sounds great!"
"I hope we get something more inspiring than a celestial egg."
"Can it have dragons in it?"
"Better be some incest. Not a proper creation myth without it."
"How about this for a start: once upon a time, matter was energy, and energy matter."
And so a commission was formed, and the governor lost a spoonful of enthusiasm. The next historic event corrected that deficiency, however. There was no shortage of those.

Fantasy Map Tip

Before you start sketching out the plates and wind patterns of your world, ask yourself this: "Does this world even have this junk?" Advice about fantasy maps always starts with denying the fantasy part, which is sometimes desirable but not always.
