The world, Crux, was not created, or at least, none of the creation myths have been correct so far.
The old gods were beings of the most basic ideals. The crusading Good, reckless Chaos, malevolent Evil, and rigid Order. They had no real sentience, they were bound to their ways, and their only agenda was to find More to apply their paradigm to. Entire planes and worlds fell to their ways.
When the old gods found Crux, the only inhabitants were the primordials. The world was full of life, unlike many realms the old gods had claimed, filling them with their own versions of sentience. The ancient forests had spirits, the mountains bones, and the sky had a song. The primordials were the life of all the natural things, they were powerful, and they were nearly uncountable. The contact between these elemental forces, the old gods and the primordials, was not a peaceful one.
At first the forces battled openly, the old gods thinking their ideals would quickly win these forces over, as they had done before. They found the resistance strong, and so, called in the creatures that had been made from their divine ideals. Fiends, angels, aberrations, and inevitables all spilled into the world of Crux to battle the Primordials.
The primordials began to die, parts of the world dying with them, turning into lifeless wastelands. And so the great spirits of the world had to form their own creations to counter those of the old gods. The most powerful primordials created dragons, fey, elementals, and other powerful beings. From the lesser came the saurians, elves, dwarves, pech, and folk races, as well as monstrous ones. They began as tools, mindless shells that only channeled the rage of Crux, and fought back the creatures of the old gods. They fought to a stand still.
After an untold time of fighting, the powers had a second contact. The old gods found that force only bred resistance in this strange, living world. The primordials fought a losing battle, and became open to compromise. There was no time of negotiation, no words. Just an agreement that the world and it’s new creatures would be infused with the ideals of all the old gods, not just one in particular, and they would be given the choice between them. The primordials lost the essential connection with their creations, they could no longer identify with them for the vital spirits knew nothing of law or chaos, good or evil. The primordials no longer ran wild over the face of Crux, instead they let their bodies effect the weather and the land in passive ways, turning inwards, their great bodies turning into planes themselves, planes of fire or ice, wind or darkness.
And so did the creations of Crux gain a will. With the touch of the primordials still upon the world, the new ideas and sentience gave rise to a new set of gods, born from the beliefs and convictions of those ancient peoples. The new gods were unlike the old ones. They were born from so many conflicting ideas that, even though each one reigned over a certain sphere of influence, they still had a will, an intelligence. It were these gods that caused the great seperation. Races were divided and spread across the world. In some cases, the seperation was much more pronounced. Elves that deviated far from their roots, from the ideals of the primordials that created them, were turned into orcs, becoming short lived, but full of a rage and passion that burned bright during their violent lives. It was a rather plain and simple race that adapted best, for that was their hidden talent.
Men spread across the world, banding together into tribes and kingdoms, conquering the land and one another until they had subdued other, more powerful races by sheer numbers and ingenuity. The earliest weapons of Mankind was Progenitor. In those early days magic flourished among the races, but men were the first to bind it to machines they had built during the Primordial and Old god war. Progenitor was a shard of a primordial bound to a great war machine. While elves and dwarves, and several other races, soon excelled at awakening magic in weapons and items, as well as binding charms to it, Men were the only ones to use magic itself as a weapon. Not only did progenitor power cannons capable of firing great lances of magical energy, it also gave birth to the first constructs. Golems, the Unborn. Of all the strange creatures and powerful entities that roamed the world in those early days, Man was the most feared. And so it was that other races banded together to battle Men. The battle was greivous and long in the fighting, but at last the other races destroyed the warmachines and sealed Progenitor away.
