The Prologue for the book gives some background into the mythology of the setting and reads thusly (remember this is the rough first draft). There is literally thousands of more words of the background that I have already written in prep for NaNoWriMo.
Prologue
Millions of Human Years Ago
In the beginning, there were the two universes, Ley and the Other, or at least, that’s what the inhabitants of the Ley called it, for there were no inhabitants of the Other. The two universes existed apart from one another, intersecting at a single point in timespace. A point so small that nothing ever crossed between the two. In fact, it was so small that even Order, who had originally created the Other as for entertainment, and his mischievous twin sister, Chaos, bothered to notice its existence. That is, until a planet formed and went careening straight through that point, over and over again. With every pass, for millions of years, the Earth was awash for a single moment in the power of Ley. Over those millenia, the Earth became entwined with Ley and was caught in a sort of net of Ley-powered lines that circled the eventually blue-green globe. The power of Ley, what the Humans of Earth now call magic, began to have a fascinating effect upon the tiny little planet. Life began to exist and a myriad of plants and animals came to exist there. The Earth itself was only just becoming aware of itself when it also came into the awareness of the inhabitants of Ley, Two of them in particular.
A pair of kind, patient, diligent scientists humbly stumbled upon its existence one day when they were doing experiments attempting to determine why there seemed to be far less mattergy in Ley than that which was recorded millenia ago. Time there ran differently than it did in the Other and they soon found the cause of the problem, something no other Leyllian had done before, in fact, no other Leyllian was actually interested in the phenomena whatsoever. So it’s no surprise that these two were the first to discover the rift in the Ley and the fact that there was what appeared to be an entire Other universe on the far side of that rift. So they named it the Other and began further investigation.
Eventually, they reached a point in their research where they could simply go no further. They had done all the remote investigation that they could do through the means available to them, which was quite cast indeed as all Leyllians are made of the mattergy that the Ley is made of and can tap into it whensoever they choose. Since they were in agreement that nothing further could be learned about the Other from within the Ley, they decided that the only thing left to do, was to travel into the Other and continue their research. Not being ones to break, or even bend the rules, they did all the necessary steps to get the proper clearance from the Elder Ley but none of them really seemed at all interested in what it was they wanted to do. So, the two took it upon themselves to determine the best course of action, which they agreed was to simply, go to the Other and continue their research, and so they did.
