In the beginning...

the way this is going to go down is thus:
Character A is either supposedly the first person to travel faster then light away form Earth, or is in fact just the first person to do that and end up in a particular system. He quickly discovers that he is not alone in this system. There is a fully human colony settlement on one of the planets. This is teh culture of the Idealists. A basic principal about philosophy is that once you can prove your theory, it ceases being philosophy and becomes science. The Idealists have proved Idealism to be true. The physical universe, in fact, does not exist. And yet, these people have not chosen to transcend beyond it. As yet, I don't know why. So, in typical Space Opera format, something breaks on Character A's spaceship, and he cannot go home. The Idealists take him into their society, but it does not take Character A long to realise that there is something not quite right in what appears on the surface to be a Utopia.
Enter Character B. She is an Idealist who has lost her faith in the proof of idealism, and thus lost her idealist powers (this wil be explained in the body text of the novel). She accidently triggers a counter-movement against the Idealists by the fallen Idealists... let's call them Realists.
In true Space Opera form, Character A and Character B cross paths and things start to happen, and they are drawn into a plot thousands of years old that involves God Himself.
Battles will be fought, the universe will be torn asunder, and in the end, what will remain? we'll see, fifty-thousand words down the line.
