[Abstract Nova]

Simple Man,

For good or ill, the little secrets are never explained. In a broad sense, they are byproducts of the unhinging of reality in the Potter's Lake area, something covered in the corebook. No other supplements will EVER be needed to play the game. All future supplements will ever do is expand the setting or add more background information; they will never invalidate the corebook material or be necessary to running the game. For example: the first supplement, Paradise Lost, introduces more townsfolk, more rumors, covers the history of the area in greater detail, etc.

GMs are free to explain away the little mysteries as they see fit or not explain them at all. Taking a cue from David Lynch, it's the mysteries themselves that are important, not their explanations.

Thanks for the interest, and sorry if the approach doesn't quite work for you.
