@Madrugada: yeah, that's increasingly what I'm thinking. Trying to squeeze them all into one work (of however many volumes) seems to get too choppy, too confused, and I'm always feeling like I'm not giving any of them enough time, enough story, enough continuous attention.
Another part of the frustration is that, while there's definitely overall conflict, and clashing ideologies, in this world — it's not the kind of thing that really lends itself to the gigantic, world-changing climax. It's more likely that the conflict will lessen, that one side will perhaps slowly win or both of them merge into each other, or that new divisions will slowly grow to overshadow this one.
I've been trying to force myself to devise a conclusion of that kind of epic scale, and the thing is — it's not there. The very design of the world forbids it, really. As does my innate sense of how I believe the real world works, which translates over here — while many things differ between our world and theirs, this is not a place of narrative causality; people do not differ all that much there and here, in fundamental motivation and behavior.
In a sense, it's as bad as trying to force a change on a character that's against their nature — it doesn't work right.
So, yes, smaller works, multiple viewpoints, and an acceptance that epic scope is not required. It'll be there, in the background, but no world-changing dramatics.
A brighter future for a darker age.
