General conflict is not between life and death. Both persevere. Life is motion, and many things move. Sure, death is longer-lasting (I hope that’s not a surprise to anyone), but life does last and arrise often.
It’s higher things. The push for moving things in a different direction, of imposing one’s will, of wishing for something more—whatever that may be.
It’s things falling apart. It’s struggling however against the way things are.
And the happiest are those on the periphery of the story. The “suppporting caste” are generally as happy as they are oblivious. The more they simply ignore life’s stuggles and think in bland, tried ways about things, the more undisturbed they are.
So, story starts with botanist not being able to give his talk because of his craft needing sterlized.
At that conference is where the Dean makes his move. The botanist (and many others) knew this. Things move quickly from there. Backstory is through flashbacks. The problems people can solve are the simpler, more personal ones. The big ones people miss or die trying to hit.
So, basic story is the Dean breaks away to form his own society. The rest fights him. The Dean is very clever and wins most battles—including the final plan to just step aside and let the Growth chew up the rest. The rest find them, though, and spank the Dean into retreat. The Dean, though, had implemented a plan to exterminate the rest just like they did the aliens. Then they all get eaten.
In the sequel, the botanist learns from the pirate queen that after the beast, the aliens came in and hunted humans into subjugation. Wouldn’t exterminate them, but keep them down to less than a hundred thousand (just like they do the other race that fills the niche of something or other). Humans have become highwaymen. Well, yeah, but they do need to settle into a niche that’s still win-win.
So, things to sort
