Have some plate tectonics and some initial ideas I found jotted down about the Avinar (eventually Abinar) setting while I proof read the next entry.
Humans worship the True Form of man.
Church of the True Form
Teaches that your descendants progress towards or away from Alpha according to their "karma".
Near Alpha language in services.
Two factions - True Form must not be views (iconoclasts) and True Form must be sought out.
Alphas do not grow in number - limited to only so much "spirit stuff". Births only occur after a death.
Alphas divest energy to create servant races.
