I am interested, though this might be better suited to the Nation section.  Nevertheless, I want in.

I'm pondering a species with caste/hierarchy-based polymorphism.  Like, the grunt-laborers are biologically different from the merchants, are different from the governors, are different from the priest-figures, all tied together with either a Zerg-esque biomass absorbtion, or social mobility actually causing physiological changes in individuals.  It needs work, but I like it.

I think Casual is more appropriate since the Nations section tends to contain incredibly long, detailed posts of several paragraphs and also doesn't generally involve character interactions.

Your idea seems interesting for sure.
