(Incidentally, if you were wondering what I was doing this weekend, I was attempting to nail down the characters for my next ongoing longer series. I think I have a good handle on four of them, as of now. The fifth… is troublesome.)
Planet of Hats: Trying very hard to avert this one, except for in-world explicable exceptions like relatively new, low-population colonies, and odd cases like Valiár (Imperial Core), one of the Thirteen Colonies whose colony ship malfunctioned explosively, leading to the planet being populated by large numbers of clones of an original small group of archetypes. (And even then, they’re not all that hatty.) And, of course, some created species.
