This is a subject I’ve discussed pretty thoroughly with my writer, and we’ve come to the conclusion that “they” is the pronoun we’re going to be using when referring to anyone from the kukun’lu species.
Race is a big deal on where I live (and most other places in my world too, honestly), and that’s something that changes with time for us. I have to imagine that being permanently plopped into one segment or another of a sub-species would have to be an even bigger deal for you guys than race is for us.
So yeah. Not looking to step on any toes with that one.
