I've been working on a fantasy concept with some gender-neutral tones in parts, myself. I've got a race called tumans who are androgynous and don't have traditional binary sexes. But they are the most romantic and monogamous race, and might be considered the most western or most human-like in their traditions and culture, while the other two major races (bumans and lumans), have basic male/female sexes, but they're a lot more polyamorous.
But I've also just been thinking recently about how I'd tackle the tuman language, and of course all pronouns would have to be gender-neutral. But with the other two races, I've even been questioning the structure of their languages, as well. Would they have to have gendered pronouns? I'm not sure it's even necessary for them, so I might semi-enforce a gender-neutral language to all three races, and see if it works out.
