I want the ROs to be a combination of playersexual (like Breden, and to a degree Suzane/Kala) and set gender/preference. Calea’s attraction to helots is one of the most interesting things about her, and I also decided she’d be straight rather than bi like her brother. Other set-preference romances rolled out from next game (e.g. Elery, Cerlota Viore, Aireq of Halassur) will fit on various points of the LGBT spectrum. Ultimately everyone should have some choices, though because this isn’t a dating game i can’t guarantee that everyone will have a character they like.
The Tragic Romance of Hector Keriatou is only available to aristos, but I’d be careful assuming he’s an RO in any consummatory sense of the word.
