Karinaverse (Traveller)
Based on the classic sci-fi RPG Traveller (which I don't own) and set in a vast interstellar empire more than 3500 years in our future. Named after Karina Farwall (created by user "amiwakawaiidesu" of DeviantArt and used with permission) who's an all-around skillful Scout pilot and seems to get pregnant a lot. And yet she rarely actually gives birth, thanks to the gene vendor system: more details in the stories.
