How get someone pregnant?
Since there's only one not entirely helpful answer: pregnancy is currently only supported for 3 characters out of which you can only impregnate two (gotta choose between Heloise and Valzira) which can be impregnated by having vaginal sex with them and not killing them after (valzira needs vagina sex, Heloise needs sex at least twice, the third is Enis who you can meet in the opening while escaping the guards - climb into window -> take gently -> spare life)
