Does anyone know how many of these ladies there are? I only got 3 in hard mode but in an easy game they gave me another one, does anyone know how to get them all?
They are given as rewards for reaching certain levels of favorability with your colleagues. Usually at 50%, or 33% and 66%. Just max out their favorability, and you'll get them all.
There are human, dwarf, elf, sheep and hare (small furry), cat and wolf (furry) and dragonkin. One for every race.
Sheep is particularly good if you want to automate production, as her descendants pretty much never run out of birth limits. Dwarf is similar, but less powerful.
Dragonkin is good for breeding superior monsters.
Rest of them aren't particularly useful long-term.
Edit: I think hare and wolf are from Sena and Lena (the brothel keepers), dragon is from the lab, elf is from the dismantling, human and dwarf are from the merchant. Not sure where the sheep and the cat are from. I guess at least one of them is from the blacksmith.
