Sylvie is 180 days, I think. As for how long Steele's pregnancies last, that totally depends upon Steele's pregnancy speed multiplier, which depends upon what transformatives Steele has taken.Any of you code spelunkers know how long a pregnancy lasts when you are knocked up by Gel Zon, the Uveto Cundarisn Stormlancer? Similarly, how long does a pregnancy lasts when you knock up Sylvie? How about the Gabilani Chemist?
