I think the t4 named Set priest that should have the chance to be either Male or Female should be Amn’Ut the Blessed and not Hoshun the Fang. In the description for Hoshun’s daggers it says Hoshun is a male. I don’t currently have the daggers so I can’t quote the exact wording used. This is just a minor issue but it would make more sense.
You are right about this male part:
… to growing up to become a family man, only to lose his children to the Reaping Storm…
I think that it could be a bug as he is suppose to be a male and his info states it I would report it as a bug if I were you. I have never seen him as a female yet.
