So, how old is Hildibrand's mother?

I mean, she doesn't look to be even over 20


Now, what happened? Does the Manderville Clan found the fountain of youth, and their fortune comes from selling immortaily to the rich people of Eorzea? But Godbert looks pretty old, that is certainly not the case. Oh wow, Godbert's such a kink, that old man marrying a young, pretty blonde. Those cradles certainly do a lot of rocking.

Now... what really transformed my head into a ticking time bomb is... She's the MOTHER of a FULL GROWN ADULT.

HOW OLD WAS JULYAN MANDERVILLE WHEN SHE WAS PREGNANT WITH HILDY????
I really don't want to know the answer to this.
Or maybe I can...
