Yoshi P did confirm in an interview during fan fest they have written new lore to incorporate the male viera into the world and it wouldn't be they just "suddenly reproduced and appeared in big numbers."
What are your thoughts? We know the males live separately from the females and remain elusive within the Greatwood. However, I am assuming with Eorzea on the verge of a new calamity and the mass-destruction, it would naturally force them out of the woods to join the fray?
It seems the females are the dominate in the Viera race, and the male designs do seem more delicate. I have to wonder while they are warriors, if they tend to more of the domestic needs of the tribe, such as gathering, hunting and other types of work.
(My more funny theory is the male viera are so much prettier than the females, out of jealousy they force them to live in isolation).
