Thanks to the final part of the Ivalice raid, a wealth of lore has been revealed about the Viera. Thing is, this information only appears if you speak to the Wandering Dramaturge after meeting Fran. After that, he does not seem to repeat it. Fortunately, I saved that information and have quite a bit to share.
As expected, our new race is divided into two clans, the fair-skinned Veena Viera and the darker-skinned Rava Viera. Currently, it isn’t known how the two clans differentiate from each other culturally, though both are reclusive wood dwellers regardless. Like their Ivalice counterpart, these Viera live and die in the woods and do not suffer trespassers. It’s a code called the “Green Word”. So, it’s not surprising that to leave the wood is to be branded as an outcast and be forever denied by its people. Apparently, Viera who chose to live outside the woods is a new development. In the past several generations, it was unheard of.
But the most interesting thing revealed is the social differences between genders. Like the Miqo’te Keepers of the Moon, the Viera is a matriarchal society. The females are those who reside in the villages and take care of hearth and family. They also nurture the wood itself, by removing fallen trees, planting seeds and eradicating vermin. It’s estimated that eight in ten of Viera born are women, so they outnumber them by a large margin.
As for the males, their lives are quite lonely. When reaching adulthood, male Viera are to become “Wood-warders”, protectors of the forest. After they become Wood-warders, they would shun contact from anyone for the rest of their lives. Only every three to five summers would they return to their village to sow their seed and take any young boys under their wing. Otherwise, they keep to themselves and are even expected to do everything by themselves, be it gathering food, making medicine, crafting clothes and weapons. They live alone and die alone.
So male Viera are so rare that most never see one. They can’t be found in any village and it’s not known if any male outcasts live in city. They basically don’t exist to normal people (Which is going to make it awkward when the expected horde of them appear in Eorzea in a few months).
While the Viera’s relationship with the outside world is one of indifference, the kingdom of Dalmasca have not ignored them. Several kings have tried to subdue the Viera, but always failed. Now, the kingdom tolerates their independence, if they don’t take up arms against the crown. They’re also very welcoming for any Viera who chose to leave the wood.
And to finish this all off, Viera can live up to two centuries and retain their youthful appearance. But do learn from Vaan’s mistake and never ask them about their age.
So yeah, plenty of material to work with in preparation for Shadowbringers. Personally, I find it funny that as a male Viera, being a hikikomori in Hydaelyn is not just an option, but it’s mandatory.
