How Would Viera Fit In XIVs lore?

[Nestama]

For Viera to work, they'll need to already exist on Hydaelyn (making them playable because of the Ivalice raid wouldn't work). As we never saw a Viera in Othard, or amongst the Garlean empire/army, I'm doubting we'll be seeing them in Islabard (Garlean controlled territory). This leaves The New World to the west of Eorzea... and since we might not even get into Islabard until either 5.0 or 6.0 (based on what Yoshi-P has implied regarding storming the Garlean capital), we probably won't expect Viera to be playable until 7.0 :T

Reason why they can't be playable after the Ivalice raid is released: lore and timeline. If the Ivalice raid is going to be a portal to the Ivalice, then it's impossible for them to be playable as something shouldn't exist before they can exist (it'd be a paradox and there'd be no explanation behind it). If it's not a portal to the Ivalice, then why haven't we seen them in FFXIV yet? Why aren't they vaguely mentioned or implied in the lore book?

Lupin on the other hand...
