That would be one in million like Korra because most of the Avatars mainly born in the place
that fill with richful things and having a great the civilized places. So it would be one heck cool
and amazing if an Avatar will be born from one of these clans or tribes.
I think there is always a small but notable rise in population whenever an Avatar dies or is killed so the parents can brag to their neighbors "Haha our kid's the Avatar!"
I mean everyone will be having babies in an attempt to concieve the next Avatar, leading to a small but notable rise in population (at least for the next nation or element in the Avatar cycle).
How would they know when the Avatar is going to die?
Not only that, there's 9-10 months before the baby is born.
Like what I said, one in the million.
Me too! I love how they're so different from all other nations and that they're very spiritual.
