Yep! Before I was born, it was because of the place you came from. Like...airbenders were from the Air Nomads. Firebenders from the Fire Nation. Waterbenders from the Water Tribes. Earthbenders from the Earth Kingdom. ...But for a long time people've intermarried ever since the end of the war, so now you can find some of them everywhere I guess!!

Except airbenders. There are only my siblings and my daddy and I, of those. And Korra.

You can probably get to see the other bending here if you want. There's at least one person from each bending style here, and two Avatars.
