There are aldgoats in game that can be found around Camp Drybone, though it's suggested in a FATE that they come from the south. I don't recall them being anywhere else, but that doesn't mean they can't be found in other zones. Just something to keep in mind when deciding where the tribe was/is located.
Another thing you might want to flesh out a bit is how the tribal society worked. No need to be extremely specific, but things like how leadership was formed, usual diet, religious rituals, if they were nomadic. You know, things that can come out in conversation with your character some day and that could give you insight as to how she was raised.
As for information on aether, I can provide you this wiki link and this other one. The last post there is actually quite nice.
