Keep in mind every shard is locked away from the real universe by a space-time dimensional barrier that only allows aether, and perhaps Dynamis, to pass through it.

I'm sure the amount of aether is related to all things lively and vital on Etheirys. The story says as much, and it also says everyone used to have aether like that and live a long long time.

I had to go back and look at the scene to see it. Y'shtola says, "it may predate the empire." because it's, "Unlike anything she's ever seen." Emet-selch merely says that anyone pre-Sundering would remember it. I said it was the Ronkans, due to the later questline where we see the Meteorshower Mural with the Vieran Sorceress.
