Aether

[dubstephalflife]

And is it possible for Aether to become corrupt? or void aspected?

It is! If I remember correctly, the main questline leading up to fighting Garuda mentions this. Specifically when you go to The Burning Wall, they mention that the crystals there are corrupted aether. I cannot remember if the other locations are corrupted crystals too. The ones at Burning Wall are either from the piece of Dalamud that crashed into it (and collided with the aetherial gate there) or Bahamut spewing aether all over the damn place.

I'd recommend this discussion about the void. I like the theory that the Void is its own form of aether just not of this realm.

And to make longer posts, write it in notepad or something, post the first few lines, then edit to post the rest.
