In ARR they played a fairly important role in our ability to pierce Garduda's storm.

I do not think they have been brought up much since then, but could be wrong and I am open to seeing examples.

Is 'corrupted' an aetheric type?

"Aether can be aspected into six elements—ice, water, wind, lightning, fire, and earth—and drawn towards two polarities: Astral, the active, and Umbral, the passive. It also comes in three forms: memories and souls which are interconnected, corporeal aether like the aetheryte, and forms of nourishment that are in constant flux."-from the wiki

Is corrupted aether a corrupted version of each type? Like corrupted lighting, corrupted wind, etc. Or would it be considered a 7th aspect? In which case could their be astral and umbral variation of corrupted aether?

And further, would a primal fed from corrupted aether crystals exhibit unique qualities as a result?

Just general musings on a previously introduced concept that has not seen much use in current lore.
