Ugh. You made my head explode with a million ideas. You will be the death of me, Mr. Moose!
Okay! So, I was typing a response to the quoted text, and then so much else happened, and I am trying to bake cupcakes at the same time. Cut and paste of what I was typing:
Mr. Moose, I do not want to interpret what you are saying incorrectly, but the beings from the Void seem to have their own aether when they die, which is foreign to our world and rejected by our Lifesteam. So, they are unlike the rest of Hydaelyn's native creatures whom return to the Lifestream upon death.
Then, this thought happened: (Oh this made me think about Teleport and Return spells - how exactly can Ascians use teleport magics if they can't return to our Lifestream if they are not from our world?)
Then, I was thinking this: If I were to borrow your loremonger cap, I do not feel that [the Void is] just "beyond" the aether, but rather from a "different" source of aether or Lifestream (I was going to call it a Deathstream seeing as it kind of feels like an "opposite" to our Hydaelyn, but that wouldn't make sense - and I certainly wouldn't want to swim in it with that name). The world of Zodiark? Who knows. I am not sure how this plot will pan out, I imagine many different scenarios from what little we have been given.
This actually happened first, but I put it at the bottom, and my cupcakes are burning!: I am imagining the Void may be a little different to past Final Fantasy titles in a way. Perhaps it is more like the torn world from Final Fantasy Dimensions when the Crystal shatters... In our game of XIV, perhaps Hydaelyn is the light half, and Zodiark the dark half, yet they were actually once one whole crystal and one whole, complete, world. This could explain where there are creatures familiar to both realms, like our beloved Gnats or Hippogryphs. These worlds aren't exactly opposites, yes feel in opposition because of the split. Neither is complete without the other, and thus why we are in a chaotic state of Umbral and Astral as they are fighting to remerge/separate themselves. This idea of a "torn world" might lay credence to what the Ascians have said to us through the plot, of fighting for the same cause.
In Dimensions, you play as both the Warriors of Light and Darkness. Both parties reunite, with the goal of reestablishing the world, and thus, the Crystal. I know this is a different game, but could you imagine if Ascians became a playable race in the expansion, and turn out to be our ally rather than foe? Hmm!
I do feel we are being set up with many plots - one similar to many past titles with the idea of politics and religion and being champions of your own fate, but also (as you have hinted in previous posts) the idea of Warriors of Light and Darkness.
The Void and the Lifestream are two things I am interested in, but careful to think about, for fear of my small Miqo'te mind. It results in burnt chocolate cupcakes.
This has nothing to do with bestiary, so I apologise.
