I have questions about the Allagans I can't really find online through searching and don't recall finding answers for in-game.

We know that the Allagans were a spacefaring society, but this doesn't tell us much about their actions in space. We only really know about Dalamud and the Monitoring ship that crashed on the moon. There are plenty of clues in Azys Lla regarding their spacefaring abilities, such as Helix being a spaceport of sorts; and various sites such as the Hypersteller Downconverter and the Alpha Comm Beacon that seem to be used for communicating with space; Either with their own ships or for sending out and receiving transmissions elsewhere from space.

Heck even the Big fish in the Hyperstellar Downconverter ( A fish named Ceti ) with the description reading "Modern naturalist circles were positively abuzz following the discovery of an Allagan tomestone which contained an article on an oliphant's trunk with a maw so sensitive, that it was believed the wavekin could detect activity in the very heavens. Further study of the work however led to the conclusion that the piece was satire.", doesn't this vaguely mirror Hermes studies on Celestial Aether?

The Allagans put Dalamud in space around the moon. Did they just not notice Zodiark's prison on the moon? Did they not go "Gee whiz that's a weird tower on the moon..." Like even Golbez was able to just walk to the moon and kill the watcher.

The Allagans were aware of the Omicrons, even if Omega itself couldn't remember where it came from, it was obviously an advanced weapon FROM SPACE, and they even used it against the Meracydians in the second invasion since they knew Omega was designed to fight dragons and they knew dragons were aliens too. So.. Were they aware of other alien civilizations? All life in the universe was extinguished (as far as we know) by modern times; but this was like 6000 years ago; and Meteion did start her song of oblivion like 12k years ago.. sooo...??? Surely there are other aether-rich worlds in space that were able to avoid destruction.

My main questions being... Were the Allagans aware of what was going on in the Universe with Meteion? Did they send out ships into space? Did they know that everything was dead by that point? Did they intercept Meteions message in space? Did the Final Days sadness ray affect ships in space? Why didn't Bahamut inside of Dalamud get Final Days'd? He might be a primal but primals are still living creatures created with creation magic right? Did his unending rage keep him from getting sadness'd?

This is why we need a Meracydia expansion. Think of all the metal sci-fi lore we could be getting!! Also please help me find answers to these questions.
