How is the Allagan equipment explained in canon?

[Empressia]

Lorewise, ancient civilizations in FF14 like Nym, Amdapor, Gelmorra, etc are inhabited by the SAME RACES we see today, chances are the Allagan E-M-P-I-R-E (empire means ur unifying or conquering a whole tons of other races living in subjugated territories besides ur main race) is composed of the 5 playable races or more. As for the magically suit the wearer or user instantly, logic wise, its hard to believe that a high tech civilization which created data plates or discs as indicated by the shape of those allagan tomestones, isn't capable of storing massive amount of same or specific type of gears in a single compressed chest (which shape is a high tech creation), however due to time and age, our toons might only found just ONE piece of the gear that is salvageable or is in good shape)

In short, when Allag fell, the only races present would have been Roe, Lala, and Elezen. The Mi'quote and Hyur are much more recent additions to the cast, so to speak.

That's the thing, though. I mention it in my OP, but both the Hyur and Miqo'te didn't migrate to Eorzea until thousands of years after the fall of the Allagan Empire. It just doesn't make sense for there to be equipment tailored to fit the Miqo'te specifically. Given that we known Darnus is of an Allagan bloodline, I feel as though the Allagans may have been a precursor to modern day Elezen. Suffice it to say, while Roegadyn and Lalafell technically could have been a part of the empire, I don't think there would be any Miqo'te that lived in the empire unless there were some groups that migrated prior to the ice age.
