Theory about Sophia in Eorzea

[Frederick22]

Yes, which suggests the symbol of Azeyma is Meracydian in origin (or at least the symbol we have come to know as that of Azeyma) as these are the oldest known ruins with these symbols on them.

My theory is that the Ruins of Qarn, or rather the ruins that Qarn was built on, was originally used by Goddess worshippers who had travelled from Meracydia. I don't know if you were trying to make a point, that was just kind of a statement.

There is an old thread were we had an answer from koji about this.
It was explained the relation between sephirot and its worshipers, and that simbol on the cathedral. It had to do with the sun.
