RE: Hamsa mount itself was what I was surprised we didn’t get.

The archaic font could easily be a rediscovery or preservation of features because of typeface, or a funkiness related to Tural’s need for a universal script. In fact, rediscovery or a scholarly effort to work back to a root form out of fantasy justification to have a version of Eorzean applicable to a wider language/culture base could make sense. Church Latin and all that. The reason could be very convoluted or simple.
