What languages do the Ascians speak?

[Kranel_San]

I don't mean the tongue of the Ancients. I mean whatever spooky language they use in ARR and Heavensward. It is very different sounding from the Ancient language, but is clearly meant to be old. Lahabrea refers to our language as crude by comparison.

Probably a leftover from early designs.
Either that, or it's actually the ancient language, which the shades of Amaurot do not imitate it correctly.
It also could be an accent of the ancient language because languages change throughout the years and ascians have been around for 12k years so it's kind of possible they adapted new terms and some words from newer languages until they got a distinct accent that doesn't sound like what the Amaruotian shades say but are considered the same language.
