There is probably a in-world reason for nona speaking all the languages perfectly, ¿where did that come from?

And given that “tongues” is one of the gifts of the holy spirit gives in the bible…
That has got to be intentional, right?

On the other hand it could have to do with the steles “covered in dead languages”

This is brand new to the magic we have seen this far, again, where did that come from?
