Freya, herself only knew about this little bit of information, about the title of her races progenitor and primordial because of her higher tiered bloodline while somehow Luna and Wix didn't despite there bloodline being of the same tier. And the reason for that was simple too — there races themselves.
Nevertheless Freya's sovereign tier bloodline still wasn't at the tier where she would actually understand as for, just what was a primordial sin or what it ment to be a demon from the line of a primordial sin let alone the original sin, meaning that she only felt deep sensation of reverence and fear regarding this strange concept of primordial and progenitor of her race and nothing else.
Therefore if there ever come a time where she had to abandon her bloodline as a lust demon for something better she would certainly do it without a doubt.
