Interesting, could you possibly translate those texts you posted? Just wondering, thank you for posting this.
Top one is
Ayla/Ara/Eila Mils/Mills Fleuret, the first generation of Oracle chosen to bridge the Gods and mankind.
Ardyn's fiancée,
Bottom is
Ayla/Ara/Eila Mils/Mills Fleuret
The first generation Oracle, and Ardyn's lover.
Approximately 2000 years ago, she was selected and endowed with both the power of the Star, and Trident by Bahamut.
She generously healed and imparted wisdom to people. She was eventually called the "Oracle" who connects God and mankind.
She is an ancestor to the Fleuret family who govern Tenebrae, thus there is a connection to Lunafreya and Ravus.
I used ayla because I agree with the reddit mod, they already had a character in dragon quest with the same first name and they called her ayla. IDK about the middle name, I think Bazztek is probably right. I spoke with the reddit mod earlier about the name, they haven't seen any photos from the event showing her name written down so nobody knows what it is exactly.
Sylva's said it's not written in other languages yet.
