Yooo I'm getting a creepy vibe rn, Nana sounded a bit out of character...Also, I feel like she's holding somewhat of an act....
Also it's getting a bit Meta, Lilliana seems to know about "fate"
The whole town is just a ruse to make Felicia "experience" the commoner life, every single one of the village people are some kind of kingdom agent or low-ranking noble tasked to make her stay as smooth as possible.
