I've given you my personal opinions on the plot you wrote so far, but I'd like to read more

The story really caught me from the first read.
If you have written some new part, I'll surely give it a look.
BTW, I saw you updated the tutorial with a really good introduction.
I've actually no ideas about what I can add to that, maybe I'll write something about settings.
Anyway, back to your topic...
The title really intrigued me... what does
Litthenen Y mean? Is it related to something I can't understand ATM?
And what would be
Saire's role in the story?
What kind of world are you referring to? A medieval-punk FF6-like world or anything different?
You didn't descried soldiers' weapons and equipment, but from the info I've gathered, I deduced it would be more like earlier Final Fantasy series's games
Siele is a really good character, from what I got reading your reply. So she has some maternal feelings for Litlaia but she has to hide her in the castle since she's the most important pawn on the events' chessboard...
I wonder how you will develop their relationship.
