Of course, answer only what you want I don't expect you to give me all the answers, after all part of the fun is what actually true and if I am right or not.
This is some of what I observed and are theories of mine. (I have so much more to say)
Got it.
It was clear but I always look for something deeper hidden away in stories again part of the fun is the mystery and solving them.
It is very interesting as I gather, they are both of Latin origin which makes me think there's hidden meaning there Caelum meaning that of heaven but also of a chisel which is extra meaningful as that is a small blade used to carve. Possibly to refer to the fact he is carving out his own destiny? (I will say more in another message below.) Aria's name is one with ties both Latin and Italian meaning air or a melody which I'm not sure what that could mean for her? A siren type of ability in the future? (Again, I will say more in another post.)
I have theories about the cave too and why there are others traveling down it and has to do with the one angel NPC in the corner... If they are really an angel but I think they are just dressing up as one
I have much I want to say including a timeline of events and about the why the citizens act stranger as Aria's lust increases.
As always thanks for letting me talk about all of this.
