Hell yeah, some frenche lore here i love that ( i'm french but the myths in my area are wayyy less cool ngl )
The storytelling in your tracks is absolutely insane, i would definitely love to be playing a game with this music playing. I really enjoy the cover art too !
I think my favourite one is the first one : Ouverture, as it sets the mood perfectly for the 2 others coming and the universe you depicted, really good job !
