L'âme de la magie (Les Triades t. 3)

The way soul magic is woven into the characters' lives felt fresh, but I was curious if the author had a specific inspiration for it. Did the magic evolve during writing?

I loved the chemistry but also appreciated the moments of vulnerability. Was there a particular scene that was especially meaningful to write?

Every detail about the magic and society felt so intentional. I'm curious whether the author planned the lore in advance or let it develop organically.
