Dark Soul: Un Harem Inversé Paranormal Sombre (Héritage Éternel t. 1)

I'm curious about how the setting was conceived—did the author imagine this universe first or build it around the characters' relationships?

The character's moral ambiguity made me question what I would do in their place. How did the author navigate making them sympathetic yet flawed?

The emotional depth added layers to the story, but I wonder if that was a conscious choice to contrast the darkness with hope or tenderness.
