Les dieux déchus

The gods in this story are far from perfect, which adds a layer of realism to their mythic struggles. I'm curious what influenced this reinterpretation of divine characters.

The characters' journeys seemed to explore whether fallen gods can find redemption or are doomed to repeat their mistakes. How did others interpret their arcs?

The cultural elements added richness to the story, but I'm wondering whether this combination was planned from the start or evolved during writing.
