Die Sieben Kristallkugeln

The setting feels both authentic and imaginative. I'm curious whether he based the story on actual places or let creativity take the lead.

While I loved the character interactions, some chapters felt a bit slow. Was that intentional to build suspense or just natural storytelling?

They add such an intriguing mystical element. I wonder if Hergé was influenced by any specific legends or stories when creating this plot device.
