Das Schattenreich der Vampire

The mix of romance and supernatural themes really kept me hooked. I wonder what inspired the balance between the two genres in this story.

The vampire society and its rules felt intriguing but also a little quick to introduce. Was this a pacing choice or something that developed as the series progressed?

The idea of a hidden world beneath ours adds so much mystery. I'm curious about what inspired that particular setting and backstory.
