There is a (probably wrong) theory that all Bronze Age civilizations where matriarchies, which might be where the Foglios got the idea for the Age of Queens. So it would fit that this is the Spark version of the Bronze Age.

I'm surprised that Lucrezia thinks that Albia has never really tried to understand the gates - trying to understand and improve any shiny thing that crosses their path is pretty much part of the definition of being a spark. Either Lucrezia is just trying to insult Albia or she severely underestimating her (in my opinion). Considering how surprised and insulted she is every time someone manages to defeat her, she's probably underestimating everyone.
