Girl Genius XXVIII: Dancink! Ve is here for de dancink!

So, Zeetha found something important or at least interesting. What is it?

The most obvious answer is that it's some sort of hint as to where Skifander is. I'll be a bit annoyed if it's a map to how to get straight to the place. And evidently on the GG Patreon page, Kaja commented that this gal is Princess Neena, whom we met earlier.
