Wisps in the city
Big contrast to the bright, flighty little wisps you've seen in Small Trolls.

These little guys will appear in the city and they're no different to their forest versions. Except they're shriveled, sootier, grubbier and dimmer. 

Tistow is built on a marshland, meaning there used to be a lot of sprites there. They're all still there, but they've been reduced to these sorry looking creatures after their trees were cut down and fields built on.
