Callisto is home to the Whedonite Fen who don't want to even pretend they're at odds with the Heinleinians on Ganymede; casual tourists often find the welcome on Callisto to be less forced than on Ganymede.
The moon is also home to a large fraction of the Anne McCaffrey Fen who have made it Up, based on it being a major location in her Tower and Hive series.
Known Places on Callisto
