Rhydinspace, a Science Fantasy Setting
I have been giving thought to defining the Rhydin solar system. As Rhydin is a cross-genre campaign world, “Rhydinspace” is likewise. So science fantasy. I am starting my definition from the science end of the spectrum (e.g., space is a vacuum) and “softening” the science with fantasy only as needed.
