Mia is an A5III star with twelve planets.  Two are in the human habitable zone, one of which is a dry rock, the other which is covered in water on its surface, which is in turn covered over by layers of cloud cover.
From space, Proserpina looks white.  This is because of the multiple layers of cloud cover.  However, below this cloud cover, the surface looks all blue with dots of green and brown.  This is the true surface of the planet, an ocean world with occasional tropical islands.  Blithe Vallarta brings food from the surface, which it sells, but the planet has another secret hidden inside it.  Rumor has it that the Zeborno once lived here, and left behind amazing discoveries.
