Fenarian (Bronze-scaled Enterprise Science Officer)
From a dry planet, where water is scarce and intense sunlight bakes the surface. Physiologically adapted to handle extreme temperatures and arid environments. Their society is a caste based one, with inhabitants being born into one of six (Builder, Merchant, Religious, Ruler, Scholar, Warrior).
Are you talking about "Madeline"? I read somewhere that the actress suggested her character was from a planet with four suns, so I considered that she might be from Delta Capricorni, aka Deneb Algedi. (Perhaps "Algedian," to avoid confusion with other Denebs.)
Not allowed story ideas here, sorry.
Species descriptions don't constitute story ideas. A story idea is a plot, a set of events.
IIRC, Christopher suggested that the Bug Eyed Nurse was, perhaps, a Cygnian (from TAS)
I passed along the suggestion at some point, but I don't think I originated it.
