Space Castle - Farewell To The Master

Authors inspire me constantly. I read Harry Bates' "Farewell to the Master," and instantly fell in love. I NEEDED to create his characters in my own way. So I set to work.
This here is Klaatu and Gnut's little ship- returning home to a space castle made of only God-knows-what. Of course, that wasn't mentioned in the book... But I like running with ideas. I run a little too far with them, most of the time...
