A. I agree with the thought that 3 seas and mu seem like they are written by a different person. This is a good thing to my mind.

Harlan Ellison refers to world building as furniture. you take your house, or story, and you put your furniture into it, and it helps define the house, but no matter how much and how cool of furniture you have, you'd better have a damn interesting house at teh core, furniture or no.

He also likes to say that hes not a science fiction writer, hes a story teller, he just uses a lot of their furniture.
