This is more of a question phase of an idea, so I don't get drilled right off the bat.
Are there going to be native lifeforms on planet Cythera?
How big are they going to be?
What type of life form are they going to be?
How much intelligence will they have.
What will they be made out of. (Ex. Carbon, Silicon, crystaline, sulfur)

There will be no life forms.  I believe this has already be discussed and shot down.

Yes it has.
