Thinking -- mechanical civilizations may require a root to an organic civilization. Hmm.

I would be descended from a series of industrial, commercial, and industrial robots that survived a biological apocalypse that wiped out their creators. The big point is that they arn't all killbots. A large number are peaceful machines out to fulfill their directives in life, and their military is mostly defensive. Mostly.

EDIT: Although I do also have plans for a hyper-consumerist, hedonistic faction, also using extensive robotics. Hmm. Choices.
