I wrote this a few years ago after looking at Engine Heart as a tabletop setting.
The book itself is basically ‘hey Why not?’
Synopsis: Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us.
- War of the Worlds, H. G. Wells
That line was first written to describe otherworldly conquerers bent on enslaving and consuming humanity. Nevermind Humanity has long since vanished in some war or other and the minds that now turn to our planet originally came from here; now, as then, that line holds true
We have Resources Mars needs; Manufacturing, Parts, Labor. They care not for the day to day struggles of the machines left to try scratching out a living. Their plans are beyond such small concerns and they will not be denied.
All that stands in there way is a trio of ambassadors sent from Mars in an earlier time, before the Machines there grew restless and Warlike. These three are really all that stand between Martian Conquest of the remains of Post-Human Earth and the scattered broken fiefdoms of AI controlled territory that are only just now pulling themselves out of the mire.
