The Source, The Engineer, and the System (a parable inspired by songs) is about two androids who separated themselves and their whole network of androids from the Source. Once they had been renewed and redeemed from the consequences that would befall-- that is death; they were sent on a journey to erase all he bugs they had started on their first day, with the Engineer there to guide them. Watch the spreading of the gospel over the ages, through the lens of science fiction.
