Scientists, fearing the cataclysmic events of a polar reversal, prepared an environment for the survival of the human race. They either directly or indirectly engineered the kind of people who would make up a community fit for survival and propagation of a new world. In the main, this means characters without father/mother figures; and/or characters with skills for survival: a doctor, an engineer, a survivalist, a mercenary; and characters of sufficiently varied genetic background: african, caucasian, asian, etc. to ensure a healthy gene pool for generations.
