* post apocalypse scenario 
  * relatively slow, gradual downfall of civilization - not a fast wipe out event 
    * ppl had time to prepare
  * humanity discovers a new way to generate nuclear power some time in the 80s 
    * upsides: 
      * moar powar *(more? :p)*
      * less waste
      * comparatively straight-forward to get going
    * downsides: 
      * absolutely needs to be maintained well
      * horrible accidents 
        * huge explosions
        * scatter toxic globs of radioactive chemical sludge 
          * areas where this stuff lands turn into wasteland for centuries or millennia
        * release some toxic gas that decays slowly over time
    * power plants of this kind are built everywhere
  * as accidents happen, ppl cry for alternatives but nobody does anything about it bc it’s not economically viable
  * a bunch of wars happen and a few of the power plants blow up 
    * conventional wars, no MAD scenario
  * areas are abandoned causing civil wars in other locations due to refugee crisis
  * in the chaos, more power plants blow up making it difficult to survive at the surface due to contaminated atmosphere 
    * the rest of civilization has to wind down and disappears
* story takes place roughly 110 years after the apocalypse 
  * story starts on Tue, 2106-06-01
  * just enough time for no living memory of the "old world" to survive
  * slight retro-futurism 
    * for the most part, technology is stuck in the 80s or 90s, but there are some key differences 
      * the underground city has only electric cars
      * aforementioned nuclear power plants
      * successful cryogenic preservation
    * computing is different 
      * home computers are rare - they are similar to early to mid 90s machines but have big boy 8" floppy drives
      * business computers are mostly minicomputers or larger 
        * they are actually being used for all sorts of tasks like ordering supplies or to check inventory etc
      * computing is dominated by a UNIX-like operating system (INUX lol)
