diesel, another    
  one of earth's forbidden  
    liquids (tied strongly to   
   earth due to being made of oil   
                                
  (oil is the philosophers  
       stone, btw)      
                                  
                             ibis 
 so it's a                        
 fuel, right?                     
 we can run generators and robot  canines 
 and stuff  on this shit.  hard  to  find 
 due to  half-assed  "attempts"  to  stop 
 global warming, but  easy  to steal once 
 found -  you don't  even  have  to  hack 
 anything (might have to taste it though) 
                                          
 best  to  search   at   night,  roadside 
 trucks  and lorries are already emptied. 
 hidden  vehicle  graveyards out  in  the 
 desert perhaps,  if the  dragons  didn't 
 get  to  them   first.  people's  yards, 
 fenced  in.  those   towns   were   some 
 company    owned   (and    fenced   off, 
 important!)  entire parts  of it... they 
 would usually have a  fleet of vehicles.
