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.
