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.
