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.
