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.
