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.
