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.
