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.
