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.
