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.
