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.
