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.
