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.
