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.
