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.
