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.
