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.
