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.
