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.
