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.
