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.
