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.
