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.
