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.
