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.
