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.
