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.
