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.
