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.
