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.
