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.
