The twenty-eighth genius can inform the magician of powerful formulae by which he can, for instance, cause or stop thunder and lightning, or a terrible thunderstorm, how to cause a fire over the greatest distance or how to stop or localize it, how to destroy completely whole cities and how, on the contrary, to protect towns and houses in war-time, so that they remain untouched. You need never worry about any misuse, since an immature person would never be revealed these secrets. The magician who has taken up contacts with this genius need not be afraid of anything, for he is under special protection.
