All evil can pass with ease, But good may not do what good will please. Try and run or try and hide You'll never get yourself inside. I, the ghost, the guard of vice Will throw at you dead rats and mice. Torment to your very soul Until you leave us well alone.
Only Evil can access The Underworld this way, unless Good can distract the ghost, but be careful or you will find yourself in even more trouble than you already are in...
