   Summary

   (Working Title)

   You don't know what higher being would've allowed such catastrophe to fall unto human civilization, but after being taken away by a group of crazed looking skeletons, you feel that there isn't a higher being, or at least that you don't have a guardian angel. What were they going to do to you? Why were they keeping you alive? Why do they keep looking at you funny?
