A zombie apocalypse had started about a year ago in this world. Nightmare had started a group of survivalist that were named Dust, Cross, Horror, Killer, and Error. His brother Dream also been collecting survivors, though Nightmare hates him enough to refuse to join him. Why, you may ask? Well, none of the gang knows for sure. He's always been secretive about his past and the gang is suspicious that there is something important that he is hiding. All that he would tell them is that he had a brother, that is Dream and a sister. One day, they realize that his sister survived. Will she be willing to tell his past? Is she infected too? What is her past as well?
