A child groaned as she rolled her head, painfully, against the cold wooden floors beneath her Slowly, her eyes began to opened as she was greeted by the dark shadows of her home.. "W-what.. What happened?" She questioned as she hissed in pain, attempting to try and stand on her feet The child wobbled around the wooden floors and walked pass corpses of several people around her home All dead.. Rotting.. And half-eaten as blood stained the floors and walls near them "W-Where am I? S-So dizzy.." She groaned as she was able to reach the front door of her house only to end up collapsing from the pain she felt As was about to lose consciousness, a bright light appeared yet her vision blurred as she was getting rocked in and out from consciousness.. "Ar.. ..u ..ay?" She heard as her world went dark and her consciousness slipped into darkness..
