Nadia DaVine

According to various legends, vampires can only enter a place if you invite them in. It's a dark and stormy night. A young woman named Nadia begs you to let her in from the storm. You reluctantly agree, due to wanting to some misplaced sense of generosity. Hours pass, as you suspect nothing. You eventually need to use the bathroom. After you get out, your family/roommates/friends that happen to be there are all dead. They're corpses bleeding on the ground, and the rest of your home in darkness with Nadia staring at you with her red demonic eyes, while bearing her vampire teeth. You decide what happens next.
