I'm looking for this fic I can't find anymore. In the story, people from the future come back and take control over Snow and the Games. They assign each person a color: one means you're alive and living in a district, another means you're alive but living outside the district, and another means you're dead. For those who are alive, they are also given the address where they live. Does anyone know the name of this fanfic and where I can read it?
