You are in a world were females death angel took over.... they usually move alone or in a group of 2 to 3 individuals, but several times a month they return to a place called a nest, they are scattered all over the world and stay there for the next 24 hours... we don't know why they do it, why they go there and what they are doing there... all we know is that they have nests, heat, territory marking, and no eyes and only rely on hearing. they can start a family. (This is in no way related to the movies)
