I never had a name for them. No one had one either. They're just them. None of us know why they hunt us down, what is their reason. They just do. It doesn't makes sense but that's how it is, we never questioned how our cycle works. They always find us, it isn't weird after a few times. Our theory is that they get notifications when a text is send, or a location. We are always watched by them and no matter what, we cannot get out of under their thumb. They're always there, watching, hunting.
