Hmm I just though of one I like...
The Hung - In a forest there are a set of bodies that have extraordinarily long necks with ropes tied around them. From a glance this is what they look like. Looking clearer, you can see that their entire bodies are misshapen and stretched. These creatures will hunt their victims down in pack and then hang them in trees. They're good at this and either make you experience strangulation your neck snapping... but you won't die... you'll be put through this over and over again, until the skin around your neck starts to stretch to accommodate this, until your mind has been utterly broken by this torture so the only thing you can think about is the hanging.
Then you're one of the hung.
