So what we've got so far on were-nouns is:
Werewolves are all about walking as close to the fire as possible, trying not to get burned. Werewolves have hungers, which are physical things they want, bad. They get a bonus to trying to seize them. At their Darkest Selves, they must attempt to kill or maim everything that stands in the way of their hungers.
...which territory we more or less ceded to the Ghoul in the time since the above was written. So what else can we do for our dear friends the lycra-topes?
Here's my thinking. Werewolves more than any other skin are about fear - fear of being found out, fear of losing control, fear of your literally changing self. It's the fear you feel when you wake up with a face covered in acne, writ large. It's the fear of hair growing in weird new places and that itch between your legs.
This draws more on classic horror archetypes than it does on Twilight tropes, it's true. But the fear of losing control is something we can work with, surely. Or maybe like vampires, we're talking about two skins here? The Oz and the Veruca?
