Quote from : Walking Wolf: A Weird Western Book

But I can tell you the reason for me being so youthful-looking for a man a century and a half old. I’m not exactly what you’d call human. Hell, I’m not human at all. The closest thing you might be able to relate me to is what’s known as a ‘werewolf’, but not the kind you see in picture shows that sprout hair and teeth every time there’s a full moon. The truth of my kind is a lot more complicated—and frightening—than that.
