Who are you?

[fairyrune]

You came to visit me at work Wednesday evening. I was not there, so you left me a note, which promptly disappeared. Apparently you're a rather attractive goth chick, you were wearing a dog collar, and I know you from faire. Co-worker Ashley described you as "scary," but that's ok, because she's just a kid. Anyway, I have no idea who you might be, and I'm curious.

...Anybody? Bueller?
