There is plenty of magic that can help you change your appearance, including smell.
If you're hiding from a vampire, they might be familiar with magic, though. I'm only guessing that because you're asking about changing your smell (and there's apparently a vampire here that has everyone worried, from what I'm reading).
I'm sorry. I'm babbling at you a little. Let me try this again. Hi, I'm Tara. I can help you with magic if you really need it.
