"Well," you sigh, "at least we know our hunter friend isn't opposed to using a witch or two."
"They don't think of witches who work for them as witches," Ed says softly. "Just... magic users. It's a whole thing. Don't think about it too hard. Look at this bit," he points with his toe.
You look at the ward one more time and see what Ed sees. In amongst a jumble of letters you pick out two words. "Filii Luna."
"Luna means moon right?"
You nod. "Pretty sure."
"Well..." Ed makes a face. "My guess is this thing is probably rigged to do something if a werewolf steps on it."
"Like what?"
"I dunno. It doesn't smell strong enough to hurt us. What should we do?"
