"On A Dark Ley Line Trait" Without Vampire Game Pack?

Hmm, I'm guessing it's probably that mod you're using and will most likely go away once you remove it. However, if it was there beforehand, could someone have possibly gifted you the Vampires GP and you just didn't notice when it installed? I don't know how gifting works, but it's a possibility I suppose. Perhaps it downloaded during a patch or an Origin update and went unnoticed? Just a thought... :)
