Lol well I was going to use the short to her advantage already, doing a bit of what you said. The dagger is a great idea though and fixes a bit of the weirdness. I am also going to do multiple AI as a challenge so I'm excited ^_^
I don't see a problem with it. The where they come from ties into a back story which I have always felt can be revealed in IC but it is not my call on wither you need it since that is the GM territory.
I can however say that it is perfectly fine to move it into the character tab and add it in if our GM wants it.
