Anyone can cover anything, but you should get some kind of back-up for your girl. The envoys could help her.

What were you thinking, having her go in and pretend to be a demon (maybe someone like the witches could help obscure her appearance, if so?) or more like pretending to transmit a message (or actually transporting one) for Deimar and keeping an eye out for what she can glean while she's there on duty?
