Aillena absolutely annihilated a group of grimlings attacking her and the dig site, though she doesn't seem to be very happy about it at all. In fact, she seems incredibly regretful that she acted as she did. I'm not seeing the transgression though - she very adeptly protected herself from harm. Even still she is drained, and wants to turn her attention to the dead. To that end, I'm to travel to the graveyard and clear out the undead, and then place enchanted talismans on its four corners.
