Don't Cry for Me, Azj-Kahet

<You find a crumpled page of journal paper wrapped around a small key.> I always suspected Arax'ne was a traditionalist, but I didn't think she'd go this far. I don't know where I'm going, but I just have to get away from her. To whoever finds this, it means the worst has come to pass. This key unlocks a chest that contains all my worldly possessions. They are yours. All I ask is that you avenge me by slaying Arax'ne.
