Karen is a quite extroverted 23 year old lady, but she is smart enough not to speak to just anyone. She knows as much about the current situation in Arefu as most of the other residents and constantly finds herself at odds with Evan King. She likes to wander around outside her house, even at night, and does it almost defiantly to annoy the mayor. She does not believe that living in constant fear is the answer.
She stays in her home all day, unless the player has finished the Blood Ties quest and has selected the option for Vance to provide the town with security. Then she will be seen wandering around Arefu more often.
