Nina

Nina was one of the few mortal woman who became a Guardian of Pandora's Box. Guardians were assigned the task of protecting the box from being opened by demons otherwise it would release all of the world's sorrows into the world.

Once a demon named Katya tried to take posssession of the box from Nina. Nina resisted and the two started fighting with magic and sais. One of them gets stabbed and the box moves on to the next guardian. It's later revealed that Nina died in the fight so thats why the box moved on and Katya shapeshifted into Nina and enlisted the help of the Charmed Ones to get it from the new Guardian, Hope. If Nina hadn't met her demise then she would have carefully instructed Hope about her new destiny and the dangers of the box if opened.
