Carla is a woman in West Ardougne who is upset that she lost her son to the mourners. She claims that it seemed more like the common cold rather than a horrible disease that is supposedly affecting the city, but when the mourners took her son, she was told that he had died two days later. She can be found north of the graveyard, west of the civilians.
During the Plague's End quest, Bravek recommends Carla as one of a small group of West Ardougne citizens influential enough to start an uprising. She takes part in the assault on the Mourner's headquarters in order to avenge her son.
