Mother Mallum

Mother Mallum is the queen of the Sea Slugs, and she plans to take over RuneScape. She already has control of the Fishing Platform and Witchaven. She first revealed herself to the world when the Slug Menace quest was released. She tried at least 4000 years ago to conquer RuneScape but was stopped by the Temple Knights. It appears that she communicates with a empty human body, during the last part of the Slug Menace quest she tries to obtain a new body to use to communicate (A.K.A. your character), though at the last minute your saved by being teleported out of the cave by the temple knights.
