Karla, the Grey Witch, is an ambiguous character responsible for shaping the history of the accursed island of Lodoss. She is the only survivor of an ancient Magic Kingdom and has lived for more than 500 years. Her physical self has perished long ago, but her soul (embedded in a golden circlet) possesses a human host from time to time so that she can have a body. After the fall of the Magic Kingdom she believes the only way for Lodoss not to be destroyed is to keep a balance between peace and chaos. So when there is war, she creates peace; when there is peace, she provokes war. Karla claims that in this way Lodoss will never collapse. For these years she has been changing her hosts, watching and manipulating the history of Lodoss.
