About Morgause

Morgause is a popular name of a legendary queen and member of King Arthur's family in the Matter of Britain literature, where she is always a queen and usually Arthur's sibling. However, her name varies between texts and traditions, including Anna, Gwyar, or simply as the Queen of Orkney, as does the issue of her children, other than commonly Gawain. In most cases, she is the wife or widow of Lot, ruling over a northern realm such as Orkney, Lothian, Scotland, or Norway. She often has sisters, notably Morgan, with whom she is being sometimes conflated into a single character by modern authors.
