Morgan
Morgan le Fay was a fairy queen and a sorceress,
who appears
in the Arthurian legends as Arthurs sister. Glamorgan
in Wales
is her sacred territory. She took Excalibur and
its scabbard
from Arthur and exchanged it with forgeries.
Arthur nearly died
because the scabbard didn't protect him anymore,
but managed
to retrieve both sword and scabbard.
