Mamau - pronounced "ben-dith uh momay"; Carmarthenshire (Wales)
name for fairies, translates to "Mother's Blessing". Phrase is used
as a prayer to protect from evil.
A stunted and ugly clan of Welsh fairies who steal not only newborn
babies, but walking, talking children as well, substituting one of
their ugly children, the crimbils, for the child. It is possible to
get one's child back from the bendith y mamau with the help of a
witch. However, when the child returns he remembers nothing of the
experience except a notion of sweet music.
