Guyomard
The lover of Morgan Le Fay who, in Breton tradition, betrayed her.
One story says the imprisoned Guyomard's lover's upper portion in a brazier and her lower portion in a block of ice. Another tale says she turned both Guyomard and his lover into rocks, now known as the Rocher des Faux Amants.
His home was in Cameliard.
