Meet Lady Kundry, Gawain's third wife. She first appears in Chrétien de Troyes' Perceval, where she is not given a proper name but gets a few telling epithets instead, such as "l'Orgeuilleuse de Logres" or "la Mauvaise Pucelle". Apart from having the most alluring mouth in Christendom (as per Wolfram von Eschenbach), she also has a marvellously sharp tongue that she uses deftly to lash out at every knight she meets. She makes no exception for her future husband.
I thought she should have a proper name, so I gave her the one she has in Wagner's Parzival, even though the character in the opera is quite different from my version.
Obviously, I like Kundry an awful lot :).
