Merry Christmas, Mr Libra!
In my story, Kundry is the name of the lady who in Chrétien's Graal is called l'Orgueilleuse de Logres - Orgeluse in Wolfram von Eschenbach. "Orgueilleuse/Orgeluse" is an epithet and not a name, so I needed to give her a name of my own. Kundry is the name of the character in Wagner's Parsifal, where she is an amalgamation of Orgeluse and the weird-looking Grail messenger Cundrie. I have kept both characters and they are both called Kundry, for reasons that you will hopefully found out ... one day
It's true, Arthurian legend has a massive amount of characters. The difference with Ice and Fire is that the Arthurian characters were invented by many different people, whereas GRRM came up with his cast on his own. And I admit that I find his lot easier to keep track of
. At least most of them have only one name...
