A quest has an unexpected ending

There I was, searching in what might be a vain quest (if you are in HIST 2805, see below). A voice called out to me from a cave. There he was, the wise hermit of Arthurian lore, standing before his acolytes, expounding on chivalry. He turned to me and made his demand -- why was it that Arthur, regretting the breaking up of his Round Table as the knights prepared to quest for the Holy Grail, commanded them to perform one last great joust?

And you know, I was able to tell him!
