the dragon and the knight

~700 AD.  where a knight from al-andalus goes up to explore and make some goodwill gestures to that crazy christian kingdom in Wales led by one king arthur.  Arthur and co aren't all thrilled with this knight, who they just happen to send on what arthur's peeps think is going to be a death mission to slay a dragon...but then it turns out that the dragon actually quite likes this particular knight.
