The Seventh Prince

I don't think I'm ever going to get around to finishing this, so sticking it up in my scraps in case anyone wants to see. 

The idea was based on the fairytale of the princess who has seven brothers who get turned into swans, and she has to create seven shirts out of nettles to turn them back into humans.  A handsome king finds her and marries her when only six and a half shirts are finished.  So the youngest brother has to live with one arm being half a swan's wing.  The fairytale ends on "happy ever after", (since she and her king are alright Jack!), and the deformed youngest brother isn't mentioned again.

I was thinking what if Merlin was the forgotten, half-formed, youngest prince and Arthur visits the kingdom........
