This one is from after Dead Man's Chest, but it's still one of my favorites: The Tale of Saint William the Martyr (http://kieyra.livejournal.com/232393.html) by kieyra. Unfortunately, that's about all I have (although I'm not sure if you saw this one (http://www.fanfiction.net/s/3558432/1/) in your brave venture to ffnet).
