I first watched Princess Tutu in 2008 and it has basically been my heartsong since then.
Thus, "The Heart Within" was born. It follows the lives of Ahiru and Fakir four years after the defeat of the Monster Raven. When Fakir attempts to write Ahiru back into her human form again, he reawakens the story and forces each of them to face a new threat to Kinkan Town, all while struggling to realize their feelings for each other.
It can be found here:
www.fanfiction.net/s/4237486/1…I love that story, but in the years since then, I realized that I didn't set up it up to tell the story that I really wanted to tell. So I'm actually doing an as yet untitled rewrite with the same essence of story. So that's in the works!
