Many moons ago, I posted a wish list of fanfic challenges that contained several possible XOVERs of "Forever Knight" with some popular TV shows. Two of them crossed FK with "Xena: Warrior Princess" where, in separate stories, Nat and Tracy magically traded places with their respective ancestors Xena and Gabrielle. I was subsequently informed that standard challenge protocol required the challenger to post the first part of the story. So here it is. Do with it what you will. (But please, be kind.)
