Since we were discussing Ruritanian Romances the other week

Someone wrote this Merry Widow fic for Yuletide:

Three Times Countess Hanna Glawari Danilovitsch Saw the Vilja up the Mountain, and Lived to Tell the Tale
Summary: Hanna met the Vilja three times. The spirit of the wilderness contests with Hanna for the life of a goat, a man, and something else.
