AU in which the pagan God Dean has to convince a pious Christan to marry him, so that a curse will be lifted off him. But convincing a Christian to marry a pagan god is harder than it seems.

You can find the lyrics and translation of Herr Mannelig which was the inspiration for this here!

(Of course Cas might still throw a “du är det värsta bergatroll” at Dean and I’m sure Dean’d go cry because that’s just so mean, Cas!)
