An AU I can talk about for hours - pagan god!Cas and worshiper!Dean.
About how gods aren’t supposed to have favourites but always do ; how Castiel always waits for the young freckled hunter to bring offerings to his temple.
And how he always rewards his faith with luck on hunts and good health.
How Dean grew up as a hunter believing in the same gods his family did.
How once he found the old temple in the middle of the woods and understood that he looks at something ///ancient.
How he offered milk and honey on the stone altar as an apology for walking into an old god’s home.
How he started to come there often, loving the peaceful atmosphere, always bringing something for the god whose name no one remembered anymore.
