Okay, it's done (and I'm done reading it) so I can finally rec this sucker:
Two Boys from Kansas in King Uther's Court (Merlin/Supernatural crossover) by
ariadnes_stringSummary: The title kind of says it all. And this:
“Fair sir,” said the knight, or Jedi warrior, or whatever the fuck he was, “will ye just?”
“Will I which?”
“Will you try passage of arms for land or lady or for-“
“Seriously? Seriously? What, did someone drop acid in the fake mead at the Renaissance Fair? Stop dicking around, man, and fuck off.”
Now, I have only passing familiarity with Merlin, really. I know it only slightly better than I know, say, the Stargate universes, several varied comics canons, or pretty much any procedural drama -- I've touched the original canon maybe a small handful of times, but otherwise know it through fanfiction. So I think I can say with relative safety that this sucker will be entertaining even to those who know jackall about Merlin.
Share and enjoy!
ETA Also, for those wondering, it's totally gen.
