Recs Please?

Hello! First post here, hope I've got it right!

OK, so I've been reading the King and Lionheart series by Bohemia (it's brilliant, you should check it out if you haven't!) and I really love the powerful friendship between Merlin & Morgana and I have the urge to read more fics that contain that relationship.

I'm not looking for romance between Merlin & Morgana; I'm looking for fics featuring a strong & loyal friendship between the two. Other than that, I prefer slash pairings (if there's a romance) or gen fic.

Also any era-Canon, Modern, Historical-is fine.

Any help you can give is appreciated!
