Winchesters: Wanted

Does anyone know of any good Merlin fanfic communities? I'm expanding my reading scope since Supernatural isn't keeping me in the manner to which I've become accustomed lately.  

Way back when I was pondering ideas for a Dean/Cas Big Bang idea (and picking one that didn't go over too well), I came up with several bizarre (or not) story prompts. Since my latest effort at writing is still being beta-ed, and I am horribly unmotivated to write these days, I figured I'd do a casual poll.


Which Dean/Cas, with some optional Jensen (not that there will be sex, but they will both be in it) should Zanne try to write? It'll be relatively new territory since I don't write much Castiel.

1. Cas is Dean’s guardian angel, and as Dean grows, Cas grows – his imaginary friend maybe? With subtle hints he might be real? – maybe Cas is Jensen’s imaginary friend? Then he shows up on set and is real?

2.  Cas/Misha is angel, but only Jensen/Dean knows. He can see wings all the time, but no one else can. Everyone else just thinks Cas/Misha is the weird guy, and Dean/Jensen’s even weirder. Could tie into #1.

3.  Jensen/Dean is an angel that is born defective (without wings), and only Cas will be his friend

4.  Jensen as geneticist, creates first successful human/avian hybrid named Cas (Certified Avian Specimen – something that makes sense). – but when does Cas stop being just an experiment and become a man? Call Jensen Father?
