Fell Beast
 

Hi!

Does anyone know where I could find some good reference on a Fell Beast? Especially his wings, even more exact, the place where they connect to the body (the shoulder, I'm good, ain't I?) and the back spines.

Or does anyone have by any chance some good reference on his PC?
I already serched on google but it didn't give me a lot to work with...

Please...

P.S. For those who don't know what a fell beast is: It's the dragon like creature the Nazgul ride.
