Nazgul on Fell Beast - howling

This Fell Beast from captainsmog isn’t just an obvious upgrade from the retrospectively inferior horses the Nazgul stole from Rohan, but a great MOC in any case. I personally far prefer the LotR sets over the Hobbit ones (with the exception of An Unexpected Gathering which is also featured in those films), so with the eagles now appearing in two sets from the line I think we really need another set featuring the black riders. Let me be more specific. How about a Battle of the Witch-King set complete with “I am no Man!” Éowyn and the King of Angmar’s trusty flying, smelly… thing.
