How many Black Knights (Black Wings Generals) are there really?

So people are wondering about the whole black Mage and bunnies thing. Well I have a theory. I remember reading a post by someone joking that maybe the black mage is a bunny. Well I think that there is a land either above edelstien or below the minar forest that is like mu lung in that it is ruled by animals and not humans. In this case that animal would be rabbits. I think that the black Mage comes from this land and this was the first land that he conqured. I remember reading some thing posted on the ms website around the release of Evan that said the black Nate was once a good guy who wanted to rule because the rulers of his country were court.
