I'm interested. I'm impressed at how thoroughly you answer the questions posed thus far. 
What makes these covens special? How do they retain their political/occult power? If magic is something that is relatively common (akin to a natural force) how do they stay on top? For instance, do they have a serfdom (you said this was in a time similar to the dark ages), a common populace limited in the ways of magic due to resources and access to things like tutelage or archaic texts, reserved to toiling in the fields to stay alive in the presence of the coven? I also noticed that in your OOC snippet you made a direct distinction between an occult leader, and a political one. I guess I'm just kind of wondering about the power structure, although if you planned to release this info later, then I digress.

Other than that, I'm 100% interested in joining.
