Very well done. The atmosphere just screams ravenloft. I was walking thru there holding my breath thinking oh god whats next whats next.
Hags usually warp the surrounding lands that they inhabit so perhaps some warped animals and plants would be good additions to the area.
I was in the sewers earlier and ran into some aberrant rats that were tough little buggers. Perhaps some aberrant snakes and boars heck even some aberrant minks! "Hey look kill that mink we can get a good price for its hide. OMG!!What the hell!! The mink just ripped out Bob's throat! RUN!!!ITS GOT FANGS!!".
Now beef up the other two fanes.
