I just want to say how FREAKING AWESOME THIS IS.
I am like 80% sure that is Madame Mist, looking freaking awesome and terrifying at the same.
All those spiders are really not helping how creepy this is. Also the lack of face. And the fact that she looks like a rotting dementor who will suck out your soul with her evil spidery fangs.
And with those happy thoughts, I leave you.
