Well uh just so you know the master of the darkness won't try to take you himself he will send their cronies to get you so take that into account when you do your post. The cloaked figure that has been following you will be a cronie, your perfect description of them worked well, especially the cold chills on the one who disappeared through the wall. Iv scoured the internet and I think I found a good descriptive picture for them.
